Answer:

option B

Step-by-step explanation:

Given : A parallelogram ABCD

To find : Which graph shows a method for finding the image of point D if the parallelogram is reflected across the dashed line?

Since forming the reflected image follows Every point on the image will be the same distance as its corresponding point from the pre-image.

This distance will be perpendicular to the line of reflection i.e. dashed line

And the second option shows the correct image .

In the second image the perpendicular was draw along the axis of reflection .

Hence the option B is correct .

The second image shows a method for reflecting through this line.

Every point on the image will be the same distance as its corresponding point from the pre-image. This distance will be perpendicular to the line of reflection. The second image shows this process.

The ratio of people to books in a classroom is 10:4 what is the unit rate of people per book

Alex73 [517]

Answer:

Unit rate of people per book = 2.5

Step by step explanation:

Given:

Number of peoples = $10$

Number of books = $4$

Their ratios = $10 : 4$

We have to find the unit rate of people per book.

To find out the unit rate of people per book we have to divide the total number of peoples by the total number of books.

Or

For this we will follow the unitary method:

For $4$ book there are $10$ persons.

For $1$ book there will be $\frac{10}{4}$ persons.

So,

The numeric value = $\frac{10}{4}$

= $2.5$

There are 2.5 people per book and that it also the unit rate of people per book.

Two bottles and their labels are mathematically similar.

Trava [24]

Answer:

The area of the larger label is 187.5 square centimeters.

Step-by-step explanation:

If the two bottles are mathematically similar, then the label area is directly proportional to the capacity of the bottle. If we know that a 0.512 L-bottle has a label area of 96 square centimeters, then the label area of a 1-L bottle is determined by this simple rule of three:

$x = 96\,cm^{2}\times \frac{1\,L}{0.512\,L}$

$x = 187.5\,cm^{2}$

The area of the larger label is 187.5 square centimeters.

Vitek1552 [10]

Answer:

Step-by-step explanation:

51,200 divided by 52. (52 weeks in a year.) 984.615385 is answer. So each week he gets paid $984.62. So then we multiply that by 3 since we are finding 40% of 3 weeks of pay. $984.62x3= $2953.86. Then we multiply that by 40%.. $2953.86x40%= Answer is $11181.54

sphere and a cylinder have the same radius and height. The volume of the cylinder is 54 meters cubed. Amie found the volume of t

Fiesta28 [93]

Answer:

Amie should have multiplied 54 by 2/3

Step-by-step explanation:

The formula of the volume of a sphere is given by

$\frac{4}{3}\pi r^3$ , where r is the radius of the sphere.

to find the volume of the sphere, we must find $r^3$

We know that the formula of a cylinder of height h and radius r is given by

$\pi r^2h$

So $54 = \pi r^2 h$

We know that the sphere and the cylinder have the same height. Recall that the height of the sphere of radius r, is the diameter of a circle that passes through the heighest and lowest points of the sphere. Then, h=2r. This means that

$54 = 2\pi r^3$

From here, we know that $\pi r^3 = \frac{54}{2}$ .

So the volume of the sphere is $\frac{4}{3}\frac{54}{2} = \frac{2}{3}\cdot54$ .

So Amie should have multiplied 54 by 2/3.
