We can express an equation to find the fraction of the catering order that is sandwiches or salads by summing up the fractions of the sandwiches and the salads, in this case, the fraction of the sandwiches is 5/12 and the fraction of the salads is 2/12, then the equation looks like this:
c = 5/12 + 2/12, option B is the correct answer
Y = 4/5x + 30
4/5 because the slope is 4 up, 5 right. 30 is the y-int
Answer:
The answer is below
Step-by-step explanation:
a) The integral
means the total change in level of water in inches from 1 am to 10 am. That is the water level change measured in inches between 1 am and 10 am
b) 7 pm is represented as t = 19 hours, while midnight is represented as t = 24 hours, hence the water level change between 7 pm and midnight is:

c) Using casio calculator to evaluate the integral gives:
= 2.54 inches
D) The total daily change in water level =
= 0.35 inches
