Rhonda' job i to drive a car for a company. Each month he i paid the ame alary. She i alo paid extra money for the number of mile he drive the car each month. • In July Rhonda drove 640 mile and wa paid a total of $3,502. 0. • In Augut Rhonda drove 820 mile and wa paid a total of $3,601. 0. Which function can be ued to find y, the total amount he i paid in a month if he drive × mile?
Answers
If Rhonda drives x miles in a month, she will be paid a total of $2,352 + ($0.55 * x).
We can use the information given to set up a system of equations to find the function that relates the number of miles driven (x) to the total amount paid (y).
Let's call the fixed salary that Rhonda receives each month "s" and the extra money she receives per mile driven "m".
Based on the information given, we know that in July, Rhonda drove 640 miles and was paid a total of $3,502. So, we can set up the following equation:
y = s + (m * 640) = $3,502
And in August, Rhonda drove 820 miles and was paid a total of $3,601. So, we can set up the following equation:
y = s + (m * 820) = $3,601
We can use these equations to solve for "s" and "m".
Subtracting the first equation from the second equation:
$3,601 - $3,502 = s + (m * 820) - s - (m * 640)
$99 = (m * 820) - (m * 640)
$99 = m * 180
m = $0.55
Now we can substitute this value of m back into one of the equations to solve for s
$3,502 = s + (0.55 * 640)
s = $2,352
So the function that relates the number of miles driven (x) to the total amount paid (y) is:
y = $2,352 + ($0.55 * x)
Thus, This means that if Rhonda drives x miles in a month, she will be paid a total of $2,352 + ($0.55 * x).

What do you call the triangle that have the same shape but not the same size?
Answers
The triangle that have the same shape but not the same size are similar triangles
What are Similar triangles ?Triangles with the same shape but different sizes are said to be similar triangles. Squares with any side length and all equilateral triangles are examples of related objects. In other words, if two triangles are similar, their corresponding sides are proportionately equal and their corresponding angles are congruent.
If the respective sides of two triangles have the same ratio and the corresponding angles are equal, then the triangles are comparable (or proportion). Triangles that are similar will have the same form but may not be the exact same size.
Two triangles are said to be similar if their corresponding angles are equal. Equiangular triangles are what they are called. Two equiangular triangles were the subject of a significant finding made by the well-known Greek mathematician Thales. He applied the Basic Proportionality Theorem, sometimes known as the Thales Theorem, as a conclusion.

What is percentage ?In mathematics, a percentage is a mathematical ratio that is stated as a portion of 100. Occasionally, the abbreviations "pct.," "percent," and "pt" are also used. However, the percentage symbol "%" is frequently used to represent it. There are no dimensions to the % quantity. Since percentages have a numerator of 100, they are actually fractions. A number must be followed by the cent symbol (%) to denote that it is a percentage. For illustration, you would receive a 75% mark if you answered 75 out of questions on a test correctly.
Here,
Given:
Saed discovered that he had barely traveled 18% of the

Answers
The rise is 231 feet 10 inches if the horizontal run of the roof is 15 feet 34 inches.
Let us assume that x represents the rise and y represents the run,
According to the given problem,
x= 15 feet 34 inches
Converting feet into inches,
we know, 1 feet = 12 inches
so, 15 feet 34 inches = 15*12+34 = 214 inches
Now finding the rise in terms of x and y,
13 = y/x
substituting the value of x and solving for y:
13 = y/214
y = 13*214
y = 2782 inches
Converting inches into feet,
2782 inches = 2782/12 = 231 feet 10 inches
Thus, The rise is 231 feet 10 inches if the horizontal run of the roof is 15 feet 34 inches.

Answers
Based on their percentages, the total number of students in Ridgewood Junior High School is 170.
What is the percentage?The percentage refers to the ratio or relative value of a variable or number compared to another.
Percentages are expressed as the product resulting from the multiplication of a quotient (numerator over denominator) by 100.
The percentage of students who brought their lunch = 20%
The number of students who brought their lunch = 34
Since all students either eat from the school cafeteria or bring their launch, the percentage of students who brought their lunch = 80% (1 - 20%).
34 = 20%
The percentage of students in the school = 100% (20% + 80%)
The number of students in the school = 34/20%

What is Pythagoras theorem?Pythagoras' Theorem states that the square of the hypotenuse side in a right-angled triangle is equal to the sum of the squares of the other two sides. The Perpendicular, Base, and Hypotenuse are the names of the three sides of this triangle.
Given:
dz/dt = 1,
dx/dt = 3(dy/dt)
So, dy/dt = 1/3 (dx/dt)
According to the Pythagoras theorem -
z² = x² + y²
Differentiating both sides we get
d/dt (z²) = d/dt (x² + y²)
2z dz/dt = 2x dx/dt + 2y dy/dt
z dz/dt = x dx/dt + y dy/dt
Substituting the value of dy/dt -
z dz/dt = x dx/dt + y/3 (dx/dt)
z dz/dt = dx/dt (x + y/3)
dx/dt = (z dz/dt)/(x + y/3).....(1)
So, when x = 12 and y = 5, the value of z -
z = √[(12)² + (5)²]
z = √(144+25)
z = √169
z = 13
Substituting the value of x, y, z and dz/dt in equation (1), we get
dx/dt = (13 × 1)/(12 + 5/3)
dx/dt = 13 / 41/3
dx/dt = (13 × 3)/41
dx/dt = 39/41

A function is a relationship between two variables, where the output of the function depends on the input. In a graph, the input is represented on the x-axis, and the output is represented on the y-axis.
The first graph pictured is a linear function, which is a function that can be expressed as a straight line. This linear graph has a positive slope, meaning that as the input increases, so does the output. This graph represents a linear function because the output can be determined by the input, which is expressed as an equation in the form of y = mx + b.
The second graph pictured is a quadratic function, which is a function that can be expressed as a parabola.
This graph also has a positive slope, meaning that as the input increases, so does the output. This graph represents a quadratic function because the output can be determined by the input, which is expressed as an equation in the form of y = ax2 + bx + c.
Both of these graphs represent functions because they show a relationship between the input and output of a given data set. The input values are shown on the x-axis and the output values are shown on the y-axis, and these values can be used to determine the equation for the function.

b) By what percentage does the air pressure decrease for each kilometre above sea level?
PLEASEE HELPP BEG!!!!
Answers
a) The air pressure at sea level is given by the formula when n = 0, so P = 1013 × 0.887 = 900.71 millibars.
b) To find the percentage decrease in air pressure for each kilometre above sea level, we can use the formula for percentage change:
(New Value - Original Value) / Original Value * 100
What is air pressure?Air pressure, also known as atmospheric pressure, is the force exerted on a surface by the weight of the air above it. Air pressure is typically measured in units such as millibars (mb) or inches of mercury (inHg). It plays an important role in weather patterns and can affect things like airplane flight and altitude sickness.
What is sea level?Sea level refers to the average level of the surface of the ocean. It is used as a reference point for measuring elevation, and for measuring air pressure at a specific location. At sea level, the air pressure is approximately 1013 millibars or 29.92 inches of mercury (inHg). Air pressure decreases as the altitude increases above sea level.
The new value is P = 1013 × 0.887^n and the original value is P = 1013 (at sea level)
So, the percentage decrease in air pressure for each kilometre above sea level is:
(1013 × 0.887^n - 1013) / 1013 * 100 = (-0.113n) * 100 = -11.3n %
So, the air pressure decreases by -11.3 % for each kilometre above sea level.

What is equivalent, equal and unequal sets?Equivalent sets are sets that contain the same number of elements. For example, if set A has three elements, and set B also has three elements, then set A and set B are equivalent sets. Equal sets are sets that contain the same elements. For example, if set A has the elements {1, 2, 3}, and set B also has the elements {1, 2, 3}, then set A and set B are equal sets.Unequal sets are sets that contain different elements. For example, if set A has the elements {1, 2, 3}, and set B has the elements {4, 5, 6}, then set A and set B are unequal sets. Unequal sets may still be equivalent sets. For example, if set A has the elements {1, 2, 3}, and set B has the elements {4, 5, 7}, then set A and set B are both still equivalent sets (as they both contain three elements), but they are unequal sets (as they contain different elements).To learn more about sets refer to:
