Answer:
HUNDREDS
Step-by-step explanation:
You will need 292.5 mL of the 10% solution and 2925 mL of pure alcohol.
<h3>What is Algebra?</h3>
The analysis of mathematical representations is algebra, and the handling of those symbols is logic.
You require 450 mL of a 65% alcohol solution.
On hand, you have a 10% alcohol mixture.
Then the amount of the 10% alcohol mixture and pure alcohol that you need to obtain the desired solution will be
Let x be the amount of the 10% of alcohol is needed.
Then the equation will be
⇒ 450 · 0.65
⇒ 292.5 mL pure alcohol
Then the alcohol mixture will be
0.1x = 292.5
x = 2925 mL of alcohol mixture
You will need 292.5 mL of the 10% solution and 2925 mL of pure alcohol.

Answer:
76 teenagers went to movies in the past month.
Step-by-step explanation:
The number of teens who went to movie out of every 5 teens = 4
Total teens surveyed = 95
Let, out of 95 teenagers , the teens who went to movie = m
So, the ratio of people who went : who were surveyed = 4: 5
Now, <u>BY THE LAW OF RATIO AND PROPORTIONALITY</u>
<u />
or,
So, m = 76
⇒ 76 teenagers went to movies in the past month.
