All you have to do in order to solve for the length of the square, simply take the expression and divide each term in the equation by 4, since the perimeter equation is the result of the length of the side equation multiplied by 4.
The final solution would be C.
Answer:
50%
Step-by-step explanation:
10 kg of mixed nuts that contain 60% peanuts
60(10)
plus
15 kg of a different brand of mixed nuts. with x% peanuts
x(15)
=
That makes 25 kg with 54% peanuts
54(25)
--------------------------
Equation
60(10) + x(15) = 54(25)
600 + 15x = 1350
Subtract 600 from both sides
15x = 750
Diviede both sides by 15
x = 50
50%
12 months in a year
12months=1year
96000/1year=96000/12months, 8000/1month
so earns $8000 permonth
Answer:
Step-by-step explanation:
for the cylinder
27π = πr²h = πr²(2r) = 2πr³
for the sphere
V = (4/3)πr² = (2/3)(2πr³) = (2/3)27π
