Answer:
c 4.1 inches
Step-by-step explanation:
The circumference of a circle is given by
C = 2*pi*r
The sector is only 78 degrees
Take the fraction of a circle and multiply by the circumference to find the length x
x = C* 78/360
= 2 * pi *r * 78/360
= 2 * pi *3 * 78/360
Using 3.14 for pi
= 4.082
Rounding to the nearest tenth
x = 4.1 inches
3x-2-1=2-5x+5
3x-3= 3-5x
3x=5-5x
8x=5
Answer:
1. slope formula?
2. (0,6)
3. y= -3x+6
Step-by-step explanation:
because the original formula to make a like is y=mx+b.
just plug the values you have into the equation knowing that m is the slope and b is the y intercept.
the slope would be rise/run which in this case the rise is -6 and the run is 2.
so m= -6/2 = -3
and b = 6 because x is 0 when y is 6 for this graph.
(btw I put -6 as the rise because you are going down 6 units instead of going up)
6 1/10 because 3 3/5 equals 3 6/10 and 2 1/2 equals 2 5/10. 3 6/10 plus 2 5/10=6 1/10
Answer:
D because 6/30 is not the same as 2:10
