Answer:

The length of one side of the rectangle is 99 centimeters.

Step-by-step explanation:

The reason the length is 99 centimeters is because if the total length is 376, and one width side is 89, you can use the equation (2(89)+2x=376)/2 to find the length.

You have an above ground pool that is 20 feet in diameter. One bag of sand does three square feet. How many bags of sand do you

r-ruslan [8.4K]

Answer: Number of sand bags are 105

Step-by-step explanation:

Alright, lets get started.

The diameter of pool is given as : $20 \ \text{feet}$

The radius of pool will be : $r=\frac{20}{2}=10$

So the area of the pool will be:

Area = $\pi r^2$

Area = $\pi *10^2$

Area = $100 \pi$

Area = $314.16$

3 square feet is covered by 1 sand bag, so

314.16 square feet will be covered by : $\frac{314.16}{3}$

So, no of sand bag = $104.7$

Rounding off to nearest number

Number of sand bags are 105 : Answer

Hope it will help :)

solve the following pair of linear equation 2x+3y=5 , 7x-5y=2 has a unique solution if yes find the solution

slava [35]

Answer:

(1, 1 )

Step-by-step explanation:

Given the 2 equations

2x + 3y = 5 → (1)

7x - 5y = 2 → (2)

Multiplying (1) by 5 and (2) by 3 and adding will eliminate the y- term

10x + 15y = 25 → (3)

21x - 15y = 6 → (4)

Add (3) and (4) term by term to eliminate y

31x = 31 ( divide both sides by 31 )

x = 1

Substitute x = 1 into either of the 2 equations and evaluate for y

Substituting into (1)

2(1) + 3y = 5

2 + 3y = 5 ( subtract 2 from both sides )

3y = 3 ( divide both sides by 3 )

y = 1

Solution is (1, 1 )
