Answer: 18 parent volunteers and 4 buses.
Step-by-step explanation: In order to solve this problem you must first calculate how many student will be going on the trip.
There are 8 classes of 20 students and 90% are attending, so the formula is 8 x 20 x .9 = 144 students are going.
Part A: If one parent needs to go for each 8 students you need to divide 144 by 8 = 18 parent volunteers.
Part B: The total people attending are 144 students, 18 parent volunteers and 4 teachers is a total 166 total attending to ride the bus. You need to divide 166 people by 44 on each bus = 166/44 = 3.7 buses, so they need to reserve 4 buses.

Step-by-step explanation:
Answer:
The angle subtended by the arc is 171.8873385 degrees (3 radians)
Step-by-step explanation:
The formula of the length of an arc of a sector is L = × 2 π r, where
- x is the central angle subtended by the arc
- r is the radius of the circle
∵ An arc of a sector is three times its radius
∴ L = 3r
→ Equate the formula of the length of the arc by 3r
∵ × 2 π r = 3r
→ Divide both sides by r
∴ × 2 π = 3
→ Simplify the left side
∵ x = 3
→ Divide both sides by
∴ x = 171.8873385°
∴ The angle subtended by the arc is 171.8873385 degrees (3 radians)
Answer: x=0,\root(3)(3)
Step-by-step explanation: Move all terms to the left side and set equal to zero. Then set each factor equal to zero.
