Truett made a model of the empire state building for a school project. In his model, 1 inch represents 100 feet. If the actual height of the empire state building is 1,250 feet, how tall should Truett's model be?

A. 125 inches
B. 15 inches
C. 12.5 inches
D. 8 inches
To find the height of Truett's model, we first need to calculate the scale factor.

1 inch represents 100 feet, so to find the height of Truett's model, we divide the actual height of the empire state building (1,250 feet) by the scale factor (100 feet per inch):

1,250 feet / 100 feet/inch = 12.5 inches

Therefore, Truett's model should be:

C. 12.5 inches
Of the first 25 fans who entered a baseball game, 9 were wearing hats .If a total of 300 fans are at a game, how many would you expect to NOT be wearing baseball hats

A. 192
B. 108
C. 96
D. 124
To find out how many fans are not wearing baseball hats, we first need to calculate the proportion of fans that were not wearing hats out of the first 25 fans.

Out of the first 25 fans, 9 were wearing hats, so the number of fans not wearing hats is 25 - 9 = 16.

To find the number of fans not wearing hats out of a total of 300 fans, we set up a proportion:

(16 fans without hats) is to (25 fans) as (x fans without hats) is to (300 fans)

16/25 = x/300

Cross multiply to solve for x:

25x = 4800
x = 192

Therefore, out of 300 fans, you would expect 192 fans to NOT be wearing baseball hats.

The answer is:
A. 192
The owner of a furniture store decides to reduce the price of a sofa from $800 to $560. By what percentage was the price of the sofa reduced

A. 25%
B. 30%
C. 35%
D. 40%
To calculate the percentage decrease in price, first find the amount of the decrease:

Original price: $800
New price: $560

Amount of decrease: $800 - $560 = $240

To find the percentage decrease, divide the decrease by the original price and multiply by 100:

Percentage decrease = (240 / 800) * 100 = 30%

Therefore, the price of the sofa was reduced by 30%.

The answer is:
B. 30%
