The car consumes 3 gallons and 8.2 gallons of fuel respectively.
Milage:
Divide the distance traveled by the amount of gas used. For example, driving 100 miles with a full tank and 5 gallons of gas is 10mpg. When it comes to fuel economy, it's important to know how much your car is costing you each time we drive it.
According to the Question:
The gas mileage is the number of miles that can be covered by a car for a particular amount of fuel.
We are given that the gas mileage of the car is 30 miles per gallon, that means that the car consumes 1 gallon of fuel for each 30 miles covered.
The amount of fuel needed to cover the following distance is:
a) For 90 miles, let x represent the number of gallon of fuel. Hence:
Distance covered / amount of fuel = 30 miles per gallon
90/x = 30
⇒ x = 90/30
⇒ x = 3 gallons
b) For 246 miles, let x represent the number of gallon of fuel. Hence:
Distance covered / amount of fuel = 30 miles per gallon
⇒ 246/x = 30
⇒ x = 246/30
⇒ x = 8.2 gallons
Therefore, the car consumes 3 gallons of fuel for 90 miles and 8.2 gallons for 246 miles.

the figure above shows the inside dimensions, in feet, of a certain room. an architect made a scale model of the room that had a floor and four walls, but not a ceiling. what was the scale of the model, in inches per foot, if the inside of the model had a total surface area of 2,304 square inches?
The scale of the model is 0.00017 ft/in, or in inches per foot.
To determine the scale of the model, we need to find the ratio of the size of the model to the size of the real room. We can use the information provided about the total surface area of the model to find this ratio.
The total surface area of the model is given as 2,304 square inches. We can find the total surface area of the real room by multiplying the lengths of the four walls and the floor.
The inside dimensions of the room are given as 8 ft x 12 ft x 8 ft x 12 ft x 8 ft = 8 x 12 x 8 x 12 x 8 = 92,160 sq ft
Now we can find the ratio of the size of the model to the size of the real room by dividing the surface area of the model by the surface area of the real room and converting it to inches per foot.
2,304 sq in / 92,160 sq ft = 0.025 sq in/ sq ft
To convert square inches to square feet we divide by 144, so 0.025 sq in/ sq ft = 0.025/144 = 0.00017 ft/in
So, the scale of the model is 0.00017 ft/in, or in inches per foot.

A room 9m ×7. 5 m i covered with tile. Ize of each tile i 25 cm by 20cm. Find the cot of tile at the rate of ₹45per tile
The price to tile the room is $3,240.
We must figure out how many tiles are required to cover the floor before multiplying that number by the cost per tile to get the cost of tiling the room.
To begin, we must change the room's measurements from meters to centimeters in order to make them consistent with the tile's size. Multiplying 9 by 100 and 7.5 by 100 will yield the results we need: 9m x 100cm/m = 900cm, and 7.5m x 100cm/m = 750cm
Since the room and tile dimensions are now both expressed in centimeters, we can calculate the number of tiles required to cover the space by dividing its size by the tile's area:
25 cm × 20 cm / 36000 cm / 500 cm = (900 cm x 750 cm) / 72
In order to cover the room, 72 tiles are required. We must multiply the quantity of tiles by the price per tile in order to determine the cost:
72 tiles x 45 cents each tile = 3,240
Therefore, the price to tile the room is $3,240.

Find the measures of the angles of a triangle with one angle measuring 130 and the other two measuring x.
Answer:
x = 25 degrees
Step-by-step explanation:
The sum of the angles of a triangle is always 180 degrees. Therefore, in a triangle with one angle measuring 130 degrees, the measures of the other two angles must add up to 180-130 = 50 degrees.
So, if the measures of the other two angles are x, the equation would be:
x + x = 50
This means that the measure of each angle is 50/2 = 25 degrees.
Therefore, in a triangle with one angle measuring 130 degrees, the measures of the other two angles are both 25 degrees.

(A) P(AB) = P(A B) = 0.5 denotes that there is a 0.5 chance that occurrences A and B will occur simultaneously. We cannot tell whether this relationship holds true for these specific events because the provided information does not specify whether A and B are independent or mutually exclusive.
(b) P(A'B) = P(A') + P(B') - P(A'B') = 0.6 denotes that there is a 0.6 chance that events A and B will occur together.
(c) The chance that either the complement of event A or the complement of event B will occur is 0.5. P(A'B') = 1 - P(AB) = 1 - 0.5 = 0.5.
(d) P(A|B) = P(AB) / P(B) = 0.5 / 0.2 = 2.5 denotes that there is a 2.5 percent chance that event A will occur provided that event B has already occurred.
If P(A) = 0.4 and P(B) = 0.2, respectively, then A and B are independent events.
(a) P(AB) is the probability that both occurrences A and B will occur at the same time. It is calculated as P(A) * P(B) = 0.4 * 0.2 = 0.08. The likelihood that A will occur is independent of the likelihood that B will occur since the two events are unrelated.
(b) P(A'B) = P(A') * P(B) = (1-0.4) * 0.2 = 0.12 is the likelihood that events A and B will occur in complement.
(c) The probability that either the complement of event A or the complement of event B will occur, or both, is given by P(A'B') = 1 - P(A'B) = 1 - 0.08 = 0.92.
(d) P(A|B) = P(AB) / P(B) = 0.08 / 0.2 = 0.4, which represents the likelihood that event A will occur in the absence of event B.
if P(A) = 0.4 and P(B) = 0.2, respectively, and A and B are events that cannot coexist.
(a) P(AB) = 0 (by definition of mutual exclusion), indicating that there is no chance that events A and B will occur simultaneously.
(b) The probability that event A's complement, event B, will occur is P(A'B) = P(B) = 0.2.
(c) The probability that either the complement of event A or the complement of event B will occur, or both, is P(A'B') = P(A') + P(B') = 0.6.
(d) Since P(AB) = 0, the probability of event A occurring provided that event B has already occurred is undefined. P(A|B) = P(AB) / P(B) = 0 / 0.2 = undefined.

Construct the following quadrilateral
Rhombus BEND
BN = 5.6 cm
DE = 6.5 cm
Answer:
Step-by-step explanation:
To construct this rhombus, we will need a compass and a straightedge.
Step 1: Using the compass, draw two arcs intersecting at point E with the radius of 5.6 cm from B and D respectively.
Step 2: With the same radius, draw two more arcs intersecting at point N from both sides of point E.
Step 3: Draw a straight line from D to E and from E to N.
Step 4: Now draw a line from B to N with the same radius used in Step 2.
The resulting shape is the rhombus BEND with side lengths of 5.6 cm and 6.5 cm.
This is a parallelogram. y = ___
The value of y in the parallelogram is 120^o.
Properties of a parallelogram.A parallelogram is a plane figure which has opposite sides to be equal. Some of its properties are:
i. Opposite sides are equal in length
ii. It has two diagonals
iii. Sum of adjacent angles is 180^o
The value of y in the diagram can be determined as;
m<ADC + m<DCB = 180^o (sum of adjacent angles is 180^o)
(x + 8) + 3x = 180
4x = 180 - 8
= 172
x = 172/ 4
= 43
x = 43^o
So that;
m<ADC = x + 8
= 43 + 8
= 51^o
Therefore,
m<ADC + m<DAB = 180^o
51^o + (y + 9) = 180^o
y + 60 = 180
y = 180 - 60

Senor Pena found some change on the floor while cleaning a classroom. He found a total of 6 coins that consisted of quarters and nickels. If the total change was $1.30, how many of each coin did he find?
Answer:
There are 5 quarters and 1 nickel
Step-by-step explanation:
Let Q and N be the numbers of Quarters and Nickels that Senor Pena found, respectively.
The value of each coin is $0.25 for quarters and $0.05 for each nickel
The total of $1.30 would be the result of:
1) Quarters: $0.25*Q, and
2) Nickels: $0.05*N
So we can write: $0.25*Q + $0.05*N = $1.30
We also know he found 6 coins, so:
Q + N = 6
We have two equations and two unknowns. We can use substitution to find the answer.
Rearrange the second equation to isolate one of the two variables. lets isolate Q:
Q = 6-N
We can use this definition of Q in the first equation by substitution:
$0.25*Q + $0.05*N = $1.30
$0.25*(6-N) + $0.05*N = $1.30
Leaving off the $ signs for clarity:
0.25(6-N) + 0.05N = 1.30
1.5 - 0.25N + 0.05N = 1.30
-0.2N = -0.20
N = 1
There is 1 nickel
Since Q = 6-N, Q = 5
There are 5 quarters and 1 nickel
CHECK
Do 5 quarters and 1 nickel add to $1.30?
5*($0.25) + 1*($0.05) = $1.30?
$1.25 + $0.05 = $1.30 YES
Find m∠S in rhombus RSTU
Answer:
In a rhombus, opposite angles are equal, therefore:
m∠S = m∠U = a + 62 degrees
And
m∠R = 2a - 80 degrees
The opposite angles of a rhombus are supplementary, meaning they add up to 180 degrees. So,
m∠S + m∠R = 180 degrees
Therefore,
a + 62 + 2a - 80 = 180
Solving for a, we get:
a = 59
So,
m∠S = a + 62 = 59 + 62 = 121 degrees

Radius r Central Angle θ 16 inches 240°Find the length of the arc on a circle of radius r intercepted by a central angle θ. (Round your answer to two decimal places.)Radius r Central Angle θ
16 inches 240°
The length of the arc intercepted by the central angle of 240 degrees on a circle with a radius of 16 inches would be 67 inches (rounded to two decimal places)
To find the length of an arc on a circle intercepted by a central angle, we can use the formula: arc length = (θ / 360) * (2 * π * r)
where θ is the measure of the central angle in degrees, π is approximately 3.14, and r is the radius of the circle.
In this case, we are given a circle with a radius 16 inches and a central angle of 240 degrees. Plugging these values into the formula, we get:
arc length = (240 / 360) * (2 * 3.14 * 16) = (2/3) * 100.48 = 67 inches
So the length of the arc intercepted by the central angle of 240 degrees on a circle with a radius of 16 inches would be 67 inches (rounded to two decimal places)
Therefore, the length of the arc would be 67 inches.

On solving the provided question, we can say that permutation will = 1/2(26) = 13 ways
what is permutation?The permutation of a set in mathematics is essentially the rearranging of its elements if the set is already ordered, or the arrangement of its members in a linear or sequential order. The act of altering the linear order of an ordered set is referred to as a "permutation" in this context. The mathematical calculation of the number of possible arrangements for a given set is known as permutation. Permutation, in its simplest form, refers to the variety of possible arrangements or orders. The placement of the elements matters with permutations. The placement of items in a specific order is known as a permutation. Here, the set's components are sorted in either chronological order or linear order.

An infinite geometric series has first term -3/2 and sums to twice the common ratio. Find the sum of all possible values for the common ratio.
The sum of all possible values for the common ratio is -1/2.
The formula for a convergent infinite geometric series is: Sum = a / (1 - r)
where a = first term and r = common ratio.
Given that,
The first term = -3/2 => a = -3/2
Since it sums to twice the common ratio, Sum = 2r.
Putting these together ---> 2r = (-3/2) / (1 - r)
multiplying both sides by 1 - r:
2r(1 - r) = -3/2
multiplying both sides by 2:
4r(1 - r) = -3
multiplying out the left-hand side:
4r - 4r2 = -3
rearranging the terms:
0 = 4r2 - 4r - 3
factor:
0 = (2r - 3)(2r + 1)
Either r = 3/2 or r = -1/2
Since an infinite geometric series converges only when -1 < r < r, the possible answer 3/2 must be rejected.
Thus, r = -1/2
Therefore, the sum of all possible values for the common ratio is -1/2.

The length of a rectangle is shown below:
On a coordinate grid from negative 6 to positive 6 on the x-axis and on the y-axis, two points A and B are shown. Point A is on ordered pair 1, 3, and point B is on ordered pair negative 1, 3. A straight line joins points A and B.
If the area of the rectangle to be drawn is 10 square units, where should points C and D be located if they lie vertically below the line that connects B and A, to make this rectangle? (5 points)
( the image is attach below)
C(−1, 1), D(1, 1)
C(−1, −2), D(1, −2)
C(−1, 5), D(1, 5)
C(−1, −7), D(1, −7)
The coordinates of the points C and D are:
C = (1, -2), D = (-1, -2).
What is cartesian coordinate system?
A Cartesian coordinate system in a plane is a system of coordinates that uniquely identifies each point by a pair of numerical coordinates. These numerical coordinates are the signed distances from two fixed perpendicular oriented lines to the point, measured in the same unit of length.
Given:
The coordinates of A and B are A(1, 3) and b(-1, 3).
We have to find the coordinates of point C and D.
We know that C and D are directly below A and B respectively. So the x-values must coincide.
Then we can say that:
C = (1, y)
D = (-1, y)
Now, remember that for a rectangle of length L and width W the area is:
A = W*L
In this case, the length is AB, then:
L = 1 - (-1) = 2
And the area is 10 square units, so:
10 = W*2
10/2 = W = 5
This means that:
AC = BD = 5
So the difference between the y-component of A and the y-component of C is 5 units
3 - y = 5
3 - 5 = y = -2
Hence, the coordinates of the points C and D are:
C = (1, -2), D = (-1, -2)

here are two plants (A and B) in an industry. To reduce pollution, the government has imposed environmental standards forcing each plant to cut emissions by 60%. At the emissions standard, the marginal social benefit of pollution for Plant A is $500 and the marginal social benefit of pollution for Plant B is $125. The same level of pollution can be achieved at a lower cost by
To achieve the same level of pollution at a lower cost, the government could adjust the environmental standards for each plant based on their respective marginal social benefits of pollution.
The government's environmental standards require Plant A and Plant B to reduce their emissions by 60%. The marginal social benefit of pollution for Plant A is $500 and the marginal social benefit of pollution for Plant B is $125. This means that the benefit of reducing one unit of pollution for Plant A is $500, while for Plant B is $125.
This information suggests that Plant A has a higher marginal social benefit of pollution than Plant B. Since the government's standards require both plants to reduce emissions by the same percentage, Plant A will have to reduce a greater amount of pollution than Plant B to reach the same level of emissions. This means that the cost of reducing pollution for Plant A will be higher than the cost of reducing pollution for Plant B.
To achieve the same level of pollution at a lower cost, the government could adjust the environmental standards for each plant based on their respective marginal social benefits of pollution. For example, if Plant A has a marginal social benefit of $500 and Plant B has a marginal social benefit of $125, the government could require Plant A to reduce its emissions by 50% and Plant B to reduce its emissions by 70%. This would achieve the same level of pollution while minimizing the cost of reducing pollution for both plants.
Thus, To achieve the same level of pollution at a lower cost, the government could adjust the environmental standards for each plant based on their respective marginal social benefits of pollution.

trish goes to a bar with six friends to celebrate her 25th birthday. they're ready to party. each of her friends order her a 1.5 oz. shot (37% abv), and she takes all of them within half an hour. she weighs about 155 pounds. what is her bac level? should she drive?
She should not drive due to her BAC level of 0.117 percentage , which is above the legal limit in most states.
1. Calculate total amount of alcohol consumed:
1.5 oz. x 6 shots
= 9 oz.
2. Calculate amount of alcohol in grams:
9 oz. x 28.35 g/oz.
= 254.15 g
3. Calculate BAC:
(254.15 g/10,000 mL) x (155 lbs x 0.45359 kg/lbs) x (1g/1000mg) x (1.2 g/dL)
= 0.117% BAC
The amount of alcohol consumed by Trish was 9 oz. of 37% abv (alcohol by volume) liquor, which is equivalent to 254.15 g of pure alcohol. To calculate her BAC, we need to convert her weight to kilograms and then multiply the amount of alcohol consumed by her weight, taking into account that there is 1.2 g of alcohol per deciliter of blood. After doing the calculations, we can see that Trish's BAC level is 0.117%, which is above the legal limit for driving in most states, so she should not drive.

Solomon has some electronics his parents said he could recycle, marcus has permission to recycle some small
household appliances, they looked online and discovered that the local recycling center offers $0.60 per pound
for the appliances and $1.50 per pound for the electronics. but there is a $27 hazardous waste fee that has to
be paid to recycle electronics, no matter how much you recycle.
The pounds that they would have to each recycle so that they earned the same amount of money from the recycle center is 30 pounds.
Equations that depict the revenue from recycling electronics and appliances are:
The following calculation can be used to calculate how much money Solomon can make by recycling appliances:
p = $0.60a
Solomon's potential earnings from recycling electronics are represented by the equation p = $1.50e - $27.
Here,
p = amount earned
a = pounds of appliances recycled
e = number of electronics recycled
The equation that depicts Solomon's earnings when he makes the same amount of money would be the same as the equation that describes his earnings when recycling gadgets.
$1.50e - $27 = $0.60e
To determine the number of pounds:
Combine and add similar terms
$1.50e - 0.60e = $27
$0.90 = $27
Dividing both sides of the equation by 0.9, we get
$27/ 0.9 = 30 pounds
