Answer:
$54.35
Step-by-step explanation:
The differences from the average value are;
2.60, 5.00, -1.75, -4.25, -0.95
The total of these differences is +0.65, so the final bill must have a value that is $0.65 lower than the average.
The bill for the 6th month is $54.35.
_____
Check
The average of the bills for 6 months is;
(57.60 +60 +53.25 +50.75 +54.05 +54.35)/6 = 330/6 = 55
Answer:
x=-4.992 and x=-0.434
Step-by-step explanation:
we have

we can divide the equation above into two equations
so
----> equation A
----> equation B
Solve by graphing
The solutions of the system are the x-coordinates of the intersection points both graphs
using a graphing tool
The solutions are x=-4.992 and x=-0.434

Answer:
Step-by-step explanation:
5x + 2y = - 2
2y = - 5x - 2
y =
x - 1
Answer:
s = 65/3 pi
Step-by-step explanation:
The length of the intercepted arc is given by the formula
s =r*theta when theta is given in radians
r = 13
theta = 5 pi/3
Substituting what we know
s = 13 * 5 pi/3
s = 65/3 pi
Since we want an exact answer, we have to leave it in terms of pi and as a fraction
Tony's dorm is 7.5 miles far from the library.
Step-by-step explanation:
Given points are;
(4,0) and (12,6)

Using point distance formula;
Distance = 

One unit represents 0.75 miles, therefore,
10 units = 0.75*10 = 7.5 miles
Tony's dorm is 7.5 miles far from the library.
