It takes 8 minutes for Byron to fill the kiddie pool in the backyard using only a handheld hose. When his younger sister is impatient, Byron also uses the lawn sprinkler to add water to the pool so it is filled more quickly. If the hose and sprinkler are used together, it takes 5 minutes to fill the pool. Which equation can be used to determine r, the rate in parts per minute, at which the lawn sprinkler would fill the pool if used alone?

Answers

Answer 1

Answer: i think 8 or 7 because its -3 so +3 to the 5 minutes or 2 since it is a sprinkler hope i help $\alpha \alpha \alpha \alpha \beta x_(123) \lim_(n \to \infty) a_n$

Answer 2

Answer:

Final answer:

To find the rate at which the lawn sprinkler would fill the pool if used alone, subtract the rate of the hose from the combined rate. The equation is rs = 1/5 - 1/8.

Explanation:

To determine the rate at which the lawn sprinkler would fill the pool if used alone, we can set up an equation using the concept of rates. Let r be the rate at which the sprinkler fills the pool. If it takes 8 minutes for Byron to fill the pool with just the hose, then the rate of the hose alone is 1 pool/8 minutes, or rh = 1/8. If it takes 5 minutes to fill the pool when both the hose and sprinkler are used together, then the combined rate is 1 pool/5 minutes, or rc = 1/5.

The rate of the sprinkler alone, rs, can be determined by subtracting the rate of the hose from the combined rate. Thus, we have rs = rc - rh. Substituting the given values, we have rs = 1/5 - 1/8.

Therefore, the equation that can be used to determine the rate at which the lawn sprinkler would fill the pool if used alone is rs = 1/5 - 1/8.

7 x 3/4

Answers

If you would like to calculate 7 * 3/4, you can do this using the following steps:

7 * 3/4 = 21/4 = 5 1/4

The correct result would be 21/4.

The equivalent value of the expression is A = 21/4

Given data:

The first number is represented as a = 7

The second fraction is represented as b = 3/4

So, the equation is A = ab

And, A = 7 x 3/4

So, 7 multiplied by 3/4 equals 21/4.

However, to express the answer in its simplest form, we can simplify the fraction by dividing both the numerator and denominator by their greatest common factor.

The greatest common factor of 21 and 4 is 1, so we divide both numerator and denominator by 1.

Hence, the simplest form of the equation is A = 21/4
