The answer is 16.5 inches
Answer:
Step-by-step explanation:
We have, 120% × x = 36
or,
120
100
× x = 36
Multiplying both sides by 100 and dividing both sides by 120,
we have x = 36 ×
100
120
x = 30
Slope = 1 because the slope is m in the equation y=mx+b
Answer: 108π inches squared
Step-by-step explanation:
Formula : Area of sector =
where , r= radius and ![\theta =](https://tex.z-dn.net/?f=%5Ctheta%20%3D)
Given : A certain car's windshield wiper has a total length of 22 inches. As the wiper pivots it clears a sector with a central angle of 120 degrees.
If only 18 inches of the wiper cleans the windshield, then we take radius of the range of wiper cleaining = 18 inches
The area of the windshield that is wiped during each swing = Area of the sector made by wiper of with a central angle of 120 degrees.
![=\dfrac{120}{360}\times\pi (18)^2\\\\=\dfrac{18^2}{3}\pi=\dfrac{18\times6}{1}\pi=108\p\text{ inches}^2](https://tex.z-dn.net/?f=%3D%5Cdfrac%7B120%7D%7B360%7D%5Ctimes%5Cpi%20%2818%29%5E2%5C%5C%5C%5C%3D%5Cdfrac%7B18%5E2%7D%7B3%7D%5Cpi%3D%5Cdfrac%7B18%5Ctimes6%7D%7B1%7D%5Cpi%3D108%5Cp%5Ctext%7B%20inches%7D%5E2)
Hence, the area (in exact form) of the windshield that is wiped during each swing is 108π inches squared.
Answer:
ft
Step-by-step explanation:
Let x be the length of each side
- Turn it into an algebraic expression:
- 14 × 14 = 196
- So, x = 196
I hope this helps!
