Answer:

Option (c) $30.00

Explanation:

Let the original price be $x

Given the rate of discount is 40%

Selling (or sale) price of the book is = $18

The original price is calculated by the formula,

Selling Price = Original Price(1 – r%)

Substituting the values in the above equation,

[tex]18 = x (1-\frac{40}{100})[/tex]

[tex]18 = x (\frac{60}{100})[/tex]

[tex]x=\frac{1800}{60}[/tex]

Therefore, x = 30

Hence, option (c)is correct

The original price of the book was $30.00, which, after a 40% discount, results in the $18.00 sale price. To find the original price, divide the sale price by 0.60 (which represents the remaining 60% after the discount). So the correct option is C.

To find the original price of the book before the sale, you need to consider that the sale price represents 60% of the original price, because the book was discounted by 40%. The calculation that needs to be done is to divide the sale price by 0.60.

Here are the steps:

Therefore, the original price of the book was $30.00.

Answer:

[tex]4\dfrac{3}{8}[/tex] cups of flour

Step-by-step explanation:

A muffin recipe, which yields 12 muffins, calls for 2/3 cup of milk for every 1 3/4 cups of flour.

Then this recipe, which yields one muffin, calls for

[tex]\dfrac{2}{3}:12=\dfrac{2}{3}\cdot \dfrac{1}{12}=\dfrac{1}{18}[/tex]

cup of milk for every

[tex]1\dfrac{3}{4}:12=\dfrac{7}{4}\cdot \dfrac{1}{12}=\dfrac{7}{48}[/tex]

cups of flour.

Thus,

this recipe, which yields a batch of 30 muffins, calls for

[tex]\dfrac{1}{18}\cdot 30=\dfrac{5}{3}=1\dfrac{2}{3}[/tex]

cups of milk for every

[tex]\dfrac{7}{48}\cdot 30=\dfrac{210}{48}=\dfrac{35}{8}=4\dfrac{3}{8}[/tex]

cups of flour.

Final answer:

To calculate the amount of flour needed to yield 30 muffins, we first find the amount of flour required for a single muffin and then scale it up to 30 by multiplying. For 30 muffins, approximately 1.094 cups of flour are required based on the original recipe ratios.

Explanation:

The question involves the use of ratios to calculate the amount of a particular ingredient required for a different quantity of the final product. Since the original recipe yields 12 muffins with 1 3/4 cups of flour, we first need to determine how much flour is needed for one muffin by dividing 1 3/4 cups by 12. After finding the flour quantity per muffin, we then multiply that by 30 to find out how much flour is needed for 30 muffins.

Step 1: Calculate the amount of flour for one muffin.
Amount of flour per muffin: 1 3/4 cups / 12 =
7/4 cups / 12 = 7/48 cups per muffin.

Step 2: Calculate the amount of flour needed for 30 muffins.
Amount of flour for 30 muffins: 7/48 cups per muffin x 30 = 7/48 x 30 =
52.5/48 or approximately 1.094 cups of flour.

In a triangle, the point where the medians intersect, known as the centroid, divides each median into two segments in a 2:1 ratio. In this context, only the measurement of segments 3 and 6 fit this property.

The median of a triangle is a segment joining a vertex to the midpoint of the opposite side. In this question, we are considering segments of a median, so we're considering the vertex of the triangle to the centroid (where medians intersect) and from the centroid to the midpoint of the opposite side.

The key property of medians in a triangle is that the centroid, or point of intersection, divides each median into two segments in the ratio 2:1. This means the distance from a vertex to the centroid is twice the distance from the centroid to the midpoint of the opposite side.

From the provided segments, only 3 and 6 fit this principle. This means the distance from the vertex to the centroid is 3 (representing two-thirds of the median) and the distance from the centroid to the midpoint of the opposite side is 6 (representing one-third of the median).

Mix a pthalo green and alizarin crimson with ultramarine blue

This new mixture will contain 2 cups of yellow and 7 cups of blue, resulting in a bluer shade of green compared to the original mixture.

To create a bluer shade of green, we need to increase the proportion of blue relative to yellow in the mixture. We can achieve this by increasing the amount of blue while keeping the amount of yellow constant.

Given that the original mixture ratio is 2 cups of yellow to 3.5 cups of blue, let's increase the amount of blue relative to yellow. We can try doubling the amount of blue while keeping the amount of yellow constant.

So, to create a bluer shade of green, we can use:

- 2 cups of yellow (constant)

- 2 * 3.5 = 7 cups of blue

This new mixture will contain 2 cups of yellow and 7 cups of blue, resulting in a bluer shade of green compared to the original mixture.

A type of green paint is made by mixing 2 cups of yellow with 3.5 cups of blue. Find a mixture that will make the different shade of green that is bluer

Answer:

The length of one side of the square base is 24 feet.

Step-by-step explanation:

Given:

Volume of square pyramid(V) = 3969 cubic feet, and its height(h) = 21 feet.

Now, we need to find the length of one side(a) of the square base.

So. by putting the formula of square pyramid we get our length of one side(a):

[tex]V=a^{2}\frac{h}{3}[/tex]

[tex]3969=a^{2}\times \frac{21}{3}[/tex]

[tex]3969= a^{2}\times 7[/tex]

Dividing both sides by 7 we get:

[tex]567=a^{2}[/tex]

Using square root both sides we get:

[tex]23.81=a[/tex]

a = 24 feet (approximately).

Therefore, the length of one side of the square base is 24 feet.

The length of one side of the square base of the pyramid is approximately 23.8 feet. This was determined using the volume formula for a square pyramid and solving for the side length. The base area and height were key in finding this solution.

To find the length of one side of the square base of the pyramid, we can use the formula for the volume of a square pyramid:

Volume = (1/3) × Base Area × Height

Given:

Let the side length of the square base be s feet. The base area of the square is s².

Using the volume formula, we get:

3969 = (1/3) × s² × 21

First, solve for s²:

3969 = 7 × s²

s² = 3969 / 7

s² = 567

Now, take the square root of both sides to find s:

s = √567 ≈ 23.8 feet

Therefore, the length of one side of the square base of the pyramid is approximately 23.8 feet.

from the provided focus point and directrix, we can see that the focus point is above the directrix, meaning is a vertical parabola and is opening upwards, thus the squared variable will be the "x".

Final answer:

The equation of the parabola with a focus of (7,9) and a directrix of y = 5 can be written as (x-7)^2 = 16(y-5).

Explanation:

The equation of a parabola in standard form is given by:

(x-h)^2=4p(y-k)

Where (h,k) is the vertex of the parabola and p is the distance from the vertex to the focus and to the directrix. In this case, the focus is (7,9) and the directrix is y = 5. To find the equation of the parabola, we need to determine the value of p.

From the given information, we can see that the focus is a point on the parabola and the directrix is a line that is perpendicular to the axis of symmetry and does not pass through the vertex. Therefore, the distance from the vertex to the focus is equal to the distance from the vertex to the directrix. In other words, the value of p is the distance from the vertex to the line y = 5.

Since the directrix is a horizontal line, the vertex of the parabola is on the line y = 5. Therefore, k = 5. The distance from the vertex to the line y = 5 is equal to the distance from the vertex to the focus, which is p. Therefore, we have:

p = 9 - 5 = 4

So the equation of the parabola is:

(x-7)^2 = 4 * 4(y-5)

Simplifying, we get:

(x-7)^2 = 16(y-5)

Therefore, the equation of the parabola is (x-7)^2 = 16(y-5).

Answer:

the answer is MQA =130°

Wen u draw a parallel line with respect to MD through Q, the angle between the line become 40 degree - alternate angles

so the rest is 90 degree, therefore 90 + 40 = 130 degree

Answer:

∠MQA = 130°

Step-by-step explanation:

∠MDQ = 90° ( angle between tangent and radius )

Given ∠QMD = 40°, then

∠MQD = 180° - (90 + 40)° = 180° - 130° = 50° ( sum of angles in a triangle )

∠MQD and ∠MQA form a straight angle and are supplementary, thus

∠MQA = 180° - 50° = 130°

OR

The external angle of a triangle is equal to the sum of the 2 opposite interior angles

∠MQA is an exterior angle of the triangle, thus

∠MQA = 90° + 40° = 130°

Step-by-step explanation:

so the formula for a circle is πr^2, and a semicircle is half of a circle....... so we do the formula of a circle, πr^2, divided by 2 to get the area of it, πr^2/2. now we kind of do the same thing for perimeter. we do the circumference/2, so 2πr/2, or πr but we need to add the bottom of the semicircle so we add 2r to it . so this whole equation would be πr+2r.

A factor of f(x) is (x + 1) must be true ⇒ 2nd answer

Step-by-step explanation:

In a quadratic equation y = ax² + bx + c, the roots of it are:

∵ -1 is a root of f(x)

∵ The roots of f(x) are the values of x when f(x) = 0

∴ At f(x) = 0, x = -1

When f(x) = 0, then all factors of f(x) must be equate by 0

∵ f(x) = 0

∵ x = -1 ⇒ when f(x) = 0

- Add to sides by 1

∵ x + 1 = 0

∴ (x + 1) is one factor of f(x)
