Answer:
Option A) angle bisector
Step-by-step explanation:
Angle Bisector:
- An angle bisector is a line that divides an angle into two equal parts.
- The angle bisector divide the angle in two equal parts.
- An angle bisector is equidistant from the sides of the angle when measured along a segment perpendicular to the sides of the angle.
- It cuts the angle into half.
- Thus, a sector can be divided into two equal sectors by drawing an angle bisector.
To divide the sector into two congruent sectors we can use the angle bisector construction.
Thus, the correct answer is
Option A) angle bisector
The answer will be .77 because you have to multiply then add
Answer:
I'm not a 100% sure but I think it's c if I'm wrong I'm sorry
Let L be the low copper alloy and H be the high copper alloy.
We need 0.15L + 0.60H = 0.42 and L + H = 100
L=100 - H
Substituting this into the second equation for L, we get:
0.15(100-H) + 0.60H = 0.42(H+L)
15 - 0.15H + 0.60H = 0.42(H+100-H)
15 + 0.45H = 0.42(100)
0.45H = 42 - 15 = 27
H = 27/.45 = 60 lbs
Back substitution, L = 40 lbs.
There are 3,300 different ways to select the committee.
First, we need to determine the total number of ways the 6 members can be selected.
For the chair and vice chair, it would be 5 x 4 = 20, but then that has to be divided by 2. (Because the order doesn't matter)
20 / 2 = 10
For the rest, it would be 11 x 10 x 9 x 8 = 7920, but again divide it by 4! because the order doesn't matter.
7920 / 24 = 330
To find the total ways for both, multiply 10 by 330 to get 3300.
