the price of an antibiotic in one drugstore is $19.50 and $16.25 in another write the ratio of the prices

1 answer:

8 0

Remember that ratios are essentially fractions without fraction bars...

If they asked to find the ration of 19.50 to 16.25 you would set them up like so....

19.50 : 16.25 -----> since fractions can be simplified so can ratios in the same manner

the ratio you would end up with is 6 : 5

Ratios can be easily remembered and solved if you understand the link between them and fractions.

I hope this helps! :D

Which statements about the graph of the function y=(1/3)

Elena-2011 [213]

Answer: The range of the function is all real numbers is true.

Explanation: the graph of y = 1/3 is just a horizontal line at y = 1/3. so it’s not increasing or decreasing (it’s staying the same). there is no x-intercept, and the y-intercept is (0, 1/3). the range is all the possible y values, and there are infinite possible y values, so it is all real numbers.
