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.

A line with slope 1/2 passes through the point (8, -1). What is the equation of this line?
OverLord2011 [107]
The equation would be: Y= 1/2x-1. Reasoning: Our equation format is Y=mx+b. Consider y to just be there for the mean time, but mx is where we insert our slope. We already know what our slope is in this equation (1/2) so that’s what we’ll insert, changing mx to 1/2x. B is where we put our Y. In this coordinate, our Y is -1 (keep in mind that a coordinate is set up as so: (x,y). Insert all our numbers to replace the variables and you get Y=1/2x-1

Cherie bought 2 cupcakes and got $12.50 back.Sonya bought 4 cupcakes and got $5.00 back.If they each paid with the same amount o
blondinia [14]

Answer:

The cost of 1 cupcake  = $3.75.

Step-by-step explanation:

Let the cost of one cupcake = $ x.00

Now, the money spent by Cherie on 2 cupcakes = 2 ($x.00) = $2x

Also, the money spent by Sonya on 4 cupcakes = 4 ($x.00)  = $4x

Now, according to the question:

$2x  + $12.50  = $4x  + $5.00

or, 2x + 12.50 = 4x + 5

⇒ 4x - 2x = 12.50 - 5

or, 2x = 7.50

or, x  = 7.50/2 = 3.75

or, x = $3.75

Hence, the cost of 1 cupcake  = $3.75.
