The area, A, in square feet, of the base of a rectangular storage bin in a warehouse is given by the function A(x) = -2x2+ 36x, where x is the width, in feet, of the storage bin.
Part B: The process of completing the square can be used to calculate the width, in feet, of the storage bin that gives a maximum area.
A(x) = -2x2 + 36x
A(x)= -2(x – 9)2 + ___
What is the missing value in the work shown?

The missing value is 162,
Option A is the correct answer.
What is a rectangle?A rectangle is a 2-D shape with length and width.
The length and width are different.
If the length and width are not different then it is a square.
The area of a rectangle is given as:
Area = Length x width
We have,
To complete the square for the function.
A(x) = -2x² + 36x,
We need to first factor out the coefficient of x², which is -2:
So,
A(x) = -2(x² - 18x)
Next,
We need to add and subtract a term that will allow us to factor the expression inside the parentheses into a perfect square.
To do this,
We need to take half of the coefficient of x, which is -18/2 = -9, square it, and then add and subtract the result.
So,
A(x) = -2(x² - 18x + 81 - 81)
Now,
We can rewrite the expression inside the parentheses as a perfect square.
A(x) = -2((x - 9)² - 81)
Finally, we can distribute the -2 and simplify.
A(x) = -2(x - 9)² + 162
So,
The missing value is 162,
Thus,
The missing value is 162,

Answer:
c) 193
Step-by-step explanation:
Sum of all the angles of the pentagon = 540
2x + 7 + x + x + 8 + 3x - 11 + x - 8 = 540
2x +x + x + 3x + x + 7 + 8 - 11 - 8 = 540
8x - 4 = 540
8x = 540 + 4
8x = 544
x = 544/8
x = 68°
∠V = 3x - 11

4/_ ‘ _/36
Which number goes into both boxes?
A) 6
B)9
C)12

Answer:
C) 12
Step-by-step explanation:
What you are trying to find is when 4/_ = _/36. The only number that will set these two ratios equal is 12. This is because 4/12 simplifies to 1/3, and 12/36 simplifies 1/3, meaning the two ratios are equivalent.

A total of 937 people attended the play.
Admission was $2.00 for adults and $0.75
for students. The total ticket sales
amounted to $1,109. How many students
and adults attended the school play?
First complete the equations below, where A
stands for Adults and S stands for Students.
2A + 0.75S = 1,109; A + S = 937
Now use the equations to find the number of
students and adults.
Students = [?]; Adults = []
Answer:
612 students and 325 adults
Step-by-step explanation:
I'll use substitution for this set of equations. I'll start with 2a + 0.75s = 1,109.
2a + 0.75s = 1,109
Subtract 0.75s from both sides.
2a = -0.75s + 1109
Divide both sides by 2.
a = 1/2(-3/4s + 1109)
Make 1/2(-3/4s + 1109) into a single fraction
a = -3/8s + 1109/2
Substitute -3/8s + 1109/2 for a in the other equation (a + s = 937).
-3/8s + 1109/2 + s = 937
Add -3/8s to s.
5/8s + 1109/2 = 937
Subtract 1109/2 from both sides.
5/8s = 765/2
Multiply both sides by 8/5, the reciprocal of 5/8.
s = 612
Now head back to the original equation, and substitute s for 612.
a = -3/8 * 612 + 1109/2
Multiply -3/8 by 612.
a = (-459 + 1109)/2
Add 1109 to -459 and divide by 2.
a = 650/2
a = 325
The system is solved. There are 612 students and 325 adults.
What are the answers to these questions
Answer:
1. v = 12
2. x =7
Step-by-step explanation:
Step-by-step explanation:
1) Multiply both sides by 5 to take away the fraction . You'll be left with v + 8 =20
Group the constants: v = 20 -8
v = 12

Which of the following shows the solution and graph to the inequality
2x + 1 ≤ 15?
Answer:
C or D
Step-by-step explanation:
I'm taking this same thing, not sure if it's c or d. The thing that I'm puzzled about is what the difference between the white dot and the black dot is.
Option D shows the solid dot along with [tex]x\leq 7[/tex] so our answer is
Option D.
The given inequality is 2x + 1 [tex]\leq[/tex] 15.
We have to see which of the given option shows the solution and graph to this inequality.
What are a solid dot and an open dot?A solid dot indicated on a number line graph shows that the given number is also a possible solution, whereas an open dot indicates that the given number cannot be a solution.
We see that in the given inequality, 2x + 1 must be less than or equal to 15.
And the maximum value we can take is 7 because,
2(7) + 1
14 + 1
15
So we can take 7 and any values less than 7 i.e [tex]x\leq 7[/tex] to satisfy the inequality 2x + 1 [tex]\leq[/tex] 15.
We see that Option D gives us [tex]x\leq 7[/tex] along with the solid dot.
Hence Option D is our answer.

A box contains 5 chocolate chip cookies, 4 sugar and 6 oatmeal raisin. What is the probability of picking a chocolate chip cookie?
plssss helpppp
Answer:
5/10
Step-by-step explanation:
if you add all the non- chocolate chip cookies than you have 10 other cookies.
since there are 5 chocolate chip cookies than the probability would be
5/10 or 1/2
The probability of picking a chocolate chip cookie is 1/3.
Given that, a box contains 5 chocolate chip cookies, 4 sugar and 6 oatmeal raisin.
What is the probability?Probability can be defined as the ratio of the number of favorable outcomes to the total number of outcomes of an event.
We know that, probability of an event = Number of favorable outcomes/Total number of outcomes
Here,
Total number of outcomes =15
Number of favorable outcomes = 5
Probability of an event = 5/15
= 1/3
Therefore, the probability of picking a chocolate chip cookie is 1/3.
