Answer:
Distance covered by hula hoop rolls in 4 full rotations is 880 cm .
Step-by-step explanation:
Formula
Where r is the radius of the circle.
As given
Allison is rolling her hula hoop on the playground.
The radius of her hula hoop is 35 cm.
r = 35 cm
Putting the value in the formula
= 220 cm
As given
The hula hoop rolls in 4 full rotations.
Distance covered by hula hoop rolls in 4 full rotations = 220 × 4
= 880 cm
Therefore the Distance covered by hula hoop rolls in 4 full rotations is 880 cm .
Solution: The amount of wheat produced by the world 
metric tons.
We know that 
We are given that Canada produced 
of world production.
Therefore, the amount of wheat produced by Canada is:
metric tons
Hence the 
metric tons are produced by Canada.
Answer:
I believe the answer is the second one. Hope this helps :))
First, find your total sales. You do this by adding all the sales together, 2030+1540+1800=5370. Now, for each person, divide their sales by total sales.
Lola) 2030/5370=203/537≈0.378=37.8%
Ahmed) 1540/5370=154/537≈0.287=28.7%
Tommy) 1800/5370=180/537=60/179≈0.335=33.5%
You have the ratio set up correctly:
2x+2/12 = x+3/21
Now cross multiply:
2x+2 * 12 = x+3 * 21
Simplify:
24x + 24 = 21x + 63
Subtract 24 from each side:
24x = 21x + 39
Subtract 21x from each side:
3x = 39
Divide both sides by 3:
x = 39/3
x = 13
