Answer:

1.5

Paha777 [63]

Answer:

640 ft^3

Step-by-step explanation:

In this case we must divide the area into two parts, in the prism and in the pyramid, the sum of the volume of these parts would be the total volume

However

for the volume of the prism it would be the multiplication of the three sides, that is:

8 * 8 * 9 = 576

i.e. 576 ft ^ 3

For the pyramid, the formula is the multiplication of the area of the base by the height divided by 3, we know that the area of the base is 8 * 8 and that the height is 3, therefore:

8 * 8 * 3/3 = 64

64 ft ^ 3 is the volume of the pyramid

The total would be:

576 + 64 = 640

Total volume would be 640 ft ^ 3

I need help solving the second part. Give me help or answer.
alex41 [277]

I think the answer is 273

You divide 31% by any of the other percentages (like for example, 25%) and then divide 93 by whatever you got as your answer (31 divided by 25 was 1.24, so I divided 93 by 1.24 to get 75) then repeat that with the other percentages and add them all up.

One patterned blue fabric sells for $15.00 every two yards, and another sells for $37.50 every 5 yards. Do these fabrics have th
Svetradugi [14.3K]
All we need to do is to find out how much is worth one yard in both fabrics, so we divide $15.00 by 2 and $37.50 by 5:

$15.00 ÷ 2 = $7.50 per yard
$37.50 ÷ 5 = $7.50 per yard

As both prices per yard are the same, the answer is: <u>Yes, these fabrics have the same unit cost.</u>
