Formula of v. of sphere = (<span><span>4</span>π</span>r
)/3<span>
r = 3
pi = 3
(4 x 3 x </span>
)/3 = 113.1
Answer = 110cm
The answer would be, A) +$2 because he spend $12 but earned $14 so when you subtract 14 and 12 you get $2, which would be his profit
Let, Number of Hours in Library = x
Number of Hours in babysitting = y
Inequality would be: x + y = 30 ;
& 8x + 6y ≥ 200
b) Solving: Multiply first equation by 6,
6x + 6y ≥ 180
Subtract it from 2nd equation,
2x ≥ 20
x ≥ 10
Now, substitute it in 1st equation,
10 + y = 30
y = 20
Your Answer would be (10, 20)
x - value is lesser or equal to 10, so it would move to left (decreasing direction)!
Hope this helps!
X intercept = (-3, 0) (3, 0)
y int = (-2,0) (2,0)
