The cost that will maximize the demand, considering the quadratic function, is given as follows:
$3.
How to maximize the demand?The quadratic function representing the demand is given as follows:
y = -10x² + 60x + 180.
The vertex of a quadratic function is the point on the graph where the function reaches its maximum or minimum value. For a quadratic function in standard form y = ax² + bx + c, the x-coordinate of the vertex is given by:
x = -b / (2a)
The coefficients of the quadratic function in this problem are given as follows:
a = -10, b = 60.
The x-coordinate is the price that maximizes the demand, hence it is obtained as follows:
x = -60/(2 x (-20))
x = 3.

Answers
#1:
Serena does not have enough albums to hold all the photographs.
Work:
40*36 = 1440
#2:
A group of 1,058 people is called in for jury duty.
Work:
A jury is made up of 12 jurors and 2 alternates.
1 jury = 12 jurors + 2 alternates = 14 members
So, the number of complete juries that can be formed is
= 1058/14 = 75.57
#3:
Gary's backpack will weigh 7.8 pounds with the math and science textbooks in it.
Work:
Total weight = backpack weight + math textbook weight + science textbook weight
Total weight = 1.2 + 3.75 + 2.85
Total weight = 7.8 pounds
#4:
Steven made 4.75 liters of punch.
Work:
Liters of Punch = orange juice + pineapple juice + sparkling water
Liters of Punch = 2.8 + 0.75 + 1.2
Liters of Punch = 4.75
Martin used a coordinate plane to design the garden shown. Each unit on the grid represents 10 yards.
How many square yards will the garden be after it is built? What is the total AREA of the garden?
Answers
Lets divide this into the big rectangle being separated from the smaller rectangle at the bottom.
To find the height of the big rectangle, subtract one y-coord of 30 from the other y-coord 80.
80-30=50
To find the length of the big rectangle, subtract one x-coord of 10 from the other x-coord of 100.
100-10= 90
Multiply these to get the area of the big rectangle:
90 x 50 = 4500 units squared
Next, find the smaller recatngle’s area by repeating the previous steps:
Height: 30-10 = 20
Length: 70-40 = 30
Now find the area:
20 x 30 = 600 units squared
Finally, add both of these areas up to find the total area for the original shape:
4500 + 600 = 5100 units squared

Daksha would like to save at least $500 in 12 months. What is the minimum amount she must save each month in order to save at least $500?
Answers
Answer:
$41.67
Step-by-step explanation:
To save at least $500 in 12 months, Daksha must save an average of at least $500/12 = $41.67 per month.
To find the minimum amount she must save each month, we can assume she saves a constant amount each month, and solve for that amount.
Let x be the amount she saves each month. Then over 12 months, she will have saved 12x dollars. To meet her goal of saving at least $500, we need:
12x ≥ 500
Solving for x, we get:
x ≥ 500/12
x ≥ 41.67
Therefore, Daksha must save at least $41.67 each month to save at least $500 in 12 months.

This Stem-and-Leaf Graph represents the students’ test scores in History. What is the median for the data in this Stem-and-Leaf plot?
A. 52
B. 59
C. 65
D. 73
Answers
Answer:
C. 65
Step-by-step explanation:
The 5 stem has scores of 52, 55, and 57.
The 6 stem has scores of 64, and 66.
The 7 stem has scores of 73, 75, and 79.
Together, the data is: 52, 55, 57, 64, 66, 73, 75, and 79.
The median is the middle number. We can cross out the two outside numbers and go in from there.
52 and 79 are crossed out. 55 and 75 are crossed out. 57 and 73 are crossed out.
When there are two numbers in the middle instead of one (ideally, the one left after this process is the answer), you go between those. Between 64 and 66 is 65.
A wallet contains 23 bills. All the bills are $1 bills and $5 bills. There are 7 more $1 bills than $5 bills. How much money does the wallet contain?
Answers
Answer:
Step-by-step explanation:
Let's say x is the number of $1 bills and y is the number of $5 bills. We know that:
x + y = 23
x = y + 7
We can use rearrange the second equation and add them together to find x. Then, we can plug x into any one of our equations to find y and calculate how much money is in the wallet.
x + y = 23
x - y = 7
2x = 30
x = 15 $1 bills
15 = y + 7
y = 8 $5 bills
15 * $1 + 8 * $5 = $15 + $40 = $55

someone, please help me. I need this done by today. Also, if you do do it, can you write part a and then part B
Answers
Answer:
Step-by-step explanation:
Part A: step 1 is correct, step 2 is wrong. Right side of the equation should be 12 - 21 = -9
Part B:
-14x + 21 = 30x + 12
-14x - 30x = 12 - 21
-44x = -9
x = -9/-44 = 9/44
You are buying fruit to make fruit baskets. Apples come in bags of 20. Oranges come in bags of 16 and bananas come in bags of 32.
2. You decide that not only must the fruit baskets be identical, but each one must have the same number of apples, oranges, and bananas.
a. What is the least number of bags of each fruit you need to have the same number of apples, oranges, and bananas? I
b. How many of each type of fruit do you have?
c. There must be at least 5 but no more than 10 of each type of fruit in each basket.
How many different ways can you arrange the fruit baskets when using all of the fruit? Explain your reasoning.
Answers
Answer:
You will need to find the least common multiple of 20,16, and 32. The least common multiple of all those will be 160. you will need 8 bags of apples, 10 bags of oranges, and 5 bags of bananas. so for a I believe it would be 8 bags of apples 10 bags of oranges and 5 bags for bananas. as for b it should be 160. and for c you could arrange either 5 of each fruit for 32 baskets, 10 of each for 16 baskets, or 8 of each for 20 baskets

Loss of water=12%
Using formula,used/total*100
=12/55*100
=12/11*20
=12*20/11

=21.81
Thus, 21 gallon of water was lost

Question for points :3
The base of a parallelogram is 14 inches, The area of the parallelogram is 98 square inches. Find h the height of the parallelogram.
Answers
Answer:
7 inches
Step-by-step explanation:
The formula for the area of a parallelogram is given by A = bh, where A is the area, b is the base, and h is the height.
The parallelogram base is 14 inches, and the area is 98 square inches. Substituting these values into the formula, we get:
98 = 14h
Solving for h, we can divide both sides by 14:
h = 7
Therefore, the height of the parallelogram is 7 inches.
Write and evaluate an expression that tells you to subtract 6 from 9 then subtract the difference from 12 and then multiply by 3 use at least two types of grouping symbols
Answers
Step-by-step explanation:
One possible expression using two types of grouping symbols is:
3 × [(12 - (9 - 6))]
This expression first subtracts 6 from 9 to get a difference of 3, then subtracts that difference from 12 to get a result of 9. Finally, it multiplies 9 by 3 to get a final answer of 27. The grouping symbols used are parentheses to group the subtraction of 6 from 9, and then another set of parentheses to group the subtraction of that difference from 12. The outermost grouping symbols are the multiplication symbol and the pair of brackets used for clarity.
