Molly is designing a new drone for the air force. the drone is supposed to be 30 feet long and 4 feet tall. she is building a prototype for testing that will be 12 feet long. how tall should the prototype be?

 Height of drone prototype = 1.6 feet

Step-by-step explanation:

Original length of drone = 30 feet

Original height of drone = 4 feet

Length of drone prototype = 12 feet

Ratio of original length to prototype length

So ratio of original height to prototype height = 2.5

That is

      Height of drone prototype

step-by-step explanation:

always plug in x. in this case, x equals 4.

i'm going to first solve 4(2+3x)

1) 4(2+3(4)) use pemdas to solve.

i'm going to multiply whats in the parenthesis first, so 3 times 4=12.

2)4 (2+12) i'm then going to multiply 4 by both numbers in the parenthesis (because multiplying comes before adding)

4 times 2= 8.   4 times 12= 48

4) (8+48)= 56 (answer)

i'm then going to solve 8+12x and plug in 4 for x.

1) 8 +12(4)

multiplying comes before adding, so i'm gonna multiply 12 and 4.

12 times 4= 48.

2) 8+48=56

both equal the same!

8 2/3 is the answer

step-by-step explanation: just use a calculator
