Answer:
120 + 20π
Step-by-step explanation:
Find the image of the question attached.
For the square;
Perimeter of a square = 4L
L is the side length of the square
From the diagram, L = 10
Perimeter of a square = 4(10) = 40
Perimeter of 3 squares = 3(40) = 120
For the semicircles:
Perimeter of a semicircle = 2πr/2 = πr
From the diagram;
L = radius of the semicircle = 10
Perimeter of a semicircle = π(10)
Perimeter of a semicircle = 10π
Perimeter of the two semicircles = 2(10π) = 20π
perimeter of the shape = perimeter of 3squares + 2 semicircles
perimeter of the shape = 120 + 20π
Step-by-step explanation:
30/42 = 25/6x-1
180x - 30 = 1050
180x = 1020
x = 5.67
Answer:
Kitchen - 3.89 quarts or 3 quarts of latex enamel
Bathroom - 1.12 quarts or 1 quarts of latex enamel
Step-by-step explanation:
270 feet² for every 3 quartz.
We need how much ft² 1 quart can cover.
So,
270 ÷ 3 = 90 ft²
Every 1 quart covers about 90 ft² of wall.
For kitchen we need to cover 350 ft².
So,
350 ÷ 90 = 3.89 quarts or 3 quarts of latex enamel
For bathroom we need to cover 100 ft².
So,
100 ÷ 90 = 1.12 quarts or 1 quarts of latex enamel
He could add / subtract by the past amount with the next amount to figure out.
22.75-15.80= 6.95
15.80-12.83= 2.97
30.50-12.83= 17.67
30.50-7.02= 23.48
Kind of like that, hope that helps! :)
