If you would like to know the change in Debra's hours, you can calculate this using the following steps:
x% of 16 hours is 22 hours
x% * 16 = 22
x/100 * 16 = 22
x = 22 * 100 / 16
x = 137.5%
137.5% - 100% = 37.5%
22 hours - 16 hours = 6 hours
The correct result would be: an increase of 6 hours, and an increase of 37.5%.
Answer:
18 out of 20% gives you 3.6
Step-by-step explanation:
False. b is the y-intercept.

Y=4x+2 because with the x at 0 and y at 2 that is the y intercept
Using trigonometric identities, it is found that the exact value of the secant of the angle is given by:
c.
<h3>How is the tangent related to the secant?</h3>
According to the following identity:
The tangent is the inverse of the cotangent, hence in this problem, we have that:
Then, the secant is given as follows:
The angle is in the second quadrant, where the cosine is negative, hence the secant also is and option c is correct, that is:
c.
