Answer:
Step-by-step explanation:
Let the length of the fence = x
Let the width of the fence = y
Recall that the perimeter of a rectangle is calculated by 2(L+B) , but the farmer is using the side of the barn on one side of the rectangle , so the perimeter equation is
x + 2y = 48
Area = xy
If we substitute the perimeter equation so that the area is only in terms of y.
Area = (48 - 2y)y
Area = 48y - 2
Now just find the vertex of the parabola
Area = -2 + 48y
A = -2 + 48
Differentiate A with respect to y
= -4y + 48
equate it to zero , we have
-4y + 48 = 0
4y = 48
y = 12
Substitute y = 12 into equation 1, we have
x = 48 - 2y
x = 48 - 2(12)
x = 48 - 24
x = 24
Therefore the dimensions of the garden are 24 by 12
The maximum area is 288 square unit
The two numbers are 30 and 36. I know this because when I did 10 and 16, I realized that if I went up 10 for each number, the sum would go up by 20. So I did 20 and 26, and got 46. Then I did 30 and 36, and the sum was 66.
Hope this helps!
Answer:
12.5%
Step-by-step explanation:
There are two types of spinners here and the outcome of them is independent. That means
P(odd number,C) = P(odd number) * P(C)
There are two odd numbers out of four numbers in the first spinner. The chance of odd number will be:
P(odd) = 2/(2+2)= 1/2= 50%
There are four letters and the desired outcome is C. The chance for C will be:
P(C)= 1/4= 25%
Then the chance will be:
P(odd number,C) = P(odd number) * P(C)
P(odd number,C) =50% * 25% = 12.5%
