8.82 minutes

22.05 minutes

21.15 minutes

21.05 minutes

Answers

Answer 1

Answer:

22.05 minutes

Step-by-step explanation:

7.2 + 7.35 + 7.5 = 22.05 minutes

Answer 2
22.05 minutes

7 + 7 + 7 = 21
.2 can be rounded to .20 and .5 to .50
.20 + .35 + .50 = 1.05
21 + 1.05 = 22.05

Walmart marked up a bottle of nail polish 150% in order to make profit. if Walmart sells the nail polish for $8.75, what was the original cost of the polish?

Answers

The original price of the nail polish with a 150% markup sold at $8.75 is $3.50.

Let x be the original price of the polish.

Walmart marked up 150%.

Selling Price = Original Cost + Mark-up

therefore the selling price = x + 150% of x

we know the selling price is $8.75

Therefore, substituting the values:

8.75 = x + 150% of x

convert percentages to decimals:

8.75 = x + 1.5x

combine like terms:

8.75 = 2.5x

divide by 2.5 into both sides:

3.5 = x

use reflexive property:

x = $3.50

Thus, the original price of the nail polish is $3.50.

water drains out of the bathtub at a rate of 5 gallons in 2 1/4 minutes. how much water drains out of the tub each minute?

Answers

Answer:

[tex]2~2/9[/tex] gallons per minute

Step-by-step explanation:

If it drains at a rate of [tex]x[/tex] gallons in [tex]y[/tex] minutes, the tub drains [tex]x/y[/tex] gallons in [tex]1[/tex] minute.

We can plug in for [tex]x[/tex] and [tex]y[/tex] for this equation!

The amount it drains in one minute is [tex]5/(2~1/4)=5/(9/4)=20/9=2~2/9[/tex].

So, the answer is [tex]\boxed{2~2/9}[/tex] gallons per minute.

The quantity of water that drains out of the tub each minute is 2.23 gallons.

What is an expression?

The mathematical expression combines numerical variables and operations denoted by addition, subtraction, multiplication, and division signs.

Mathematical symbols can be used to represent numbers (constants), variables, operations, functions, brackets, punctuation, and grouping. They can also denote the logical syntax's operation order and other properties.

Given that water drains out of the bathtub at a rate of 5 gallons in 2¹/₄ minutes.

2¹/₄ minuts = 5 gallons

1 minute = 5 / 2¹/₄

1 minute = 5 /2.25

1 minute = 2.23 gallons

Therefore, the quantity of water that drains out of the tub each minute is 2.23 gallons.

a girl scout has (5x-12) boxes of cookies and sells (3x+18) of them. Write an expression to represent the amount of boxes she has left. i need help.

Answers

Answer:

2x - 30

Step-by-step explanation:

You have to subtract 3x + 18 from 5x - 12:

=> 5x - 12 - ( 3x + 18) = 5x - 12 - 3x - 18 = 5x - 3x - 12 - 18 = 2x - 30

The first step was to apply distributive properties to get rid of the parenthesis, after that the terms were arranged and the like terms combined

Answer = 2x - 30

(5x-12)-(3x+18)

Simplified becomes 2x-30
