Answer:
Therefore,
Wind speed of a Tornado when it travels 4 miles is 121.0 miles per hour.
Step-by-step explanation:
Given:
The wind speed near the center of a tornado is represented by the equation,

Where,
d = the distance, in miles
S = the wind speed, in miles per hour.
To Find:
S = ? at d = 4 miles
Solution:
We have
.........Given
Substitute d = 4 in above equation we get,

Rounding the answer to the nearest tenth we have

Therefore,
Wind speed of a Tornado when it travels 4 miles is 121.0 miles per hour.
It would be 11 since an integer above zero is positive and an integer below zero is a negative

Answer:
1413.86 ft^2.
Step-by-step explanation:
The diameter of the circle = 50 - 2(18)
= 50-36
= 14 ft.
So its radius is 7 ft.
The total area of the blue shape
= 2(35 * 18) + 3.14*7^2
= 1413.86 ft^2.
Answer:
-4/5
Step-by-step explanation:
okay well first you have to make each fraction into improper fractions
2 1/2 going into 3/2 and -1 7/8 into -15/8
and then do keep change flip keeping the first fraction (3/2), changing the division sign into a multiplication sign, and flipping the numerator and denominator of -15/8 into 8/-15
3/2 × 8/-15 = 24/-30 = 4/-5
also
4/-5 = -4/5
