The area of a square deck is 81 square feet. How long is each side

Answers

Answer 1
Answer: The formula for the area of a square is:

A=s²

Since we known that the area is 81ft², we can solve for the length of a side.

A=s²
81=s²
find the square root of both sides
9ft=s

The length of each side is 9ft
Answer 2
Answer: All you need to do is find the square root of 81, because the formula for the area of square is s^(2).

The square root of 81 is 9 ( 9 x 9 = 81)
To double check, plug 9 into the formula.
area = s^(2)
area = 9^(2)
area = 81

So, therefore, each side is 9ft.

Christian has a large rectangular container that is 30 inches by 20 inches by 20 inches. He also has a small cubical container with each side 10 inches. If he fills up the small container with water and pours into the large container, the water reaches to how many inches?

Answers

find volumes
V=LWH
large is
30*20*20=V=12000 in^3

small is 10 by 10 by 10
V=10*10*10
V=1000

how many times of smaller=larger
hw many times 1000=12000
divide both sides by 1000
how many times =12


answer is 12 times


A triangle has side lengths of (1.9x + 6.2y) centimeters, (2.5x + 8.3w) centimeters, and (1.6w - 5.1y) centimeters.PART A:

Write an expression that represents the perimeter, in centimeters, of the triangle.

Show all work.



PART B:

Write an equivalent expression to represent the perimeter from PART A. by factoring out the greatest common factor.

Show all work.


IF ANSWER BOTH I WILL GIVE BRAINIEST

Answers

Answer:

Step-by-step explanation:

Part A : Since sides of triangle are ( 1.9x + 6.2y )cm

(2.5x + 8.3w)cm and (1.6w - 5.1y)cm.

Now perimeter of a triangle = sum of all sides length

Perimeter = (1.9x + 6.2y) + (2.5x + 8.3w) + (1.6w - 5.1y)

                = (1.9x + 2.5x) + (6.2y - 5.1y) + (8.3w + 1.6w)

[ collecting the like terms together ]

Perimeter = 4.4x + 1.1y + 9.9w

Part B : Now we factorize the term for perimeter given in part A.

Perimeter = 1.1 (4x + y + 9w)

So equivalent factor will be (1.1 (4x + y + 9w).

Answer:

see explanation

Step-by-step explanation:

A

The perimeter is the sum of the 3 sides, thus summing the 3 sides

1.9x + 6.2y + 2.5x + 8.3w + 1.6w - 5.1y ← combine like terms

= 4.4x + 1.1y + 9.9w ← expression for perimeter

B

Factor out 1.1 from each term, thus

4.4x + 1.1y + 9.9w

= 1.1(4x + y + 9w) ← perimeter in factored form
