Answer:
17
Step-by-step explanation:
To find the hypotenuse, you would use the Pythagorean theorem.
We can plug 8 and 15 into A and B\
We can simplify this to
64+225=
289 =
To get C by itself not squared, we can do the square root of both sides.
If we simplify, we get
17 = C or C = 17
Therefore the length of the hypotenuse is 17.
Answer:
47.6 Degree Fahrenheit
Step-by-step explanation:
Given:
The Airplane is on the ground level at a temperature 59.7 Fahrenheit. Every 1,000 feet there will be drop in temperature which is 1.1 degrees Fahrenheit.
Initial Temp = 59.7 Fahrenheit
Distance Covered = 11,000 Ft
Explanation:
This means the Ground level is zero feet as the Airplane stands there.
Later, it climbs into the sky with 11,000 altitude.
That is
For every 1,000 there is decrease in temperature of 1.1 degree Fahrenheit
Therefore, 11 times the temperature will decrease
That is
12.1 Degree temperature will drop at 11,000 feet
Therefore
Temperature at 11,000 feet will be
47.6 Degree Fahrenheit
