The value of the expression which shows the amount he paid for lunch is 7 dollars.
What is an expression?Expression in maths is defined as the collection of numbers variables and functions by using signs like addition, subtraction, multiplication, and divisions.
Given that Frankie orders two hamburgers and a soda for lunch. A hamburger is $3 and a soda is $1.00.
Now here is the expression-
1+(2x3)= 2 x 3 = $6
Cost of lunch = ($3 / hamburger) (2) + ($1 / soda) (1)
Cost of lunch = $6 + $1
Cost of Frankie's lunch = $7
Therefore, the value of the expression which shows the amount he paid for lunch is 7 dollars.

Katrina buys a 66-ft roll of fencing to make a rectangular play area for her dogs. Use 2(l+w) = 66 to write a function. for the length, given the width. Graph the function. What is a reasonable domain for the situation? Explain. The function f(w) = gives the length as a function of the width. (Simplify your answer.)
The function for the length when the width is given is l = 33 - w. The domain of the function is 0 < w < 33 and the graph of the function has been plotted
The total length of the roll = 66 feet
The perimeter of the rectangular paly area = 66
The perimeter of the rectangle = 2(l + w)
Then the equation will be
2(l + w) = 66
l + w = 66/2
l + w = 33
The function for length when the width is given
l = 33 - w
Therefore the domain of the function is 0 < w < 33
When w = 1
l = 33 - 1
l = 32
The first point is (1, 32)
When w = 32
l = 33 - 32
l = 1
The second point is (32, 1)
Draw the graph of the function
Hence, the function for the length when the width is given is l = 33 - w. The domain of the function is 0 < w < 33 and the graph of the function has been plotted

It makes x-values infinite but y-values restricted between the two lines.

2. Domain: (-∞, ∞)

Step-by-step explanation:
Definitions
Domain: The set of all possible input values (x-values).Range: The set of all possible output values (y-values).Open circle: The value is not included in the interval.Closed circle: The value is included in the interval.Arrow: The function continues indefinitely in that direction.Note: Assume that each square on the given graphs is 1 unit.
Question 1The domain of the function is restricted since the curve has two distince endpoints. As each endpoint is marked by a closed circle, the x-value of the endpoints is included in the domain.
Domain: [-2, 6]The function has a maximum point at (-1, 7) and a minimum point at (6, -3).
Therefore, the range of the function is restricted.
Range: [-3, 7]Question 2As there are arrows at both endpoints of the function, and the function is continuous between the arrowheads, the domain is unrestricted.
Domain: (-∞, ∞)The maximum y-value is y = 5. When x < 1, the line continues indefinitely at y = 5.
The minimum value is y = 1. When x > 1, the line continues indefinitely at y = 1.
Therefore, the range of the function is restricted.

An explicit formula for the arithmetic sequence is aₙ = 10 - 20(n - 1).
How to write an explicit formula for the arithmetic sequence?Mathematically, the nth term of an arithmetic sequence can be calculated by using this mathematical expression:
aₙ = a₁ + (n - 1)d
Where:
d represents the common difference.a₁ represents the first term of an arithmetic sequence.n represents the total number of terms.From the information provided, we have the following parameters:
First term, a₁ = 10
Second term, a₂ = -10
Next, we would determine the common difference as follows:
Common difference, d = a₂ - a₁
Common difference, d = -10 - 10
Common difference, d = -20
Substituting the parameters into the mathematical expression, we have;
aₙ = 10 + (n - 1)(-20)
aₙ = 10 - 20(n - 1).

The measure of angle Y, m ∠Y, is 52.58°. The correct option is the last option 52.58°
Calculating the measure of an angleFrom the question, we are to determine the measure of angle Y.
From the given information,
Angles X and Y are supplementary angles.
NOTE: Supplementary angles are angles that sum up to 180°
Thus,
m ∠X + m ∠Y = 180°
Also,
From the given information,
Angle X measures 127.42°
That is,
m ∠X = 127.42°
Therefore,
127.42° + m ∠Y = 180°
m ∠Y = 180° - 127.42°

party rental company has chairs and tables for rent. The total cost to rent 2 chairs and 3 tables is $25. The total cost to rent 6 chairs and 5 tables is $49. What is the cost to rent each chair and each table?
The cost to rent each chair and each table is $2.75 and $6.50 respectively.
How to calculate the cost?The total cost to rent 2 chairs and 3 tables is $25. This will be:
2c + 3t = 25
The total cost to rent 6 chairs and 5 tables is $49. This will be:
6c + 5t = 49
2c + 3t = 25
6c + 5t = 49
6 × (2c + 3t = 25)
2 × (6c + 5t = 49)
12c + 18t = 150
12c + 10t = 98
Subtract
8t = 52
Divide
t = 52/8
t = 6.5
Cost to rent table = $6.50
Since 2c + 3t = 25
2c + 3(6.5) = 25
2c + 19.5 = 25
Collect like terms
2c = 25 - 19.5
2c = 5.5
c = 5.5/2
c = 2.75
Cost to rent chair = $2.75.

The true solution for 2 ln e^ ln (5x) = 2 ln (15) is x = 3.
Given,
2 ln e^ ln (5x) = 2 ln (15)
Apply log rule;
logₐ (aᵇ) = b
ln (e^ln (5x)) = ln (5x)
2 ln (5x) = 2 ln (15)
Divide both sides by 2;
2 ln (5x) / 2 = 2 ln (15)/ 2
ln (5x) = ln (15)
For ln (5x) = ln (15), solve for 5x = 15;
That is,
5x = 15
Then,
x = 15/5
So,
x = 3
Check this by substituting it to 2 ln (5x) = 2 ln (15);
x = 3
2 ln (5 × 3) = 2 ln (15)

X is a positive rational number greater than 1. If the two integers that make up the ratio are both positive, then the numerator must be greater than the denominator for the value of the ratio to be greater than 1.

So, p - q must be a positive integer greater than 1 because it is a positive integer subtracted by a smaller positive integer.
Bob invested his savings in two investment funds. The amount he invested in Fund A was 3 times as much as the amount he invested in Fund B. Fund A returned a 5% profit and Fund B returned a 7% profit. How much did he invest in Fund B, if the total profit from the two funds together was $2200?
The amount that he invested in Fund B if the total profit from the two funds together was $2200 is $8,800.
How to find the amount invested?Let x represent the amount invested in Fund B
Let 3x represent the amount invested in Fund A
Hence,
.07x + .05(3x) = 2200
.07x + .15x = 2200

The coordinates of N are (5,-6) so that segment MN is 3/7 of MP.
Given the coordinates of M is (-4,6) and the coordinates of P is (17,-22).
now we have to find the coordinates of N such that the MN : NP is 3:4 .
We will use the section formula:
The section formula states that:
[tex]{\displaystyle N=\left({\frac {mx_{2}+nx_{1}}{m+n}},{\frac {my_{2}+ny_{1}}{m+n}}\right)}[/tex]
Where the coordinates of the points are given and the ratio in which the points are divided is given.
Now we will substitute the values:
[tex]{\displaystyle N=\left({\frac {17\times 3+4\times -4}{3+4}},{\frac {3\times-22+4\times 6}{3+4}}\right)}[/tex]
Solving we get:
N=(5,-6)
The Section formula is used to determine the coordinates of things like the point that separates a line segment (internally or externally) into a particular ratio.
Both physics and mathematics regularly employ this formula. In mathematics, it is used to find the centroid and incenters of a triangle, but in physics, it is used to find the center of mass, equilibrium points, etc. The section formula is often used to find the midpoint of a line segment.

The properties of operations to multiply the expression are commutative property, associative property, and distributive property.
Let us understand the properties of operations to multiplication:
The foundation of arithmetic is the Properties of Operations; we use them when performing computations and recalling basic facts.
There are basically three properties of operations to multiplication which are:
Commutative Property: The commutative property of multiplication states that the order in which values are multiplied does not matter and will result in the same answer. That is to say: a * b = b * aAssociative Property: The associative property of multiplication states that when three or more numbers are multiplied, the order in which the multiplication occurs has no effect on the answer. That is to say: (a * b) * c = a * (b * c)Distributive Property: Students are asked to create two groups of six (2 x 6) using connecting cubes and to locate two hidden facts inside the 2 x 6 such as 2 x 3 and 2 x 3. That is: 2 x 6 = 2 x 3 + 2 x 3.Thus, the properties of operations to multiply the expression are commutative property, associative property, and distributive property.
