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).

The value of is dx/dt = 0.95, when x = 12 and y =5.

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

Hence, the value of dx/dt = 0.95.

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.

Tony earned $220

Step-by-step explanation:

Tony = n

Jenifer = x

Chris = y

x = 2n - 40

y = n + 60

Write an equation for the total the three waiters earned. Solve for Tony's earnings.

n + x + y = $900

n+2n−40+n+60=900

Step 1: Simplify both sides of the equation.

n+2n−40+n+60=900

n+2n+−40+n+60=900

(n+2n+n)+(−40+60)=900(Combine Like Terms)

4n+20=900

4n+20=900

Step 2: Subtract 20 from both sides.

Based on their percentages, the total number of students in Ridgewood Junior High School is 170.

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%

= 170

Thus, using percentage ratios, we can conclude that the total number of students in the school is 170.

Answer:

altitude ≈ 23 cm

Step-by-step explanation:

since the triangle is isosceles then the altitude AD is the perpendicular bisector of BC , so

BD = [tex]\frac{1}{2}[/tex] BC = 7 cm

using Pythagoras' identity in right triangle ABD

AD² + BD² = AB²

AD² + 7² = 24²

AD² + 49 = 576 ( subtract 49 from both sides )

AD² = 527 ( take square root of both sides )

AD = [tex]\sqrt{527}[/tex] ≈ 23 cm ( to the nearest whole number )

then the altitude is approximately 23 cm

Answer:

vertex of point A′ is A′(4.5, 3)

Step-by-step explanation:

To determine the vertex of point A′ after dilation, we need to know the coordinates of point A and the scale factor of the dilation.

In this problem, point A has the coordinates (3, 2) and the scale factor of the dilation is 1.5.

To find the coordinates of the dilated point, we multiply each of the original coordinates by the scale factor:

A'(x,y) = (1.5* x, 1.5*y)

So the coordinates of the point A' are:

A'(1.53, 1.52) = (4.5, 3)

Therefore, vertex of point A′ is A′(4.5, 3)

The vertex of point A after the dilation is A′(4.5, 3)

Dilation is a transformation that changes the size of a figure or an object without changing its shape.

The figure or object and its image after dilation are similar.

The size of the figure or object may increase or decrease based on a number called the scale factor.

Dilation is defined by a point called the center of dilation and the scale factor.

Given that, a triangle ABC, has been dilated by a scale factor of 1.5.

We need to determine the vertex of A',

The rule of dilation by a scale factor of k,

(x, y) → (kx, ky)

Therefore,

A'(x,y) = (1.5·x, 1.5·y)

So the coordinates of the point A' are:

A'(1.5·3, 1.5·2) = (4.5, 3)

Therefore, vertex of point A′ is A′(4.5, 3)

The triangle that have the same shape but not the same size 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.

A graph is a visual representation of data, showing relationships between different variables or values.

Graphs are often used to represent a function, which is a set of inputs and outputs. 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.

It is a branch of mathematics that deals with the occurrence of a random event.

Given a  a binomial trial has a probability of success of 0.2, and 500 trials are performed
