- 5 + -3 = -8

when a negative number adds a negative number, it will be negative
when a negative number adds a positive number, whichever number (either positive or negative) take the sign of the bigger one
For example:
-4 + 3 = -1
-5 + 10 = 5

The mean is the average of the numbers, so if x = all 11 numbers added together, then you have the equation:
x / 11 = 7, so x = 77 (this is all of the numbers added together)
if the number 13 is removed, the equation becomes:
(77 - 13) / 10 = M (M is the new mean)
so the new mean is 6.4
The volume of a cone is V=(1/3)•pi•r^2•h
now you plug in your given values
V=(1/3)•pi•2^2•5
the final answer is (20/3)pi
<h3>
Answer: Point D</h3>
Explanation:
The origin is the center of the grid. This is where the x and y axis meet. The location of this point is (0,0).
Start at the origin and move 5 places to the right. Note how the x coordinate is 5 which tells us how to move left/right. Positive x values mean we go right.
Then we go down 2 spots to arrive at point D. We move down because the y coordinate is negative.
You could also start at (0,0) and go down 2 first, then to the right 5 to also arrive at point D. Convention usually has x going first as (x,y) has x listed first.
The mirror cost when the cpi is 211, to the nearest cent is $187.69
<h3>Ratio and proportion</h3>
Fraction is expressed as a ratio of two integers. For instance a//b is a fraction where a and b are integers.
From the given question, a full-length mirror cost $144.99 when the cpi was 163, hence;
$144.99 = 163 cpi
In order to determine the mirror cost when the cpi is 211, we will write;
x = 211 cpi
Find the ratio;
144.99/x = 163/211
163x = 30592.89
x = 30592.89/163
x = 187.69
Hence the mirror cost when the cpi is 211, to the nearest cent is $187.69
