Explain the difference between the slant height of a pyramid and the height of the pyramid.

Answers

See the diagram below.
$h$ is the height, and $s$ is the slant height.

The height is the distance from the base of the pyramid to the vertex (the top of the pyramid). It runs perpendicular to the base.

The slant height is the distance from the base of the triangles which make up its sides to the vertex. It runs perpendicular to this base as well.

A jump suit costs 125 dollars.The rate of the discount is 20 percent.What is the discount

Answers

10% of $125 is $12.50.

Now 20%=2*10%.

So 20% of $125 is $25.

If you were to receive a 20% discount, you'd only have to pay $100 to bag the jump suit.

a $25 discount is what the discount is.

How do you get the answer for 820 decreased by 25%

Answers

So in this one, we are DECREASING by 25%, so we say 25% of 820...

25% × 820 =
.25 × 820 = 205

Now since we are decreasing by 25%, we take our answer and subtract it from the original amount, 820.

820 - 205 = 615

820 decreased by 25% is
615.

beyonce michelle and kelly shared a carton of soft drink containing 2 dozen cans. Beyonce takes 3/8 Michelle takes 5/12 and kelly takes 5./24/ How many cans does each person receive?

Answers

Beyonce gets 9 cans worth, Michelle drinks 10 cans worth of soft drink and kelly receives 5 cans worth.

Dozen = 12 so 2 dozens = 12x2=24

3/8 = 9/24 because 8x3=24 & 3x3=9
5/12 =10/24 because 12x2=24 & 5x2=10
5/24 is fine because it is already out of 24
