Answer:
Step-by-step explanation:
L=3S
In 5 years,
L+5=2(S+5)
L+5=2S+10
L=2S+5
Substituting from above,
3S=2S+5
S=5
So then,
L=3(5)
L=15
Answer:
18.2 feet^3 of water
Step-by-step explanation:
First let's find 80% of the full capacity, which is 24. To do that, multiply 24 x 0.8, which is 19.2.
Now how much space to the fish take up? There are 8 fish, and each one takes up 1.5 cubic INCHES. 8 x 1.5 = 12 cubic inches, but we need cubic feet. Luckily, there are 12 inches in 1 foot so it'll be a clean and simple 1 foot. The "cubic" part only shows that we're measuring volume.
The 80% capacity - fish capacity = how much water is needed. That will be 19.2 - 1 = 18.2
That's it! Hopefully this helped!
Answer: 12.32%
Step-by-step explanation:
1. 
is the original long side and 
is the original short side.
2. The area of the original rectangle is 
.
3. The rectangle is extended 4% on the long sides and 8% on the short sides. therefore, the new long side is:
4. And the new short side is:
5. The new area is:
6. The percentage of increase is calculated by substracting the new area and the original area:
7. The result is:
(0.1232)(100)=12.32%
