The formula to get the correct answer to question is this:
1.) To get the total cost of goods bought:
((100 key chains) x ($0.25 purchasing cost)) + ($8 shipping rate) = $33
Which means each key chain essentially costs $0.33 each
2.) To get the number of units they should sell to make profit:
Breakeven = Costs/Price meaning $33/$2 = 16.5
They should sell 16.5 units to make a profit.
The atmospheric pressure is 14 lb/s^2 at sea level is the answer.
Answer:
There are 1,039,584 ways in which this can be done.
Step-by-step explanation:
Total number of black marbles = 17
Total number of blue marbles = 9
The number black marbles to be chosen = 6
The number blue marbles to be chosen = 3
So, we have to choose 6 black from 17 black marbles.
and to choose 3 blue from 9 blue marbles.
So, the number if possible ways to do it :
Now, solving , we get:
solving , we get:
Hence, there are 1,039,584 ways in which this can be done.
Answer:
Starting position of mine shaft is = 10m above ground
but,
it moves in opposite direction so it travels the distance (-350 m ) below the ground.
Total distance covered by mine shaft = 10m - (-350m)
= 10 + 350
= 360m
Now, taken to cover a distance of 6m by it = 1 minute
Time taken to cover a distance of 1m by it = \frac{1}{6\ }\min
Therefore, tie taken to a cover a distance of 360m = \frac{1}{6}\times\ 360\ =\ 60\ \min\ \
60 minutes = 1 hour
thus, in one hour the mine shraft reaches = 350 below the ground

Answer:
Equation: y = 65x
Randomly pick a x and y value and plug into above equation, if they don't equal then the x and y you've picked cannot be on this table.
Step-by-step explanation:
Pick any two points to find slope, let's got with (3, 195) and (4, 260):
slope m = (y₂- y₁) / (x₂ - x₁)
= (260 - 195) / (4 - 3)
= 65 / 1
m = 65
Find y-intercept by using m from above and another point from your table, let's go with (5, 325):
y = mx + b
325 = 65(5) + b
325 = 325 + b
b = 0
Use m and b to form equation of line:
y = mx + b
y = 65x + 0
y = 65x
Check:
point (3, 195): 195 = 65(3) ====> 195 = 195
point (4, 260): 260 = 65(4) ====> 260 = 260
point (5, 325): 325 = 65(5) ====> 325 = 325
point (6, 390): 390 = 65(6) ====> 390 = 390
Example of a point that doesn't belong on table:
point (8, 500): 500 = 65(8) ====> 500 ≠ 520
