Matt could do one of the following arrangements;
2 rows of 8 CDs
4 rows of 4 CDs
Facts:
- tub has 1400 gallons
- draining at 27 gallons/minute
How much water will be left after 18 minutes?
We know that after 1 minute, there will be 27 gallons less.
So after 18 minutes, there must be 18 times less water.
27 x 18 = 486
This is how much water was lost in 18 min
So to find out how much he had left after <u>486 is subtracted.</u>
Therefore, the answer is A) -486 gallons
The width of the rectangular pen is equal to 14 feet.
Answer:
The answer is 2 1/6
Step-by-step explanation:
First you would divide 13 by six and that would leave you with 2 with a remainder of 1. Then you would put together the fraction leaving 6 as the denominator, 2 as the whole number, and 1 as the numerator.
Let me know if you need any other help!
Answer:
13 in
Step-by-step explanation:
let w be width then length is w + 6
the area (A) of a rectangle is calculated as
A = length × width , then
A = w(w + 6) = 91 , that is
w² + 6w = 91 ( subtract 91 from both sides )
w² + 6w - 91 = 0 ← in standard quadratic form
(w + 13)(w - 7) = 0 ← in factored form
equate each factor to zero and solve for w
w + 13 = 0 ⇒ w = - 13
w - 7 = 0 ⇒ w = 7
however, w > 0 then w = 7
and length = w + 6 = 7 + 6 = 13 in
