If a wheel makes a full turn, it will have traveled the entire distance around that wheel. After 3 revolutions, it should have traveled 3 times its circumfrence.
The circumfrence of a circle is equal to the diameter times pi. (about 3.14)
21 × 3.14 = 65.94 = circumfrence = 1 revolution
3 revolutions = = 65.94 × 3 = D. 197.82 in.
Answer:
Isosceles triangle
Step-by-step explanation:
Length of side AB = 
= 
= 
= 
= 4
Length of BC = 
= 
= 
Length of AC = 
= 
= 
Since, AC = BC, ΔABC will be an isosceles triangle.
Answer: Strong positive correlation, 0.9663
Step-by-step explanation:
Easy. your starting point is going to be at -2 on the y-axis. then from that point (-2) you're going to go down 1 and then over 2. then draw a straight line through those two points. The line should be a negative line.
