Answer:

\frac{3}{4}

Step-by-step explanation:

To determine the scale factor calculate the ratio of the corresponding sides of the image to the original, that is

scale factor = \frac{Z'Y'}{ZY} = \frac{9}{12} = \frac{3}{4}

XZ = 8 and X'Z' = 6

To find the dilation you have to divide them

6 ÷ 8 = 3 ÷ 4 = 0.75

If you rent a car for one day and drive it for 100 miles the cost is 40 dollars if you drive it 220 miles the cost is 46 dollars
densk [106]

Answer:

y = \dfrac{1}{20}x + 35

Step-by-step explanation:

Let y = cost.

Let x = number of miles.

We have two (x, y) points: (100, 40) and (220, 46).

Now we find the equation of the line that passes through those two points using the two-point form of the equation of a line.

y - y_1 = \dfrac{y_2 - y_1}{x_2 - x_1}(x - x_1)

y - 40 = \dfrac{46 - 40}{220 - 100}(x - 100)

y - 40 = \dfrac{6}{120}(x - 100)

y - 40 = \dfrac{1}{20}(x - 100)

y - 40 = \dfrac{1}{20}x - 5

y = \dfrac{1}{20}x + 35

Mia is helping her glee club raise money to fund a field trip. The glee club secided to sell pencils, which come in boxes of 100
Nitella [24]

Answer:

m = 2500b

Step-by-step explanation:

As instructed,

let b = number of boxes sold

let m = total money made.

The total money made, is a function of the number of boxes sold.

Let me break this down:

There are 100 pencils in a box;

if they sold only one box, they will get 100 X $25 = $2500;

if they sold two boxes, they will get 200 X $25 = $5000;

if they sold three boxes, they will get 300 X $25 = $7500;

Following the trend, we can deduce that money made, m = (number of boxes sold X 100 ) X $25

representing this using the variables we were given, we have

m = 100b X 25

hence

m = 2500b
