The required weight of fido the labrador is 40 kilogram.

kilogram is the fundamental unit used to measure weight ans pound is used in UK to measure weight of any object.

As we have given in 10 kilogram, there are 22 pounds. So, one kilogram is equal to 2.2 pound.

We have to find the weight of fido the labrador in kilogram

here,weight in pound is 88

we know that one pound contain 1/2.2 kilogram

So, weight of 88 pound in kilogram = (88)1/2.2

weight in kilogram = 40 kilograms.

Hence, the required answer is 40 kilogram.

The factor of quadratic equation is x√17

A quadratic equation is one that contains a second-degree polynomial. They are extensively utilized in a wide range of disciplines, including engineering, architecture, finance, biology, and, of course, mathematics.

Factoring is frequently the simplest way to solve a quadratic equation. Finding expressions that can be multiplied together to get the expression on one side of the problem is the process of factoring. A quadratic equation is represented as a product of linear terms if it can be factored.

First you need to find perfect square factors of 17

17 = 1*17

√17  = √1*√17 = 1√17 = √17

we had also √x² = x

So the answer is x√17

By definition of area of a rectangule,  the width of the field is 2/3 mile.

The area is the measure of a space delimited by a contour called the perimeter. In other words, area is the measure of the surface of a figure; that is, the measure of its interior region.

A rectangle is a flat geometric figure with four sides, of which two sides that are opposite parallel to each other have the same length and the remaining two have another length.

The area of ​​a rectangle is calculated from the two different sides, and it is calculated by multiplying the length (L) by the width (W):

Area= L×W

In this case, the length of a rectangular shaped field is 3/4 mile. If the area of the field is 1/2 mile², then the width can be calculated as:

1/2 mile²= 3/4 mile× W

Solving:

1/2 mile²÷ 3/4 mile= W

2/3 mile= W

Finally, the width of the field is 2/3 mile.

The greatest length that Wendy can make the pieces of thread is 4 feet.

In order to produce many pieces of bread that are all the same length, Wendy needs to cut the threads into equal lengths.

To find the greatest length that she can make, we need to find the greatest common factor (GCF) of 80 and 12.

The GCF of 80 and 12 is 4. This means that Wendy can cut both threads into pieces that are 4 feet long.

For the 80-foot thread, she can cut it into 20 pieces that are 4 feet long (80/4=20).

For the 12-foot thread, she can cut it into 3 pieces that are 4 feet long (12/4=3).

Therefore, the greatest length that Wendy can make the pieces of thread is 4 feet.

In conclusion, by finding the GCF of the lengths of the two threads, we can determine the greatest length that Wendy can make the pieces of thread. In this case, the greatest length is 4 feet.

Answer:

x ≈ 0.67

Step-by-step explanation:

\(15(3)^2x = 90\\\\15(9)x = 90\\\\135x = 90\\\\x = 90/135\\\\ x = 2/3\\\\x = 0.666...\\\\x = 0.67 \ (rounded \ to \ nearest \ hundredth )\)

The differentiation  is y' = [(1/x) - 15x^4y^2] / [6x^5y - (2y/x)].

To find y' using implicit differentiation, we first need to take the derivative of both sides of the equation with respect to x. This means we will be treating y as a function of x and using the chain rule when taking the derivative of the terms involving y.

Starting with the left-hand side, we have:

d/dx (3x^5y^2) = 15x^4y^2 + 6x^5y * (dy/dx)

For the right-hand side, we will need to use the product rule and the chain rule:

d/dx (In(xy^2)) = (1/xy^2) * (y^2 * (dx/dx) + x * 2y * (dy/dx))
                 = (1/x) + (2y/x) * (dy/dx)

Combining the derivatives from both sides, we get:

15x^4y^2 + 6x^5y * (dy/dx) = (1/x) + (2y/x) * (dy/dx)

Simplifying and solving for y', we get:

y' = [(1/x) - 15x^4y^2] / [6x^5y - (2y/x)]

Answer:

SA = 94 ft²

Step-by-step explanation:

To find the surface area of a rectangular prism, you can use the equation:

SA = 2 ( wl + hl + hw )

SA = surface area of rectangular prism

l = length

w = width

h = height

In the image, we are given the following information:

l = 4

w = 5

h = 3

Now, let's plug in the information given to us to solve for surface area:

SA = 2 ( wl + hl + hw)

SA = 2 ( 5(4) + 3(4) + 3(5) )

SA = 2 ( 20 + 12 + 15 )

SA = 2 ( 47 )

SA = 94 ft²

Answer:

y=-x+2

Step-by-step explanation:

The slope-intercept form is y=mx+b where m is the slope and b is the y-intercept.

From the graph, we can see that the y-intercept is at (0,2) so the equation becomes y=mx+2.

Other points on the graph include (1,1) and (2,0). Plugging (1,1) into the slope-intercept equation, we get 1=(m)1+2. Solving this will give us m=-1.

We can confirm this by plugging m=-1 into the equation along with the point (2,0); 0=(-1*2)+2. It checks out!

So our final equation in slope-intercept form will be y=-x+2

Answer: Think it is y=2x+2

Step-by-step explanation:

The probability that the second card is a jack given that the first card was a 2 is 52/51.

To calculate the probability that the second card is a jack given that the first card was a 2, we need to consider the remaining cards in the deck after the first card is drawn.

When the first card is drawn and it is a 2, there are 51 cards remaining in the deck, out of which there are 4 jacks.

The probability of drawing a jack as the second card, given that the first card was a 2, can be calculated using conditional probability:

P(Second card is a jack | First card is a 2) = P(Second card is a jack and First card is a 2) / P(First card is a 2)

Since the first card is already known to be a 2, the probability of the second card being a jack and the first card being a 2 is simply the probability of drawing a jack from the remaining 51 cards, which is 4/51.

The probability of the first card being a 2 is simply the probability of drawing a 2 from the initial deck, which is 4/52.

P(Second card is a jack | First card is a 2) = (4/51) / (4/52)

Simplifying the expression:

P(Second card is a jack | First card is a 2) = (4/51) * (52/4)

P(Second card is a jack | First card is a 2) = 52/51

The area of the parallelogram with vertices (0,0), (3,6), (8,2), and (11,8) is 0 square units.

To find the area of a parallelogram with given vertices, we can use the formula:

Area = |(x1y2 + x2y3 + x3y4 + x4y1) - (y1x2 + y2x3 + y3x4 + y4x1)| / 2

Given the vertices:

A = (0, 0)

B = (3, 6)

C = (8, 2)

D = (11, 8)

We can plug these coordinates into the formula to calculate the area:

Area = |(0*6 + 3*2 + 8*8 + 11*0) - (0*3 + 6*8 + 2*11 + 8*0)| / 2

Area = |(0 + 6 + 64 + 0) - (0 + 48 + 22 + 0)| / 2

Area = |70 - 70| / 2

Area = 0 / 2

Area = 0

The phi-coefficient is used when one variable is dichotomous and the other is regular, numerical scores. It is a measure of the association between two dichotomous variables, similar to Pearson’s correlation coefficient for continuous variables.

The phi-coefficient is an effective way to compare the difference between two variables because it compares the difference between the variables rather than the absolute values of the variables.

For instance, it is commonly used in psychology, social science, and other fields when the research focuses on categorical variables.

Answer:

The volume of the larger solid can't be determined with the information provided.

This is because you only know the volume and surface area of one solid, but you don't know the shape or dimensions of either solid. The volume and surface area are not enough to determine the shape, size or the volume of the larger solid.

In general, the relationship between the volume and the surface area of a solid is dependent on the shape of the solid. For example, a cube has a constant ratio of surface area to volume, while a sphere has a different ratio. So, knowing the surface area alone doesn't allow us to calculate the volume.

The standard form of a quadratic function is:

`f(x) = ax^2 + bx + c`

If the zeros of the function are 3 and 1/2, then the factors of the function are:

`(x - 3)` and `(x - 1/2)`

To find the quadratic function using these factors, you can first multiply them together:

`(x - 3)(x - 1/2) = x^2 - 7/2x + 3/2`

Now we have:

`f(x) = x^2 - 7/2x + 3/2`

This is the quadratic function in standard form that has zeros of 3 and 1/2.
