Answer:a
Step-by-step explanation:
15.6 - 11.7 = 3.9
3.9 ÷ 15.6 = .25
25% of change
Get the unit rate.
90 / 12 = 7
$7.50 for a sun visor.
15 * 7.5 = 112.5
The athletic director needs to pay $112.5 to buy 15 more sun visors.
Answer:
D
Step-by-step explanation:
D is the correct answer
We are given that the angle a is the right angle. So let
us work from this.
ab = 12 (the vertical side of the triangle)
bc = 13 (which if drawn can be clearly observed to be the
hypotenuse) = the side opposite to angle a
ca = 5 (the horizontal side of the triangle)
Since we are to find for the cosine ratio of angle c or
angle θ, therefore:
cos θ = adjacent side / hypotenuse
cos θ = ca / bc
cos θ = 5 / 13
Check out the attached image below for the illustration
of the triangle.
