Answer:
100
Step-by-step explanation:
Hello! to calculate the number of tiles needed for the floor you need two things
1. number of tiles that fit across the width, this is achieved by dividing the total width by the width of each tile
Width=20ft=240in

2.number of tiles that fit in the logitude, this is achieved by dividing the total length by the length of each tile.
leght=30ft=360in

Finally, you multiply the number of tiles that fit in width by the number of tiles that fit in length.
N=10X10=100

Step-by-step explanation:
If the kilowatt-hours stay proportional to the total bill, then you are using more electricity. If the bill goes up a lot more than the kilowatt-hours, then you are on some sort of "rate plan" that punishes peak usage
Answer:
166.72
Step-by-step explanation:
A= 2(wl+hl+hw)
A= 2(3.2×8.5+4.8×8.5+4.8×3.2)
A= 2(27.2+40.8+15.36)
A= 2(83.36)
A= 2×83.36
A= 166.72
We want to divide 1/2 pound in 8 equal parts
1/2 dividend by 8/1 is the same as
1/2 multiplied by 1/8 =1•1/2•8=1/16
Each package will weigh 1/16 of a pound
Or 1 ounce since 1 pound = 16 oz
Answer:
C. 8
Explanation:
One way to solve this is to find 30% of each class, 28 and 24.
30% of 28:
28 • 0.30 = 8.4
30% of 24:
24 • 0.30 = 7.2
You can then find the average of these two numbers.
8.4 + 7.2 = 15.6
15.6 ➗ 2 = 7.8
7.8 rounds up to 8
Another way to solve is to first find the average number of people in each class.
28 + 24 = 52
52 ➗ 2 = 26
You can then find 30% of this number.
26 • 0.30 = 7.8
7.8 rounds up to 8
