Answer:
15%
Step-by-step explanation:
25% fail math
60% of the 25% above fail science
thus,

The conversion factor between radians and revolution as measures of angle is 2π rad is equal to 1 revolution. Converting the given angular velocity to rev/s,
(2.8 rad) x (1 rev / 6.28 rad) = 70/157 revolution per second
Dividing the given angle, 20 rev by the velocity,
(20 rev) / (70/157 rev/s) = 44 6/7 s
Thus, the answer is approximately 44.9 seconds.
Answer:
x is 12
Step-by-step explanation:
You can find x two different ways.
The first way is to look at the numbers on the left side. You need to find the scale factor used to get from 4 to 6.
4 x 1.5 = 6
Use this for the 8
8 x 1.5 = 12
The other way you can use is look at the number on the top triangle. You need to find the scale factor used to get from 4 to 8.
4 x 2 = 8
Use this for the 6
6 x 2 = 12
If you rotate the triangle 180 degrees around the origin I’ll only go half way of that triangle
Answer:
Cos C = adjecent/hypotenuse
Cos C = 14/50
divide the numerator and the denominator by 2
Cos C = 7/25
The answer is C
