Samuel spent 2 7/12 hours studying in the morning and 1 7/8 hours in the evening. How much longer did Samuel study in the morning?

42.5 minutes

Step-by-step explanation:

7/12 of an hour equals 35 minutes, so

2 7/12 hours = 60 + 60 + 35 = 155 minutes

7/8 of an hour equals 52.5 minutes, so

1 7/8 hours = 60 + 52.5 = 112.5 minutes

155 - 112.5 = 42.5 minutes

Samuel spent 42.5 more minutes studying in the morning. *I don’t know if your answer is supposed to be rounded up, if so it would be 43 minutes.

I hope this helps!

the answer would be d.

step-by-step explanation:

move all variables to the left side and all constants to the right side

(x−3)^2+(y−1)^2=16

this is the form of a circle. use this form to determine the center and radius of the circle.

( x − h ) 2 + ( y − k ) 2 = r 2

match the values in this circle to those of the standard form. the variable   r   represents the radius of the circle,   h   represents the x-offset from the origin, and   k   represents the y-offset from origin.

r = 4

h = 3

k = 1

the center of the circle is found at   ( h , k ) .

center:   ( 3 , 1 )

these values represent the important values for graphing and analyzing a circle.

center:   ( 3 , 1 ).

radius:   4
