Jack bought 7 apples for $1.00. The cost y varies directly with the number of apples x. Write a direct variation equation that represents this relationship. How much would Jack pay for 12 apples?

Step-by-step explanation:

7 apples for $1.00  is .142857 an apple

.142857*12=1.71

7:1    12:1.7

all the angles opposite to the angle 150 would be 150 and all the angles that are next to 150 are 30 because they equal 180 it you add it up.

step-by-step explanation:

option a is correct.

step-by-step explanation:

scale factor: it is used to find proportional measurements.

proportions means having the same ratio.

scale factor is the ratio of the model measurement to the actual measurement in a simplest form.

or we can say that the ratio of any two corresponding lengths in two similar geometric figures

if the scale factor is more than 1, then it is an enlargement,

if the scale factor less than 1, then it is a reduction.

given the two geometric figure:

by definition of proportions, we have
