Hello from MrBillDoesMath!
Answer:
12/5
Discussion:
Note that 10 is a common denominator of both denominators:
9/5 = (9*2)/(5*2) = 18/10
- ( -6/10) = + (6/10)
So the original problem is equivalent to
18/10 + 6/10 =
(18 +6)/10 =
24/10 =
(2*12)/ (2*5) => cancelling the common factor "2"
12/5 =
2 and 2 fifths =
22/5 (though this looks like (22)/5!)
Thank you,
MrB
Asuming that all the teams have the same skill levels the game will mostly be chance. The chance of winning will be 1/12 because they are 1 out of 12 teams.
Answer: 3
Step-by-step explanation: When you solve for x you get 2 so when you put that into the equation (2+1) you get 3. You solve for x but solving this equation (x+5) = (x+1) Hope this helps :)
Volume is given to be 4.5 m^3
v = length x width x height
v = lwh
want everything in one variable w
given that;
l = 2w
using volume...
h = 4.5 / lw
h = 4.5 / 2w^2
surface area = wl + 2hl + 2wh
sub for length and height
s = 2w^2 + 9/w + 4.5/w
s = 2w^2 + 13.5/w
derivative s
s' = 4w - 13.5/w^2
0 = 4w - 13.5/w^2
13.5/w^2 = 4w
13.5 = 4w^3
13.5/4 = w^3
3.375 = w^3
cube root
1.5 meters = w
then the length = 2(1.5) = 3 meters
height = 4.5/(3*1.5) = 1 meter
