Wat if I don’t want to answer it? R u going come and fight me?
Answer:
C
Step-by-step explanation:
so m is less than o and m is less than n so that means m is the shortest angle (look at the picture) as you see NO is the longest side since theres only one answer that has NO as the first choice it has to be that one.
15% as a decimal is 0.15
Multiply the amount of the bill by the percentage:
54.83 x 0.15 = 8.22

Explanation:
We view the ramp as a right triangle. The hypotenuse is 4.2 and the vertical side .7, which is opposite the angle
θ
we seek.

I'm going to finish the problem but I'll note if we were actually building the ramp we don't need to know the angle; this sine is sufficient.

which I think is a pretty steep ramp for a wheelchair.
There will be another inverse sine that is the supplementary angle, around

, but we can rule that out as a value for a ramp wedge angle.
Answer:
Since both terms are perfect squares, factor using the difference of squares formula.
(x+9y)(x−9y)
