WILL MAKE BRAINLIEST! Find the solution to the system of equations. Round to the nearest tenth if necessary.
Answers
Answer:
The solution to the system of equations g(x) = x - 1 and f(x) = x^2 - 5 is the point where the two functions intersect, which is the point (1,0).
To confirm this, we can substitute x = 1 into each equation and see that they both equal 0:
g(1) = 1 - 1 = 0
f(1) = 1^2 - 5 = -4 + 1 = -3 = 0
So (1,0) is the solution to the system of equations.

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?
Answers
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

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)

Answers
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.

Answers
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.

Find m∠S in rhombus RSTU
Answers
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

Answers
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.

Find the measures of the angles of a triangle with one angle measuring 130 and the other two measuring x.
Answers
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.

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?
Answers
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
Answers
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.

(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.

20 children lineup to ride go carts.The go cart operator collects two dollars from each child in order from the first to the 20th in line. do the ordered pairs (child number, amount paid) represent a function? explain your reasoning.
Answers
Yes, the ordered pairs (child number, amount paid) represent a function.
What is a function?A function is a relationship between inputs where each input is related to exactly one output.
Example:
f(x) = 2x + 1
f(1) = 2 + 1 = 3
f(2) = 2 x 2 + 1 = 4 + 1 = 5
The outputs of the functions are 3 and 5
The inputs of the function are 1 and 2.
We have,
Number of children = 20
Cost per children = $2
Now,
The ordered pairs are:
(1, 2), (2, 4), (3, 6), (4, 8), (5, 10), (6, 12), (7, 14), (8, 16), (9, 18), (10, 20),
(11, 22), (12, 24), (13, 26), (14, 28), (15, 30), (16, 32), (17, 34), (18, 36), (19, 38), (20, 40)
The ordered pairs are a function.
A function can be one-to-one or many-to-one but not one-to-many.
We see that the ordered pairs are one-to-one.
Thus,
The ordered pairs are functions.

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.
Answers
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.

a square pavement has a side length of 50 m. how many square tiles, each of side length 5 m, are needed to tile the pavement?
Answers
The required number of tiles required is 100
as per detail stated above,
the length of the side of the square tile is (s) = 5m
the length of the side of the square pavement (S) is 50m
the area of square tile whose side length is 5 m is
area = side (s) times side (s)
area = 5 x 5
area = 25
now the second area
the area of the square pavement whose side length is 50m is
area = side (s) times side (s)
area = 50 x 50
area = 2500[tex]m^2[/tex]
now to find
the required number of tiles = area of the square pavement by the area of the square tile
therefore
the required number of tiles are =
=> 2500/25
=> 100
therefore the required number of tiles are 100.

PLEASE HELP I NEED TO FINISH BY TONIGHT
Answers
The linear model that represents the amount of fuel on the plane is F(h) = 63,500 - 7937.50h
What is the linear function ?A linear function is a function that has a single variable raised to the power of 1. A linear function increases or decreases by a constant value . As the flight time increases , the amount of fuel declines . Thus, the linear function would be a decreasing function .
The form of the linear function is:
Total fuel left = capacity of the plane - (fuel consumed peer hour x number of hours )
Total fuel left = 63,500 - [(63500 - 55562.5) x h]
F(h) = 63,500 - 7937.50h

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.
