Answer:
4 bags
Step-by-step explanation:
Step 1
1 bag = 24 oz
Hence:
1 ounce(oz) = 0.0625 pound
24 oz = x pound
Cross Multiply
x pound = 24 × 0.0625 pound
x pound = 1.5 pounds
Hence, 1 bag = 1.5 pounds
Step 2
If
1.5 pounds = 1 bag
5 pounds = x bags
Cross Multiply
1.5 x = 5 × 1
x = 5/1.5
x = 3.33 bags
At least 5 bags means exactly 5 bags or more
= 3 bags = 1.5 × 3 = 4.5 pounds
4 bags = 1.5 × 4 = 6 pounds
Therefore, he will need to buy 4 bags
at least 5 pounds

Answer:
A. Approximately 2000 times the mass of an electron.
Step-by-step explanation:
Lets do the division:
Mass of neutron / mass of electron
2 × 10^-24 / 9 x 10^-28
= 0.222 x (10^(-24 - (-28))
= 0.2222... x 10^4
= 2222.
