Last week, Cindy's Diner sold 7 milkshakes with whipped cream on top and 18 milkshakes without whipped cream. What percentage of the milkshakes had whipped cream?

Answers

Answer 1

Answer:  The total number of milkshakes sold is 7 + 18 = 25.

The number of milkshakes sold with whipped cream is 7.

To find the percentage of milkshakes with whipped cream, we can use the formula:

percentage = (part/whole) x 100

Substituting the values, we get:

percentage = (7/25) x 100

percentage = 28

Therefore, 28% of the milkshakes had whipped cream.

60 D A B Diagram NOT accurately drawn The sides of an equilateral triangle 1BC and two regular polygons meet at the point 4. AB and AD are adjacent sides of a regular 10-sided polygon. AC and 4D are adjacent sides of a regular n-sided polygon Work out the value of n.

Answers

The value of n in the n-sided polygon, with sides AC and AD, where the external angle formed at the point the decagon touches the n-sided polygon is 60° is; n = 15

What is a polygon?

A polygon is a planar shape with three or more straight sides.

The sum of angles at a point property indicates that, the sum of angles at the point A can be presented as follows;

∠BAC + ∠CAD + ∠DAB = 360°

Angle ∠BAC = 60°

Angle ∠DAB is an interior angle of a 10-sided regular polygon, (a decagon),  therefore, the measure of angle ∠DAB is 144°

Plugging in the values of the measures of the angles ∠BAC and ∠DAB, in the equation, ∠BAC + ∠CAD + ∠DAB = 360°, we get;

+ ∠CAD + 144° = 360°

∠CAD = 360° - (144° + 60°) = 156°

∠CAD = 156°

The formula for finding the measure of the interior angle of an n-sided polygon, θ, can be presented as follows;

θ = (n - 2) × 180°/n

Where the interior angle, θ = 156°, which is the measure of ∠CAD, in the n-sided polygon, we get;

156° = (n - 2) × 180°/n

156·n = 180·n - 360

360 = 180·n - 156·n = 24·n

n = 360/24 = 15

The number of sides in the n-sided polygon is 15, therefore, AC and AD are adjacent to a 15-sided polygon

1. The value of Z is 1.96 determined from Z-table or a calculator. 2. The confidence interval equation is 161 ± 1.96* (4/√20). 3.The standard error is 0.8944. 4. The margin of error is 1.754. 5. The upper and lower limits are 162.754 and 159.246 respectively. 6. Confidence interval indicate how confident the researchers is that true mean is within the range.

1. For a 95% confidence interval, the value for Z is 1.96. This value is found by looking at a Z-table or using a calculator to find the Z-score that corresponds to a 95% confidence level.

2. The confidence interval equation is:

CI = x ± Z* (σ/√n)

Where x is the sample mean, Z is the Z-score, σ is the sample standard deviation, and n is the sample size.

Plugging in the values from the question, we get:

CI = 161 ± 1.96* (4/√20)

3. The standard error is calculated by dividing the sample standard deviation by the square root of the sample size:

SE = σ/√n = 4/√20 = 0.8944

4. The margin of error is calculated by multiplying the Z-score by the standard error:

ME = Z*SE = 1.96*0.8944 = 1.754

5. The upper and lower limits are calculated by adding and subtracting the margin of error from the sample mean:

Upper limit = x + ME = 161 + 1.754 = 162.754

Lower limit = x - ME = 161 - 1.754 = 159.246

6.  The 95% confidence interval for the mean drug price is between $159.246 and $162.754. This means that we are 95% confident that the true mean price of the drug is within this range.

The sum of two numbers is 12. Their difference is 6. The second number is double the first number. Create a linear system to solve the two numbers.

Answers

We are being informed that the sum of the two numbers is 12 and their difference is 6.

Thus, the two numbers whose sum is equal to 12 and their difference is equal to 6 are 9 and 3 respectively.

Let those two unknown numbers be (a) and (b)

a + b = 12

Their difference;

i.e.

a - b = 6

So, we can equate the two equations together:

i.e.

a + b = 12     --- (1)

a - b = 6        --- (2)

From equation (1); Let a be:

a = 12 - b

Now, Let's replace the value of (a) into equation (2)

12 - b - b = 6

12 - 2b = 6

-2b = 6 - 12

-2b = -6

2b = 6

b = 6/2

b = 3

If b = 3;

Then from equation, we have:

a + b = 12

replace b with 3 from the above equation, we have:

a + 3 = 12

a = 12 - 3

a = 9

Therefore, we can conclude that the sum of the two numbers are 9 and 3. respectively

So the equation of the line in slope-intercept form is y = x + 2. The y-intercept is 2.

What is linear equation ?

Linear equation can be defined as equation in which highest degree is one.

In this problem, you are given a graph of a linear function. The graph shows two points on the line: (-2, 0) and (3, 5).

To find the slope of the line, we can use the formula:

slope = (change in y) / (change in x)

We can use the two points given to find the change in y and the change in x:

change in y = 5 - 0 = 5

change in x = 3 - (-2) = 5

Plugging these values into the formula, we get:

slope = 5/5 = 1

So the slope of the line is 1.

To find the y-intercept of the line, we can use one of the points on the line and the slope we just found. Let's use the point (-2, 0):

y - y1 = m(x - x1)

where (x1, y1) is the point (-2, 0) and m is the slope we just found:

y - 0 = 1(x - (-2))

y = x + 2

Therefore, the equation of the line in slope-intercept form is y = x + 2. The y-intercept is 2.

To find the p-value, we need to use the standard normal table or a calculator with a normal distribution function. The p-value is the probability of observing a test statistic as extreme or more extreme than the one observed, given that the null hypothesis is true.

In this case, we are looking for the probability that z is greater than or equal to 1.12, given that the null hypothesis is true.

Using a standard normal table, we can find the area to the left of z=1.12, which is 0.8686. However, we are interested in the area to the right of z=1.12, which is 1 - 0.8686 = 0.1314.

What is the volume of a right cone?

The area or volume occupied by a right circular cone is referred to as the right circular cone's volume. A three-dimensional solid object called a right circular cone has a pointed end on one side and a circle on the other. The vertex of the cone is another name for the sharp end. A cone with a right circular shape is one whose axis is parallel to the base plane.

Here, we have

Given: The volume of a right cone is 2016\piπ units^3. If its diameter measures 24 units

Height of the cone = Volume of a cone ÷ 1/3(πr²)

Where:

π = 22/7

r = radius = diameter / 2 = 24 / 2 = 12 units

h = height

2016π÷ (1/3 x π x 12²) = 42 units

The difference quotient [f(x+h)-f(x)]/h for the function f(x)=-5x-1 is -5.

To find and simplify the difference quotient [f(x+h)-f(x)]/h for the function f(x)=-5x-1, we need to substitute (x+h) into the function for x and then simplify.

First, let's substitute (x+h) into the function for x:
f(x+h) = -5(x+h) - 1

Next, let's simplify:
f(x+h) = -5x - 5h - 1

Now, let's subtract f(x) from f(x+h):
[f(x+h) - f(x)] = (-5x - 5h - 1) - (-5x - 1)

Simplifying further:
[f(x+h) - f(x)] = -5h

Finally, let's divide by h:
[f(x+h) - f(x)]/h = -5h/h = -5

A is reflected over the x-axis to create A'. Then, points A, A', B and a fourth point become the vertices of a rectangle. What are the coordinates of the fourth point?



(3, -5)
(-6, -5)
(6, 5)
(-3, -5)

Answers

The fourth point has coordinates (-17, 0).

The x-coordinate of A remains constant but the sign of the y-coordinate changes if A is mirrored over the x-axis to form A'. Hence, if Has a coordinates (a, b), A' must also have coordinates (a, -b).

Given that A and A' are the corners of a rectangle that are opposite one another, the other two corners of the rectangle must be on a horizontal line that passes through A and A"s midpoint (a, 0). Since (a, 0) and the fourth point (let's call it C) are separated by 2|b|, the distance between A and A' is also 2|b|. This indicates that depending on which side of the line AA' C is on, it has coordinates of (a + 2|b|, 0) or (a - 2|b|, 0).

In this instance, the coordinates of A are (3, 5) and those of A' are (3, -5). The intersection of A and A' is (3, 0). A and A' are separated by 2|5|, which equals 10.

The fourth point, C, thus, has coordinates of either (3 + 2(10), 0) = (23, 0) or (3 - 2(10), 0) = (-17, 0).

The right response is (3 - 2(10), 0), which can be deduced from the graph since the rectangle is symmetric about the y-axis (-17, 0).

The fourth point therefore has coordinates (-17, 0).

[tex]f = \frac{mv {}^{2} }{gr} [/tex]

Answers

g can be made the subject of the formula as g = mv² / fr.

What is Subject of a Formula?

Subject of a formula is defined as the variable that we are going to find. This can be differentiated by putting in one side of the formula.

The given formula is,

f = mv² / gr

Here, f is the subject of the formula, as it is the only variable in the left hand side.

Now rearrange the equation that g is isolated in the left hand side.

Multiply both sides by gr.

f g r = mv²

g (fr) = mv²

Divide both sides by fr.

g = mv² / fr

Hence we can rearrange the formula as g = mv² / fr.

What is mean by Rectangle?

A rectangle is a two dimension figure with 4 sides, 4 corners and 4 right angles. The opposite sides of the rectangle are equal and parallel to each other.

Given that;

Two angles of a quadrilateral measure 180° and 50°.

And, The other two angles are in a ratio of 2:11.

Since, The other two angles are in a ratio of 2:11.

Hence, ,Measures of both angles are, 2x and 11x.

Now, We know that;

Sum of all interior angles of a quadrilateral are 360°.

Hence, We get;

⇒ 180 + 50 + 2x + 11x = 360

⇒ 230 + 13x = 360

⇒ 13x = 360 - 230

⇒ 13x = 130

⇒ x = 10

Thus, Measures of both angles are,

2x = 2 × 10 = 20°

and 11x = 11 × 10 = 110°
