Answer:
The distance the hula hoop rolls in 4 full rotations is 880 cm.
Step-by-step explanation:
Given : Allison is rolling her hula hoop on the playground. The radius of her hula hoop is 35 cm.
To find : What is the distance the hula hoop rolls in 4 full rotations?
Solution :
The radius of her hula hoop is 35 cm.
Perimeter of hoop =
Distance of hoop in 1 rotation =
Distance covered in 4 rotations =
Hence, the distance the hula hoop rolls in 4 full rotations is 880 cm.
Answer: 5.2×103. = 5.2×1000. = 5200
Step-by-step explanation:
Answer:
3, 12
Step-by-step explanation:
"x" is the larger number,
"y" is the smaller number.
Given
x + y = 15
x / y = 4
manipulate the equations for the problem
x / y = 4
*y *y
x = 4y
solve the system of equations by the methord of substitution:
x + y =15
4y + y = 15
5y = 15
y = 3
Subsitute back into the equations given.
x = 4y
x = 12
