Answer:
I think it will be 54.125%
To solve for the last side of the triangle, use the Pythagorean Theorem:
(8)^2 + x^2 = (9)^2
x = sqrt of 17
However, this is a NEGATIVE sqrt 17 because the terminal side is in quadrant 4, meaning that this side is under the X-axis and therefore negative.
Now that you know the side opposite of u in the triangle, do opposite/hypotenuse.
sin u = -(sqrt 17)/9
Divide commission amount by percentage:
83.50 / 0.40 = 208.75
Sales must be $208.75
Answer:
Choice B) {-21, -7, 7, 21}
Step-by-step explanation:
The multiples of 7 are: 0, 7, 14, 21, 28, 35, ... both the positive and negative versions of each number. Erase the even numbers in that list to end up with 7, 21, 35, ...
Choice A fits the description, but there are items missing, namely -7 and 7. So this answer choice is crossed off the list
Choice B has both odd numbers and multiples of 7 listed. Every number is listed. This is why this is the answer.
Choice C has multiples of 7, but these are even numbers. We can cross it off the list.
Choice D is a similar story to choice C, though it has some odd numbers in this list.
