The width of the Ochoa Community Pool is 20 feet . The length is twice as long as its width. What is the perimeter of the pool?

Answers

Answer 1
Answer:

Answer:

The perimeter of the pool is 120 feet.

Step-by-step explanation:

width of the Ochoa community pool  = 20 feet  

length is twice as long as its width = 2(20) = 40 feet  

Use this formula to get perimeter = 2(w) + 2(L)

then the perimeter equals to  = 2(20)+ 2(40)

= 40 + 80 = 120 feet

The perimeter of the pool is 120 feet.
Answer 2
Answer: the width is 20 feet the length is 20 feet x 2 = 40 and I bet you know how to work out the perimeter add all the width and length so 20 + 20 +40 + 40 =120 120 feet is the answer your welcome

4 glue sticks cost $7.76

Which equation would help determine the cost of 13 glue sticks?

Answers

Answer:

y=1.94x

13 glue sticks cost $25.22.

Step-by-step explanation:

4 blue sticks cost $7.76, this means that one glue stick costs

$7.76/4 = $1.94.

Let y be the cost of the glue sticks, and x be the number of glue sticks; then

\boxed{y=1.94x}

We can use this equation to find the cost of 13 glue sticks; we just put x=13\ into our equation and it gives:

y=1.94(13)=25.22

So 13 glue sticks cost $25.22.

What is 65% written as a fraction in simpliest form.

Answers

Any number expressed as a percentage may be written as: number / 100. In this case, this becomes 65/100. In order to simplify this fraction, we take the highest common factor of the numerator and denominator, which works out to be 5. The fraction then becomes 13/20
I hope that my answer is helpful! Let me know if you need something more :)

65% written as a fraction in simplest form is 13/20.

To express 65% as a fraction in its simplest form, you need to convert the percentage to a fraction with a denominator of 100 (since percentage means "per 100").

Divide the percentage value by 100:

65% = 65/100

Now, to simplify the fraction, find the greatest common divisor (GCD) of the numerator and denominator and then divide both by the GCD to get the simplest form:

The greatest common divisor of 65 and 100 is 5.

Divide both the numerator and denominator by 5:

(65 ÷ 5) / (100 ÷ 5)

= 13/20

So, 65% written as a fraction in simplestform is 13/20.

Hillary used 5 L of a cleaning solution to scrub down 25 M^2 of table tops in the school cafeteria. how many litres of cleaning solution are required to clean a surface with an area of 65 m^2 if this solution is directly proportional?A.10L
B.13L
C.15L
D.25L

Answers

Answer is B) 13L.

Explanation:

We can calculate the number of liters of cleaning solution required to clean up a surface with the given area by simple method of proportion.

If 25m^2 area requires 5L of cleaning solution,

then let x bethe number of liters required for cleaning a 65m^2 area.

We can write it as:

25 / 65 = 5 /x

x = (5 x 65) / 25 = 325/25 = 13

So, 13 litres of cleaning solution is required to clean a surface with 65m^2 area.

Sybrina jogged 2 miles in 30 minutes. At this rate, how far would she jog in 90 minutes?At what rate did she jog each hour?

Answers

6 miles in 90 minutes and 4 miles per hour. 30 times two is 60 min so 2 miles times two is 4 miles. 

another 30 min is 90 min and another two miles is 6 miles.
2miles per 30min - 2 to 3
90/30=3x2=6
