Cd has endpoints c(6,-8) and d(-4,10) on a coordinate plane. what are the coordinates of the midpoint cd

The required midpoints are ( 1,  1 ).

Step-by-step explanation:

Given that the endpoints are C( 6, -8) and D ( -4, 10)-

As we know that-

If a line segment AB is with endpoints ( ) and  ( ) then the mid points C are-  

C = (   ,  )

Here,

C( 6, -8) and D ( -4, 10)-

then the midpoints C are-

C = (  ,

C= ( 2/2 , 2/2 )

C = ( 1, 1 )

Hence the required midpoints are ( 1, 1 ).

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. : )

the answer is 40.
