a summer soccer cam ordered a total of 84 soccer balls and t-shirts for the season. Soccer balls cost $25 each and t-shirts cost $9.50 each. if they paid $1,046 total for the purchase, how many of each item was ordered?

Answer:

  0.17

Step-by-step explanation:

You want the probability that a randomly chosen 8th grader will play the guitar.

The table tells us that there are 4 eighth grade students that play the guitar. The total number of eighth grade students is 4+10+6+3 = 23. When one is chosen at random, the probability they play the guitar is ...

  (4 students)/(23 students) = 4/23 ≈ 0.17

The probability an 8th grader will play the guitar is about 0.17.

Answer:

The answer to the linear equation y = 2x + 6 is (x, y) = (1, 2.5). This means that if we plug in x = 1 into the equation, we get y = 2.5.

Step-by-step explanation:

To find the solution to the linear equation y = 2x + 6, we can first rewrite the equation in slope-intercept form. This is done by rearranging the equation to have the form y = mx + b, where m is the slope of the line and b is the y-intercept.

In this case, we have y = 2x + 6. To put this equation in slope-intercept form, we need to isolate the y-term on one side of the equation. We can do this by subtracting 2x from both sides, which gives us y - 2x = 6.

Next, we need to divide both sides of the equation by the coefficient of the y-term, which is -2 in this case. This gives us the equation y = -(1/2)x + 3.

Finally, we can plug in any value of x that we want to find the corresponding value of y. For example, if we plug in x = 1, we get y = -(1/2) * 1 + 3 = 2.5. Therefore, the solution to the equation y = 2x + 6 is (x, y) = (1, 2.5).

In general, if we want to find the solution to a linear equation in slope-intercept form, we can plug in any value of x that we want to find the corresponding value of y. This process is called graphing the line, and it is a useful way to visualize the solutions to linear equations.

To calculate the height of the model, the architect should [divide] the actual height of the building by [10]

The height of the model is [6] inches.

A scale is a factor by which a quantity is multiplied or divided in order to change its magnitude. Scales are commonly used to change the size of a figure without changing its shape or orientation.

Given:

A scale = 1 inch represents 10 feet

The height of the actual building = 60 feet

Since the model is a smaller version of the actual building, in order to get the height of the model, you have to divide the height of the actual building by the scale (10).

Thus,  height of the model = 60/10 = 6 inches

Step-by-step explanation:

because it is an isoceles triangle (both legs are equally long), also both side angles on the baseline must be equally large.

so, we have

4x = 2x + 26

2x = 26

x = 26/2 = 13

f(x) = -Lxl is the function and -3 ≤x≤3 is the domain that could represent the given graph .

What is a function ?

Function is an expression, rule, or law that defines a relationship between one variable (the independent variable) and another variable (the dependent variable).

What is a domain ?

The domain of a function is the set of values that we are allowed to plug into our function. This set is the x values in a function such as f(x). The range of a function is the set of values that the function assumes. This set is the values that the function shoots out after we plug an x value in.

Thus , from the graph it can be clearly depicted that it is representing f(x)=-Lxl for an entire range of  -3 ≤x≤3 .

Hence , f(x) = -Lxl is the function and -3 ≤x≤3 is the domain that could represent the given graph .

The required number of people who voted for yes is 3665.

The ratio can be defined as the proportion of the fraction of one quantity towards others. e.g.- water in milk.

here,

As mentioned in the question,
The people residing in the city voted on whether to raise property taxes. The ratio of yes to no is 5 to 4.

The multiplication of the proportion of yes to the total proportion of total votes gives the number of people who voted for yes.

The ratio of people yes to no = 5:4
Proportion of yes voted people = 5 / 9
The number of people who voted for yes = 5 / 9 × 6597 = 3665.

The linear function that has the greatest initial value is Function C.

Function B has the greatest rate of change.

A function is a relationship between inputs where each input is related to exactly one output.

Example:

f(x) = 2x + 1

f(1) = 2 + 1 = 3

f(2) = 2 x 2 + 1 = 4 + 1 = 5

The outputs of the functions are 3 and 5

The inputs of the function are 1 and 2.

We have,

Function A:

The initial value is o.

f(0) = 0

The rate of change.

= (f(4) - f(2)) / 4 - 2

= (10 - 5) / 2

= 5/2

= 2.5

Function B:

The initial value is

y = 3x - 1

y = 3 x 0 - 1 = 0 - 1 = -1

Let y = f(x)

The rate of change.

= (f(2) - f(1)) / (2 - 1)

= (5 - 2) / 1

= 3

Function C:

The initial value is 2.

(0, 2) is considered as when x = 0, y = 2.

Take two coordinates from the graph.

(3, 3) and (6, 4)

The rate of change.

  4.  (x, y) = (30, 4)

Step-by-step explanation:

You have equilateral triangles in two different configurations, and you want to find the values marked x and y.

All of the angles marked with an arc are congruent, so all are 60°. The angle marked 80° is an external angle to the top/left triangle. Its value is the sum of the values of the remote interior angles:

  80° = 60° +x°

  20° = x° . . . . . . . subtract 60°

  x = 20

The sides of the equilateral triangle are congruent, so all are length 46. That means the right side is ...

  16 +y = 46

  y = 30 . . . . . . . subtract 16

  (x, y) = (20, 30)

All of the angles marked with an arc are congruent, so all are 60°. The top 60° angle of the equilateral triangle is an external angle to the isosceles triangle at top/right. Its two base angles are the remote interior angles with respect to that 60° exterior angle, so their sum is 60°:

  x° +x° = 60°

  x = 30

The two marked legs of the isosceles triangle are both 20, which means all sides of the equilateral triangle are length 20.

  5y = 20

  y = 4 . . . . . . . divide by 5

  (x, y) = (30, 4)

Step-by-step explanation:

Odd numbers exists in AP with common difference of 2.

That is; 1, 2, 5, 7 etc

So lets say the middle number of the three consecutive numbers is x, the next number to it Will be (x+2), and the previous number will be (x-2)

Therefore, the sequence is (x-2), x, (x+2) ... (1)

and the series will be, (x+

-2) + x + (x+2) = 1899

Solve for x;

x + x + x - 2 + 2 = 1899

3x + 0 = 1899

x = 1899 ÷ 3

x = 633

Therefore the consecutive odd numbers (following 1) is: (633 - 2), 633, (633+2) = 631, 633, 635

The parallelogram ABCD with vertices A(-8, 5), B(-7, 8), C(-1,6), and D(-2, 3) is a rectangle as two sides are equal, so option A is correct.

A unique kind of quadrilateral created by parallel lines is called a parallelogram. A parallelogram can have any angle between its neighboring sides, but for it to be a parallelogram, its opposite sides must be parallel.

Given data:

The parallelogram ABCD with vertices A(-8, 5), B(-7, 8), C(-1,6), and D(-2, 3),

Calculate the distance of sides as shown below

[tex]AB = \sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]

AB = [tex]\sqrt{[-7-(-8)]^2 + (8-5)^2}[/tex]

AB =  √(1² + 3²)

AB = √10

Calculate

BC = [tex]\sqrt{[-1-(-7)]^2+(6 - 8)^2}[/tex]

BC = √(36 + 4)

BC = √40 or 2√10

Similarly,

CD = √10

And AD = 2√10

Here AB = CD and BC = AD, opposite sides equal, so it is a rectangle. Therefore, the parallelogram ABCD with vertices A(-8, 5), B(-7, 8), C(-1,6), and D(-2, 3) is a rectangle as two sides are equal.

Consider the logarithmic function:

[tex]f(x)=-1311+306 \ln x[/tex]

Here x is the number of years since 1990 and f(x) is the outpatient surgery as the percent of total surgeries.

The y-intercept of the parabola can be found by verifying if any coordinates from the table has x = 0 and y = some specific value. If there is a coordinate point such that the value of both is x = 0 and y = any value, then the value of y is the y-intercept of the parabola. Further explained in example:

Example: if a line passes through a coordinate point (0, 4), the y-intercept for that line is four because the value of x is 0 and y is 4.

Solving the Problem/Question (Applying the method stated above):

From the table, we can tell that the parabola passes through the following coordinate points: (-2, -11); (-1, -4); (0, 1); (1, 4); (2, 5); (3, 4); (4, 1).
