Answer:
Only A
Step-by-step explanation:
For A, the y coordinate does represent the total cost of electricity for 4 hours. If you see the corresponding numbers on the chart, they both work. As for B, I used a proportional relationship with A to calculate if B works. Work: $120/4 hours. Divide both sides by 4 and u get $30 per hour, which means B is incorrect. C is incorrect because the answer is A.
Answer:
g = 8. (Answer C)
Step-by-step explanation:

24 gallons per hour
Step-by-step explanation:
Connor filled his 150-gallon pool with water in 6.25, to find out how many gallons per hour he used, we have to divide the amount of gallons into every hour. Therefore:
150/6.25
24 gallons per hour.
I personally would use the Pythagorean theorem over distance because it is a lot simpler
