Last summer, the Abrams family had a 30-gallon baby pool that they could fill in just 2
minutes. This summer, they purchased a larger kiddie pool that holds 150 gallons of water.
If the Abrams fill the larger pool at the same rate, how long will it take to fill it?

Answers

Answer 1

Answer:

10 mins

Explanation:

Because it takes 2 minutes to fill a 30 gal pool, and 150/30=5, 2 x 5 = 10 giving you the answer of 10 mins to fill a 150 gal pool.

Answer 2

Time taken to fill the larger kiddie pool that holds 150 gallons of water is 10 minutes.

Given that, the Abrams family had a 30 gallon baby pool that could fill in just 2 minutes.

What is the unitary method?

The unitary method is a technique for solving a problem by first finding the value of a single unit, and then finding the necessary value by multiplying the single unit value.

Now, rate of filling the pool = 30/2

= 15 gallons per minute

So, time taken to fill 150 gallons of water

= 150/15

=10 minutes

Therefore, time taken to fill the larger kiddie pool that holds 150 gallons of water is 10 minutes.

Find an equation of a line containing the point (-6,3) and has slope
- 1/3

Answers

Answer: y=-1/3x+1

Step-by-step explanation:

To find an equation that contains the given point and has the same slope, we can plug it into slope-intercept form to find the y-intercept.

3=-1/3(-6)+b         [multiply]

3=2+b                   [subtract both sides by 2]

b=1

Now that we know the y-intercept, we know that the equation is y=-1/3x+1.

Al sumar su doble, su mitad y 15 se obtiene 99.

Answers

Answer:x = numero

2x= doble

x/2= mitad

sumamos todo : x+2x+x/2+15=99

7x/2= 99-15

7x= 84(2)

x=168/7

x=24

comprueba sumando 24+48+12+15=99 suerte!!!

Step-by-step explanation:

The value of the unknown number is 33.6

Let the unknown number be "x"

The half of the number is 0.5x

Double of the number is expressed as 2x

Adding this functions together and 15 and equating to 99 will give;

0.5x + 2x + 15 =99

Solve for x

2.5x = 99 - 15

2.5x  = 84

x = 84/2.5

x = 33.6

Hence the value of the unknown number is 33.6
