Answer:
the first one is m, the second one is 5
Answer:
82
Step-by-step explanation:
180+148+xy=360
xy=32
arc=32=double the angle=16 degrees
Since both are radii they are equal. It is an isoceles triangle so angle x equals angle y.
180=16=164/2=82
1. x+5y=8
2x- 5y=1 What you do is find the number/variable that are the same( here is is the +5y and -5y. You want them to be opposites(-,+) so that they cancel each other out. if they are not opposites, then multiply one equation by a negative sign to change it. Cross out the 5y's. Now you can combine like terms-x+2x=3x, and 8+1=9, so now your equation will look like this:
3x=9
x=9/3
x=3
now take x=3 and plug it into the first equation to solve for y. x+5y=8, so 3+5y=8
5y=8-3
5y=5
y=5/5
y=1
(3,1) are your answers.
now do the same with the other problems.
1 revolution = circumference of the wheel = pi * diameter
= 3.14 * 7 inch
so 100 revolution = 100 * 3.14 * 7 = 2198 inches
= 2198 / 12 = 183.17 feet
