You can complete 40 pushups in 2 minutes. Your friend can complete 57 pushups in 3 minutes. Do these rates form a proportion? Explain

Answers

Answer 1

Answer:

No.

Step-by-step explanation:

In order to find the answer, you have to make the rates as simple as they get: In other words, you have to make it so that the rate has one on each side. Like this:

40:2

20:1

57:3

19:1

As you can see, they don't have the same numbers once their simplified. Which means that they can't be proportional. So, In this specific problem, you can do one more pushup in one minute than your friend can do.

Have a good day and good luck!

Answer:

552cm squared

Step-by-step explanation:

The first step is to find one of the surface areas of the triangles.

(12*17*0.5)

102

Now that we have one of them, we need to find what the four of them together is equal to.

(102*4) or 102 + 102 + 102 + 102

408

The next time is to find what the square is equal to.

(12*12)

144

The last step is to add the four triangles and the squares surface areas together.

408+144

552

The surface area of the shape is going to be 552cm^2

A. Small dogs weigh more than housecats.

B. The weights of small dogs are more consistent than the weight of housecats.

C. The housecats' weights have a higher mean and are more consistently centered around their mean.

D. The small dogs' weights have a higher mean and are more consistently centered around their mean.

Answers

Answer: C. The housecats' weights have a higher mean and are more consistently centered around their mean.

Step-by-step explanation:

if we were being more technical then he would be correct because the house cats have a higher mean than the smaller dogs.

SD= 9.9

HC= 11

so the house cats have a higher mean than the smaller cats, in addition has a more consistent mean then smaller dogs due to the range of the lowest in the highest number.

Answer:

C. The housecats' weights have a higher mean and are more consistently centered around their mean.

Find the scale factor for the dilation shown.

Answers

The scale factor is 4.

First you need to find the length and height of the squares.

Bigger square:
Length = 20
Height = 16

Small square:
Length = 5
Height = 4

Then take the heights and lengths and divide the bigger numbers (lengths in this case) by the smaller numbers (heights in this case)
*This is using inverse operations. Diving to get what to multiply, since scale factor is multiplying.

bigger shape LENGTH divided by smaller shape LENGTH:
20 units / 5 units = 4

bigger shape HEIGHT divided by smaller shape HEIGHT:
16 units / 4 units = 4

There’s your answer!

Also you didn’t really have to do lengths AND heights, only one, because you already knew both shapes were similar.

if you didn’t know:
the “/ “ symbol means divide






scale factor is 4 since 16/4 is 4

RUST is the name of this quadrilateral because the points on the shape are named “R”, “U”, “S”, and “T”. But that doesn’t totally matter.

R(1, 5) *this is the R point we’re looking at

Translation:
So you just +1 to the x-value, (1 in this case) and your x-value is 2.

Then you -2 from the y-value, (5 in this case) and your y-value is 3.

So your R’ point is now at (2, 3) on the coordinate grid.


Dilation:
They said you dilate the shape by 3, but you just have to figure out R.

So literally all you do is multiply both the x and y values by 3.

Scale Factor 3 * (2, 3)

(2 * 3, 3 * 3)
multiply 2 by the scale factor, 3
then same with the y value 3

Then you’d get (6, 9), that’s the R” point!


if you didn’t know:

* means multiply

‘ after a points’ name is the new point after one transformation. The more ‘ you put after a letter, the more times it’s been transformed.
in this case, R’ was after translations. And R” was after a translation AND dilation.

Answer:

A cookie costs $4/7

Step-by-step explanation:

Let's write an eqution in which X represents the cost of a cookie

14x=8

Now divide both sides by 14

[tex]x=\frac{8}{14}[/tex]

Now simplify by 2

[tex]x=\frac{4}{7}[/tex]

So a cookie costs $4/7

First, we find the surface area of one of the triangles.

(3*3*0.5)

4.5

Next, we find the surface area of all of the triangles.

(4.5*4)

18

The next step is to find the surface area of the square.

(3*3)

9

The last step is to add the surface areas of the square and triangles together.

(18+9)

27

The surface area of the entire shape is going to be 27 units squared.
