Robin and jackson play rugby on the weekends. on saturday they played 3 1/2 hours. on sunday they played 3/4 of the time thye played on saturday. what was the total time they played over the weekend in minutes and in hours

The answer to your question is: 2 hours 20 minutes

Step-by-step explanation:

Data

Hours played on Saturday = 3 1/2

Hours played on Sunday = 3/4 of those of Saturday

Total time played = ?

Process

Convert mixed fractions to improper fractions

               3 1/2 = (6 + 1) / 2 = 7/2

Calcula 3/4 of 7/2

                               7 / 2 x 3 / 4 = 21 / 8

Now, get the sum of the hours

               7 / 2 + 21 / 8 =  (28 + 21) / 8 = 49/ 21 = 7 / 3 hours

              7/3 = 2 hours 20 minutes

f(x) = - 2/3x + 5; f(5/2)

substitute 5/2 in for x:

f(5/2) = -2/3(5/2) + 5

simplify the right side:

f(5/2) = -5/3 + 5

f(5/2) = 10/3

answer:

f(5/2) = 10/3

i hope this you!

answer: the correct option is d.

explanation:

it is given that the triangle j'k'l' shown on the grid below is a dilation of triangle jkl using the origin as the center of dilation.

from the given graph it is noticed that k(4,8) and k'(2,4). let origin is defined by o and scale factor is defined by k, then

    (1)

distance formula,

put these values in equation (1).

therefore scale factor is     and option d is correct.
