Answer:

20 quarters ($5) and 10 nickels ($0.50)

Step-by-step explanation:

Q+ N = 30

Q = 30-N

0.5N + 0.25(30-N) = 5.50

0.5N + 7.50-0.25N = 5.50

-0.20N = -2

N=10 Q=30-N Q=30-10 Q=20

10*0.5 = 0.50

20*0.25 = 5

5 + 0.5 = $5.50

Pyramid A is a right square pyramid with a height of 100 m and a square base with a perimeter of 356 m. Pyramid B has a square b

Tomtit [17]

Answer:

The volume of pyramid B is 3.5 times greater than the volume of pyramid A

Step-by-step explanation:

The area of squared based a pyramid is given by:

$Area = \frac{1}{3}*s*s*h$

Where 's' the length of the side of the base and 'h' is the height.

For pyramid A:

h= 100 m

s= 356/4 = 89 m

$Area_A = \frac{1}{3}*89*89*100\\Area_A=264,033.33\ m^3$

For pyramid B:

h= 215 m

s= 456/4 = 114 m

$Area_B = \frac{1}{3}*114*114*215\\Area_B=931,380\ m^3$

Pyramid B has a greater volume and the ratio between volumes is:

$\frac{Area_B}{Area_A} =\frac{931,380}{264,033.33}\\\frac{Area_B}{Area_A} =3.5$
