0.6, the tenth place is the one after the decimal point (or what ever you call it) and to round it you look at the number behind it. If it is smaller than 5 you don't round it, but if it is bigger you round it up.

Answer:

$\frac{5}{6}$ inches per week

Step-by-step explanation:

This is a very simple ratio problem. Basically,

<em>If $1\frac{1}{4}$ inches in $1\frac{1}{2}$ week, then HOW MANY INCHES (let it be x) in 1 week???</em>

<em />

We set up two ratios and cross multiply and solve for x:

$\frac{1\frac{1}{4}}{1\frac{1}{2}}=\frac{x}{1}\\1\frac{1}{4}*1=1\frac{1}{2}*x\\1\frac{1}{4}=1\frac{1}{2}x\\x=\frac{1\frac{1}{4}}{1\frac{1}{2}}\\x=\frac{\frac{5}{4}}{\frac{3}{2}}\\x=\frac{5}{4}*\frac{2}{3}\\x=\frac{5}{6}$

So average rate at which the water level changed every week is 5/6 inches per week.

The price of dress fabric is proportional to the length of fabric purchased. The graph shows this relationship.

C. 8$/m. The rate is the same as the slope. To find the slope, we find "rise over run," or the change in the height/change in length (OR, change y/ change x)
The change in y is 24-8=16
The change in x is 3-1=2

16/2= 8$/1 m. This is the unit rate because it describes the change in y over ONE UNIT of x.
