Answer:
32
Step-by-step explanation:
3 to the 3rd power is 27 and 2 to the 2nd power is 4 so,
27+20 divided by 4
and PEMDAS so exponents, divided then add. 20 divided by 4 is 5. So 27+5 is 32. Hope this helps!

Answer:
1. ![16\ onions](https://tex.z-dn.net/?f=16%5C%20onions)
2. ![4,040.91\ kg](https://tex.z-dn.net/?f=4%2C040.91%5C%20kg)
Step-by-step explanation:
1. You know that the average mass of an onion is 115 grams and Bill needs 4.0 pounds.
Then, since
, we can make the following conversion:
![(4.0\ lb)(\frac{453.592\ g}{1\ lb})=1,814.37\ g](https://tex.z-dn.net/?f=%284.0%5C%20lb%29%28%5Cfrac%7B453.592%5C%20g%7D%7B1%5C%20lb%7D%29%3D1%2C814.37%5C%20g)
Then, the number of onions Bill needs is:
≈ ![16\ onions](https://tex.z-dn.net/?f=16%5C%20onions)
2. Since
, we can make the following conversion:
![(11\ lb)(\frac{1\ kg}{2.20462\ lb})=4.98\ kg](https://tex.z-dn.net/?f=%2811%5C%20lb%29%28%5Cfrac%7B1%5C%20kg%7D%7B2.20462%5C%20lb%7D%29%3D4.98%5C%20kg)
Knowing that all the potatoes sold today at the store bring in $1,420 and 4.98 kilograms of potatoes is $1.75, we can calculate the amount of kilograms the grocery shoppers bought:
![(\$1,420)(\frac{4.98\ kg}{\$1.75})=4,040.91\ kg](https://tex.z-dn.net/?f=%28%5C%241%2C420%29%28%5Cfrac%7B4.98%5C%20kg%7D%7B%5C%241.75%7D%29%3D4%2C040.91%5C%20kg)
This polynomial cannot be factored because it is prime.
