21 feet requires = 7 seconds
1 feet requires = 7/21 seconds
180 feet requires
= (7/21)*180
= (1/3)*180

Answer: Option A, the square root of 40, is an irrational number.
Step-by-step explanation:
We are given 4 options:
- the sqrt of 40
- the sqrt of 49
- the sqrt of 100
- the sqrt of 9
All but one are perfect squares. Let's find out which one is not a perfect square.
The sqrt of 49 is 7. 7 times 7 is equal to 49.
The sqrt of 100 is 10. 10 times itself is equal to 100.
The sqrt of 9 is 3. 3 times 3 is equal to 9.
What about the square root of 40?
We know it's not a perfect square, and it's somewhere between 6 and 7. So, the hint from the question tells us that imperfect squares are irrational. Then this must be the answer!
Hello!
Simply divide the numerator by the denominator to get the decimal, and then multiply the decimal by 100:
100 ÷ 100 = 1
1 × 100 = 100
100/100 as a percentage is 100%
1 ÷ 1 = 1
1 × 100 = 100
1/1 as a percentage is 100%
Answer:
50
Step-by-step explanation:
35/5 = 7
