Zigmanuir [339]

Answer:

2:25pm

Step-by-step explanation:

The time given is 5pm to catch the train back to school;

Amount of time for the tour  = 1hr 45min

                                               = 105min

Amount of time at gift shop  = 30min

Amount of time to save  = 20min

 Total time = 105min + 30min + 20min  = 155min

So;

Total time  = 2hr 35min

So;

        5pm - 2hr 35min  = 2:25pm

Kelli's mom takes a 520 mg does of aspirin. Each hour, the amount of aspirin in a person's body system decreases by about 22%. A
morpeh [17]

Answer:

we can write an equation wich describes the amount of aspirin in her system in respect to the hours (x)

a(x) = 520 * 0.78^x

78% is what's left on respect to one hour before and the "to the power of x" part describes how often we multiply/how many hours have passed

actually, if you haven't learned a better method yet, you could just grab your calculator, and type in 520 * 0,78

calculate it

then repeat multiplying the last answer till you go just below 80. the number of steps is the number of full hours passed.

this would take 8 steps

do you need a more sophisticated method to nail it down to the minute?

got no clue how far you are with the whole topic yet.

anyways, hope this helps you :)
