Answer 1

36 oz

i dont know how to explain i just know

Answer 2

20.25 ounces

Explanation:

We are given 2.25 ounces of cranberry poured into the container per second. We need to find is how much that is after 9 seconds. (Note: This is different from the 15.75 ounces of orange.) There are many ways to solve this question (e.g If 2.25 is 1, then multiply 2.25 and 9 = 20.25) Now to solve this let's set up fractions; let "x" be the variable;

`(1)/(2.25)=(9)/(x)`

Apply fraction: if
`(a)/(b)=(c)/(d)\mathrm` then
`a\cdot \:d=b\cdot \:c` (meaning cross multiply)

`1\cdot \:x=2.25\cdot \:9`

Simplify

• Multiply by 1

`1 x = 2 . 2 5 \cdot 9 \\\\ x = 2 . 2 5 \cdot 9`

• Multiply the numbers

`x = 2 . 2 5 \cdot 9\\\\x=20.25`

Therefore, there are 20.25 ounces of fruit pouch in the container after 9 seconds.
