Use the table to determine whether the relationship is proportional. If so, write an equation for the relationship. Tell what ea
Neporo4naja [7]

Answer:

y = 25x, proportional relationship

Step-by-step explanation:

Let "x" = number of hours read (replace with "h" if that's the variable your teacher wants)

Let "y" = number of pages read (you can use any other variables if you want)

Let's first calculate the slope using \frac{y_{1} - y_{2}}{x_{1} - x_{2}} with any two points, I'm going to use  (2, 50) and (3, 75):

\frac{y_{1} - y_{2}}{x_{1} - x_{2}} = \frac{50 - 75}{2 - 3} = \frac{-25}{-1} = 25

Our slope is m = 25.

Now we can use the point-slope form y-y_{1} = m(x-x_{1})  with our slope and any point (I'll use (2, 50)) to figure out the equation:

y-y_{1} = m(x-x_{1}) \\ y-50 = 25(x-2)

Simplify:

y-50 = 25(x-2)\\y-50 = 25 x -50\\ y = 25x

Since the slope is positive, the relationship is proportional.

lakkis [162]

Answer:

5 hrs  19.57 Minutes will be taken to prepare 1575 Bags by Ashley & her 4 friends if Ashley take 2/3 minute to prepare a bag & her each friend takes 75% Longer

Step-by-step explanation:

Ashley Takes  2/3  minute to prepare a bag

=> ashley prepare bag in 1 minute = 3/2  

Her friends takes 75%  Longer to prepare a bag

time taken by her friends =  2/3  + (75/100)(2/3)

= (2/3)( 1  + 3/4)

= (2/3)(7/4)

= 7/6  Minutes

Her one friend prepare bag in 1 minute =  6/7

Bag prepared by Ashley & her 4 friend in 1 Minute

=  3/2  +  4*6/7

=  (21 + 48)/14

= 69/14  Bag

69/14   Bag prepared in 1 minute

1 Bag prepared in    14/69   minutes

1575  bags prepared  in   1575  * 14/69

= 319.57 minutes

= 5 hrs  19.57 Minutes
