Answer:
<h2>312.7 in^2</h2>
Step-by-step explanation:
This problem is on the mensuration of flat shapes, sectors and arc.
we know that the area of a sector is given as
A=(∅/360)*πr^2
Given that the length of the wiper R=24 in
and the length of the blade r= 16in
To find the area of the wiped surface we only require the length of the blade as the radius
The area of the wiped surface is given as= (140/360)*3.142*16^2
A= 0.3888*3.142*256
A=312.7 in^2
Answer:
Step-by-step explanation:
<u>Solving for A:</u>
- Given
- Divide both sides by 3x-8 to isolate a
- Simplify
<u>Solving for B:</u>
<u /> - Given
- Distribute the parenthesis (distributive property)
- Add 18x to both sides to isolate b
The correct answer is: B.
Answer:
Blue = 12/58 * 100% = 20.68 = 21%
Red = 6/58 * 100 = 10.34 = 10%
Yellow = 21/58 * 100 = 36.20 = 36%
Black = 8/58 * 100 = 13.79 = 14%
Green = 11/58 * 100 = 18.96 = 19%
Step-by-step explanation:
Given the table :
Marble_color ____ Number of marbles
Blue ___________ 12
Red ___________ 6
Yellow _________ 21
Black __________ 8
Green _________ 11
Theoretical probability % = (number of favorable outcome / number of total possible outcomes)
Total possible outcomes = (12+6+21+8+11) = 58
Blue = 12/58 * 100% = 20.68 = 21%
Red = 6/58 * 100 = 10.34 = 10%
Yellow = 21/58 * 100 = 36.20 = 36%
Black = 8/58 * 100 = 13.79 = 14%
Green = 11/58 * 100 = 18.96 = 19%
