Final answer:

To find the number of sliders and chicken wings in the combination meal, set up a system of equations and solve. There are 2 sliders and 10 chicken wings in the combination meal.

Explanation:

In order to find the number of sliders and chicken wings in the combination meal, we can set up a system of equations. Let's assume that the number of sliders is 's' and the number of chicken wings is 'c'. We know that each slider has 250 calories and each chicken wing has 60 calories. The total number of sliders and chicken wings in the combination meal is 12, so we have the equation s + c = 12.

We also know that the total number of calories in the combination meal is 1100. Since each slider has 250 calories and each chicken wing has 60 calories, we can write the equation 250s + 60c = 1100.

Now we can solve this system of equations to find the values of 's' and 'c'.

Multiplying the first equation by 60, we get 60s + 60c = 720. Subtracting this equation from the second equation, we get 250s - 60s = 1100 - 720, which simplifies to 190s = 380. Dividing both sides by 190, we find that s = 2.

Substituting this value back into the first equation, we have 2 + c = 12. Solving for 'c', we find that c = 10.

Therefore, there are 2 sliders and 10 chicken wings in the combination meal.

Answer:

The answer is 525

Answer:

Option B. 525 students.

Step-by-step explanation:

The school enrollment for Oakwood Elementary is shown in the graph.

The given graph is representing a linear function. So we will form the function first to calculate the enrollment in 2012.

Equation of the given line in the graph will be in the form of y = mx + c

where m is the slope and c = y- intercept

y-intercept = 300

this line passes through two ordered pairs (0, 300) and (1, 325)

Now the slope m = [tex]\frac{y-y'}{x-x'}[/tex]

m = [tex]\frac{325-300}{1-0}=25[/tex]

Therefore, equation representing the situation will be y = 25x + 300

Now we will put the value of x = year 2012 - year 2003 = 9 years

y = 25×9 + 300

y = 225 + 300

y = 525

Option B. 525 is the correct option.

Answer:

171 sq units.

Step-by-step explanation:

Since you don't specify you want a the side surface area only, we'll calculate both.

First, the base...

We have a square with a side of 9 units.

Area of the base is then 9 x 9 = 81 sq units.

For the sides, we have 4 triangles with a base of 9 and a height of 5 units.

The area of a triangle is calculated with A = (b * h)/2

So, each of the sides of the pyramid has an area of:

A = (9 * 5) / 2 = 22.5 sq units

There are four sides, so total lateral area: 4 * 22.5 = 90 sq units.

Total area: 81 + 90 = 171 sq units.

Answer:

Step-by-step explanation:

If you're given a line, determine its slope.

Any parallel line you construct must have the same slope as does the given line.

Any perpendicular line you construct must have a slope which is the negative reciprocal of the slope of the given line.

Parallel lines have the same slope.

And perpendicular lines have negative reciprocal slopes. Ex. 2/3 x and -3/2x

Answer:

1st pic: Answer is 3

2nd pic: Answer is 5

3rd pic: Answer 4

Step-by-step explanation:

For this case we have the following equation:

[tex]\frac {1} {4} (8-4p) + 2p = 12[/tex]

We apply distributive property to the terms within parentheses.

[tex]\frac {8} {4} - \frac {4p} {4} + 2p = 12\\2-p + 2p = 12\\2 + p = 12[/tex]

Subtracting 2 on both sides of the equation:

[tex]p = 12-2\\p = 10[/tex]

ANswer:

[tex]p = 10[/tex]

Answer:

p = 10

Step-by-step explanation:

1\4(8 - 4p) + 2p = 12

8 - 4p/4 + 2p = 12

8 - 4p + 8p/4 = 12

8 + 4p = 12 × 4

4p = 48 - 8

4p = 40

p = 40/4

p = 10

Thus, the value of p is 10

Answer:

always increasing

Step-by-step explanation:

When you look at the graph from left to right on the x-axis the y-axis is always increasing in value.

The graph in question is a line graph, used to show correlations between two variables on a horizontal and vertical axis. Other graph types include bar graphs, for comparing different categories of data, and pie charts, for representing parts of a whole. The third exam vs final exam graph demonstrates a good model of linearity with little deviation.

The description best fitting the graph in this instance is that of a line graph. Line graphs are used to show the correlation between two variables, one on the horizontal axis and one on the vertical axis. They are most appropriate when trying to communicate trends, such as increases, decreases, or consistency over a period of time.

Another type of graph is a bar graph, which is most effective when comparing different categories of data. For example, comparing the amount of rainfall each month can be appropriately represented using a bar graph. Finally, a pie chart displays proportional relationships in the data and is best used when representing parts of a whole, such as voters' preferences in an election.

Referring back to the graph about the third and final exams, it could be said that the line of best fit models the data well, where there appears to be little deviation from the line. By analyzing the graphs carefully, it is possible to draw meaningful conclusions and compare data accurately.

Answer:

[tex]cos(C) =\frac{40}{41}\\\\cos(C)=0.976[/tex]

Step-by-step explanation:

To find the [tex]cos (C)[/tex] we must use the cosine theorem.

The cosine theorem says that:

[tex]c^2 = a^2 +b^2 -2abcos(C)[/tex]

In this case:

Step-2 : Find two factors of  15  whose sum equals the coefficient of the middle term, which is   8 .

     -15    +    -1    =    -16

     -5    +    -3    =    -8

By copairing it with x^2+y^2+2gx+2fy+c=0, we get,

2g=p or, g=p/2

2f=6 or, f=3

c=-3

now the radius is,

r^2=g^2+f^2-c

or, 4^2=(p/2)^2 +3^2 -(-3)

or, 16= p^2/4 +9+3

or, 16-9-3=p^2/4

or p^2/4=4

or, p^2=4×4

or p^2=4^2

or p=4

therefore the rewuired value of p is 4.

Answer:

Possible values are 4 and -4.

Step-by-step explanation:

First complete the square on the x and y terms:

x^2 + y^2 + px + 6y - 3 = 0

(x + 0.5p)^2 - 0.25p^2 + (y + 3)^2 - 9 - 3 = 0

(x + 0.5p)^2 + (y + 3)^2 = 12 + 0.25p^2

This is the standard form of the equation of the circle where the right side = radius^2 so we can write:

12 + 0.25p^2 = 4^2

0.25p^2 = 16 - 12 = 4

Taking square roots:-

0.5p = +/- 2

p = 2 / 0.5 , -2 / 0.5

p = 4, -4.

Answer:

The distance between the center and the foci is √13 ≅ 3.6 units

Step-by-step explanation:

* Lets revise the equation of the ellipse

- The standard form of the equation of an ellipse with center

  (0 ,  0) and major axis parallel to the x-axis is

x²/a² + y²/b² = 1

# a  >  b

- The length of the major axis is 2a

- The coordinates of the vertices are  (± a , 0)

- The length of the minor axis is 2b

- The coordinates of the co-vertices are (0 , ± b)

- The coordinates of the foci are  (± c , 0), where c² =  a² −  b²

* Lets solve the problem

∵ The equation is x²/49 + y²/36 = 1

∴ a² = 49

∴ b² = 36

∵ The coordinates of the foci are (± c  , 0)

∵  c² = a² − b²

∴ c² = 49 - 36 = 13 ⇒ take square root for both sides

∴ c = ± √13

∴ The foci are (√13 , 0) and (-√13 , 0)

∵ The center is (0 , 0)

∴ The distance between the center and the foci is c - 0 = c or

   0 - (-c) = c

∴ The distance between the center and the foci = √13 - 0 = √13 units

* The distance between the center and the foci is √13 ≅ 3.6 units

The distance of the foci from the center of the ellipse given by the equation [tex]x^{2/49} + y^{2/36}[/tex] = 1 is approximately 3.61 units.

To find the distance of the foci from the center of the ellipse given by the equation  [tex]x^{2/49} + y^{2/36}[/tex] = 1, we use the formula for the focal distance in an ellipse: c = √(a² - b²).

Here, a² is the larger denominator, which is 49, and b² is the smaller denominator, which is 36. Therefore:

Now, calculate the focal distance:

c = √(a² - b²) = √(49 - 36) = √(13) ≈ 3.61

Thus, the foci are approximately 3.61 units away from the center of the ellipse.

the correct answer is b.33

Answer:

b

Step-by-step explanation:

The correct option is C.

Carlos can make 4 different burgers by choosing between beef or turkey and wheat or white roll.

To calculate the number of different burgers Carlos can make, we'll use the fundamental principle of counting.

Step 1: Determine the number of options for the type of burger. Carlos can choose either beef or turkey, so there are 2 options.

Step 2: Determine the number of options for the type of roll. Carlos can choose either wheat or white, so there are 2 options.

Step 3: Multiply the number of options for each step together to find the total number of combinations.

Number of burger options × Number of roll options = Total combinations

2 options for type of burger × 2 options for type of roll = 4 total combinations

So, Carlos can make 4 different burgers.
