84 kilometers ... 1 hour
7 kilometers ... x hours = ?
If you would like to know how long does the pigeon take to fly 7 kilometers, you can calculate this using the following steps:
84 * x = 1 * 7
84 * x = 7 /84
x = 7/84
x = 1/12 hour
Result: A pigeon can fly 7 kilometers in 1/12 hour.
Solution: The correct option is d. 8.75
<u>Explanation:</u>
The formula for variance is:

of the given data:

Now let's find
, please have a look at the attached picture:

Answer:
b perpendicular
Step-by-step explanation:
all that is needed to do is the Y2 - y1 / X2 - X1 formula and then compare the two slopes making sure they are inverse opposites
Line 1) -7 -8 / -3 -2 X= 3X
Line 2) -3 - 0 / 12 - 3 X = -1 / 3X
Because they are inverse opposites of each other they are perpendicular had they had the exact same slopes they would have been parallels.
Answer:
82 is 42 degrees warmer than 40
Step-by-step explanation:
if you subtract 40 from 82, you get 42 meaning that the answer will be 42 degrees more than 40
Answer:
400 < m< 430 kg
Step-by-step explanation:
the mass of horse is 429 kg
estimated to the nearest hundred is 400 kg
estimated to the nearest tens is 430 kg
thus the value of m mass lies between 400 to 430
therefore
400 < m< 430 kg
