Answer: About 12 of those 60 students are boys.
To find the percent, you'll convert 20% to a decimal.
20 / 100 = 0.2
Then, multiply 60 by 0.2
0.2 × 20 = 12
That's one way, another way is:
Convert 20% to a fraction.
20% = 1/5
Then multiply 60 by 1/5.
60 × 1/5 = 60/5
Lastly, divide 60 by 5
60 / 5 = 12.
Hence, 12 is the answer.

Step-by-step explanation:
the length of the box is represented by (8m2)
does that mean 8m^2?
in English that would be 8 times m^2 or 8 * m * m.
if that is true, then the volume of the box would be equal to (8*m^2)^3 which is equal to 8^3 * m^6 which is then simplified further to 512 * m^6 which can also be written as 512m^6.
if we assume that m is 3, then the side of the box is equal to 8 * 9 which is equal to 72 and that is cubed to get 373248.
working that out algebraically, it would look like this:
(8*3^2)^3 equals 8^3 * (3^2)^3 which is equal to 8^3 * 3^6 which is equal to 512 * 729 which is equal to 373248
Zach has 399 marbles because 21*19 is equal to 399.
Answer:
volume from geometri always:
base area × h
if have peak point always:
1/3 × base area × h
the base of the pyramid in the figure is rectangle. then base from rect. is:
l × w
= 9 × 7
= 63
let get into formula: (use the second formula because pyramid has a peak point)
=1/3 × ba × h
=1/3 × 63 × 7
=21 × 7
=147 yd³
