An enclosed area is designed using one existing wall, and 72m of fence material. What is the maximum area of the enclosure?
Answer:
The maximum area possible is 648 squared meters.
Step-by-step explanation:
Let the length of the existing wall be [tex]\ell[/tex].
And let the width of the fence be [tex]w[/tex].
The area of the enclosure will be given by:
[tex]A=w\ell[/tex]
Since the area is bounded by one existing wall, the perimeter (the 72 meters of fencing material) will only be:
[tex]72=2w+\ell[/tex]
We want to maximize the area.
From the perimeter, we can subtract 2w from both sides to obtain:
[tex]\ell=72-2w[/tex]
Substituting this for our area formula, we acquire:
[tex]A=w(72-2w)[/tex]
This is now a quadratic. Recall that the maximum value of a quadratic always occurs at its vertex.
We can distribute:
[tex]A=-2w^2+72w[/tex]
Find the vertex of the quadratic. Using the vertex formula, we acquire that:
[tex]\displaystyle w=-\frac{b}{2a}=-\frac{(72)}{2(-2)}=18[/tex]
So, the maximum area is:
[tex]A=-2(18)^2+72(18)=648\text{ meters}^2[/tex]
Find the missing value in the table.
The answer would be 80. why? just basically add the x number by it's self and you get your answer.
like 5 +5 gets u 10 in the y axis
and 40+40 gets u 80 in the y axis.
for which would you draw a dashed boundary line a d shade to the left?
a) x⩽ -4
b) x ⩾ -4
c) x < -4
d) x > -4
Answer:
a) x⩽ -4
Step-by-step explanation:
This is because the required region is anything to the left of -4 that is x < -4. Now since x = -4 is inclusive, we have the inequality x ≤ -4.
We thus draw a dashed boundary line to represent the equality at the boundary for x ≤ -4.
Since that is done, we then shade to the left of the boundary line which is the required region of x ≤ -4.

Morgan surveyed 260 of the students in her school about their favorite color. 65% said their favorite color was red. How many students' favorite color was red?
Answer:
169 students
Step-by-step explanation:
From the above question:
Total number of students surveyed = 260
Percentage of students that their favorite colour is red = 65%
Hence: The number of students that their favorite color is red is calculated as:
= 65% × 260
= 65/100 × 260 students
= 169 students
The number of students that their favorite color is red is 169 students
what is 6x+7y=4x+4y6x+7y=4x+4y
we have
6x+7y=4x+4y
we figure out that
the solution is ----> (x,-4)
substitute the value of y=-4 in the equation
6x+7*(-4)=4x+4*(-4)
6x-28=4x-16
Combine like terms
6x-4x=28-16
2x=12
x=12/2
x=6
So the the missing value is x=6.

I recommend drawing out a number line. The negative numbers will increase in magnitude as you move from 0 and go to the left. The positive values increase as you expect when going from left to right.
So we'll have -8 to the left of -5 since -8 is smaller than -5. The value -8 is 8 spots to the left of 0; while -5 is 5 spots to the left of 0. The value 0 is at the center of the number line universe so to speak.
Why is the set {(3,6), (4,8), (5 , 10), (3, 1), (6, 12), (7, 10)} NOT a function?
A. The ordered pairs are not in ascending order.
B. The ordered pairs do not all follow the rule y = 2x.
С. 3 is mapped to both 1 and 6.
D. Both 5 and 7 are mapped to 10.

Carrie borrowed $800 dollars from her aunt at 8% interest per year. If she paid her a total of $448 in simple interest, how many years did it take her to pay her aunt back?
Answer:
13 years
Step-by-step explanation:
First we will have to see how much she owns her aunt:
800-448= 362
8% of 348 = 27.84
362 ÷ 27.84 = 13 years
