A video game designer is modeling a tower that is 320 ft high and 260ft wide. She creates a model so that the similarity ratio o
maksim [4K]
H = Tower Height = 320
W = Tower Width = 260
h = Model Height
w = Model Width

h = (1/500) * H = (1/500) * 320 = .64 feet
w = (1/500) * W = (1/500) * 260 = .52 feet

Now, we need to convert these measurements to inches.

There are 12 inches per foot.

Let x = height in inches and y = width in inches

The ratio below compares feet to inches

x / h = 12 in / 1 ft
y / w = 12 in / 1 ft

Plug in h and w, cross multiply, and solve for x and y, respectively.

x / .64 = 12 / 1
1 * x = .64 * 12
x = 7.68 in

y / .52 = 12 in / 1 ft
1 * y = .52 * 12
y = 6.24 in

I'll name you the BRAINIEST if you can answer this.The scale factor for a model is 18 cm
bezimeni [28]

Answer:

  32.625 m

Step-by-step explanation:

You have the proportion ...

  18 cm : ___ m = 22.4 cm : 40.6 m

This can be rearranged to ...

  ___ m/(18 cm) = (40.6 m)/(22.4 cm)

Multiplying by 18 cm gives ...

  ___ m = (40.6 m)·(18/22.4)

  ___ m = 32.625 m

8 x 5 ÷ 2 - (5+3) Please help
pshichka [43]
The answer is 12.
First you multiply 8 by 5, which gives you 40. Then, you divide 40 by 2, which gives you 20.
Finally, you subtract 20 by 8 because 5 + 3 = 8.
