1.)cameron uses color film for 48out of every 72 photographs he takes. if he takes 156 photographs, how many will be on color film?
a.72
b.104
c.156
d.234
e.276

B. 104

Step-by-step explanation:

Since the problem gives an initial ratio of 48 out of 72, color to total photographs, we can set up a proportion, or equivalent ratios to solve for the amount of color film in 156 photographs:

cross-multiply: 72x = (48)(156)  or 72x = 7488

divide and solve: 72x/72 = 7488/72

x = 104 color film photographs

the red lines denote the population of the bacteria after 35 hours. that would be 2,409.24. the y-intercept is the blue line which is 800 because that is the starting point. the equation used to make the graph is 800(1.032)^h, where h is the number of hours.
