S = 7x^2....divide both sides by 7
1/7s (same as s/7) = x^2...now take sqrt of both sides
(+ - ) sqrt 1/7s = x
Answer:
8π in^2 or 25.13 in^2 to the nearest hundredth.
Step-by-step explanation:
The total area = π * 8^2 = 64π in^2
so each slice has an area of 8π in^2.
You can set up this equation as:

Because remember, 70% is equal to 0.7 and x represents the unknown value. So, let's just solve it:

So,
70% of 120 is 84.
Answer:
1/16 of a mile in one minute.
Step-by-step explanation:
1. you know that 3/4 mile = 12 mins and x mile = 1 min
2. To get 12 mins to 1 you divide the mins by 12
3. So you do the same for miles!
4. 3/4 miles divided by 12
5. which turns into 3/4 * 1/12
6. so your final answer would be 1/16 of a mile in one minute
