Rom4ik [11]

Answer:

3/4 or .75

Step-by-step explanation:

The mean means the average so you would add up all the numbers then divide by how many numbers there are

-3+4+8+-1+-4+-2+0+2+5+2+-3+1= 9

9/12= 3/4 or .75

depends whether or not you want it in fraction or decimal form

What is the area of a square with a side of 8x^7 y^3
sukhopar [10]
Area of a square with side s is \sf{s^2}

In your question, the side or s is: \sf{8x^7y^3}

And so the area of a square with that side length would be:

\sf{(8x^7y^3)^2}

And using this formula: \sf{(a^b)^c =a^{b\times c}}

We get that the area is:

\sf{(8x^7y^3)^2 = 8^2 x^{7\times 2} y^{3\times 2}}

And simplifying that we get the final answer as:

\huge{\boxed{\bf{Area=64x^{14}y^{6}}}}

Please HELP me 50 points worth
Leokris [45]

Answer:

y=-½x + 1

Step-by-step explanation:

1.) a perpendicular lines uses the opposite inverse of a line so the slope becomes -½x

2.) make an equation that looks as so:

y=-½x+b

the y intercept is unknown so it must be a variable.

3.) substitute the points you are given into the equation:

3=-½(4)+b

4.) solve for b

3=2+b

-2|-2

1=b

4.) place b into the equation

y=-½x + 1

An animal shelter houses only cats and dogs, there are 25% more cats these dogs. If there are 40 cats, how many dogs are there,
jok3333 [9.3K]

Answer:

There are 32 dogs and 72 animals in total.  

Step-by-step explanation:

In order to find the amount of dogs, you need to set up an equation to solve for the missing variable.  Let 'c' be the amount of cats and 'd' be the amount of dogs.  We know that there are 40 cats, so c = 40.  We also know that there are 25% more cats than dogs, so we can form an equation to express this difference:  1.25d = c, indicating that the number of cats is equal to the total number of dogs, plus an additional 25%.  Since we know c = 40, we can set our second equation equal to 40:  1.25d = 40.  Using inverse operations, we divide both sides by 1.25 to get d = 32.  So, d + c, or 32 + 40 = 72 total animals.
