If the perimeter is 98 cm, the sum of the lengths of two adjacent sides is 49 cm.

... (2x -1) + (3x +5) = 49 . . . . use the given information and relation

... 5x +4 = 49 . .  . . . . . . . . . simplify

... 5x = 45 . . . . . . . . . . . . . . . subtract 4

... x = 9 . . . . . . . . . . . . . . . . . divide by 5

The left side dimension is then

... 2x -1 = 2·9 -1 = 17 . . . . cm

The top dimension is

... 3x +5 = 3·9 +5 = 32 . . . . cm

The rectangle is 17 cm by 32 cm.

Must include explanation !!
stich3 [128]

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!
