Answer:
Step-by-step explanation:
11) strategy: since they tell us. indirectly, that the length of JK is the same as LM then we can set those two equal, solve for X and then.. when we have X we can figure out the lenght of JK and LM and then just divide that by 2 go get PK ( :0 Player Killer ??? no , not that PK)
solve JK and LM
3x + 23 =9x-19
42 = 6x
7 = x
now that we know x = 7 plug it into either equation to come up with the length of JK or LM . I'll pick JK just b/c it was 1st
3(7) + 23 = JK
21+23 = JK
44 = JK
now take half of 1/2*JK= 22 that is PK ( are you sure that 's not player killer?)
PK = 22
12) strategy: set the two arcs BG and GC equal and solve for X, then plug x into either equation and the multiply the answer by 2 to find arc AB
9x-20 = 5x + 28
4x = 48
X = 12
9(12) -20 = BG
88 = BG
2*88 + AB
176 = AB
13) done
14) strategy: find the angle at L, and that will also be the arc of MK
<em>copy and past the below</em> helpful trig functions into your computer
Use SOH CAH TOA to recall how the trig functions fit on a triangle
SOH: Sin(Ф)= Opp / Hyp
CAH: Cos(Ф)= Adj / Hyp
TOA: Tan(Ф) = Opp / Adj
<em>copy and past the above</em> :
use which ever trig function you want , we have all the sides of the triangle, I'll use CAH
Cos(Ф) = 9/15
Ф = arcCos(9/15)
Ф = 53.13010°
arc MK = 53.13010°
15) strategy: arc JK is just 2 times MK
2*MK = 106.26020°
arc MK = 106.26020°
16) find arc JPK strategy: JPK is just the remaining part of a full circle of 360 - MK = 253.7397°
arc JPK = 253.7397°

Answer:
<em>It takes them 1.875 hours.</em>
<em></em>
<em>Step-by-step explanation:</em>
<em></em>
<em>Here, the job is cleaning the house.</em>
<em></em>
<em>Mom does 1 job in 3 hours.</em>
<em></em>
<em>In 1 hour, mom does 1/3 of the job.</em>
<em></em>
<em>Dad does 1 job in 5 hours.</em>
<em></em>
<em>In 1 hour, dad does 1/5 of the job.</em>
<em></em>
<em>Mom and dad working together do the job in x hours.</em>
<em></em>
<em>In 1 hour, mom and dad together do 1/x of the job.</em>
<em></em>
<em>1/3 + 1/5 = 1/x</em>
<em></em>
<em>5/15 + 3/15 = 1/x</em>
<em></em>
<em>8/15 = 1/x</em>
<em></em>
<em>8x = 15</em>
<em></em>
<em>x = 15/8 = 1.875</em>
<em></em>
<em>Answer: It takes them 1.875 hours.</em>

Answer:
C.
Step-by-step explanation:
Jack's rate = 28/2 = 14 boxes/hour
Walter's rate = 36/3 = 12 boxes/hour
Combined rate = 14 + 12
= 26 boxes/hour
26 = 65/t
26t = 65
