James takes 75 minutes to complete a writing assignment, and 15 minutes to complete a science assignment. James is required
to spend more than 300 minutes on his assignments. According to his schedule, he can complete at most 20 assignments this
week
Which system of inequalities can be used to determine the number of writing assignments (w) and the number of science
assignments (s) James can complete this week?
OA. 15w + 755 < 300
w + s < 20
OB. 75w + 15s > 300
w + s > 20
C.
75w + 15s > 300
w + s < 20
OD. 15W + 755 > 300

256π units²   (answer b)

step-by-step explanation:

the formula for the surface area of a sphere of radius r

is             a = 4πr²

and so, if r = 8 units, then the surface area is:

a = 4π(8 units)² = 256π units²   (answer b)

complete the steps to find the area of the trapezoid.

area of rectangle = 256   square units

area of triangle 1 = 24  square units

area of triangle 2 = 16  square units

area of triangle 3 =   96 square units

area of trapezoid = 120  square units

step-by-step explanation:

answer: -2+√x,-2-√x

i hope this , i don't know if you're looking for a pair or not.

a. is correct
