A pyramid \rm frustum has a 4 m by 4 m square top

Height = 12 m

Base = 20 m

The volume of a square pyramid with a  \rm frustum is given by

V = (1/2) * ( Area of base + Area of  \rm frustum ) * height of the  \rm frustum from the base

V = 0.5 * ( 20 *20 + 4*4 ) * 12

Is there are 4 more girls than boys in ms. Raubs class of 28 students what is the ratio of girls to boys
Viefleur [7K]
The ratio of girls to boys would be  16:12 because if you divide 28 by 2 you get 14. subtract 2 to on one of them and add the two to the other. You get 12 and 16. There is a difference of 4 to them and when you add them together you get 28. :)

A bouncing ball reaches a height of 54 inches at its first peak, 36 inches at its second peak, and 24 inches at its third peak.
marin [14]
36/54=2/3
36/24=2/3

so each time it bounches 2/3 or what it bounced before

seems to be a geometric sequence
an=a1r^(n-1)
a1=first term
r=common ratio
a1=54
common ratio is 2/3
an=54(2/3)^(n-1)

Answer:

The formula to find the perimeter of a rectangle is 2L + 2W.

Here L=5 and W=2; hence:

2*5+2*2

=14

The perimeter is 14.

The formula to find the area of a rectangle is length × width; hence:

5*2=10

The area of the rectangle is 10.
