Answer:
theta = 60
Step-by-step explanation:
let the radius BE R
and angle be theta
formula
theta/360 x pi r2= 1/6 x pi r2
pi r2 gets canceled on both sides
theta/360 = 1/6
theta = 360/6
= 60
I think the answer is the second one, Tessa wasn't sure how far she would swim during the first class. She would swim 3 laps during the second class. The question is confusing, because the equation s+3 is supposed to be the DISTANCE she swam in 2 classes. The problem didn't specify that distance equals laps, but I think the answer is correct
Factor top and bottom, cancel like-terms
Answer:
Step-by-step explanation:
x+2y=23
2x+3y=39
y = -1/2x + 23/2
y = -3/2x + 13
Add/Elimin method
-2x - 4y = -46
2x + 3y = 39
-y = -7
y = $7 student/child ticket
x +2(7)= 23
x + 14 = 23
x = $9 adult ticket
x= $9 adult ticket
y = $7 student/child ticket
