Answer:

<em>The actual airplane is 25 ft long</em>

Step-by-step explanation:

<u>Scaling</u>

Objects can be represented in a reduced or augmented size by using scaling which is basically multiplying or dividing by a constant factor.

The scale used to draw an airplane is:

2 in = 5 ft

The scale factor is, then:

5 ft / 2 in = 2.5 ft/in

The actual airplane's length can be obtained by multiplying the scaled size by the scale factor:

10 * 2.5 = 25 ft

The actual airplane is 25 ft long

The smaller triangle was dilated to form the larger triangle. What is the value of x?
strojnjashka [21]

Answer:

The value of x is 14

Step-by-step explanation:

The value of x is 14 because the smaller triangle was dilated by 3 to get the bigger triangle. I figured this out because

9 ÷ 3 = 3

so this would mean that 5 was dilated by 3 also. So to figure this out, it would be

5 × 3 = 15

1 of that 15 is already there.

So this means that

15-1=14

A=14

I hope this helps you.
