<h2>Ah, volume! </h2>
1) Use the formula of rectangular prism: width x height x length
2) Use the formula of triangular prism: (Base x height x length) ÷ 2
3) Use the formula of cylinder: π x x height
--------------------------------------------------------------------------------------------------
1)
- width = 5 cm
- height = 9 cm
- length = 23 cm
width x height x length
= 5 x 9 x 23
= 1035
<h2>answer: 1035 cubic centimeters</h2>------------------------------------------------------------------------------------------------
2)
- Base = 5 in
- height = 4 in
- length = 20 in
(Base x height x length) ÷ 2
= (5 x 4 x 20) ÷ 2
= 400 ÷ 2
= 200
<h2>answer: 200 cubic inches</h2>------------------------------------------------------------------------------------------------
3)
- radius = 5/2 = 2.5 m
- height = 12 m
π x x height
= π x x 12
= π x 6.25 x 12
= 75π
= 236 (rounded to neareast whole number)

Answer:
240 12.5p + 65
14 p
Step-by-step explanation:
I'll explain the equation in different parts
12.5p - Since the number of times he visits is unknown, it has to be a variable. With each visit, however, he earns 12.5 points.
65 - This is a set value that remains constant
240 - Since he needs AT LEAST 240 points, he needs 240 points or more to get his free ticket
As for solving the equation just use properties of equality
240 12.5p + 65
175 12.5p
14 p
