Answer:
10 minutes
Step-by-step explanation:
First off, you want to figure out how many photos it prints in one minute. 36 divided by 8 is 4.5. So you should add 4.5 to 36, which makes 40.5 in 9 minutes. Add another 4.5 and you get 45 which you should add another minute. That gives you 10 minutes.
Another way is to find how many per minute which would again be 4.5. 45 divided by 4.5 is 10. So once again, 10 minutes.
Answer:
15 x 8 = 120
Step-by-step explanation:
There are 15 tables and 8 people sit at each the number of people that would be able to go would be 120

The answer is

If P1 has coordinates (x1, y1) and P2 has coordinates (x2, y2), then the distance between the two points is given by [(x1 - x2)2 + (y1 - y2)2]½ or [(x2 - x1)2 + (y2 - y1)2]½ Using the same two points as above, the midpoint formula is M = [(x1 + x2)/2], [(y1 + y2)/2] If we wanted to find the slope of the line on which the two points lie, it would be given by: m = (y1 - y2)/(x1 - x2) or (y2 - y1)/(x2 - x1) Some quadratic equations can be easily factored, some cannot. For those cases we use the Quadratic Formula: If ax2 + bx + c = 0 then x = [-b ± (b2 - 4ac)½]/2a Notice that the Distance, Midpoint and Slope Formulas all refer to linear equations. The quadratic formula, as the name implies, is used to find roots of an equation in which the variable x is squared.
