A square has an area of 144 ft^2 what is the length of each side
Answer: 12 feet
This is because [tex]12^2 = 12*12 = 144[/tex]
Squaring a number means you multiply it with itself.
The square root goes in reverse to have [tex]\sqrt{144} = 12[/tex]
Answer:
Each side is 12 ft long.
Step-by-step explanation:
So, you have a square, which means all of the sides are going to be the same length. So, you need something times itself that equals 144. Or, you need the square root of 144 (Because when something is squared, it is multiplied by itself). And the square root of 144 is 12.
A square napkin has sides of length 8 inches. To the nearest inch, what is the length of the diagonal of the (1
napkin?
O8 inches
09 inches
O11 inches
O16 inches
The length of the diagonal of the napkin is 11 inches.
Here, we are given that a square napkin has a side of length 8 inches.
All the sides of a square are equal and the measure of angle formed by any two adjacent sides is also equal and 90°.
Thus, by using Pythagoras theorem, we can form the following equation-
[tex]side^{2} + side^{2} = diagonal^{2}[/tex]
Let the diagonal of the square be d. Then, we have-
[tex]8^{2} +8^{2} =d^{2}[/tex]
64 + 64 = [tex]d^{2}[/tex]
128 = [tex]d^{2}[/tex]
[tex]d^{2}[/tex] = 128
d = [tex]\sqrt{128}[/tex]
d = [tex]8\sqrt{2}[/tex]
the value of [tex]\sqrt{2}[/tex] is approximately 1.41. Thus,
d = 8 × 1.41
= 11.28
Thus, the length of the diagonal of the napkin to the nearest inch comes out to be 11.

A clothing designer is selecting models to walk the runway for her fashion show.
The designer prefers models that are no more than 3 inches away from being 5'10".
Since 5'10" is the same as 70 inches, write an inequality - in terms of inches - that
could be used to determine if a model's height is within the designer's preferred height
range.
Using proportions, the inequality that could be used to determine if a model's height is within the designer's preferred height range is of:
67 inches ≤ Height ≤ 73 inches.
What is a proportion?A proportion is a fraction of a total amount, and equations can be built to find the desired measures in the problem using operations such as multiplication and division, from the unit rates in the context of the problem.
One example of application of proportions is for conversion of units, as there are rates for each unit.
In the context of this problem, the rate used is:
1 feet = 12 inches.
Hence the measure of 5'10" = 5 feet and 10 inches is given by:
5 x 12 + 10 = 60 + 10 = 70 inches.
The heights that are within 3 inches of 70 inches are given by:
70 - 3 = 67 inches.70 + 3 = 73 inches.Hence the inequality that models the situation is:
67 inches ≤ Height ≤ 73 inches.

The value of a baseball player's rookie card began to increase once the player retired. When he retired in 1997 his card was worth $6.36. The value has increased by $1.93 each year since then. Express the relationship relating the value of the card y in dollars and the number of years x the player has been in retirement with an equation. Is the relationship between x and y proportional? What was the value of the card in 2007
?
Part a: The relationship between x and y can be represented as y = 6.36 + 1.93x
Part b: The relationship between x and y is proportional
Part c: The value of the card in 2007 will be $25.66
Worth of the card in 1997 = $6.36
Increase in value each year = $1.93
Let x be the number of years the player has been in retirement and y be the value of the cards in dollars
Formulating the equations we get the following:
Value of the card = Worth of the card in 1997 + Increase in value each year*Number of years the player has been in retirement
Part a:
y = 6.36 + 1.93x
Part b:
The relationship between x and y is proportional as the increase in the value each year leads to an increase in the worth of the card
Part c:
Value of the card in 2007:
The number of years the player has been retired will be 10 years in this case
Formulating the equation we get the following:
y = 6.36 + 1.93(10)
= 25.66

Composition of Functions and Inverses:Question 7Which expression represents f(f(x)) if f(x) = x2 – 1? A. 2x ^2-2 B. X^4-2x^2+1C. XD. X^4-2x^2
To solve the question, we will follow the steps below:
[tex]f(x)=x^2-1[/tex]To find f(f(x)), we will simply replace x by x² - 1 in the function x² - 1
That is:
f((fx)) = (x²-1)² - 1
Then we open the parenthesis
f(f(x)) = (x² - 1)(x² -1) - 1
=x²(x²-1)-1(x²-1) - 1
= x⁴ - x² - x² + 1 - 1
= x⁴ - 2x²
So the correct option is option D. which is x⁴ - 2x²
The drama club is selling tickets to its play. An adult ticket costs $15 and a student ticket costs $11. The auditorium will seat 300 ticket-holders. The drama club wants to collect at least $3630 from ticket sales.
a. Write and graph a system of four inequalities that describe how many of each type of ticket the club must sell to meet its goal.
b. List three different combinations of tickets sold that satisfy the inequalities.
The system of inequalities is x + y ≤ 300, 11x + 15y ≥ 3630, x ≥ 0 and y ≥ 0 while the three points are (70, 200), (150, 140) and (140, 150)
How to graph the systemFrom the question, we have the following parameters that can be used to determine system of inequalities
An adult ticket = $15Student ticket = $11. Auditorium capacity = 300 ticket-holdersAmount from sales = at least $3630 from ticket sales.Represent the adult with y and the students with x
So, we have the following representations
x + y ≤ 300 ---- the ticket holders cannot exceed the capacity
11x + 15y ≥ 3630 --- the total sales cannot be less than $3630
x ≥ 0 -- the number of students cannot be negative
y ≥ 0 -- the number of students cannot be negative
Write out the inequalities
x + y ≤ 300
11x + 15y ≥ 3630
x ≥ 0
y ≥ 0
Next, we represent the inequalities on a graph
See attachment for the graph of the inequalities

f(10) multiple of 12 is given as:
The first-degree equations that make up a polynomial's linear factors serve as the foundation stone for higher-order and more complicated polynomials. The formula for a linear factor is ax + b, and it cannot be factored further. When paired with other linear factors, each linear factor represents a separate line, resulting in several sorts of functions with progressively more intricate graphical representations.

The gross monthly income range to be for you to be able to rent this apartment is $1671 - $2340.
How to calculate the value?Let the monthly income be x.
Therefore, 25% of x = 585
0.25x = 585
Divide
x = 585/0.25
x = $2340
The maximum income is $2340.
The minimum income will be:
35% of x = 585
0.35x = 585
Divide.
x = 585 / 0.35
x = $1671
In this case, the minimum value is $1671 and the maximum value is $2340. This illustrates the concept for finding the range.

Keandre wants to buy a new pair of shoes that costs $220. In order to earn money for this, Keandre babysits his neighbor for $10 an hour. He also has saved up his monthly allowance which totals $50. What is the minimum number of hours he should babysit in order to be able to afford the shoes?
Answer:
Step-by-step explanation:
$220=$10x+$50
x= hours
subtract $50 from both sides making sure to cancel the right side
$220-$50=$10x
$170=$10x
Divide both sides by $10 to leaving x by itself on the right side
$170/$10=x
17hrs=x
The minimum number of hours is 17 hours to babysit in order to be able to afford the shoes.
What is an expression?
Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.
Given that;
Cost of new pair of shoes = $220
In order to earn money for this, Keandre babysits his neighbor for $10 an hour.
And, He also has saved up his monthly allowance which totals $50.
Now,
Let number of minimum hours = x hour
So, We can formulate;
⇒ $10x + $50 = $220
Solve for x as;
⇒ $10x + $50 = $220
Subtract 50 both side, we get;
⇒ $10x + $50 - $50 = $220 - $50
⇒ $10x = $170
Divide by 10 both side, we get;
⇒x = 17
Thus, The minimum number of hours is 17 hours to babysit in order to be able to afford the shoes.
