Given a right triangle, find the measures of all the angles, in degrees, if one is a right triangle and the measure of the second angle is six less than seven times the measure of the third angle. (show work )

You can find the constant of proportionality by finding the ratio of

Create a data set with 8 points in it that has a mean of approximately 10 and a standard deviation of approximately 1.

Suppose that a households monthly water bill (in dollars) is a linear function of the amount of water the household uses (in hundreds of cubic feet, hcf). when graphed, the function gives a line with slope of 1.65. if the monthly cost for 13 hcf is $46.10 what is the monthly cost for 19 hcf?
