Step-by-step explanation:
1. Ratio(White to black) = 12 / [52 - 12]
Ratio(White to black) = 12 / [40]
Ratio(White to black) = 3 / 10 = 3:10
2. Ratio(Blue triangle to all) = 5 / [5+80]
Ratio(Blue triangle to all) = 5 / [85]
Ratio(Blue triangle to all) = 1 / 17 = 1:17
3. Ratio(Circle to all) = 76 / [22+76]
Ratio(Blue triangle to all) = 76 / [98]
Ratio(Blue triangle to all) = 38 / 49 = 38:49
4. Ratio(Yellow triangle to blue) = 18 / 14
Ratio(Yellow triangle to blue) = 9 / 7 = 9:7
5. Ratio(Yellow triangle to blue) = 42 / 6
Ratio(Yellow triangle to blue) = 7 / 1 = 7:1
6.Ratio(Boys to all) = 63 / [27 + 63]
Ratio(Boys to all) = 63 / 90
Ratio(Boys to all) = 7 / 9 = 7:9
Charlie buys 2.5 pounds of oranges for 3.75.
To find out how much he will pay for 1 pound of oranges, use the proportion
2.5/3.75 = 1/x
Cross multiply to get x = $1.50 per pound of oranges.
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
