Mr. Brown is riding his bicycle along a road that is 1 Kilometer long. Both wheels are 1 meter in diameter.
How many times does each wheel revolve on his journey of 1 Kilometer?

Answers

Answer 1

Answer:

The wheels have to rotate 500 times

Step-by-step explanation:

The wheel is 1 meter in diameter so we need to find the circumference.

C = 2[tex]\pi[/tex]r

C = 2[tex]\pi[/tex]1

C= 2[tex]\pi[/tex]

2meters = .002kilometers

1000meters = 1kilometer

1000/2 = 500

m/3 -3 < -6

The M is over the 3

Answers

Answer:

m<1

Step-by-step explanation:

m/3<3

m<1

Answer:

m < -9

Step-by-step explanation:

Simplify this by adding 3 to both sides:  m/3 - 3 + 3 < -6 + 3

This becomes m/3 < -3.

Now isolate m by multiplying both sides by 3:

3(m/3) < 3(-3) becomes m < -9

Evaluate 1/3m - 1 - 1/2n when m = 21 and n = 12

Answers

Answer:

the answer is 0.

Step-by-step explanation:

1/3(21) - 1 - 1/2(12) = 7 - 1 - 6 = 0

The Answer is zero. You just plug in the 21 for m and 12 for n.
