Hello from MrBillDoesMath!
Answer:
One example is 52 and 54. They are between 50 and 60 and have the factor 2 in common
Discussion:
Consider the numbers between 50 and 60:
51, 52, 53, 54, 55, 56, 57, 58, 59
53 and 59 are primes so they don't have any factors in common and we can focus on the other numbers in the range.
Consider 52. It's even so is divisible by 2 as are 54, 56, 58. So 52 and 54 , for example, are are two number between 50 and 60 that have the factor 2 in common
Even number are visible by 2. Let's look for numbers visible by 3. How about 54 ( = 18 *3) and 57 ( = 19*3)? That works so its looks like there are many answers to this question.
Thank you,
MrB

hope this helps you ;)
Part 1
Let:
y be the total cost
x be the number of tickets
a be fair admission
Since the fair charges $1.25 per ticket, the equation of the line would look like:
y = 1.25x + a
Since Johnny spent $43.75 and bought 25 tickets, we find a by replacing y with 43.75 and x with 25:
43.75 = 1.25×25 + a
Now solve for a
43.75 = 31.25 + a
43.75 - 31.25 = a
a = 12.50
Going back to the first equation:
y = 1.25x + 12.50
Part 2:
a) Let (9,8) be (x1,y1) and (4,-12) be (x2,y2)
The formula for slope is:
b) For the point-slope equation, I'll use (9,8)
Using the formula:
c) For the slope-intercept form, we solve for y in the point-slope formula:
Answer:
2 pi*r^2 + 2 * pi *r * h
Step-by-step explanation:
I will assume that you are looking for surface area
We need to find the area of the top and the bottom, which is the area of a circle
top: pi * r^2
Bottom: pi r^2
Then the side which is the circumference times the height ( it is a rectangle)
side: 2 * pi *r * h
Add them together to get the surface area
SA = pi * r^2 + pi * r^2 + 2 * pi *r * h
= 2 pi*r^2 + 2 * pi *r * h
