In the library at Lenape Elementary School, there are

Phoenix [80]

Solution:

we are given that

In the library at Lenape Elementary School, there are 3/8 as many fiction books as there are nonfiction books.

There are 44 books in the school library.

we have been asked to find How many books are fiction books?

Let there are x non fiction books in the library. Then there will be $\frac{3}{8}x$ fiction books.

Hence we can write

$x+\frac{3}{8}x=44\\\\\text{Now solve for x}\\\\\frac{8x+3x}{8}=44\\\\\frac{11x}{8}=44\\\\11x=44*8\\\\x=\frac{44*8}{11}\\\\x=4*8=32\\$

Hence there are 32 non-fiction books in the library.

and 44-32=12 fiction books in the library.

An element with a mass 310 grams decays by 5.7% per minute. How much of the element is remaining after 9 minutes, to the nearest

balu736 [363]

Mass of an element = 310 grams

Percentage of the element that will decay in a minute = 5.7%

Quantity of the element that will decay in one minute :

$= \frac{5.7 \times 310}{100}$

$= \frac{1767}{100}$

$= \tt17.67 \: grams$

Thus, 17.67 grams of the element will decay every minute.

Quantity of element that will decay after nine minutes :

$= 17.67 \times 9$

$=\tt 159.03 \: grams$

Thus, 159.03 grams of the element will decay after 9 minutes.

Quantity of element that will remain after 9 minutes :

$= 310 - 159.03$

$= \tt150.97 \: grams$

Thus, 150.97 grams of the element will remain after nine minutes.

We can round off 150.97 to 151.00.

Therefore, 151.00 grams of the element will remain after 9 minutes.
