Q:
# Iris is building a model of the Washington Monument. Her model measures 15 in. tall and is 1.5 in. wide at the base. The actual width measurement at the base of the Washington Monument is about 55 ft. About how tall is the Washington Monument?

Accepted Solution

A:

Using how tall it is over how wide

=>tall/wide

The model 15in/1.5in

The actual x/55ft

Convert everything into the same units so 55ft to inches

There are 12in in 1ft

55ft * 12in/1ft

The ft cross out leaving in

55*12in= 660 in

So

15in/1.5in = x/660in

Now solve for x my multiplying both side by 660in

660in *15in/1.5in=x

x= 6600in tall

=>tall/wide

The model 15in/1.5in

The actual x/55ft

Convert everything into the same units so 55ft to inches

There are 12in in 1ft

55ft * 12in/1ft

The ft cross out leaving in

55*12in= 660 in

So

15in/1.5in = x/660in

Now solve for x my multiplying both side by 660in

660in *15in/1.5in=x

x= 6600in tall
