*see attachment for the diagram of the wall
Answer:
6 cans
Step-by-step explanation:
First, let's calculate the area of the wall to be painted = area of a rectangle
Area of the rectangle = length*width
From the diagram,
Length = 13 ft
Width = 10 ft
Area = 13*10 = 130 ft²
Given that 1 can of paint covers 25 ft²,
Number of can of paints that will cover 130 ft² = 130/25 = 5.2
This means we will need more than 5 cans. So Joan will need to get roughly 6 cams of blackboard paint.
Answer: $2,185
to find the amount the business paid in taxes, you have to find 9.5% of $23000
9.5% is 0.095 as a decimal
multiply 23000 by 0.095 to get 2185
therefore, the business paid $2,185 in taxes last year
hope this helps!
10, because 10 does not need to be rounded to the nearest 10 if the number is already 10, but if the number was 17 then rounding to the nearest 10 would be 20
Answer: 49.13 ft^2
Step-by-step explanation:
Triangle: A=6*8/2=24 ft^2.
Circle: A=πr^2=16π≈50.265, 50.265/2≈25.13 ft^2.
24+25.13=49.13 ft^2
Hello from MrBillDoesMath!
Answer:
8
Discussion:
Let the number be "n". Then the question states that
3n - 15 = (n/2) + 5 => multiply both sides by 2
6n - 30 = n + 10 => subtract n from both sides
5n - 30 = 10 => add 30 to both sides
5n = 30 + 10 = 40 => divide both sides by 5
n = 40/5 = 8
Thank you,
