Answer:

Step-by-step explanation:

The perimeter is the length of the outline of a shape. To find the perimeter of a rectangle, square or other you have to add the lengths of all the sides.

For example if it comes out to 90 then you round it to the nearest hundredth.

Hope it helps

It takes 18 hours to fill a pool using 8 garden hoses. How long would it take to fill the same pool using 9 garden hoses?
levacccp [35]
Use rates, so 8 garden hoses over 18 hours
then find the how many hours one garden house can fill up by doing this = 18/8 you divide the 8 for both sides which is about 2.25/1
so then you times 9 which is about 20/9 hoses
your answer is 20

It's just a simple equation but the transversal has me stuck
alexgriva [62]

Answer:

x = 22

Step-by-step explanation:

∠VSR and ∠SRU are same- side interior angles and are supplementary, thus

5x + 4 + 44 + x = 180, that is

6x + 48 = 180 ( subtract 48 from both sides )

6x = 132 ( divide both sides by 6 )

x = 22

Compare a dilation to the other transformations: translation, reflection, rotation.
inysia [295]

Answer:

We know that there are four types of rigid transformations namely Dilation, Translation, Reflection and Rotation.

Now, Dilation is the transformation that changes the size of the figure by some scale factor i.e. it is the transformation that increases or decreases the size of the given figure.

We can see in the first figure that the triangle ABC is dilated ( increased by some scale factor ) to form A'B'C'.

Further, Translation is the transformation that slides the figure horizontally or vertically to a fixed distance.

The second figure shows the change of position of the solid ABCD to the position of A'B'C'D'.

Now, Reflection is the transformation that flips the image about a straight line.

During reflection, the size of the figure remains same but the it goes to the opposite side of the line.

We can see from the third figure the reflection of ABC about the y-axis to form A'B'C'.

Finally, Rotation is the transformation that turns the image about a fixed point called the center of rotation to a certain degree.

So, in the last figure, we see that the image A is rotated about the center of rotation by 120° to form A'.

Hence, we see that Dilation is different from the other transformations.

Wilbur sold half of his comic books and then bought fourteen more. he now has 24. how many did he begin with?
rosijanka [135]
First, subtract 24 - 14 to get how many books he had after he sold half of his collection and bought 14 more:

24 - 14 = 10

10 = number of books after he sold half of his collection.

Now, you need to multiply 10 x 2, because you need to find the original number of comic books:

10 x 2 = 20

He originally had 20 comic books.

An equation you could use for this question is:

2(24 - 14) = x. (X = number of comic books)

Hope this helps!!
