Which ratio is different from the other three 2/5 610 8/20 12:30

1 answer:

4 0

When we make decimals of all the fractions, we would get the following:

$\frac{2}{5} = 0.4$
$\frac{6}{10} = 0.6$
$\frac{8}{20} = 0.4$
$\frac{12}{30} = 0.4$

As you can see, all the numbers equal 0.4, with the exception of 6/10. Hence, the number with the other ratio is 6/10.

Answer:

Step-by-step explanation:

Think of of this as a function in which the number of pounds is a function of the number of hours. Each piece of given information is a point. Each point has the format (x, y) = (hours, pounds), where hours is x and is the independent variable, and pounds is y and is the dependent variable.

You have two points (4.5, 1445) and (7, 2320). First find the slope of the line that passes through those two points. Use the slope formula,

m = (y2 - y1)/(x2 - x1).

Then using the slope and the point-slope equation of a line, find the equation of the line. The point-slope equation of a line is

y - y1 = m(x - x1),

where m = slope, and the point is (x1, y1).

Try it. If you have questions or need extra help, just comment.
