Commutative property of addition is being used.

This means that you can switch around where the numbers are and still get the same answer.

Hope this helps!

This is the formula for the volume of a right square pyramid, where a is the side length of the base and h is the height: . Whic
Lesechka [4]

Answer:

C. h=3V/a^2 is the correct answer

Step-by-step explanation:

Given:

V=1/3a^2h

It can be rewritten as

V=1/3 *( a^2) * h

Divide both sides by (1/3)*h

V / (1/3*h) = (1/3)* (a^2) * h / (1/3)*h

V÷1/3*h = a^2

V÷3/1*h=a^2

3V/h=a^2

Multiply both sides by h

3V/h*h=h*a^2

3V=h*a^2

h=3V/a^2

C. h=3V/a^2 is the correct answer

The spinner shown is divided into congruent sections that are labeled 1-6. If the spinner is spun twice, what is the probability
slava [35]

Answer:

1/36

Step-by-step explanation:

This is a simple use of the multiplication rule of probability, which is:

"<em>The probability that Events A and B both occur is equal to the probability that Event A occurs times the probability that Event B occurs, given that A has occurred</em>"

Using this rule, we square 1/6 to get 1/36. In other forms:

Decimal:0.02777777777(Round to whatever decimal place you need)

Percentage: 2.778%(I don't see you needing any more places)

Hope my answer helped you!
