Answer:
The classical inequalities are several generalized inequalities that have wide use in algebra. They are often used for determining the minimum and maximum values of functions. Although maximums and minimums can be found using methods from calculus, the application of a classical inequality is often a simpler approach. In conclusion, inequality is important for determining the calculus and the numbers to solve a problem.

QUESTION 1
The value of the x for the given square such that its perimeter is 28 meters will be 3.7 meters.
What is a square?
A square is a geometrical figure in which we have four sides each side must be equal and the angle between two adjacent sides must be 90 degrees.
Area of square = Side²
The perimeter of the square = 4 × side
As per the given square perimeter.
4(x + 3.3) = 28
x + 3.3 = 7
x = 3.7 meters.
Hence"The value of the x for the given square such that its perimeter is 28 meters will be 3.7 meters".

A scale model of the Sergeant Floyd Monument is 10
inches tall. The actual monument is 100 feet tall. What is
the scale of the model? What is the scale factor?
Answer:
1/120 or 120
Step-by-step explanation:
Actual monument is 1200 inches tall so that means if we want to find the scale of the model then we do 10/1200 so that = 1/120 or if we are finding the scale factor from the model to the actual then it is 120.

Meg laid 15 tiles in 50 minutes.
Jessica worked for 85 minutes at a faster rate per tile than Meg.
Choose all the rates that could be Jessica’s rate.
20 tiles in 85 minutes
24 tiles in 85 minutes
28 tiles in 85 minutes
1 tile in 3 minutes
1 tile in 4 minutes
Answer:
The correct options are C and D
Important information:
Meg laid 15 tiles in 50 minutes.
Jessica worked for 85 minutes at a faster rate per tile than Meg.
Step-by-step explanation:
The rate per tile of Meg is:
Rate = time/no. of tiles
Rate = 50/15
Rate = 3.333333...etc
Calculate the rates per tile for each option.
85/20 = 4.25
85/24 = 3.54167...
85/28 = 3.0357
3/1 = 3
4/1 = 4
From the above calculation is clear that the time spent per tile is less than Meg's rate in options C and D.
Therefore, the correct options are C and D.
Please Help guys!!!
-Graphing Linear equalities with slope and y-intercept-
Answer:
If Ali has $9 and spends $2 each week buying chips. This means that the equation is: y = 9 - 2x. This is because the equation is calling for the amount of money Ali has left, which means that you have to subtract 2 times the amount of weeks passed from 9.
Week 1 ---- y = $7
Week 2 ---- y = $5
Week 3 ---- y = $3
You can also notice that each week the amount of money Ali has left decreases by 2.
Factor this expression completely and then place the factors in the proper location on the grid.

Write the equation for the line of best fit in the slope-intercept form and use it to predict the number of matches that could be won after 13 months of practice Show your work and include the points used to calculate the slope. (5 points)
The slope-intercept is y=mx+b where m= the slope and b= the y-intercept. it looks like the y-intercept is about 3.5 or 3 1/2. One way to find M is that you take 2 points, ill do (1,5) and (5,12), and then subtract the x's with the x's and the y's with the y's and you would get (1-5, 5-12) which equals -4,-7. then you put the y's on top of a fraction and the x's on the bottom. so you would get -7/-4 when both numerator and denominator are both negative then they cancel out. making the total M= 7/4 which also equals 1 and 3/4, since you want to know after 13 months, the number of months =x so you can substitute and this is your equation: y= 7/4x+ 3.5 substituting the number of months: y= 7/4(13) + 3.5. 7/4 * 13 = 22.75 then you add the 3.5 which equals 26.25 so.
after 13 months of practice, the number of matches won would be about 26.
A spinner with five equal-sized colored sections is spun with the results shown in the table. Based on the experimental probability, predict the number of yellow results for 300 trials.
Red Orange Yellow Green Blue
16 15 20 14 15
A.75
B.60
C.40
D.20
Answer: 75
Step-by-step explanation:
Add the values given in the table
16+15+20+14+15 = 80
Yellow happens 20 times out of the 80 times total.
The experimental probability of yellow is 20/80 = 1/4 = 0.25 = 25%
If we do 300 trials, then we predict yellow to happen 0.25*300 = 75 times.
The charity gala costs a flat fee of $4, plus an additional $11 per attendee. Is the total cost directly proportional to the number of attendees?
No, the total cost is not directly proportional to the number of attendees because there is a flat fee of $4 that does not depend on the number of attendees. If the total cost were directly proportional to the number of attendees, then the cost per attendee would be constant regardless of the number of attendees, but in this case, the cost per attendee decreases as the number of attendees increases due to the fixed flat fee.

Answer: M = 2
Step-by-step explanation:
Combine like terms!
5m + 8m = 13m
3 + 7 +4^2 =
3 + 7 + 16 = 26
13m = 26
M = 2.
Check!
5(2) + 8(2)
= 10 + 16 = 26!
3 + 7 +4^2 =
3 + 7 + 16 = 26
26 = 26
Hope this helps :)
Two friends have gone on vacation together. On Monday, they each chose a different activity. One friend went in a helicopter and went 128 feet above the ocean. The other friend decided to go diving and he was 28 feet below sea level in the water. What is the distance between the 2 friends if they were directly above each other at the same time?
Answer: The answer would be 100.
Step-by-step explanation: The answer would be 100 because one friend is 128 feet above the ocean right, then the other friend is 28 feet below sea level in the water OK. So if one is 128 feet above sea level then that's a positive 128 feet. Now if the other friend is 28 feet below sea level in the water well then that's a negative 28 feet. So then what I would do is i would subtract 128 from 28 and get my answer of 100 feet apart from each other. Hope i helped and have an amazing day, and good luck on any upcoming test that you might have. I hope you Ace them all:) Good day buddy.
