Alonzo is staining the wooden floor of a court. The court is in the shape of a rectangle. Its length is 54 feet and its width is 30 feet. Suppose each can of wood stain covers 135 square feet. How many cans will he need to cover the court?
The area of the court is length × width = 54 ft × 30 ft = 1620 ft².
Thus, Alonzo will need 1620 ft² ÷ 135 ft²/can = <<1620/135=12>>12 cans of wood stain. Answer: \boxed{12}.
To find out how many cans of wood stain Alonzo will need to cover the court, we need to calculate the total area of the court and divide it by the coverage area of each can of wood stain.
Step 1: Calculate the area of the court.
The area of a rectangle is calculated by multiplying the length by the width.
Area = length × width
Area = 54 feet × 30 feet
Area = 1620 square feet
Step 2: Determine the coverage area of each can of wood stain.
The coverage area of each can is given as 135 square feet.
Step 3: Divide the total area of the court by the coverage area of each can.
Number of cans = (Total area of court) ÷ (Coverage area of each can)
Number of cans = 1620 square feet ÷ 135 square feet
Number of cans = 12 cans
Therefore, Alonzo will need 12 cans of wood stain to cover the court.
To find out how many cans Alonzo will need, we need to calculate the area of the court and then divide it by the area one can of wood stain can cover.
Step 1: Calculate the area of the court
Area = Length x Width
Area = 54 feet x 30 feet
Area = 1620 square feet
Step 2: Divide the area of the court by the area one can of wood stain can cover
Number of cans needed = Area of court / Area one can covers
Number of cans needed = 1620 square feet / 135 square feet
Step 3: Perform the division to find the number of cans needed
Number of cans needed = 12
Thus, Alonzo will need 12 cans of wood stain to cover the court.
Jenny wants to buy new carpet for her living room floor. The floor is in the shape of a rectangle. Its length is 17 feet and its width is 13 feet. Suppose carpet costs 11 for each square foot. How much will carpet cost for the floor?
To calculate the cost of the carpet for the floor, we need to find the area of the floor and multiply it by the cost per square foot.
Step 1: Calculate the area of the floor.
The area of a rectangle is calculated by multiplying the length by the width.
Area = length × width
Area = 17 feet × 13 feet
Area = 221 square feet
Step 2: Multiply the area of the floor by the cost per square foot.
Cost = Area × cost per square foot
Cost = 221 square feet × $11/square foot
Step 3: Perform the multiplication to find the total cost.
Cost = $2,431.
Therefore, the carpet will cost $2,431 for the floor.
magician has rabbits. Each rabbit weighs the same. The combined weight of all the rabbits is 7.2 kilograms.
(a)Let w be the weight of each rabbit (in kilograms). Write an equation that can be used to find w. First choose an appropriate form. Then fill in the blanks with the letter w and the numbers 6 and 7.2.
Since each rabbit weighs the same, we can represent the weight of each rabbit as w (in kilograms).
The combined weight of all the rabbits is 7.2 kilograms.
The equation that can be used to find w is:
Number of rabbits (n) × Weight of each rabbit (w) = Combined weight of all rabbits
In this case, the number of rabbits (n) is not given. Let's use the information given in the problem to determine the number of rabbits first:
Weight of each rabbit (w) = 6 kg
Combined weight of all rabbits = 7.2 kg
Using the equation above, we can write:
n × 6 kg = 7.2 kg
So, the equation that can be used to find w is:
6n = 7.2
or
6 * n = 7.2
