5 calculators cost $140.00

Answers

Answer 1
28$ each calculator

Explanation:

140 / 5 = 28
Answer 2

Answer:

The cost of 1 calculator is $28.00

Step-by-step explanation:

You haven't mentioned the question. Anyways if you want to find the value of 1 calculator, the simplest method ( in my opinion) you could do so in the ratio method:

 5 calculators : $140

 1 calculators : x

( x is the cost of 1 calculator. You have to find x. )  

Cross multiply both the ratios. Multiply 5 with x and 140 with 1.

5x = 140 × 1

5x = 140

Bring 5 to the other makes 140 divided upon 5, as it was multiplied with x.

x = [tex]\frac{140}{5}[/tex]

x = $28

You could not only find the cost of 1 calculator, but any number of calculators. Just replace the number of calculators with 1 calculator that I have found the cost of.

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.

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:

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

Geometry i need help, please EXPLAIN how you got iy

Answers

Answer:

start where r is at, then go down 2 units to then to the right 2 times

Step-by-step explanation:

not sure but worth a try

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.
