Answer:

Δn=3
Step-by-step explanation:
Remember, if we need to divide the interval (a,b) in n equal subinterval, then we need divide the distance (d) between the endpoints of the interval and divide it by n. Then the width Δn of each subinterval is d/n.
We have the interval [-5,7]. The distance between the endpoints of the interval is
.
Now, we divide d by 4 and obtain 
Then, Δn=3.
Now, to find the endpoints of each sub-interval, we add 3 from the left end of the interval.

So,

4.55 divide by 3 1/4 = 1.4 dollar per one pound.
What we Know: 3 box have some counters. There are 63 counters when they are all combined.
A and B counters = 36
The difference between A and C is 10.
Since we already know A and B we can subtract them from 63 to get C
C= 63- 36 = 27
Now we have to find A by looking for what number gives us the difference of 10 when subtracted from C.
36 = 18+ 18 or 19+ 17
18 and 18 wont work because it does not give us the difference of 10.
So A = 17 counters and B = 19 counters.
Answer:
185.04 mm
Step-by-step explanation:
The perimeter is 1/2 of the circumference plus the diameter
We need to go around the semicircle on the outside plus across the middle
1/2 C + d
1/2 2*pi * r + 2r
pi *r +2r
3.14 (36) + 2 (36)
113.04+72
185.04
