Answer:

$37,500

Step-by-step explanation:

There are 10 lots of 100g in 1kg

so $150 * 10 = $1,500 per kg

$1,500 * 25 = $37,500

Based on the line on the graph, the price per gallon at Miguel's Gasoline Station is equal to: B. $2.50

In order to calculate the price per gallon at Miguel's Gasoline Station, we would have to determine the slope of the line representing the number of gallons bought and the total cost of their purchases are plotted on the graph below (see attachment).

Mathematically, the slope of any straight line can be calculated by using this formula;

Slope, m = (Change in y-axis, Δy)/(Change in x-axis, Δx)

Slope, m = (y₂ - y₁)/(x₂ - x₁)

By critically observing the graph (see attachment), we can logically deduce that the line passes through the following points:

Substituting the given parameters into the formula, we have;

Slope, m = (20 - 10)/(8 - 4)

Slope, m = 10/4

Slope, m = 2.5

Answer:

Step-by-step explanation:

width:length =1:3

width:15=1:3

width =5

The width of the actual car is 45 feet.

Given that,

A automobile model is 3 feet long and 1 foot wide. Considering that the automobile is 15 feet long

To find : The width of the actual car

Model Car's Width (W) = 1 foot

Model Car's Length (L) = 3 feet

Actual Car's Length (l) = 15 feet

Actual Car's Width (w) = x feet

To solve,

We know that,

Product of Means = Product of Extremes which means ,

1 : 3 :: 15 : x

1 * x = 15 *3

x = 45.

Therefore, the Actual Car's Width (w) is 45 feet.

The two triangles called congruent if two sides the associated angle in one triangle is congruent with two sides and the contained angle in the other triangle.

According to the Side-Angle-Side theorem of congruency, two sides and the angle they produce are congruent if they are equivalent to two sides as well as the angle of another triangle.

Thus, two triangles are termed to be comparable if their two sides are in the same ratio as the two sides of some other triangle and their two sides' angles inscribed in both triangles are equal.

The Domain is R i.e all real numbers and the range is [-16,∞).

What is the domain and range of function?

A function's domain and range are its components. A function's range is its potential output; its domain is the set of all conceivable input values. Domain, Function, and Range. If a function f: A B exists that maps every element in A to an element in B, then A is the domain and B is the co-domain. The image of an element 'a' under a relation R is provided by 'b,' where (a,b) R. The set of photographs makes up the function's range.

f(x)=x²-4x-12  

For Domain it can take all the real numbers as there is no term in the denominator. so Domain is "R"

Range will be f(x) is minimum at x = 2 i.e. f(x=2) = -16

k = 5 (or) k = -6.5

Step-by-step explanation:

Given equation,

→ -5|3 + 4k| = -115

Then the value of k will be,

→ -5|3 + 4k| = -115

→ |3 + 4k| = -115/-5

→ 3 + 4k = 23 || → 3 + 4k = -23

→ 4k = 23 - 3 || → 4k = -23 - 3

Answer: 422.39

Step-by-step explanation:

To find the shaded region (I'm assuming it's the area inside the circle but outside the rectangle), subtract the area of the rectangle from the area of the circle.

The formula for circle area: πr^2

r is the radius, and it is given that r = 12, so the area of the circle is:

π * 12^2    --->    144π    is the area of the circle

Next, find the area of the rectangle: 3 * 10 = 30

Finally, find subtract the area of the rectangle from the area of the circle to find the shaded region:

144π - 30 ≈ 422.39

The new digital camera that creates photos that are best printed at 4 inches by 6 inches will minimize.

The ratio is defined as a relationship between two quantities, it is expressed as one divided by the other.

Since the aspect ratio of 4:6 is closer to that of an 11-inch by 14-inch frame (which is approximately 1:1.5) than the aspect ratio of 3.5:5 (which is approximately 7:10).

By minimizing the difference in aspect ratio between the photo and the frame, you will minimize the loss of the edges of the picture when trying to fit it into the frame.

They are congruent by SAS as follows if I understand you correctly:

Since x is shared by both NR and AG, it must be at their intersection.

Because it lies in the middle of both, NX = XR and AX = XG.

We join point A to point N and point R to point G to complete the triangles (any 2 points define a line).

Due to the fact that there are two triangles on either side of the point X, angle AXN is perpendicular to angle RXG. Angle AXN is equal to angle RXG because the vertical (opposite) angles formed by two intersecting lines are equal.

The following is how the SAS evidence of congruency is established:

Angle RXG in triangle RXG and angle AXN in triangle AXN are congruent (vertical angles)

Triangles AX in AXN and XG in RXG are congruent (midpoint X of line AG created these).

Triangle RXG and triangle AXN's NX and XR are congruent.

By SAS, triangles are congruent. this means they have two corresponding sides that are congruent and the angle between those 2 corresponding sides is congruent also.

If a gallon of water contain 128 fluid ounce and a rain barrel can hold 6,400 ounce of rainwater, then the number of gallons of water that can the barrel hold is 50 gallons

A gallon of water in ounce = 128 ounce

Number of ounce of water that rain barrel can hold = 6400 ounce

To find the number of gallon of water we have to apply division

number of gallons of water that can the barrel hold = Number of ounce of water that rain barrel can hold / A gallon of water in ounce

= 6400 / 128

= 50 gallons

Hence, if a gallon of water contain 128 fluid ounce and a rain barrel can hold 6,400 ounce of rainwater, then the number of gallons of water that can the barrel hold is 50 gallons

1  is the value of cat in linear equation.

What is an explanation of a linear equation?

number of cats  =  n

number of fleas per cat  =  2n

total number  of fleas  =  (number  of fleas per cat) * (number of cats)   =   2n * n   =   2n2

If we take the total number of fleas, subtract the fleas of two cats, then subtract  3  for every remaining cat, we get half the total number of fleas.

(total number of fleas) - 2(number of fleas per cat) - 3(n - 2)  =  (total number  of fleas)/2

2n2  -  2(2n)  -  3(n - 2)   =   (2n2)/2

2n2 - 4n - 3n + 6   =   n2

                                               Subtract  n2  from both sides and combine like terms.

n2 - 7n + 6  =  0

                                                Factor the left side

(n - 6)(n - 1)  =  0

n = 6      or      n = 1

Answer:

The perpendicular slope is the negative reciprocal of the original slope:

For example: the perpendicular slope for y/x is -x/y

In this case, we want the slope from x +4y = 28

x +4y = 28

4y = 28 - x

y = 7 -x/4

so the answer is: 4/x

The equation of the line is - 175 x + 2 y = - 500

From the question, we have

Point 1 :

x-coordinate, x1 = 6

y-coordinate, y1 = 275

Point 2 :

x-coordinate, x2 = 8

y-coordinate, y2 = 450

We know that,

y-275 = (275-450)/(6-8)*(x-6)

y-275 = 175/2*(x-6)

- 175 x + 2 y = - 500

Slope of a Line :

A line's slope in mathematics is defined as the ratio of the change in the y coordinate to the change in the x coordinate.

Both the net change in the y-coordinate and the net change in the x-coordinate are denoted by y and x, respectively.

As a result, m = change in y/change in x = y/x is the formula for the change in y-coordinate with respect to the change in x-coordinate.

where "m" represents a line's slope.
