The answer is C, 25% increase. To find the increase, subtract starting value (780) from the final value (975). It equals out to be 195. Divide 195 by the starting value which turns out to be 0.25. Then, multiply 0.25 by 100 which equals out to be 25.

Answer:
To the nearest hundredth, the rate of flow will be 75.38 mm/hr
Step-by-step explanation:
Here in this case, we are to express the rate at which the water flow and round it up to the nearest hundredth.
We are told that water flows through the pipe at a rate of 490 mm every 6.5 hours.
Now, the rate will be 490/6.5 = 75.384615384615 mm/hr
Rounding this value to the nearest hundredth, we have 75.38 mm/hr
Khalid and Sue's Height together is 126 Inches. The difference is 6 inches, so therefore you subtract 6 from the total getting you 120 Inches. You do this with all of the problems for example: The first one. Sue is 72 inches and Khalid is 54. Add them together and subtract them by 6 to get your final answer. Please DO NOT quote me on this lol. This is how I read the question. I think this is right but I am not absolutely 100% sure. Hope this helps.
