Answer:
There are four basic properties of numbers: commutative, associative, distributive, and identity.
Step-by-step explanation:
You should be familiar with each of these. It is especially important to understand these properties once you reach advanced math such as algebra and calculus. Distributive Property.
3 pen + 2 pencil = .47
2 pen + 3 pencil = .38
2(3pen + 2 pencil = .47)
-3(2pen + 3 pencil = .38)
6 pen + 4 pencil = .94
-6 pen - 9 pencil = -1.14
- 5 pencil = -.2
pencil = .04
3pen + 2(.04) = .47
3pen + .08 = .47
3 pen + .08 - .08 = .47 -.08
3 pen = .39
pen = .13
Pen = 13 cents and pencil = 4 cents
Answer:
The answer is C
Step-by-step explanation:
Answer:
Range
Step-by-step explanation:
The difference of the highest and lowest observation is called Range.
Volume of a regular prism=height times area of base
area of base=5
height=1 and 1/2
volume=5 times 1 and 1/2
volume=5+5/2
volume=15/2 aka 7.5 ft^3
