The price that would yield maximum revenue is $260 and maximum revenue is $1,690,000
What is the revenue function?
The fact that total revenue of the company is the price per purse multiplied by the number of purses sold, means that the revenue modelled function is simply price multiplied by the quantity sold as shown below:
R(x)=P*x
R(x)=Px
R(3000)=$400*3,000
R(3000)=$1200,000
Note for every 500 more purses, the price reduces by $20

The length and breadth of a land are x m and y m respectively . If perimeter of the land is 420 m, then
a. Write the equation which represent perimeter of land
b. If length of the land is 120 m, then find the breadth
Answer:
90 m
Step-by-step explanation:
a. Perimeter = 2( length + breadth) 2(x + y)
Answer: Perimeter: 2(x + y) = 420
or 2x + 2y = 420
Using the values given
b.
2x + 2y = 420 (perimeter p= 420)
2(120) + 2y = 420 (length x = 120)
240 + 2y = 420
2y = 420 - 240 = 180 (subtract 240 on both sides)
y = 190/2 = 90 m

A percentage is a number or ratio expressed as a fraction of 100.
From the given information:
a hospital day staff consists of 25 registered nurses, 75 unlicensed assistants, five phlebologists, six receptionists and office staff, and 45 physicians. one summer day the staff was at only 68% strength.
Then
Total number of staff = 25+75+5+6+45
Total number of staff = 156
Then
the staff was at strength = 68%
And then
Number of people working on that day = 68% of 156
And
Number of people working on that day = 68/100 *156
Number of people working on that day = 0.68*156
Number of people working on that day = 106.08
Approximate 107 people.

Answer: See diagram below
Scale factor = 3
============================================================
Explanation:
The given L shape has a perimeter of 3+1+2+1+1+2 = 10 units. I added up the exterior sides of this shape.
We want the perimeter to be 30 units, so we scale it by a factor of 3. Since 30/10 = 3.
This means we'll triple each side
The vertical side on the left originally 3 units long is now 3*3 = 9 units. The bottom side that is 2 units long is now 2*3 = 6 units. And so on.
See the diagram below.
Notice in the red figure the sides add to 9+3+6+3+3+6 = 30 to help confirm our answer.

GIVEN THE FOLLOWING:
Mario's car rate consumption. R = 24.5mile/gallon
Distance covered each day, D = 32.3 miles
Cost of gas $2.89/gallon
REQUIRED: (a) To calculate how much he spends on gas each week.
We proceed as follow:
Mario uses 1 gallon of gas for every 24.5 miles.
For 32.3 miles, he will use [tex]\frac{32.3}{24.5} ~gallons~ of gas=\frac{325}{245} ~gallons[/tex]
Now, a gallon of gas costs $2.89
[tex]\frac{325}{245}~gallons~will~cost =?[/tex]
[tex]\frac{325}{245} ~*2.89=3.81[/tex]
$3.81 is how much he spends each workday.
There are 5 working days in a week.
Therefore, for a week, he spends:
[tex]3.81~*~5~=19.05[/tex]
therefore, for each work week, he spends $19.05 on gas.
(B) To calculate how many miles he can drive with $15.00 worth of gas
We proceed thus:
A gallon of gas costs $2.89.
$15.00 will amount to:
$15.00/$2.89 = 5.19 gallons
Recall that Mario uses 1 gallon of gas for every 24.5 miles.
Therefore, 5.19 gallons will be used for:
[tex]5.19~*24.5=127.155 ~miles[/tex]
≈ 127 miles
Therefore, with gas worth $15.00, Mario will cover a distance of 127 miles

What will be the location of the y value of R' after using the translation rule (x + 4, y - 7), if the pre-image R is located at ( -17, -3)
Using translation concepts, the y-coordinate of R' will be of -10.
What is a translation?A translation is represented by a change in the function graph, according to operations such as multiplication or sum/subtraction either in it’s definition or in it’s domain. Examples are shift left/right or bottom/up, vertical or horizontal stretching or compression, and reflections over the x-axis or the y-axis.
For this problem, the rule is given by:
(x,y) -> (x + 4, y - 7)
y -> y - 7 means that for the image, the 7 is subtracted from the y-coordinate of the pre-image. The y-coordinate of R is of -3, -3 -7 = -10, hence the y-coordinate of R' will be of -10.

The eight machines can be arranged in the three available spaces in 336 ways.
Here we have 8 screw machines with 3 spaces. To find the different way, permutation will help.
Different ways = 8 P 3
= 8! / (8! -3!)
= 8! / 5!

The percentage of vacationers who spent less than $1,200 per 12-day vacation is 7.78%.
What is normal distribution?The normal distribution, also recognized as that of the Gaussian distribution, would be a symmetric probability distribution about the mean, indicating that data near the mean occur more frequently than data far away from the mean. The normal distribution is represented graphically as a "bell curve."
Now, according to the question;
The formula for finding the z-score is;
z = (x - μ)/σ
where,
x is the score
μ is the mean
σ is the standard deviation.
Summer vacation costs $1,755 for the average local family.
The distribution is normal, with a standard deviation of $390.
We need to figure out what percentage of families took vacations less than $1200.
The mean is $1,755
∴ μ = $1,755
∵ The standard deviation is $390
∴ σ = 390
∵ The vacation cost is under $1200
∴ x = $1200
Substitute the values in the formula of z score.
z-score = (1200 - 1,755)/390 = -1.42
Use the negative normal distribution table of z
P(z < 1,200) = 0.07782
P(x < 1,200) = P(z < 1,200)
P(x < 1,200) = 0.07782
P(x < 1,200) = 7.78%

The width rectangle is three less than twice its length. If the area of the rectangle is 193 cm² what is the length of the diagonal?
Answer:
Step-by-step explanation:
Givens
Let the Length = L
Let the width = w
w = 2*L - 3
Area = L * w
Area = 193
Solution
Area = 193
193 = L*(2L - 3)
193 = 2L^2 - 3L Subtract 193 from both sides.
2L^2 - 3L - 193 = 0
You have to use the quadratic formula get the answer. Without going through all all that, I will tell you that the only value you can use for L is 10.6
L = 10.6
w = 2* 10.6 - 3 = 18.4
But you want the diagonal. Use the Pythagorean Theorem to get it.
Diagonal^2 = L^2 + w^2
Diangonal^2 = 10.6^2 + 18.4^2
Diagonal^2 = 450.92 Take the square root of both sides

The age of Mrs. Lee when her 2 children's combined age is [tex]\frac{5}{11}[/tex] of her age will be [tex]44[/tex] yrs. old
As per the question statement, Mrs. Lee, who is 40, has a son who is twice as old as her daughter. Mrs. Lee will be thrice her son's age when her daughter is 12-year old. We are asked that how old Mrs Lee be when her two children's combined ages are 5/11 of her own age.
This question is a classic example of forming and solving linear equations.
When Mrs. Lee was 40, her son was twice her daughter's age.
Let d = her daughter's age when Mrs. Lee was 40.
Then her son was 2d yrs. old when Mrs. Lee was 40.
When her daughter is 12, Mrs. Lee will be three times her son's age.
This means [tex](12 - d)[/tex] years have passed since Mrs. Lee was 40.
So, if her daughter was 12 at this time, that means her son was [tex]2d + (12 - d)[/tex]
And, Mrs. Lee's age at this time was [tex]40 + (12 - d)[/tex]
Mrs Lee was thrice her son's age at this time:
[tex]40 + (12 - d) = 3(2d + 12 - d))[/tex]
[tex]40+12-d=6d+36-3d\\4d=16\\d=4[/tex]
So, Mrs. Lee's age when her daughter was 12 is [tex]40 + 12 - 4 = 48[/tex] yrs. old
Her daughter was 8 yrs. old 4 years earlier.
Thus, Mrs Lee's age when her daughter was 20 was [tex]48 - 4= 44[/tex] years old.

We need to know about logic statements to solve this problem. The solution of the logic statements are 0 and 1 respectively.
Logical operators are used to form logical statements, logical operators compute result based on boolean values true and false or binary 1 and 0. The common logical operators are AND and OR. AND is represented by ^ symbol and OR is represented by v symbol, ' means negation of the value, which means that true becomes false and vice versa. For AND operator, it works like multiplication, 0 and 1 yield 0, 1 and 1 yields 1 and 0 and 0 yields 0. For OR operator it works like addition, 0 and 1 yields 1, 1 and 1 yields 1 and 0 and 0 yields 0. For the logical statements given in the question we need to first compute the logical statement inside the bracket and then compare the inner result with the outer value.
(1'^0)^1 =(0^0)^1=0^1=0
(1v0')^(0v1)=(1v1)^(0v1)=1^1=1
