Can any one solve this math 7a equation

12). Length in the actual will be 6.25x12=75 in

13). Length in the model will be 15/12=1.25 ft

14). depth in the actual will be 32x12=384 cm

15). Width in the actual will be 5.4x12=64.8 ft

16). Diameter in the model will be 21/12=1.75 cm

Step-by-step explanation:

Given table show relation between model and actual prototype.

It is given that the actual prototype is scaled by 12 of the model.

I.e. Model x 12 = Actual.

12).

For mattress,

Length in the model is 6.25 in.

Length in the actual will be 6.25x12=75 in

13).

For corvette,

Length in the actual is 15 ft

Length in the model will be 15/12=1.25 ft

14).

For Water tower,

depth in the model is 32 cm in.

depth in the actual will be 32x12=384 cm

15).

For wingspan,

Width in the model is 5.4 ft

Width in the actual will be 5.4x12=64.8 ft

16).

For Football helmet,

Diameter in the actual is 21cm

Diameter in the model will be 21/12=1.75 cm
