At the ice cream shop ,there are 11 shakes sold for every 6 malts .What is the ratio of malts to shakes

Answer:

x = - 1 ± 2[tex]\sqrt{2}[/tex]

Step-by-step explanation:

x² + 2x = 7

solve using the method of completing the square

add ( half the coefficient ot the x- term )² to both sides

x² + 2(1)x + 1 = 7 + 1

(x + 1)² = 8 ( take square root of both sides )

x + 1 = ± [tex]\sqrt{8}[/tex] = ± 2[tex]\sqrt{2}[/tex] ( subtract 1 from both sides )

x = - 1 ± 2[tex]\sqrt{2}[/tex]

The measure of the angle coterminal to - 118° is equal to 242°. (Correct choice: A)

Two angles are coterminal when they have different measures and the same direction in the terminal side. Two consecutive coterminal angles differ their measures in 360°. Then, we can determine the value of the coterminal angle by using the following formula:

θ' = θ + 360°

Where:

If we know that θ = - 118°, then the coterminal angle between 0° and 360° is:

θ' = - 118° + 360°

θ' = 242°

The measure of the coterminal angle is 242°.

By using the concept of Pythagoras Theorem, the result obtained is

Distance between their tops is 13 ft.

What is Pythagoras Theorem?

Pythagoras Theorem states that in a right angled triangle, the square of the hypotenuse is equal to the sum of the squares of perpendicular and base.

The figure has been attached

Let the poles be represented by CD and AE and let AC represents the distance between their tops

Construction

A line from C parallel to DE (shown by a dotted line) is drawn

CD = 10 ft.

AE = 15 ft.

BE = 10 ft.

AB = AE - BE

     = 15 - 10

     = 5 ft.

DE = 12 ft.

BC = 12 ft.

[tex]\angle AED = 90^{\circ}[/tex] [ Angle between pole and ground is 90°]

[tex]\angle ABC = 90^{\circ}[/tex] [ Corrosponding angles are equal]

By Pythagoras Theorem,

[tex]AC^2 = AB^2+BC^2\\AC^2 = 5^2 + 12^2\\AC^2 = 25 + 144\\AC^2 = 169\\AC =\sqrt{169}\\[/tex]

Answer:

y = 1/2x + 4

Step-by-step explanation:

slope-intercept form is: y = mx + b

- x and y are coordinates; if you plug the coordinates into your equation, you should receive a solution.

- m is the slope itself. this can be figured out by calculating the rise/run. look at the point (0,4). the line goes up by one, and right by two. therefore, the slope is 1/2. the line is also going up, so therefore it is a positively sloped line.

- b is the y-intercept, or where the line crosses the y-axis. in this specific example, the line crosses the y-axis at the point (0,4), and therefore the b would be + 4.

so when you put everything together and plug the m and the b into the slope formula, you get y = 1/2x + 4.

The required inequality is x ≥ 94.

What is average?

The middle number, which is determined by dividing the sum of all the numbers by the total number of numbers, is the average value in mathematics. When determining the average for a set of data, we add up all the values and divide this sum by the total number of values.

Add the scores with x and equate them to (82 times 4) as shown:

76 + 80 + 78 + x = (82 times 4)

234 + x = 328

======================================================

Explanation:

We first need to find the slope

[tex](x_1,y_1) = (0,3) \text{ and } (x_2,y_2) = (4,11)\\\\m = \frac{y_{2} - y_{1}}{x_{2} - x_{1}}\\\\m = \frac{11 - 3}{4 - 0}\\\\m = \frac{8}{4}\\\\m = 2\\\\[/tex]

The y intercept is b = 3 due to the point (0,3). This is where the graph crosses the y axis. The y intercept always occurs when x = 0.

Since m = 2 and b = 3, we go from y = mx+b to y = 2x+3

A. The equations are given as follows:

B. The solutions are given as follows: x = 11, y = -5.

C. The angles are given as follows:

The two parallel lines, p and q, are cut by the transversal line, hence angles 2 and 3 are supplementary angles, and thus:

x - 9y + 1 + 11x + 2 = 180

12x - 9y = 177.

Angles 1 and 2 are alternate interior angles, meaning that they are congruent, hence:

6x + y - 4 = x - 9y + 1.

5x + 10y = 5.

x + 2y = 1.

x = 1 - 2y.

Replacing in the first equation, the value of y is given by:

12(1 - 2y) - 9y = 177

33y = -165

y = -165/33

y = -5.

Then the value of x is of:

x = 1 - 2y = 1 + 10 = 11.

Any positive integer n that meets the three requirements is a multiple of 9 and 11, as well as an odd multiple of 5. Lcm(5,9,11)=5911=495 is the smallest such n.

Zero, a positive natural number, or a negative integer denoted by a minus sign are all examples of integers. The inverse additives of the corresponding positive numbers are the negative numbers.

Here,

The n subsequent integers from -(n-1)/2 to (n+1)/2 have a sum of 0 if n is an odd number. Sum n is produced by translating the interval to the right by 1. Each positive sum is therefore a positive multiple of n.

If n is even, the sum of the next n even integers from -n/2-1 to +n/2 is n/2. Sum n+n/2 is produced by moving the interval to the right by 1. As a result, every positive sum is an odd multiple of n/2.

Therefore, any positive integer n that meets the three requirements is a multiple of 9 and 11, as well as an odd multiple of 5. Lcm(5,9,11)=5911=495 is the smallest such n.

What is a fraction?

If the numerator is bigger, it is referred to as an improper fraction and can also be expressed as a mixed number, which is a whole-number quotient with a proper-fraction remainder.

Any fraction can be expressed in decimal form by dividing it by its denominator. One or more digits may continue to repeat indefinitely or the result may come to a stop at some point.

Cye-Na is starting a juice stand. It takes her 15 minutes to prepare 3 1/4 cups of juice.

So in 15 minutes, she makes 13/4 cups of juice.

So for 1 cup she will take 15/ (13/4) minutes.

For 32 1/2 cup she will take 15 * (65/2)/ (13/4)

Increasing the launch angle increases the maximum height. Increasing the launch angle increases the time of flight.

The starting vertical velocity determines the time in the air. Increasing the launch angle lengthens the duration in the air because steeper launch angles have a larger vertical velocity component.

The height of release and the angle of release is related. -The angle of release decreases as release height increases. - The angle of release rises as the height of release falls.

We observe that the projectile's maximum height is dependent on both initial speed and the angle of projection (), just as it is in the case of flight time. The projectile will rise to a larger height if its initial velocity is higher and its angle of projection from the horizontal is greater.

To use the delta method to approximate the standard error for the square root of the sample average g, we first need to calculate the sample average g.

A variation from precision or correctness is called an error. An error, then, is a mistake or a failure to perform an action appropriately. Errors can take place  person commits a calculation error, an equipment breaks down, or a person interprets information incorrectly.

Various factors might lead to errors. For instance, a person may make a mathematical error because they misunderstood the problem or made an error when doing the computation. A machine may break down due to a design error, normal wear and tear, or an outside event like a power loss. A person's prejudice may cause them to interpret information incorrectly.

How to solve?

This can be done by summing all the values in the sample and dividing by the total number of values in the sample. Next, we need to find the derivative of the function that describes the square root of the sample average g. This derivative will be used to approximate the standard error. To find the standard error, we then multiply the derivative by the standard deviation of the sample average g. This will give us an approximation of the standard error for the square root of the sample average g. It is important to note that this approximation will only be accurate if the sample is normally distributed and the sample size is large. Additionally, the delta method is only one way to approximate the standard error, and other methods may be more appropriate in certain situations.
