Answer:
arc FG = 115°
arc EG = 165°
Step-by-step explanation:
The first step is to understand how these arcs are arranged on a circle. The next step is to realize the whole is the sum of the parts. Arcs have the same measure as their central angle. A circle totals 360°.
arc EF + arc FG = arc EFG . . . . parts of an arc add to give the whole arc
80° + arc FG = 195°
arc FG = 115° . . . . . . . . . subtract 80°
__
Similarly, parts of a circle add to give the whole circle.
arc EFG + arc EG = 360°
195° + arc EG = 360°
arc EG = 165° . . . . . . . . . subtract 195°
Answer:
4 sophomore girls .
Step-by-step explanation:
If a student's gender and class are to be independent when a student is selected at random, two conditions must be met:
n° boys = n° girls
n° freshmen = n° sophomore
Currently, there are 10 boys and 6 girls, thus 4 girls must join.
Currently, there are 10 freshmen and 6 sophomores, thus 4 sophomores must join.

Answer:
The number of units to sell is 112.
Step-by-step explanation:
Giving the following information:
Selling price= $4
Total cost= $86.56
Desired profit= $100
<u>To calculate the number of units to be sold to reach the objective, we need to use the following formula:</u>
Desired profit= number of units*selling price - total cost
100= number of units*4 - 86.56
25= number of units - 86.56
111.56=number of units
The number of units to sell is 112.
