- 239600
Answer:
57
Step-by-step explanation:
a The center of the hexagon and of the circle are the same point. Also length of one side of the hexagon = 90/6 = 15 units.
If we join each vertex of the hexagon to the center then we get 6 equilateral triangles (because internal angle of reg hexagon = 120 and vertex angles of the triangles = 60) so the radius = length of side of hexagon = 15 units (answer)
b Area = pi * 15^2 = 706.9 units^2 to nearest tenth. Answer
Answer:
g(7) = 16
Step-by-step explanation:
The domain definitions in this piecewise function tell you that the third (bottom) piece applies when x=7.
g(7) = (7+1)(7-5) = (8)(2)
g(7) = 16
Answer:
- a) j+c=310; j-c=40
- b) (j, c) = (175, 135)
- see attached
- Jose earned $175; Camden earned $135
Step-by-step explanation:
Let j and c represent Jose's and Camden's earnings, respectively.
(a) One equation can be written for the total; another for the difference:
j + c = 310 . . . . their total earnings
j - c = 40 . . . . . the difference in their earnings
__
(b) It is convenient to add these two equations to eliminate c:
(j +c) +(j -c) = (310) +(40)
2j = 350
j = 175
Then c can be found as ...
c = j -40 = 175 -40 = 135
The solution is (j, c) = (175, 135).
__
(c) Using x for j, and y for c, we can use Desmos to graph the equations. The result is attached.
__
(d) Jose earned $175 over the summer; Camden earned $135.
