1) Which ratio is equivalent to [tex] \frac{4}{16} [tex]?
[tex] \frac{4}{16} * 2 = \frac{8}{32} [tex], or
8:32.
2) Write the ratio as a unit rate [tex] ( \frac{286miles}{5 \frac{1}{2} hours} ) [tex]
Set the equation up like this:
[tex] \frac{286miles}{5 \frac{1}{2} hours} = \frac{Xmiles}{1 hour}\\
286*1=(5 \frac{1}{2})*x\\
286 = \frac{11x}{2}\\
11x= 572 [tex]
x =
52 [tex] \frac{miles}{hour} [tex]
3) Which typing time is fastest? I answered this earlier, refer to it please refer to it:

The question is an illustration of equivalent equations.
<em>There are 11 units in all</em>
The given parameters are:
<u>Sage</u>



<u>Tristan</u>



Andre has twice of what Sage has
So, the total unit is:

<em>Sage has 2 units</em>
<em>Tristan has 5 units</em>
<em />
Because, Andre has twice of what <em>Sage has,</em>
Andre's number of units would be 4
So, we have:


Hence, there are 11 units in all

The answe The answer would be C
Answer:

Step-by-step explanation:
Slope can be represented as rise over run (change y-values over change in x-values). Since the y-value is changing by -2 every time the x-value is changing by 2, the slope of the line must be
.
In slope-intercept form
,
represents the slope of the line,
represents the y-intercept, and
represent the coordinates of any point the line passes through.
To find
, substitute
and any point the line passes through.
Using (1, 0) from the table:

Thus, the equation of this line is 
Given:
A number is

To find:
The scientific notation of the given number.
Solution:
Scientific notation of a number is the product of a number between 1 to 10 and 10 to the power some integer.
We have,

It can be written as



Therefore, the scientific notation of the given number is
