Plans say that 1800 gallons of water are recycled through the water rush ride each minute. Ms Luca wants to make a statement about the number of quarts of water that are recycled each second. What should her statement be? Show your work.

Answers

1800 gal converts to 7200 quarts, and divide that by 60 you get 120 quarts of water per second.
well first you would have to divide 1800 by 60 (because there are 60 seconds in a minute). which would equal 30. then divide that by 4 which would be 7.5. and theres your answer. 7.5 quarts per second.

5%=.05
$30 x .05 = $1.5
Take $1.5 off of the $30.
After discount, the price was $28.5.
Sales price needs to be added.
$28.5 x .05 = $1.4
$28.5 + $1.4 = $29.9
$29.9 is the final price of the  wind chime.

Answer: 29.9

How to solve this problem

5%=.05

$30 x .05 = $1.5

Take $1.5 off of the $30.

After discount, the price was $28.5. Sales price needs to be added.

$28.5 x .05 = $1.4
$28.5 + $1.4 = $29.9

$29.9 is the final price of the wind chime.

Answers

you bring the decimal point 2 places to the right.

answer is A
We want to write the decimal number 0.035 in percent form. So, to convert this value to percent, we just multiply it by 100.
In this example multiplying 0.035 by 100, we get 3.5 (the value in percent).

Step 1: Move the decimal point two places to the right: 0.035 → 0.35 → 3.5.
Step 2: Add a % sign: 3.5%So, 0.035 is equivalent to 3.5% in percent form.

Frank cut a pie into 10 equal slices. There are only 3 slices left. what is the measure of the angle for 3 slices that are left?

Answers

Answer: 108°

Step-by-step explanation:

A pie is 360°.

From the question, Frank cut a pie into 10 equal slices. This means each pie will be:

360° ÷ 10 = 36°

Since 3 slices are left, that means that the total measure of the angle of the 3 slices left will be:

= 36° × 3

= 108°

The measure of the total angle for 3 slices that are left is 108°.
360/10x3

the angle of the whole pie (a circle) equals 360°. he cut it into 10 pieces so each piece degree measurement is 36 (360°/10) and then there are 3 slices so together that's 108° (36°x3)
