The fractions ratio of 2.3L of blue paint and 1.7L of yellow paint is equivalent to 23 : 17.

Ratio is defined as the comparison of two quantities of the same units that indicates how much of one quantity is present in the other quantity.

Given is 2.3L of blue paint and 1.7L of yellow paint.

Quantity of Blue paint = Q[B] = 2.3L

Quantity of Yellow paint = Q[Y] = 1.7L

Assume that we represent the fraction ratio of Q[B] and Q[y] by x / y.

Therefore, we can write -

x / y = Q[B] / Q[Y]

x / y = 2.3 / 1.7 = 23/17

In the form of ratio, we can write x : y as 23 : 17.

Therefore, the fractions ratio of 2.3L of blue paint and 1.7L of yellow paint is equivalent to 23 : 17.

Answer:

y = -16

Step-by-step explanation:

Given that,

y varies directly with x. Mathematically, we can write it as follows :

\(y\propto x\)

or

\(y=kx\)

Where

k is constant

Put y = 12 and x = -3 to find k. So,

\(k=\dfrac{y}{x}\\\\k=\dfrac{12}{-3}\\\\k=-4\)

Now put k = -4 and x = 4. So,

\(y=-4\times 4\\\\=-16\)

So, the required value of y is equal to -16.

The given double integral is ∫ ∫ (x² + y²)dx dy, and we need to evaluate it over the region in the positive quadrant where x+y≤1.

To evaluate this double integral, we can first determine the limits of integration for both x and y based on the given region. In the positive quadrant, x and y both range from 0 to 1.

Now, integrating the inner integral with respect to x, we get:

∫ (x² + y²)dx = (1/3)x³ + y²x + C1,

where C1 is the constant of integration.

Next, we integrate the resulting expression with respect to y:

∫ [(1/3)x³ + y²x + C1] dy = (1/3)x³y + (1/3)y³x + C1y + C2,

where C2 is another constant of integration.

Finally, we evaluate this double integral over the given region by substituting the limits of integration:

∫∫ (x² + y²)dx dy = ∫[0 to 1] ∫[0 to 1-x] (x² + y²)dy dx.

Performing the integration, we can find the numerical value of the double integral within the given region.

After polygon STUV is reflected across the y-axis, the coordinates of point S' are (-2, 3).

Reflecting a polygon across the y-axis is a type of transformation in geometry that involves flipping the shape over the y-axis. When reflecting a polygon across the y-axis, the x-coordinates of all the points in the shape are multiplied by -1, while the y-coordinates remain the same.

In the case of polygon STUV, point S has coordinates (2, 3). When reflected across the y-axis, the x-coordinate becomes -2, while the y-coordinate remains 3. Therefore, the image of point S after the transformation, denoted as S', has coordinates (-2, 3).

It's important to note that reflecting a polygon across the y-axis is just one of many possible transformations in geometry. Other common transformations include translations, rotations, and dilations. These transformations can be used to explore the properties of shapes and to solve problems in geometry.

As per the ratio, the number of men on the sight-seeing tour is 4.

In the given sight-seeing tour, we are told that there were 14 people in total. We are also given the ratio of women to children, which is 5 to 2. This means that for every 5 women on the tour, there were 2 children.

To find the number of men on the tour, we need to first find the number of women and children. We can do this by dividing the total number of people by the ratio of women to children.

Let's use a variable to represent the number of sets of 5 women and 2 children. We'll call this variable "x".

So, the number of women on the tour is 5x and the number of children is 2x.

Now, we can set up an equation to find the value of x:

5x + 2x = 14

This equation represents the total number of women and children on the tour, which is equal to 14.

Simplifying the equation, we get:

7x = 14

Dividing both sides by 7, we get:

x = 2

This means that there were 2 sets of 5 women and 2 children on the tour. So, the number of women is:

5x = 5(2) = 10

The number of children is:

2x = 2(2) = 4

Now, we can find the number of men by subtracting the number of women and children from the total number of people:

14 - 10 = 4

The perimeter of the enlarged square is 60 cm, and the area of the enlarged square is 225 cm². The perimeter of a square is equal to the sum of the sides of the square. If the side of the square is x, the perimeter of the square is 4x.

So the perimeter of the original square with side length 6 is:

Perimeter = 4 × 6

             = 24 cm

To find the perimeter of the enlarged square, we need to multiply the original perimeter by the scale factor, which is 2.5. The perimeter of an enlarged square

= 24 × 2.5

= 60 cm.

So, the perimeter of the enlarged square is 60 cm. To find the area of a square, we square the length of one of the sides. So, the area of the original square with side length 6 is:

Area = 6 × 6

= 36 cm²

To find the area of the enlarged square, we need to square the length of one of the sides of the original square and then multiply by the scale factor².

Area of enlarged square = (6 × 2.5)²

                                        = 15²

                                       = 225 cm²

So, the area of the enlarged square is 225 cm².

The given square has a side length of 6 cm. When the square is enlarged using a scale factor of 2.5, we need to find the perimeter and area of the enlarged square. The perimeter of a square is equal to the sum of the sides of the square. So, if the side of the square is x, the perimeter of the square is 4x. The side of the given square is 6 cm. Therefore, the perimeter of the original square is:

Perimeter = 4 × 6

             = 24 cm

To find the perimeter of the enlarged square, we need to multiply the original perimeter by the scale factor, which is 2.5.

Perimeter of enlarged square = 24 × 2.5

= 60 cm.

So, the perimeter of the enlarged square is 60 cm. The area of a square is the product of the length of one side of the square with itself. So, if the side of the square is x, the area of the square is x². The side of the given square is 6 cm. Therefore, the area of the original square is:

Area = 6 × 6

       = 36 cm²

To find the area of the enlarged square, we need to square the length of one of the sides of the original square and then multiply by the scale factor squared.

Area of the enlarged square = (6 × 2.5)²

                                                = 15²

                                               = 225 cm²

Your expected winnings from buying one raffle ticket are approximately $0.38.

To find your expected winnings, we need to calculate the probability of winning each prize and multiply it by the corresponding prize amount. Since you are only buying one ticket, we can calculate the expected winnings as follows:

Expected winnings = (Probability of winning $10) * $10 + (Probability of winning $20) * $20 + (Probability of winning $100) * $100 + (Probability of winning $500) * $500

The probability of winning each prize depends on the total number of tickets sold and the number of tickets available for each prize.

Given that there are 2000 raffle tickets sold and the distribution of prizes, we can calculate the probabilities as follows:

Probability of winning $10 = (Number of $10 prizes) / (Total number of tickets sold) = 2 / 2000 = 0.001

Probability of winning $20 = (Number of $20 prizes) / (Total number of tickets sold) = 2 / 2000 = 0.001

Probability of winning $100 = (Number of $100 prizes) / (Total number of tickets sold) = 2 / 2000 = 0.001

Probability of winning $500 = (Number of $500 prizes) / (Total number of tickets sold) = 1 / 2000 = 0.0005

Now, we can calculate the expected winnings:

Expected winnings = (0.001) * $10 + (0.001) * $20 + (0.001) * $100 + (0.0005) * $500

Expected winnings = $0.01 + $0.02 + $0.1 + $0.25

Expected winnings = $0.38
