Asap 99 points and ! find the midpoint of diagonal bd. figure abcd is shown. a is at negative 3, 2. b is at 0, 6. c is at 6, 6. d is at 3, 2. (1, 3.5) (1.5, 4) (2, 3.5) (2, 4)

(1.5, 4)

Step-by-step explanation:

A (-3,2)  B (0,6)  C (6,6)  D (3,2)

so mid-pt of BD is ((0+3)/2, (6+2)/2) = (1.5, 4)

she played for 18.75 hours.

step-by-step explanation:

if she played 2/4 of a hour on tuesday. and there is 60 minutes in an hour and 60 divided by 4 is 7.5. and she played 2/4 of an hour on thursday then again 60 divided by 4 is 7.5, you add 7.5+7.5=56.25. now you have to do 1/4 of an hour, it equals 3.75. now you have to add them all up. 3.75+7.5+7.5=18.75

i hope this and i hope you get it right. it took me a while to get this done for you. : )
