7 0

Firstly, you must divide the subject total by 100. This will give you 1% of your subject. For example, if you are working out 10% of 4,500, divide 4,500 by 100 and you will have worked out 1% of 4,500---in this case, 45. Multiply your 1% answer by the percentage you wish to find out.

Paige is filling her tub at a rate of 3/4 gallons every 2/3 minute how many gallons would be in the tub after 3 minutes?

musickatia [10]

If Paige is filling her tub at a rate of 3/4 gallons every 2/3 minute, 3.375 gallons would be in the tub after 3 minutes.

<h3>What is an arithmetic operation?</h3>

It is defined as the operation in which we do the addition of numbers, subtraction, multiplication, and division. It has basic four operators that are +, -, ×, and ÷.

It is given that, Paige is filling her tub at a rate of 3/4 gallons every 2/3 minute.

We have to find gallons that would be in the tub after 3 minutes

We can utilize multiplication for the given task,

2/3 minutes = 3/4 gallons

1 minute = 3/4 × 3/2

1 minute =1.125

3 minutes = 3 × 1.125

3 minutes =3.375 gallons

Thus, if Paige is filling her tub at a rate of 3/4 gallons every 2/3 minute, 3.375 gallons would be in the tub after 3 minutes.

Write the following inequality in slope-intercept form. <br><br> 12x-3y≤-21

Brut [27]

<span>12x - 3y ≤ -21
Subtract 12x from both sides
-3y </span>≤ -12x - 21
Divide both sides by -3.
y $\geq$ 4x + 7
