Answer:
3125 gallons
Step-by-step explanation:
16% of the pool water must be chlorine. 16% of the pool water is 500 gallons. To find the total volume of the pool, divide the gallons of chlorine by the percentage chlorine is of the total.
16% = 0.16
500/0.16 = 3125
The total volume of the pool is 3125 gallons.

A submarine is exploring the Pacific Ocean. At 502.5 feet below sea level, the water temperature is 63 1/4 °F. The submarine dives down 115 feet deeper, and the water temperature drops by 2 1/5 °F. What were the elevation and the water temperature after the submarine dove? Assume that sea level is at 0 feet of elevation.
Write an expression to represent the submarine’s elevation after its final dive. Then simplify the expression to find its elevation.
Answer:
-502.5 - 115 = - 617.5
63 1/4 - 2 1/5 =
63 - 2 = 61
1/4 - 1/5 = 5/20 - 4/20 = 1/20
so 63 1/4 - 2 1/5 = 61 1/20
after the sub dove, elevation level is - 617.5 and temp is 61 1/20 F
Step-by-step explanation:
The elevation is 617.5 feet deep and the temperature is [tex]61\dfrac{1}{20}[/tex] F.
What is an expression?Expression in maths is defined as the collection of the numbers variables and functions by using signs like addition, subtraction, multiplication, and division.
The expression for the elevation is,
E = -502.5 - 115
E = - 617.5 feet
The temperature at this elevation is calculated as:-
⇒ 63 ( 1/4 )- 2( 1/5 )
⇒ 63 - 2 = 61
⇒ 1/4 - 1/5
⇒ 5/20 - 4/20
⇒ 1/20
T = 63 (1/4) - 2 ( 1/5 )
T = 61 ( 1/20 ) F
Therefore, the elevation is 617.5 feet deep and the temperature is [tex]61\dfrac{1}{20}[/tex] F.

A rectangle has its diagonal length increased from 5 cm to 25 cm. The new rectangle is similar to the original one. The original perimeter was 14 cm. What is the measure of the new perimeter?
Answer:
The measure of the new perimeter is 70cm.
Step-by-step explanation:
I thought putting up a picture would be easier than explaining it all. The picture is how you would write out the problem.
The original rectangle's measures were 5cm and 14cm. The new rectangles measures are 25 cm and X (We don't know yet.) So write it out. 5cm is to 14cm as 25cm is to X.
5cm/14cm = 25cm/X
Cross multiply. (The arrows I drew. Multiply diagonally.)
You should get
350 = 5X
We need to get X by itself, so divide both sides by 5.
5X/5 leaves X left
350/5 leaves 70
70 = X

Write the number 4 2/3 as an improper fraction.
The improper fraction 14/3.
To convert the mixed number 4 2/3 to an improper fraction, we need to find the equivalent fraction where the whole number and fraction parts are combined.
Step 1: Multiply the whole number (4) by the denominator of the fraction (3):
4 * 3 = 12
Step 2: Add the product from Step 1 to the numerator of the fraction (2):
12 + 2 = 14
Step 3: Write the result from Step 2 as the numerator, keeping the same denominator (3):
The improper fraction is 14/3.
Therefore, the mixed number 4 2/3 can be expressed as the improper fraction 14/3.
To understand the result, imagine dividing a whole into 3 equal parts. With 4 wholes, you have 12 parts (4 * 3 = 12). Adding the 2 extra parts (2/3) gives a total of 14 parts out of 3 wholes, which is represented by the improper fraction 14/3.

Wendy has 10 ½ pounds of potato salad. She wants to divide the potato salad into containers, each of which holds 1 ¼ pounds. How many containers does she need? Show your work and answer in a complete sentence.
Answer:
9 containers
Step-by-step explanation:
Since Wendy wants to divide the 10 [tex]\frac{1}{2}[/tex] pounds of the potato salad into 1 [tex]\frac{1}{4}[/tex] pounds for each container, You just divide 10 [tex]\frac{1}{2}[/tex] by 1 [tex]\frac{1}{4}[/tex] using the following method:
Convert 10 [tex]\frac{1}{2}[/tex] into an improper fraction:
[tex]\frac{21}{2}[/tex]
Convert 1 [tex]\frac{1}{4}[/tex] into an improper fraction:
[tex]\frac{5}{4}[/tex]
Then finally divide [tex]\frac{21}{2}[/tex] by [tex]\frac{5}{4}[/tex] :
[tex]\frac{21}{2}[/tex] ÷ [tex]\frac{5}{4}[/tex]
This is the same as [tex]\frac{21}{2}[/tex] times the reciprocal of [tex]\frac{5}{4}[/tex]:
[tex]\frac{21}{2}[/tex] × [tex]\frac{4}{5}[/tex] = [tex]\frac{42}{5}[/tex] = 8.4
Since we cannot have 8.4 containers, we round it up to 9 containers, because for 8 containers, there will still be some pounds of potato salad left.

Put the following fractions in order from least to greatest, 1/8 2/5, 3/5, 1/6 1/4, 2/3, 1/3

A fraction is a way to describe a part of a whole. The given fractions can be arranged as shown below.
What is a Fraction?A fraction is a way to describe a part of a whole. such as the fraction ¼ can be described as 0.25.
In order to put the following fractions in order from least to greatest, we need to take the LCM of the fraction so that all the fractions have the same denominator.
1/8, 2/5, 3/5, 1/6, 1/4, 2/3, 1/3
Since the LCM of 3, 4, 5, 6, and 8 is 120. Therefore, the fractions can be written as,
1/8 = (1/8) × (15/15) = 15/120
2/5 = (2/5) × (24/24) = 48/120
3/5 = (3/5) × (24/24) = 72/120
1/4 = (1/4) × (30/30) = 30/120
2/3 = (2/3) × (40/40) = 80/120
1/3 = (1/3) × (40/40) = 40/120
Now, the fractions can be arranged as,
15/120 < 30/120 < 40/120 < 48/120 < 72/120 < 80/120
Rewriting the fraction in there original form,
1/8 < 1/4 < 1/3 < 2/5 < 3/5 < 2/3
