Obill customers for water usage, one city converts the number of gallons used into units. this relationship is represented by the equation g = 748u, where g is the total number of gallons of water used and u is the number of units. determine which statements about the relationship are true. check all that apply. g is the dependent variable. u is the dependent variable. g is the independent variable. u is the independent variable. the two variables cannot be labeled as independent or dependent without a table of values. the two variables cannot be labeled as independent or dependent since any value can be selected for either.

g is the dependent variable; and u is the independent variable.

Step-by-step explanation:

We are given equation , where g is the total number of gallons of water used and u is the number of units.

Now, the number of units of water does not depend on the total number of gallons of water used. Now u is the variable that causes g to change.

So, u is an independent variable.

But the total number of gallons depends on the number of units used. As when more gallons are used, more units will be generated.

Therefore, g is a dependent variable.

answer set (b) 0.5, 3/4 80% is in order from least to greatest.  

step-by-step explanation:

in order to compare rational numbers to each other, it is much easier if they are in the same form.   typically, the best form in which to evaluate rational numbers is in decimals.   in order to convert a percent to a decimal, you would divide the given percentage by 100.   you can also accomplish the conversion by moving the decimal point over two places to the left.   for example, the decimal value of 80% is 80/100, or 0.8.   in order to convert a fraction to a decimal, you need to divide the numerator by the denominator.   for example, 3/4 is 0.75.   so, for choice (b) 0.5 3/4 (0.75), 80% (0.8) is the only choice in which the numbers are in order from least to greatest.
