Answer: 4 gallons will be needed.
Step-by-step explanation:
The bottom of the pool is rectangular in shape. The formula for determining the area of a rectangle is expressed as
Area = Length × width
Olympic-sized swimming pool of uniform depth measures 50 meters by 21 meters. The area of the bottom would be
Area = 50 × 21 = 1050 m²
The bottom of the pool is to be treated with a sealer, and one gallon of the sealer covers 300 square feet of surface. This means that the number of gallons of sealer required for the job would be
1050/300 = 3.5gallons Approximately 4 gallons to the nearest gallon
Answer:
9.4
Step-by-step explanation:
How to find the mean of a data set: Add each number in the set together. Then divide the sum of all of the numbers by how many numbers there are.
1298 - 4x =171 + 3x
Add 4x to both sides
1298 = 171 + 7x
Subtract 171 from both sides
1127 = 7x
Divide by 7 on both sides
x = 161
They will both say the number 161 at the same time.
Answer:
n = -56
Step-by-step explanation:
first subtract the 24 from both sides. you get -14.
then multiply 4 to -14.
you get -56
Discrete data is the answer
