Answer: 13 whole pieces of wire can be cut from that spool and 
of wire is left over.
Step-by-step explanation:
Convert from mixed number to improper fraction. To do it you must multiply the whole numbe part by the denominator of the fraction and then add the product to the numerator. The denominator does not change. Then:
Since the spool contains 100 inches of wire, you must divide this lenght by 
:
Convert from improper fraction to mixed number:
- When you divide the numerator 800 by the denominator 59, the quotient is 13 (this is the whole number part)
- The remainder is 33 (This is the numerator of the fraction).
- The denominator does not change.
Then:
Therefore 13 whole pieces can be cut from that spool.
The amount of wire left over is:

Answer:
x=9
Step-by-step explanation:
So first subtract 8 on both Sides
3x+8-8=35-8
3x=27
Now divide 3 on both sides to isolate the variable x
x=9
So x=9
Answer:
y = -2/3x + 6
Step-by-step explanation:
Answer:
a. 
b. 
Step-by-step explanation:
a. Radius of semicircle (r) = r
Diameter of semicircle (d) = 2r
Length of rectangle (l) = 2*diameter of semicircle = 2*2r = 4r
Distance around the track (p) = circumference of circle + 2(l)
Note: the two semicircles of the track = 1 full circle
Circumference of full circle = πd = π*2r = 2πr
Distance around the track:
p = 2πr + 2(4r)
p = 2πr + 8r
b. Rewriting the formula to make radius, r, the subject of the formula in terms of distance around the track.
Factor out r
Divide both sides by (2π + 8)
