a bottle contains 24.5 oz of water. a leak in the bottle causes it to lose 0.3 oz of water every minute. how many minutes does it take for the bottle to lose 33% of the water?

Answers

Answer 54.7 Minutes

Step-by-step explanation:

33% × 24.5 =

(33 ÷ 100) × 24.5 =

(33 × 24.5) ÷ 100 =

808.5 ÷ 100 =

8.085 ≈

8.09;

so then 8.09 - 24.5 = 16.41

16.41 divided by 0.3 = 54.7

54.7 minutes it take for the bottle to lose 33% of the water.

What is Percentage?

The percentage formula is used to calculate the amount or percentage of anything in terms of 100. Percentage indicates "per hundred" in its most basic form. The percentage formula is used to express a number between zero and one. It is a number that is expressed as a fraction of 100. It is represented by the sign% and is mostly used to compare and find ratios.

We have a bottle contains 24.5 oz of water.

A leak in the bottle causes it to lose 0.3 oz of water every minute.

So, 33% × 24.5

= (33 ÷ 100) × 24.5

= (33 × 24.5) ÷ 100

= 808.5 ÷ 100

= 8.085

= 8.09

So, the amount water loses

= 24.5 - 8.09

= 16.41 oz

Now, the amount of time for bottle to loose 33% of water

= 16.41 / 0.3

= 54.7 minutes

Answers

Answer:

y = 1 + -1Y

Step-by-step explanation:

Simplifying

13y + 2 + -2y = 10y + 3 + -1Y

Reorder the terms:

2 + 13y + -2y = 10y + 3 + -1Y

Combine like terms: 13y + -2y = 11y

2 + 11y = 10y + 3 + -1Y

Reorder the terms:

2 + 11y = 3 + -1Y + 10y

Solving

2 + 11y = 3 + -1Y + 10y

Solving for variable 'y'.

Move all terms containing y to the left, all other terms to the right.

Add '-10y' to each side of the equation.

2 + 11y + -10y = 3 + -1Y + 10y + -10y

Combine like terms: 11y + -10y = 1y

2 + 1y = 3 + -1Y + 10y + -10y

Combine like terms: 10y + -10y = 0

2 + 1y = 3 + -1Y + 0

2 + 1y = 3 + -1Y

Add '-2' to each side of the equation.

2 + -2 + 1y = 3 + -2 + -1Y

Combine like terms: 2 + -2 = 0

0 + 1y = 3 + -2 + -1Y

1y = 3 + -2 + -1Y

Combine like terms: 3 + -2 = 1

1y = 1 + -1Y

Divide each side by '1'.

y = 1 + -1Y

Simplifying

y = 1 + -1Y

CFMS has contacted a band to play at an upcoming event. The band will charge a travel fee of $525 plus $12.50 per ticket sold.The school decides to turn the event into a fundraiser by increasing the cost of the tickets. If they want to make a profit of $875, how much will they need to charge per ticket?

Answers

Answer:

x=28 so they need to charge 28 tickets

Step-by-step explanation:

525 + 12.50x=875

First, take the 525 and drag it to the other side which will become into negative so the equation will be 12.50x=875-525 now just subtract it and u will get the answer of 12.50x=350 now all you need to do is divide [tex]\frac{350}{12.5}[/tex] and now the answer will be x=28 to double check we can just multiply 12.5 times 28 =  350 now plus 525 is = to 875 hope this helped :>
