Answer: 16 rotations
Step-by-step explanation:
Given : Shawn is coasting down a 500 cm long ramp on his inline skates. The wheels on his inline skates are 32 cm in circumference.
Length of ramp = 500 cm
Circumference of wheels = 32 cm
Formula :
Number of rotations = Length of ramp divided by Circumference of wheels
= 500 cm ÷ 32 cm
= 15.625 ≈ 16 [approx]
Therefore, each wheel makes 16 rotations while Shawn is coasting down the ramp.
Area=legnth times width
a=lw
area=432
width is 3/4 its lenth
w=3/4 times l
subsitute
a=l(3/4 times l)
a=432
432=l(3/4 times l)
432=3/4l^2
multiply both sides by 4/3 to clear fraction
1728/3=l^2
576=l^2
take the squaer root of both sides
24=l
subsitute
w=3/4l
w=3/4(24)
w=18
legnth=24 feet
width=18 feet
Answer:
x = 20
Step-by-step explanation:
The sum of the three angles in the diagram is 180 degrees since they form a straight line
x + 100 + 3x = 180
Combine like terms
100 +4x = 180
Subtract 100 from each side
100+4x-100 =180-100
4x= 80
Divide each side by 4
4x/4 = 80/4
x = 20
