Let's look at an example:

2.24 x 21.6

2.24\\ 21.6\\ ______

Do normal multiplication and get

48384   This is not correct, until we put the decimals in. To know how to do this, count the number of decimal spaces from the factors. In 2.24, there are 2, because .24. In 21.6 there are 1 because of .6. This mean three places, so 48384 becomes

48.384

The rate of change is -5/4



I find it best to use the Slope formula
M= y2-y1/x2-x1



So we to use need any 2 points on the graph (I used the first 2)
•(0,200) and (80,100)

Now we set up the problem 100-200/80-0
Then you’ll subtract and should get
-100/80
Now you’ll simplify and once you’re done simplifying your answer should be -5/4.


Here is my work. Hope this Helps!

A regular hexagon is shown.
s2008m [1.1K]
Since the triangle will be a 30-60-90, because 360°/6 = 60° for each central angle, then that is bisected to find the height of each of the 6 equilateral triangles. This height is the same as the apothem.
In a 30-60-90 triangle, the sides are is the ratio of:
x \:  \\ x \sqrt{3} \\ and \: 2x
where x is opposite the 30° and 2x is opposite the 90°
Since the base is 10 and the hypotenuse is 10, 1/2 that is 5 (the x), and so:
x \sqrt{3}  = 5 \sqrt{3}  = 8.66
So rounded up, you apothem then is closest to D) 9 in.

A rectangle has sides with lengths (x+5) and (x+6) . Find the perimeter
Vika [28.1K]

Answer:

P = 4x + 22

Step-by-step explanation:

Formula

Perimeter = 2*L + 2*W

Givens

L = x + 6

W = x + 5

Solution

Perimeter = 2*(x + 6) + 2*(x + 5)     Remove the brackets on both terms

Perimeter = 2x + 12 + 2x + 10         Collect like terms

Perimeter = 4x + 22                       Answer
