Answer: Density = 0.23 tons per cubic meter.
Step-by-step explanation:
Formula : 
1 ton = 32000 ounces
⇒ 1 ounce = 0.00003125 ton
⇒ 7 ounces = 7(0.00003125)= 0.00021875 ton
1 gallon = 0.00378541 cubic meter
2.5 gallons = 0.009475 cubic meter
Density= 
Hence, Density = 0.23 tons per cubic meter.
As order is not important in this problem, we make use of the concept of Combination. A group of 5 people should be picked out of the 8. In mathematical notation, the possible combinations (P) is 8C5. This is equal to 56. Thus, there are 56 different ways to which 5 people can be selected.

Answer:
5 units
Step-by-step explanation:
Calculate the length using the distance formula
d = √ (x₂ - x₁ )² + (y₂ - y₁ )²
with (x₁, y₁ ) = B(- 3, - 2) and (x₂, y₂ ) = C(0, 2)
AB =
