Mei has 60 milliliters of a solution that is​ 35% nitric acid. How many milliliters of nitric acid does the solution​ contain?
(answer this and show your work please)
The solution contains _answer here_ milliliters of nitric acid.

Answers

Answer 1

Answer:

21ml

Step-by-step explanation:

60ml. 35% acid. What is 35% of 60 ml?

÷10 to find 10%

60÷10=6

6=10%

But this is no use

because you cannot multiply 10%to get 35%

(35% is not a multiple of 10)

So we try...

10%÷2=5%

So ÷2 to find 5%

6÷2=3

So 3=5%

5%x7=35%

So, we do

3x7=21

So 35%=21

Answer 2

Answer:

21ml

The original height was _answer this_ feet.

please help me with this thank you

Answers

Answer:

9670 feet

Step-by-step explanation:

The height given (8219.5 ft) is 85% OF ORIGINAL, hence original is much higher. But how do we figure this out?

we translate word problem to equation.

8219.5 IS 85% of TOTAL

Firstly, 85% = 85/100 = 0.85

Remember, is means =

of means multiplication

So we have:

8219.5 = 0.85 * Total

Hence, total = [let total be 7]

8219.5 = 0.85 * t

t = 8219.5/0.85 = 9670 feet
