Answer:

Approximately 307 miles

Step-by-step explanation:

Since this is not exactly linear, but the data resemble a line, you will use the linear regression program on your calculator.  Go to "stat" then edit.  Enter the number of gallons in L1 and the number of miles in L2.  When you are done with that, hit "stat" again, arrow over to "calc" and go down to LinReg.  Hit enter and you will get the linear regression equation, which is the same thing as the line of best fit.  It is

y = 19.4x +16

We want to find the number of gallons, y, that you can go on x = 15 gallons of gas.  Sub in 15 for x and do the math:

y = 19.4(15) + 16 gives you

y = 307

Which dimensions can create more than one triangle?
garri49 [273]

Answer:

three sides measuring 4 ft, 8 ft, and 10 ft

Step-by-step explanation:

To choose which dimensions that can create more than one triangle, we consider the given values carefully and how possible it will be to construct.

The only dimensions given in the option that will be possible to create more than one triangle from it, is three sides measuring 4 ft, 8 ft, and 10 ft.

4 ft, 8 ft, and 10 ft are in simple multiple of 2

4 ft, 8 ft, and 10 ft  = 2 (2 ft, 4 ft, and 5 ft ), with this we can construct two triangles with three sides measuring 2 ft, 4 ft, and 5 ft.
