so, Buttons Etc. sells buttons at $50 + 1.10 for each button, and Logos sells buttons fro $40 + 1.10 for each button.

A)

let's say that "b" is the amount of buttons Crusader Pep Club is going to buy.

let's take a look at a few buttons prices for Buttons Etc.

1 button.................. 50 + 1.10(1)

2 buttons............... 50 + 1.10(2)

3 buttons............... 50 + 1.10(2)

4 buttons............... 50 + 1.10(4)

5 buttons............... 50 + 1.10(5)

b buttons............... 50 + 1.10(b)

let's take a look at the prices at Logos

1 button.................. 40 + 1.10(1)

2 buttons............... 40 + 1.10(2)

3 buttons............... 40 + 1.10(2)

4 buttons............... 40 + 1.10(4)

5 buttons............... 40 + 1.10(5)

b buttons............... 40 + 1.10(b)

B)

when both companies are the same price, the price equation for Buttons Etc equals the price equation for Logos, namely 50+1.10b = 40 + 1.10b.

when does that occur?  At how many buttons?

50+1.10b = 40 + 1.10b

10 ≠ 0


from the system of equations, we end  up with 10 = 0, which is not true of course 10 ≠ 0, which is another way to say there's no solution to the system, namely, the equations' graphs never touch each other.

if you recall the slope-intercept form, notice, both have the same slope, so the lines are parallel, and the y-intercept differs, so they never touch each other.

so, since there's no solution, the companies Buttons Etc and Logos sales of buttons will never yield the same price, the prices will always differ for the same amount of buttons sold.

HURRICANES A category 3 hurricane reaches speeds up to 20.88 kilometers per hour. The distance from Cuba to Key West is 145 kilo
White raven [17]
Let us assume that the time taken by the category 3 hurricane to travel from Cuba to Key West = X minutes
Speed of the category 3 hurricane is given as 20.88 km/hr
So the category 3 hurricane can travel 20.88 km in 1 hour.
The distance between Cuba and Key West = 145 km
Then
20.88 km is travelled by the category 3 hurricane in = 60 minutes
145 km from Cuba to Key west is travelled by the category 3 hurricane in = X minutes
So,
X = [(145 * 60)/20.88] minutes
   = 416.66 minutes
   = 17 hours and 36 minutes
Time taken by the category 3 hurricane to reach Key West from Cuba is 17 hours and 36 minutes.

How many cylindrical can of bottles 12 cm high and with 6 cm diameter could be filled from a tank containing 125 liters of deter
Orlov [11]

Answer:

368 cans.

Step-by-step explanation:

Volume of 1 can = π r^2 h.

Here h (height) = 12 and r (radius) = 1/2 * 6 = 3 cm.

So V =  π * 3^2 * 12

= 108π cm^3.

The tank hold 125 liters

=  125,000 cm^3, so:

Number of cans that could be filled = 125000/ 108 π

= 368.4.
