The scale model of a skyscraper being built is 4.2 feet tall. When it is finished, the skyscraper will be 525 meters tall. What
luda_lava [24]
There are two scales that may be possible for this scale model; one where it's for every foot and one where it's for every meter.
The for every foot would be better to find out since the scale would be easier to use.
First, you have to divide each sided by 4.2, since you want to find how many meters for each foot.
4.2 \div 4.2 = 1 \\ 525 \div 4.2 = 125
For every 1 foot used in the model, the actual will be 125 meters.
1 ft = 125 m

Answer:

h=12.5\ in

Step-by-step explanation:

we know that

The surface area of a square prism is given by the formula

SA=2(b^2)+4bh

where

b is the length side of the square base

h is the height of the prism

we have

b=5\ in\\SA=300\ in^2

substitute

300=2(5^2)+4(5)h

solve for h

300=50+20h\\20h=300-50\\20h=250\\h=12.5\ in

the monthly budget for the front of the house is $18,000. you spent 9% of the budget on fresh flowers. How much did you spend on
Kipish [7]

To find how much was spent on fresh flowers, we just multiply 9% to the monthly budget, which is $18,000.

To multiply a percent to a number, we must first turn the percent into a decimal. Just divide the percent by 100 to get the decimal form. 9% is 0.09.

0.09 \times 18000 = 1620

$1620 was spent on fresh flowers (that's quite a lot of money!)
