Answer: 2041 meters
A bicycle wheel is a circular object.
The circumference of a circle is 2π(radius)
Here given:
- radius = diameter/2 = 65/2 = 32.5 cm
Hence find the length for each revolution:
- 2π(32.5) = 204.1 cm per revolution
Then for 1000 revolutions:
- 204.1 × 1000 = 204100 cm ≈ 2041 meter
I’m not sure but one of the numbers could be 1 and the other could be 0.5. These are possible answers that could go in the boxes. I got this because I knew that I had to get a number that’s less than 10. So when you do 8+1 you get 9 which is less than 10. I picked 0.5 because it said in the question we can’t pick the same number so I picked a decimal. When you do 8+0.5 you get 8.5 which is less than 10.
Hope this helped

Answer:
A
Step-by-step explanation:
3x^2 - 8x + 4 = 0
x= [-b +or- square root (b^2 - 4ac)] ÷ 2a
= [-(-8) +or- square root (-8)^2 - 4(3)(4)] ÷ 2(3)
= [8 +or- square root 16] ÷ 6
= 2 or 2/3
