A candle is in the shape of a square prism. The candle is 16 meters high, and its volume is 960 cubic meters. Find the length of
madam [21]

Answer:

The length of each side of the square base is 2\sqrt{15}\ m

Step-by-step explanation:

we know that

The volume of a square prism is equal to

V=b^{2}h

where

B is the length side of the square base

h is the height of the prism

we have

V=960\ m^{3}

h=16\ m

substitute and solve for b

960=b^{2}16

b^{2}=960/16

b=\sqrt{60}\ m

Simplify

b=2\sqrt{15}\ m

Amanda plans on going to the amusement park this Friday. It costs $25.00 to
Vera_Pavlovna [14]

Answer:

$36.25

Step-by-step explanation:

To enter the park, Amanda pays 25 dollars.

+$25

It costs 1.25 for every ride that Amanda goes on.

Since we don't know the number of rides Amanda goes on, we will add a variable to represent the number of rides.

1.25x

Then, the passage says that Amanda goes on 9 rides. So, substitute 9 for x.

Equation: 25+1.25(9)

Then solve:

$36.25
