A box of 14 cookies costs $8. What is the cost of 1 cookie?

Answers

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

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.

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

Answer: 1,000 x 20,000 = 20,000,000

1,200 x 15,000 = 18,000,000

20,000,000 - 18,000,000 = 2,000,000

First u need to find what percentage each person get in commission.
$1000 divided by $20000 is 0.05 which is 5%

$1200 divided by $15000 is 0.08 which is 8%
So julissa has a commission rate of 5% and destiny has a commission rate of 8%
So the difference is 3%

geometry I need help

Answers

Answer:

145

Step-by-step explanation:

Angle 4 and 5 are the same.

Which means that angle 3 and 6 are the same.

A straight line has an angle of 180 degrees in total.

This means that we have to subtract 35 from 180.

This gives us 145.

So, the missing angle is going to be 145 degrees.

*also, 1, 4, 5, and 8 are the same angle.

**2, 3, 6, 7 are also the same angle.

***I just remember learning about this last year, don't remember what there called tho.

Answer:145

Step-by-step explanation:

look at angle 4 and do 180-35 which is 145 and it has the same degree with angle 6
