A model rocket was built using a scale factor of 1:15 if the height of the actual rocket is 9.9m, what is the height of the mill

beks73 [17]

Answer:

660 mm

Step-by-step explanation:

we know that

The scale factor is $\frac{1}{15}$

That means

1 unit in the model represent 15 units in the actual

1 m in the model represent 15 m in the actual

To find out the height of the model rocket, divide the height of the actual rocket by 15

$9.9\ m=\frac{9.9}{15}= 0.66\ m$

Convert m to mm

Remember that

$1\ m=1,000\ mm$

To convert meters to millimeters, multiply by 1,000

$0.66\ m=0.66(1,000)=660\ mm$
