12 ounces are in 3/4 a pound.. and 16 ounces are in a pound.. so adding 16 and 10 gives you 26, which ends up with Karla's supplies weighing 4 pounds and 10 ounces all together.
Perimeter = 24
triangle perimeter = 2W + 2L
24= 2W + 2L
12 = W + L
L= 12-W
AREA = W*L
AREA = (W)(12-W)
A = 12W-W^2
maximum occurs when you take the derivative
d/dw=12-2w = 0
w=6
after this i think we can say 6 * 6 = 36 is the maximum area.. not to sure, havent done a problem like this in a while
hope this helps
or if we know what w=6 we can find L
L = 12-w which we still get 6<span />
Here is the inequality you are describing:
10x+4≤25
Where x is the "number" you are describing.
Tan = opp/adj
Opp of C = 36
Adj of C = 15
Tan = 36/15 simplified = 12/5
hope this helps :)
You should use this method
