so solve for "x", to see how much is the company paying for the purchase of 1 minute
now, they're plan to sell the minute for 8cents, how much is the profit?
that is, the difference from their cost of the cents to the planned selling price.
bear in mind, is 46,000,000 minutes, so whatever value you get for 1minute,
you need to multiply it for 46,000,000 to get the actual cost.
and the revenue from the sell of 8cents per minute, is of course, 8 * 46,000,000
profit = revenue - cost
The number of possible seats is an illustration of permutation
There are 1728 possible sitting arrangements
<h3>How to determine the number of seats</h3>
From the question, we have the following highlights:
- Chris can only take 1 seat (i.e. the central seat)
- Jo can take 2 seats (i.e. the seats adjacent the central seat)
- Alex, Barb and Dave can take 3! number of seats
- Eddie, Fred, and Gareth can take 3! number of seats on the right of Chris.
- The remaining 4 adults do not have preference, then they can seat in 4! ways
So, the number of sitting arrangement is:
Evaluate the product
Hence, there are 1728 possible sitting arrangements

12x/15-10x/15
=2x/15 is your answer
600×3.5%=21. As a result, there are 21 phones that likely to be defective. Hope it help!
Answer:
The answer to your question is below
Step-by-step explanation:
1.- 3x + 54 = 5x + 14
3x - 5x = 14 - 54
-2x = - 40
x = 20
2.- I can not see it
3.- Yes, they are paralleles
because 180° = 119 + 61 = 180°
4.-
180° - 82 - 31 = 67°
180° - 67 - 98 = 15°
q = 15°
5.- 100 - x + 30 + 4x + 7x = 180
10x = 180 - 100 - 30
10x = 50°
x = 5
7x = y
y = 7(5)
y = 35°
6.-
55 + 4x + 2x - 5 = 180
6x = 180 - 50
6x = 130
x = 21.7°
7.-
slope = (1 - 2) / (3 - 0)
m = -1 / 3
( y + 1 ) = -1/3(x - 0)
8.-
9.-
slope = 3/7
P (-14 , -3)
( y + 3) = 3/7(x + 14)
10.-
Point (3,2)
A (2, 10)
B (4, 7)
slope = (7 - 10) / (4 - 2)
m = -3/2
New slope = 2/3
(y - 2) = 2/3(x - 3)
