Answer:
10. A) 120°
11. D) 40°
12. D) 54°
13. A) 101°
Step-by-step explanation:
The applicable rules of angles and arcs are ...
- the whole is the sum of the parts
- arcs of a circle total 360°
- an inscribed angle intercepts an arc of twice its measure
__
10) Angles C and L intercept the same arc (DE) so will have the same measure.
15x = 16x -4
4 = x . . . . . . . . add 4-15x
arc DE = 2(15x) = 30(4) = 120 . . . degrees
__
11) Arc VW is twice the measure of angle X, so ...
9x +8 = 2(5x)
8 = x . . . . . . . . . subtract 9x
∠VXW = 5x = 5(8) = 40 . . . degrees
__
12) Arc EFG is twice the measure of angle W, so ...
70° +FG = 2(88°)
FG = 106° . . . . . . . . . subtract 70°
Arc FGW is twice the measure of angle E, so ...
106° +GW = 2(80°)
GW = 54° . . . . . . . . . . subtract 106°
__
13) Arc ST is twice the measure of angle R. The sum of arcs is 360°.
RS +ST +TR = 360°
119° +2(70°) +TR = 360°
TR = 101° . . . . . . . . subtract 259°
Answer:
0.408 hour / device
Step-by-step explanation:
As we know The army contract was for 4,707 devices that were produced by 16 workers which means 1 worker can produce: 
≈294 devices in 3 weeks.
<=> 294 devices= 3*40 hours
<=> 294 devices = 120 hours
<=> 1 device = 120/294 = 20/49 ≈ 0.408 hour
So it takes 0.408 hour for a worker to finish producing 1 devicein the army contract
Answer:
y=2/3x+4
Step-by-step explanation:
2/3 is the slope and 4 is the y int
So base on your question where there is a set of line graph in the choices and what could be the perfect graph that could have or be fit with this sequences 1, 2.5, 4, 5.5, 7. So base on your data i conclude that the slope of the graph is 1.5 and you just need to graph it and its a slanting line that has a slope of 1.5
