A street is 149m long is covered in snow. City workers are using a snowplow to clear the street. The snowplow has tires that are
1.7m in diameter. How many times does a tire have to turn in traveling the length of the street
1 answer:
Answer:
Approximately 28 times
Step-by-step explanation:
The tires are circular in shape.
We first need to find the circumference of the tire and then divide the length of the road by that circumference.
The circumference of a circle is given as:
C = πD
where D = diameter
The diameter of the tires is 1.7 m. Its circumference is therefore:
C = π * 1.7 = 5.34 m
Therefore, the number of times that the tire has to turn in traveling the length of the street is:
149 / 5.34 = 27.9 ≅ 28

Answer:
x= 1 1/3
Step-by-step explanation:
Answer:
-3y-3
Step-by-step explanation:
The difference:
7y+1 - (4y−12)= 3y + 13
Subtraction:
10- (3y+13)= -3y-3
Yes and No they both correct
The answer is C: 12.
It appears that Y will always be 1/4 of X, seeing as Y varies directly with X. When Y is 3, X will be four times that, or 12. :)
