A scientist collected 48 water samples from local streams. Each sample was the same size, and she collected 476.2 liters of water in all. To the nearest hundredth of a liter, what was the volume of each water sample?

Answers

Answer:

Volume of each water sample is 9.92 cubic liters.

Step-by-step explanation:

Number of water samples collected by a scientist = 48

Total volume of water collected = 476.2 liters

Therefore,

Volume of each water sample = (Total volume of water collected) ÷ (Number of water samples collected by a scientist)

= [tex]476.2[/tex] ÷ 48

= 9.92 cubic liters

So, volume of each water sample is 9.92 cubic liters.

The students in Mr. Lin's class are having a car wash to raise money for a trip. They need at least
$600 to go on the trip. They have already raised $61. They make $14 for every car they wash.
The students want to know how many cars they need to wash to go on the trip.

Let c be the number of
cars the students wash. Write an inequality that represents the situation.

Answers

Answer:

14c + 61 is greater than or equal to (put the greater than symbol with the line underneath there) 600

The inequality for raising the money will be written as 14c + 61 > 600.

What is inequality?

When two expressions are connected by a sign like "not equal to," "greater than," or "less than," it is said to be inequitable. The inequality shows the greater than and less than the relation between variables and the numbers.

Given that the students in Mr. Lin's class are having a car wash to raise money for a trip. They need at least $600 to go on the trip. They have already raised $61. They make $14 for every car they wash.

The inequality will be written as,

14c + 60 > 600

Here, c is the number of the car wash.

A chemical compound requires 8 ounces of chemical A and 12 ounces of chemical B. A mixture contains 24 ounces of chemical A and 30 ounces of chemical B. How can you fix the mixture to make the chemical compound?

Answers

Add 6oz of chemical B and remove 1/3 of the total mixture.
I might always be wrong.
Explanation:
Since 8x3=24 and since 12x3=36 you need to add 6oz of chemical B to have 24oz of chemical A and 36oz of chemical B.
Take 1/3 of the total mixture to have 8oz of chemical A and 12oz of chemical B.
