Julie made a scale drawing of a helicopter. She used the scale 1 in = 4 ft. If the helicopter’s rotors are 15 feet long, how lon
g are they in her drawing?
Solve the equation to find out how long the rotors are in her drawing.
Please show your work, I will mark brainiest and send thanks on their profile if it is correct!
1 answer:
To answer this, you will start with the scale of 1 in:4 ft. I suggest writing in fraction form -see picture.
Make this equivalent to x:15 ft (also in fraction form).
To set this up as an equation use cross products (multiply the diagonal sides)-see picture.
Then solve the equation by dividing both sides by 4.
Her rotors are 3.75 inches in her drawing.

Answer:20
Step-by-step explanation:
6! = 6 * 5 *4*3*2*1 =720
8p5 = 8*7*6*5*4 = 6720
12C4 = (12p4)/4! = (12*11*10*9)/4*3*2*1 = 495
