The area of a sphere: A = 4.π.R²

A= 5541.77 → 5541.77 = 4.π.R²

R² = (5541.77)/(4.π)
R² = 441; → R =√441; R = 21 cm

The German club is planning a ski trip.The club will pay $500 toward the trip, and each member going on the trip will pay $115.

Ivahew [28]

500+(x115)=2685

the 500 is the money the club is putting towards the trip. the x is the number of club members. the 115 is the cost each member will pay to go on the trip.

subtract 500 from each side leaving you with
(x115)=2185
divide each side by 115
x=19
there are 19 club members going on the trip.

A line passes through the point (-3,8) and has a slope of -7 . write an equation for this line

Alekssandra [29.7K]

Y - 8 = -7 (x + 3)
this is in point slope form

y - 8 = -7x - 21
y = -7x - 13
this is slope intercept form
