Answer:

Step-by-step explanation:
Given: Four corners of a square chessboard touch the edge of a round table. The length of the chessboard is 1 foot.
To find: length of the radius of the table
Solution:
Diameter of the round table is equal to the diagonal of a square chessboard.
Diagonal of a square chessboard =
× side of the square chessboard
Here, side of a square chessboard = 1 foot
So,
Diagonal of a square chessboard =
× 1 =
foot
Diameter of the round table = Diagonal of a square chessboard =
foot
Radius of the round table = Diameter of the round table/2
= 
Answer:
x=−4.350480,−1.669843,7.020324
Step-by-step explanation:
Step 1: Multiply both sides by -x+5.
−x3+x2+34x+56=−x+5
−x3+x2+34x+56−(−x+5)=−x+5−(−x+5)(Subtract -x+5 from both sides)
−x3+x2+35x+51=0
(Use cubic formula)
x=−4.35048,−1.669844,7.020324
Check answers. (Plug them in to make sure they work.)
x=7.020324(Works in original equation)
x=−4.35048(Works in original equation)
x=−1.669844(Works in original equation)
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!
