The answer is $1.75, im pretty sure

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

Midland Electronics is advertising that everything in their store is 10% off. If p represents the original price of an item in their store, then the sale price of the item can be represented by the expression

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.

Use a net of the square pyramid, if necessary, to find the surface area of the pyramid.

Answers

Imma guess 9 I’m not sure

Answer:

27 units squared

Step-by-step explanation:

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.

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.
