D) 88ft/minute
I NEED HELP ASAP!!!!! PPPPPPPPPLLLLLLLLEEEEEEEEEAAAAAAAAASSSSSSSSSSEEEEEEEE!!!!!

Answers

Answer: A) 264ft/minute

Step-by-step explanation:

1. Based on the information given in the problem, the speed of the track runner was 3 miles per hour ( $3(mi)/(h)$ ).

2. If you want to know the speed of the track runner in feet per minute, you need to apply the following proccedure:

$(3(mi)/(h))((5280ft)/(1mi))((1h)/(60min))=((3)(5280))/(60)=264(ft)/(min)$

3. Therefore, the answer is the option A.

the correct answer is A

Identify the independent and dependent variables. Eman is conducting an experiment to see how much sugar will dissolve in water as the temperature of the water is increased.

A.The independent variable is the temperature of the water, and the dependent variable is the amount of sugar dissolved.

B.The independent variable is the amount of sugar dissolved, and the dependent variable is the temperature of the water.

Answers

The correct answer is A. The independent variable is the temperature of the water, and the dependent variable is the amount of sugar dissolved. The independent variable is the one that isn't affected by any of the other variables. The dependent variable is the one being studied, measured, and affected in the experiment. Obviously, Eman wants to measure the amount of sugar that dissolves in water.
