In this problem WP means what percent
20 = WP X 160
solve for WP, by dividing both sides by 160
and you get:
0.125 = WP
Change your decimal into a percent by multiplying by 100%
12.5% is your result.
Answer: Quest 1 final result. (I looked all this up)
(2x -1) * (5x squared - 2x + 6)

I could not find the work for part two but I got the answer: x=3,7
The correct answer is the option D, which is: <span>D. 78 cm; 39 cm; 30.3π cm
The explanation is shown above:
1-The formula for calculate the circumference of a circle is:
C=2</span>πr
78π=2πr
2- The radius is:
r=78π/2π
r=39 cm
3- The diameter is:
D=39 cm x 2
D=78 cm
4- The arc length is:
arc length=(140°π/180°)(39 cm)
arc length=30.3π cm
Answer:
x = 14 units
Step-by-step explanation:
- Distance of both the chords from the center of the circle is 9 units.
- -> Both the chords are equal. (Chords equidistant from the center of the circle are equal)
- Perpendicular drawn from the center of the circle bisects the chord.
- -> Measure of one chord = 7 + 7 = 14 unit
- -> Measure of the other chord = 14 units
Answer:
false
