If you would like to know how many gallons of paint will Henry need to paint his living room, you can calculate this using the following steps:
the ceiling: 24 ft * 18 ft = 432 ft squared
walls: 2 * 24 ft * 9 ft + 2 * 18 ft * 9 ft = 2 * 24 * 9 + 2 * 18 * 9 = 432 + 324 = 756 ft squared
432 ft squared + 756 ft squared = 1188 ft squared
1 gallon of paint ... 450 ft squared
x gallons of paint = ? ... 1188 ft squared
1 * 1188 = 450 * x
1188 = 450 * x /450
x = 1188 / 450
x = 2.64 gallons of paint
The correct result would be 2.64 gallons of paint.
Answer:
6 inches
Step-by-step explanation:
The formula for the area of a triangle is
b - base
h - height
the first step is to add the information that we know into the formula.
We know the area = 
and the height = 5 inches
if we had both the base and the height, the next step would be to multiply
b x h then half the answer to work out the area but as we already have the area (
) we need to work in reverse.
15 x 2 = 30
what is 5 multiplied by to get 30?
5 x ? = 30
30 ÷ 5 = 6
∴ the base = 6inches
to check if our answer is correct, we can place these numbers into the formula
A = 
A = 
(30 ÷ 2 = 15)
A = 15

400 miles per hour is a rate. For every hour, the airplane travels four hundred miles.
Knowing this, If the plane travels for three hours, we use a simple multiplication equation to represent this problem.
400 x 3 = 1200
The plane traveled 1200 miles, if it traveled at a speed of four hundred miles for three hours.
