Answer:
87
Step-by-step explanation:
Umm ok, thanks that was easy points!
If you flip it, you see 86 ... 88, so the middle number is 87!
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!
divide total miles by time:
220 / 3.5 = 62.857
rounded to nearest tenth = 62.9 miles per hour
Ratio of rise can also mean the slope so let's find the slope given the two points.
slope formula;
m = y2 - y1/ x2 - x1 (3, 4), (-2, 0) (x1, y1), (x2, y2)
m = 0 - 4/ -2 - 3
m = -4/-5
m = 4/5
so your answer is B.
hope this helps, God bless!
