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
copy and past the below 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
copy and past the above :
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°

Answers
Answer:
[tex]4 \frac{1}{9}x[/tex] + [tex]12\frac{1}{3}[/tex] = 0
Step-by-step explanation:
Based on 2x - 9y - 12 = 0
-9y = 12 - 2x
9y = -12 + 2x
y = [tex]-1\frac{1}{3} + \frac{2}{9} x[/tex]
Therefore...
5x - 4y + 7 = 0
5x - 4([tex]-1\frac{1}{3} + \frac{2}{9} x[/tex]) + 7 = 0
5x + [tex]5\frac{1}{3}[/tex] - [tex]\frac{8}{9} x[/tex] + 7 = 0

Answer:
13 5/8 Or 13.625
Explanation:
• Let's start with 1/4. There are five days that has the amount of 1/4 of rainfall.
So we have to add all five of the 1/4 or just multiply:
1/4 x 5 = 5/4
• Now for the 3/8. There are twelve days that has that amount of rainfall.
3/8 x 12 = 36/8
· For 1/2. There are five days.
1/2 x 5 = 5/2
· For 5/8. There's five days.
5/8 x 5 = 25/8
• Lastly for 3/4. There is three days.
3/4 x 3 = 9/4
• Now we add all of the amount together: 5/4 + 36/8 + 5/2 + 25/8 + 9/4
- To add, we have to find the Least Common Denominator (LCD), which is 8.
So we have to make all of the fractions into a denominator of 8 by multiplying:
5/4 –> 10/8 (Multiply by 2)
36/8 (Stays the same, already have the denominator of 8)
5/2 –> 20/8 (Multiply by 4)
25/8 (Stays the same, already have the denominator of 8)
9/4 –> 18/8 (Multiply by 2)
• Now add:
10/8 + 36/8 + 20/8 + 25/8 + 18/8 = 109/8
109/8 = 13 5/8
Or as decimal form: 13.625

The confidence interval of eggs chickens from this poultry farm lay in one month will be (22.96, 26.64). Then the correct option is C.
What is the confidence interval of the sample?If the sample size is given to be n < 30, then for finding the confidence interval for mean of population from this small sample, we use t-statistic.
Let the sample mean given as μ and
The sample standard deviation σ, and
The sample size = n, and
Then the heights would be outside the 90% confidence interval will be
For 90% confidence interval, we have z = 1.645
⇒ μ ± z (σ/√n)

A wind turbine has three equally spaced blades that are each 131 feet long. What is the measure of the arc between any two blades?
Answers
Answer:
274.23 feet
Step-by-step explanation:
From the question,
The measure of the arc between any two blades (s) = 2πrΦ/360
s = 2πrΦ/360................... Equation 1
Where Ф = angle formed betwen two blades, r = length of each blade.
Given: Ф = 360/3 (the three blades are equally spaced) = 120°, r = 131 feet.
Constant: π = 3.14
Substitute these values into equation 1
s = (2×3.14×131×120)/360
s = 274.23 feet.
Hence, the measure of the arc between any two blades is given = 274.23 feet

strawberry pies__

No links please!
Thank you
Answers
Answer:
2 strawberry
4 blackberry
Step-by-step explanation:
s = number of strawberry pies
b = number of blackberry pies
s + b = 6, then s = 6 - b
9s + 8b = 50
substitute for s:
9(6 - b) + 8b = 50
54 - 9b + 8b = 50
54 - b = 50
subtract 54 from each side of the equation:
-b = -4
multiple both side by -1:
b = 4
s = 6 - 4 = 2
How many solutions does the system of equations below have?

Answers
Answer:
C
Step-by-step explanation:
Answer:
C: none
Step-by-step explanation:
Here we have two separate functions named 'y.' Eliminate 'y' temporarily by equating these functions together:
x + 2 = y = x - 1
Subtracting x from both sides, we get:
0 + 2 = y = 0 - 1, or
2 = -1
This is never true, so C is the correct answer: NO solutions.
An easier way in which to do this problem is to visualize the graphs of
y = x + 2 and y = x - 1. The graphs are parallel straight lines; they never intersect, and therefore we can conclude "no solution."
Ike's igloo sold 501 ice cream cones today.They sold half as many chocolate ice cream cone as vanilla ones. How many of each were sold?
Answers
Answer:
Chocolate cones = x = 167 cones
Vanilla cones = y = 334 cones
Step-by-step explanation:
Let
The number of Chocolate cones = x
Vanilla cones = y
Ike's igloo sold 501 ice cream cones today.
x + y = 501.... Equation 1
They sold half as many chocolate ice cream cone as vanilla ones.
x = 1/2y
x = y/2
Cross multiply
y = 2x
We substitute 2x for y in Equation 1
x + 2x = 501
3x = 501
x = 501/3
x = 167
Solving for y
y = 2x
y = 2 × 167
y = 334
Therefore,
The number of
Chocolate cones = x = 167 cones
Vanilla cones = y = 334 cones
