Answer:
4.19 inches
Step-by-step explanation:
Your goal is to find the circumference of the donut and then divide that by 3 to get 1/3 of the outer edge of the donut.
Circumference is 2
r
The diameter (double the radius) is 4, so radius (r) is 2
2 * pi * 2 = 4 pi = 12.57 (round to hundredth)
12.57/3 = 4.19
keep in mind that dividing by 3 is the same as multiplying by 1/3
The answer is “Yes, Mr. Yule’s sample is random and representative of the population” cause he randomly chose people from all greases
Answer:
-1
Step-by-step explanation:
The required relation is ...
7n = n^2 -8
0 = n^2 -7n -8 . . . . put in standard form
0 = (n -8)(n +1) . . . . factor
Solutions are n=8 and n=-1.
The negative solution is -1.
Answer:
-167.2 ft/mile
Step-by-step explanation:
The "rise" is 1298 -1776 = -478 ft. The run is given as 15,098 ft, so the slope is ...
slope = rise/run = -478/15098 ≈ -0.0316598
For 5280 feet in 1 mile, that rate of change amounts to ...
-0.0316598×5280 ft ≈ -167.2 ft . . . per mile
The answer would be: X=26
