First, write an equation to express what you know.
g = number of girls
b = number of boys
b * 2.52 + g * x = 2.88(b+g)
Solve for x, first substitute known values for g and b
12 * 2.52 + 18 * x = 2.88(12+18)
Add and multiply what you already know
30.24 + 18x = 86.4
Subtract 30.24 from both sides
18x = 56.16
Divide both sides by 18
x = 3.12
Therefore the GPA of the girls is 3.12</span>
Answer:
8 miles
Step-by-step explanation:
6 + 10 + 8 = 24
24/3 = 8
In order to use the Law of Sines, EF has to be the included side. Therefore, we need to calculate angle F which is 72 degrees.
side f / sine (F) = side d / sine (D)
side f / sine (72) = side 24 / sine (45)
side f = sine (72) * 24 / sine (45)
side f = 0.95106 * 24 / .70711
side f (DE) =
