Step-by-step explanation:
11) Probability of Black is 1/4
12) P of not orange is 3/4
13) P of blue or black is 1/2
this should be pretty easy for you, why is it tough? don't say .. " it just is" say what makes it tough. I'm curious why this is difficult. :?
Let x = length and y = width
You would have 2 lengths, so 2x and 3 widths, so 3y
Those need to equal total length of fence:
2x + 3y = 1200
The 3 widths would equal total fence minus the 2 lengths:
3Y = 1200-2x
Solve for y: y = 400 -2/3x
Area = length x width = xy. Replace y :
Area = x(400-2/3x) = 400x-2/3x^2
Differentiate:
400-4x/3 =0
4x/3 = 400
4x = 1200
X = 300
Y = 400-2/3(300) = 200
The dimension would be 300 ft x 200 ft
9/11 is the answer because 1 and 1/2 x 6 is 9
Answer:
27%
Step-by-step explanation:
Decrease= 15-11
=4
Percentage=4÷15
=0.266666667
=26.667%
~27%
5x and -8x are like terms. 6 is not a variable. 5 is the coefficient of the term 5x. X is not the constant.
