Answer:
The total number of students in Toby's grade is 200.
It’s just y= 17x. There’s nothing added or subtracted, or else it wouldn’t be (0,0).
Answer:
Step-by-step explanation:
580 - 58 (10% of 580) = 522
522 - discount price (20) = 502
Sally is paying 502 for her camcorder
990 - 247.5 (25% of 990) = 742.5
742.5 - 20 = 722.5
Sally is paying $502
Tabitha is paying $722.5
Answer:
![285.74\text{ inch}^2](https://tex.z-dn.net/?f=285.74%5Ctext%7B%20inch%7D%5E2)
Step-by-step explanation:
GIVEN: A bicycle training wheel has a radius of
. The bicycle wheel has a radius of
.
TO FIND: Approximately how much smaller, in square inches, is the area of the training wheel than the area of the regular wheel.
SOLUTION:
radius of bicycle wheel ![=10\text{ inch}](https://tex.z-dn.net/?f=%3D10%5Ctext%7B%20inch%7D)
area of bicycle wheel ![=\pi r^2](https://tex.z-dn.net/?f=%3D%5Cpi%20r%5E2)
putting value,
area of bicycle wheel ![=3.14\times10^2](https://tex.z-dn.net/?f=%3D3.14%5Ctimes10%5E2)
![=314\text{ inch}^2](https://tex.z-dn.net/?f=%3D314%5Ctext%7B%20inch%7D%5E2)
radius of bicycle training wheel ![=3\text{ inch}](https://tex.z-dn.net/?f=%3D3%5Ctext%7B%20inch%7D)
area of bicycle training wheel ![=\pi r^2](https://tex.z-dn.net/?f=%3D%5Cpi%20r%5E2)
putting value,
area of bicycle wheel ![=3.14\times3^2](https://tex.z-dn.net/?f=%3D3.14%5Ctimes3%5E2)
![=28.26\text{ inch}^2](https://tex.z-dn.net/?f=%3D28.26%5Ctext%7B%20inch%7D%5E2)
difference in area of bicycle wheel and bicycle training wheel
![=\text{area of bicycle wheel}-\text{area of bicycle training wheel}](https://tex.z-dn.net/?f=%3D%5Ctext%7Barea%20of%20bicycle%20wheel%7D-%5Ctext%7Barea%20of%20bicycle%20training%20wheel%7D)
![=314-28.26](https://tex.z-dn.net/?f=%3D314-28.26)
![=285.74\text{ inch}^2](https://tex.z-dn.net/?f=%3D285.74%5Ctext%7B%20inch%7D%5E2)
hence the training wheel is
smaller than regular wheel
