Amy has $8 less than Maria.Together they have $30
gtnhenbr [62]
 a + m = 30
a = m - 8

(m - 8) + m = 30
2m - 8 = 30
2m = 30 + 8
2m = 38
m = 38/2
m = 19

a = m - 8
a = 19 - 8
a = 11

so Amy has $11 and Maria has $ 19

IN NEED OF A MATH WIZ!!!!!
densk [106]
The unoccupied volume will be the volume of the can minus the volume of the three tennis balls.

V=HπR^2-3(4πr^3)/3

V=HπR^2-4πr^3  where H=height of can, R=radius of can, r=radius of ball

We are told H=7, R=1.5, and r=1.125  (2.25/2=d/2=r) so

V=7π1.5^2-4π1.125^3

V=15.75π-5.6953125π  in^3

V≈31.58 in^3

Hello!

You put the numbers in for x

3/5^-2 = 2.777
3/5^-1 = 1.667
3/5^0 = 1
3/5^1 = 0.6
3/5^2 = 0.36

The points are (-2, 2.777), (-1, 1.667), (0, 1), (1, 0.6), (2, 0.36)

Answer:

94.88 cubic units

Step-by-step explanation:

Volume of the prism = Area of base * Height

= 5( \frac{1}{2}  \times 2.75 \times 4) \times 3.45 \\  \\  = 5 \times 2.75 \times 2 \times 3.45 \\  \\  = 10\times 2.75  \times 3.45 \\  \\  = 94.875 \\  \\   \approx 94.88 \: cubic \: units
