Answer:
(D) 120 degrees
Step-by-step explanation:
From the figure drawn, we have
∠ABC=60°
And ∠OAB=∠OCB=90° (angles made by tangent on the circle is 90°)
Thus, ∠AOC+∠OCB∠CBA+∠OAB=360° (Angles sum property of quadrilateral)



Therefore, the value of x is 
Hence, option D is correct.
Answer:
22°
Step-by-step explanation:
a right angle have 90°
So
x+68°=90°
=>x=90-68
=22°
Answer:
134.38
This value represents 134.38
Step-by-step explanation:
Find the mean.
950+620+545+810+775+1120+905+775=6500
6500/8=812.5
Subtract the mean of numbers.
950-812.5=137.5
812.5-620=192.5
812.5-545=267.5
812.5-810=2.5
812.5-775=37.5
1120-812.5=307.5
905-812.5=92.5
812.5-775=37.5
Find the mean.
137.5+192.5+267.5+2.5+37.5+307.5+92.5+37.5=1075
1075/8≈134.38
This means that 134.38 is $134.38
Answer:
50 what
Step-by-step explanation:
a. Write the cost function:: C(x) = 100x + 100,000 where x is number of guitars
---------------------------------
b. Write the revenue function:: R(x) = 300x where x is number of guitars
-----------------------
c. Find the profit function.
Profit = Revenue - Cost
P(x) = R(x) - C(x)
P(x) = [ R(x) ] - [ C(x) ]
P(x) = [ 300x ] - [ 100x+100,000 ]
P(x) = 300x - 100x-100,000
P(x) = 200x - 100,000
The break even point is when the profit is 0 dollars. You don't lose any money. And you don't gain any money.
Solve 125x - 100,000 = 0
125x = 100,000
x = 800 (# of guitars made and sold)
