Answer:
The volunteers donated millimeters of blood.
Step-by-step explanation:
Given:
Total Number of Volunteers = 32
number of Volunteers failed to donate = n
Amount of blood donated by each volunteer = 470 mm
We need to find the Total amount of blood donated by the Volunteers.
Solution:
First we will find the number of volunteers donated blood.
the number of volunteers donated blood is equal to Total Number of Volunteers minus number of Volunteers failed to donate.
framing in equation form we get;
the number of volunteers donated blood =
Now we will find Total amount of blood donated by the Volunteers.
Total amount of blood donated by the Volunteers is equal to Amount of blood donated by each volunteer multiplied by the number of volunteers donated blood.
framing in equation form we get;
Total amount of blood donated by the Volunteers =
Hence The volunteers donated millimeters of blood.
So this is trig, and when it comes to right (90°) triangles, it's imperative that you know:
SOH-CAH-TOA
Sine (x) = Opposite/Hypotenuse
Cosine (x) = Adjacent/Hypotenuse
Tangent (x) = Opposite/Adjacent
*hypotenuse is always the largest side, and the one opposite the 90° angle in right triangles
therefore we'll use SOH, because the opposite of x (O) and the hypotenuse (H) are given:
Sine (x) = Opposite/Hypotenuse
Sine (x) = 32/58 = 16/29 = 0.552
Sine (x) = 0.552
now we use something called arc-sine, or
it's basically a fancy function of most advanced calculators, so we'll plug it in as:
x = 33.49° --> answer B) is correct
