Answer:
Step-by-step explanation:
cos(50°) = 13/x
x = 13/cos(50°) ≅ 20.2
Answer: 75 students
Step-by-step explanation:
15% of 500= 75
F(x)=3-2x
g(x)=(1/x)+5
(f/g)(8)
f(8)=3-2(8)
f(8)=3-16
f(8)=-13
g(8)=(1/8)+5
g(8)=5.125, or 41/8
(f/g)(8)=(-13)/(41/8)
(f/g)(8)=-104/41, or -2.536585366
Answer: -4.5n - 4
Calculation/Explanation:
Distribute;
9 + (0.5)(7n) + (0.5)(-26) + -8n
= 9 + 3.5n + -13 + -8n
Combine Like Terms:
= 9 + 3.5n + -13 + -8n
= (3.5n + -8n) + (9 + -13)

Answer:
See Below
Step-by-step explanation:
A)
There are two runners that run at different average speeds, let these be Ra (runner a) and Rb (runner b). We also have two differnt distances that can be ran, let Leg A La and Leg b Lb. We get the equation bellow:

B)
Mickey = 35km/h
Minnie = 25km/h
Leg A = 30
Leg B = 20
Since Mickey is the fastes, he should run the section with the longest distance:
