Answer:

<em>The bicycle traveled 77.9 m</em>

Step-by-step explanation:

<u>Circumference of a Circle</u>

Given a circle of radius r, the circumference or perimeter is calculated as follows:

C =2\pi r

The radius of the bicycle wheel has a radius of r=62 cm. Converting to meters r=62/100=0.62 m.

Calculate the circumference:

C =2\pi \ 0.62

C=3.8956\ m

Given the wheel makes 80 complete revolutions, the total distance covered by the bicycle is:

D=20*3.8956\ m

D = 77.9 m

The bicycle traveled 77.9 m

How do i solve this
aleksandr82 [10.1K]
Replace g for -2 and h for 5.

(2(-2) + 9(5) -5) - (6(-2) - 4(5) +2)

Taking this one at a time,
2(-2) = -4, and 9(5) = 45.
6(-2) = -12 and -4(5) = -20

(-4 + 45 - 5) - (- 12 - 20 +2)

Let’s distribute the negative symbol to the right side.

(-4 + 45 - 5) + (12 + 20 - 2)

Then, we solve!
(-4 + 40) + (12 + 18)

(36) + (30)

= 66!

B - 1 &gt; -17 what does b equal?
Nastasia [14]

Answer:

  b > -16

Step-by-step explanation:

The inequality is given as:

           b - 1 > -17

To solve this problem, add +1 to both sides of the expression:

          b  - 1 + 1 > -17 + 1

Now;

              b > -16

So, all values for which b is more than -16 satisfy the solution for this problem.
