Answer: 5500cm.
Step-by-step explanation:
A revolution corresponds to circumference of the bicycle wheel.
The radius of the circle = 70/2 since two radii makes a diameter.
Therefore r = 35cm
Circumference of a circle = 2πr or πd where π = 3.142 or 22/7
We now have = 2 x 22/7 x 35
Therefore 0ne revolution = 220cm.
Therefore, the distance traveled by making 25 revolution
= 220 x 25
= 22000/4
= 5500cm.

Answer:
x^2 -3x +15
Step-by-step explanation:
7x^2 +6x -9x - 6x^2 +15
Combine like terms
7x^2 - 6x^2 +6x -9x +15
x^2 -3x +15
Answer:
17
Step-by-step explanation:
b(n)=b(n-1)+1 means a term can be found by taking it's previous term and adding 1 to it.
So if b(1)=16, the next term b(2)=16+1=17.
