Uma makes a scale drawing of a patio. The drawing below shows the two scales she used to plan two patios of different sizes.

Scale 1: 1 centimeter = 3 meters. Scale 2: 1 centimeters = 4 meters. Triangle A B C. Side A is 9 centimeters, side B is 12 centimeters, and side C is 15 centimeters.
Which shows the correct lengths of side C in both scales?
Scale 1: 45 m; Scale 2: 60 m
Scale 1: 60 m; Scale 2: 45 m
Scale 1: 36 m; Scale 2: 27 m
Scale 1: 27 m; Scale 2: 36 m

then
Which is the scale factor proportion for the reduction shown?

then
Sienna planned a rectangular pool, as shown in the scale drawing below.

A rectangle with length 11 inches and width 7 inches.
She decides to change the length, the longer side of the pool, from 22 ft to 27.5 ft. Which expression finds the change in the scale factor?

Scale 1: 45 m; Scale 2: 60 m

Explanation:

All you do is multiply 15 centimetres by each metre value on each scale to get the above scale.

* Now, you NEVER included expressions, but I did my very best to predict the above imagery.

I am joyous to assist you anytime.

the system of inequalities is

step-by-step explanation:

step 1

find the equation of the dashed line

we have the points

(0,0) and (3,1)

the line passes through the origin, so, is a direct variation

find the slope

the equation of the dashed line is

the solution of the inequality a s the shaded area above the dashed line

therefore

the equation of the inequality a is

step 2

find the equation of the solid line

we have the points

(4,0) and (0,4)

find the slope

the equation of the solid line is

the solution of the inequality b s the shaded area below the solid line

therefore

the equation of the inequality b is

step 3

the system of inequalities is

the 8 in 8,420 is in the thousands place so it's value is 8 thousand.

the 8 in 6,870 is in the hundreds place so it's value is 8 hundred.

divide 8000 by 800 to find the answer:

8000 / 800 = 10

the 8 in 8,420 is 10 times greater than the 8 in 6,870
