Mario make total $132.1 from the tip of his two customers.
The amount of tip obtained = total bill × percentage of the bill
Put the respective values in equation depending on the customer A or B
Tip from customer A
Tip = 430.50 × 20%
Now find percentage by multiplication and division on Right Hand Side of the equation
Tip = $86.1
Tip from customer B
Tip = 184 × 25%
Again perform multiplication and division on Right Hand Side of the equation
Tip = $46
Total tip earned = 86.1 + 46
Simply add the two numbers on Right Hand Side of the equation to find the total tip earned
Total tip earned = $132.1

What are the 6 parent functions?
These are the 6 parent functions: Identity, Absolute Value, Square Root, Quadratic, Cubic, Reciprocal.
A parent function is the simplest form that a function can be. Its basic shape is not in any way altered. In mathematics, you see certain graphs over and over again. For that reason, these original, common functions are called parent graphs, and they include graphs of quadratic functions, square roots, absolute values, cubics, and cube roots.
For instance, when you see a u-shaped graph that is inverted and vertically stretched, you should still recognize that it is a parabola which has undergone different transformations.
We can take a few examples to understand this concept further.
For a quadratic equation, the parent graph is [tex]f(x) = x^{2}[/tex], which is a parabola.For a cubic equation, the parent graph is [tex]f(x) = x^{3}[/tex].Now, there are 6 parent functions:

what is domain?The range of values a function may accept is referred to as its domain. These numbers represent the x-values of a function like f. (x). The range of values that a function may operate on is referred to as its domain. The value that the function returns following the insertion of the x value is this set. A function containing the independent variable x and the dependent variable y is said to be y = f(x). A value of x is said to be in the domain of a function f if it can be used to successfully create a single value y utilizing the value of x for that purpose.

The two angles shown are supplementary. Down below
Answer:
x = 48
Step-by-step explanation:
If the two angles are supplementary then their sum must be 180 degrees
x + 34 + 2x + 2 = 180
3x + 36 = 180 subtract 36 from both sides
3x = 144 divide both sides by 3

How do you solve this?.....Katherine has a loyalty card good for a 3% discount at her local grocery store. What number should she multiply the prices on the tags by to find the price she would have to pay, before tax, in one step?
Answer:
Step-by-step explanation:
To find the number Katherine should multiply the prices on the tags by to find the price she would have to pay before tax, we need to calculate the inverse of the discount percentage, which is 1 - (discount percentage / 100).
Given that the discount is 3% and we want to find the price after the discount, that means:
1 - (3/100) = 1 - 0.03 = 0.97
So, the number Katherine should multiply the prices on the tags by to find the price she would have to pay, before tax, in one step, is 0.97. Multiplying the price of an item by 0.97 is equivalent to subtracting 3% from the original price, which is the same as finding the final price after the discount.
For example, if an item is priced at $10, Katherine can multiply this by 0.97 to find that the final price she would have to pay before tax is $9.7
10*0.97 = 9.7

What is Scale Factor?To adjust the size of a figure without altering its shape, a scale factor is a number or conversion factor that is utilised. It is employed to change the size of an object. If the original figure's dimensions and the dilated (increased or lowered) figure's dimensions are known, the scale factor can be determined.
Given:
As, The scale “1 inch to 6 feet” is equivalent to the scale “1 to 72,” because there are 72 inches in 6 feet.
The scale “1 to 100” would make a scale drawing that is smaller than the scale “1 to 72,” because each inch on the new drawing would represent more actual length.
The scale “1 to 50” would make a scale drawing that is larger than the scale “1 to 72,” because Kiran would need more inches on the drawing to represent the same actual length.

Correct option is B, The three zeros are 2, 3, -3.
The zeros of a function are the values of its variables that meet the equation and result in the function's value being equal to 0. The zeros of a function can be represented graphically as the x-coordinates (or x-intercepts) where the graph intersects the x-axis.
If a number's unit digit or end indicates a zero, it is a multiple of 10 and so divisible by 10. As a result, the amount of zeros at the end of every number determines how many times it may be raised to the power of 10.

Step-by-step explanation:
Which two ratios form a proportion?
Responses
A 12/15 and 5/4
B 15/12 and 5/4
C 6/5 and 4/5
D 5/6 and 4/5
Answer:
Step-by-step explanation: We will determine if ratios are proportional using cross multiplication.
first, we will check option (a)
12/15 =5/4
12*4 = 15*5
48 is not equal to 75. So, these are not proportional.
now, we will check option (b)
15/12 = 5/4
15*4 = 12*5
60 = 60.
as the left-hand side is equal to the right-hand side.
So, option (b) is correct.
Answer:
[tex]\textsf{B)} \quad \dfrac{15}{12}\; \textsf{and}\;\dfrac{5}{4}[/tex]
Step-by-step explanation:
If two fractions are equal, they form a proportion.
Therefore, to determine if two ratios form a proportion, rewrite the fractions so that their denominators are the same, then compare.
[tex]\textsf{A)}\quad \dfrac{12}{15}\; \textsf{and}\;\dfrac{5}{4} \implies \dfrac{12 \times 4}{15\times 4}\; \textsf{and}\;\dfrac{5\times 15}{4\times 15}\implies \dfrac{48}{60}\; \textsf{and}\;\dfrac{75}{60}[/tex]
As the two fractions are not equal, they do not form a proportion.
[tex]\textsf{B)} \quad \dfrac{15}{12}\; \textsf{and}\;\dfrac{5}{4}\implies \dfrac{15}{12}\; \textsf{and}\;\dfrac{5 \times 3}{4 \times 3}\implies \dfrac{15}{12}\; \textsf{and}\;\dfrac{15}{12}[/tex]
As the two fractions are equal, they form a proportion.
[tex]\textsf{C)} \quad \dfrac{6}{5}\; \textsf{and}\;\dfrac{4}{5}[/tex]
The denominators of these two fractions are already the same.
Therefore, as the two fractions are not equal, they do not form a proportion.
[tex]\textsf{D)} \quad \dfrac{5}{6} \; \textsf{and}\;\dfrac{4}{5}\implies \dfrac{5\times 5}{6\times 5} \; \textsf{and}\; \dfrac{4\times 6}{5\times 6}\implies \dfrac{25}{30}\; \textsf{and}\;\dfrac{24}{30}[/tex]
As the two fractions are not equal, they do not form a proportion.

What is the right triangle?
A right-angle triangle is a triangle that has one of its angles 90 degrees. The sum of angles in a right triangle is 180 degrees.
To find the measures of angles 1 and 2, we can use the fact that the sum of the angles in a triangle is 180 degrees.
We know that angles 1, 2, and 3 form a triangle, so we can write:
m∠1 + m∠2 + m∠3 = 180
Substituting the given values, we get:
m∠1 + m∠2 + 80 = 180
Simplifying, we get:
m∠1 + m∠2 = 100
We also know that angles 2, 3, and 4 form a triangle, so we can write:
m∠2 + m∠3 + m∠4 = 180
Substituting the given values, we get:
m∠2 + 80 + 85 = 180
Simplifying, we get:
m∠2 = 15
Substituting this value in the first equation, we get:
m∠1 + 15 = 100
Simplifying, we get:
m∠1 = 85
Therefore, the measure of m∠1 = 85 degrees and m∠2 = 15 degrees.
The correct answer is option D: ∠1 = 85°, m∠2 = 15°.

Since we are not given the total number of batches. Let us assume the total batches is 81
If each brownie is 1/9 of a batch, number of brownie made will be equivalent to:
Amount of brownie made = 1/9 × 81
Amount of brownie made = 81/9 = 9 brownies
Hence he made 9 brownies
