Answer: The wheel make 315 complete revolutions in one minute
Step-by-step explanation: Given speed of convertible =45 miles/hr
To answer this question you will need to know how many inches the car travels Per minute.
1. To find this out you will first divide 45 miles by 60 to get the number of miles per minute.
The convertible travels 0.75 mi./min.
2. Next you will convert this number of miles to inches.
There are 63,360 inches per mile.
0.75 x 63360 = 47520 inches per minute.
3. You then need to find the distance the wheel travels in one rotation. You will need to find the circumference of the wheel.
C = pi x d
3.14 x 48
C = 150.72 inches
Each rotation is about 150.72 inches.
4. Finally, divide the total distance traveled in a minute by the circumference(distance of one rotation) to get the total number of rotations in a minute.
47520/150.72 is about 315.3 rotations per minute.
Answer:
y = −4
Step-by-step explanation:
explain more for me to understand better pls
Answer:
y=4x
Step-by-step explanation:
X would be the blue and the 4 represents the number of which each blue is increased by.
4(1)=4
4(2)=8
4(3)=12
4(4)=16
4(5)=20
and so on
hope this helped
Step-by-step explanation:
2 horror and 6 drama DVDs.
Let x be the no. Of horror dvds
15 = 7+ x+x+4
4=2x
x=2
