On four consecutive​ days, a concert pianist practiced for 3 1/2 ​hours,
6 1/3​hours,
4 1/4 ​hours, and
5 1/6hours. Find the​ pianist's total practice time.

19 hours and 15 minutes

Step-by-step explanation:

if you add it up all together it equals to 19.25 hours but you would convert it into 19 hours and 15 minutes

g = (2, 2)

step-by-step explanation:

given the ratio is 1 : 1 then f is the midpoint of eg

let the coordinates of g = (x, y)

using the midpoint formula

(0 + x) = 1 ( multiply both sides by 2 )

0 + x = 2 ⇒ x = 2

similarly

(4 + y) = 3 ( multiply both sides by 2 )

4 + y = 6 ( subtract 4 from both sides )

y = 2

coordinates of g = (2, 2)

2nd one in the first row is correct
