Answer:
62.8% OR 0.628
Step-by-step explanation:
11 hours playing video games
11 hours on the Internet
11 + 11 = 22
5 hours of free time each day
7 days in a week
5 x 7 = 35
22/35 hours are spent
That is 0.62857142857 or I just mathmatically rounded to 0.628
0.628 into a fraction is 62.8%
The volume of the cone will be given by:
Volume=1/3πr^2h
therefore the volume of our cone will be:
π=3.14
h=87
r=21/2
Volume=1/3*3.14*(21/2)^2*87
=10,039.365 cm^2
x - 2y = 5
-3x + 2y = 7
-----------------add
-2x = 12
x = 12/-2
x = -6
-3x + 2y = 7
-3(-6) + 2y = 7
18 + 2y = 7
2y = 7 - 18
2y = - 11
y = -11/2
solution is : (-6,-11/2)...x = -6 and y = -11/2
I can answer this for you its 4.8,2.6,and 2.3
