A percent is how many out of 100.
13/20 is how many out of 100?
You multiply the top and bottom by 5, as 5x20 is 100
13x5 is 65
Therefore, 65 out of every hundred cans, or 65%, are recycled

Step-by-step explanation:
<h3>Given AP </h3>
<h3>To find</h3>
<h3>Solution</h3>
- a₁₂ = a + 11d = 62
- a₂₀ = a + 19d = 102
<u>Subtract the first equation from the second one:</u>
<u>Find a:</u>
- a + 11*5 = 62
- a = 62 - 55
- a = 7
<u>Find the sum of the first 20 terms:</u>
- S₂₀ = 1/2*20(a + a₂₀) = 10(7 + 102) = 10(109)= 1090
Answer:
128 ft³
Step-by-step explanation:
Volume of a prism is the area of the base times the height:
V = Ah
In the case of a triangular prism:
V = (1/2 bh) (L)
Given b = 8 ft, h = 4 ft, and L = 8 ft:
V = 1/2 (8 ft) (4 ft) (8 ft)
V = 128 ft³
