The circumference of a circle is C=2πR, where R is the radius of the circle and π≈3.14.
So if we open the circumference of the circle into a straight line segment, the length of this segment is C=2πR≈2*3.14*R=6.28R
4 rotations mean 4 circumferences that is 4 segments of length 6.28R,
which makes a linear distance of 4*6.28R=25.12R
i: the radius of the smaller wheel is R=r, thus it covers a distance of 25.12r feet
ii: the radius of the smaller wheel is R=2r, thus it covers a distance of 25.12*2r=50.24r (feet)
50.24r is twice 25.12r, thus the larger wheel traveled Twice the distance of the smaller one.
Answer: the larger covered twice the distance of the smaller.
Number 1 is D becuase porportional should have a intercept of 0,0 in the origin and number D is correct

Use the GCF to write it as a distributive property
First, we find the GCF of 75 and 45
The common factor is:
So, becomes

I'm not I understand. The range is the highest value minus the lowest value, which on the graph is 10-4=6.
Answer:
36 feet long.
Step-by-step explanation:
If the longest wall in the living room is referring to the side that I have drawn over in white and red in the attached image, or if it is the leftmost wall, then that wall is 36 feet long. For every half inch, it is 6 feet, so because there are 6 'half inches' in 3, you multiply 6 feet by the 6 half inches there are, and get 36. There are simpler ways to solve it but I can't take a picture of my work, so I hope this helps. Good luck.
