Answer:
he got 8 books free and now has 24 books total
Step-by-step explanation:
16/2=8
that would be the answer for how many books he got for free because if there is a box of 16 books and for every2 books you get one free then you would divide 16 and 2 and get 8 then
16+8=24
add the number of books he got for free with the original 16 books he already had and get 24 total books.
The individual-size box of cereal is a rectangular prism with a volume of 44.625 inches³.
<h3>What is the volume of a rectangular prism?</h3>
The volume of rectangular prism of length l, width w and height h is given by:
V = lwh.
In this problem, the standard dimensions are:
- l = 3(1/2) = 3 + 0.5 = 3.5 inches.
- w = 8(1/2) = 8 + 0.5 = 8.5 inches.
The individual-size box has a 1/10 of the volume of the original box, hence:
V = 0.1 x 3.5 x 8.5 x 15 = 44.625 inches³.

Using the together rate, it is found that the time it would take the second pump, working alone, to fill the tank is:
B. 90 minutes
The <em>together rate</em> is the <u>sum of each separate rate</u>.
In this problem:
- The together rate is of 1/60.
- The first rate is of 1/150.
- The second rate is of 1/x.
Then:
Applying cross multiplication:
Hence, it would take 90 minutes for the second pump, working alone, to fill the tank.

Answer:
percentage decrease is 70%
Step-by-step explanation:
To find percentage decrease of 2 quantities, we have to find the difference of the quantities and divide by the original quanity. Then we multiply by 100 to find the PERCENTAGE.
We will use formula:
Where
"New" is the latest quantity
"Old" is the first (previous) quantity
Here, New = 5.3 & Old = 17.71
We substitute into formula and find:
So we can say that the percentage decrease is 70%
