Andre and Priya are tracking the number of steps they walk. Andre records that he can walk 6000 steps in 50 minutes. Priya write
Simora [160]

Andre walks more steps than Priya.

To find out who many steps each one of them walks in a week, we have to carry out different calculations starting with Andre.

                 Calculation for number of steps taken by Andre

Andre takes 6000 steps in 50 minutes. We can use this information to scale up his number of steps over a period of 5 hours(300 minutes.). The quickest way to do this calculation, is to notice that there are 6 different 50 minute segments in 300 minutes. This means that the number of steps taken in 5 hours is 6\times 6000=36000 steps.

Another way to do this calculations is to use proportions

6000=50\\x=300\\=>50x=300\times6000=1800000\\=>x=36000.

Andre takes 36000 steps that week.

                 Calculation for number of steps taken by Priya

The number of steps taken by Priya is given by the is given by the function y=118x where x is the time in minutes. Priya walks for a total of 5 hours or 300 minutes. We calculate the number of steps she takes as shown below,

y=118x\\y=118\times 300\\y=35400.

Priya takes a total of 35400 steps.

Since  36000 steps is greater than 35400 steps, we conclude that Andre walks more steps than Priya.

Princeton caught 42 fish this summer, which is 70% of the number of fish his friend Trenton caught.
Mashcka [7]
I hope you actually want to know the number of fishes caught by Trenton the friend of Princeton. Let us write down all the details that are given in the question. These details will help in answering the question.
Number of fishes caught by Princeton = 42
Let us assume the number of fishes caught by Trenton = x
Then
70x/100 = 42
7x/10 = 42
7x = 42 * 10
7x = 420
x = 420/7
  = 60
So the number of fishes caught by Trenton = 60.

Who's gonna answer my last math question??
iragen [17]
I would say A because every other question it shows the exact amount but since it says 20-29 you can’t really say the answer by looking at the graph unless you guess but that’s not what the question is saying it’s saying which question cannot be answered by looking at the graph and I would Say You cannot answer A by looking at the graph.


Sorry if I am wrong
