I drove to visit my Mom over Spring Break. She lives exactly 352 miles away (according to GoogleMaps). If my average speed was 55 miles per hour, how long did it take me to get to her house?

6.4 hrs(6hrs 24 minutes)

Step-by-step explanation:

-Speed is defined as displacement over time.

-Given speed=55mph and the displacement is 352 miles, the time can be calculated as:

Hence, it took 6.4 hrs(6hrs 24 minutes) to get to her house.

∠cbe and ∠deb are same-side interior angles.

i took the test

55.44 inches

step-by-step explanation:

part a. assuming a perfectly linear relationship, we can find the slope from the first two data points.

slope = m = (change in rainfall)/(change in years)

= (61.80 -62.33)/(2005 -2004) = -0.53/1 = -0.53

then the point-slope form of the equation of the line can be written as

y = m(x -h) +k . . . . . m = -0.53, (h, k) = (0, 62.33)

y = -0.53x +62.33 . . . x = years after 2004

part b. in 2017, x = 2017 -2004 = 13. then the predicted rainfall is

y = -0.53·13 +62.33 = 55.44 . . inches

the predicted rainfall in 2017 is 55.44 in.
