A car travels 106.2 miles in 2.3 hours
(with a constant speed). How much time
will it take traveling 385.2 miles?

Kawaii, the problem is the comparison with the calculated time for Jillian and the actual time for Jillian to run the 7 miles.

%error=(calculated value - experiemental value)/calculated * 100%

%error=(95-80)/95*100%=15/95 *100% = 15.79 ≈ 16% error

Note: 16% error is the approximate error because the numbers have 2 significant figures stated in the problem.

Step-by-step explanation:

i asked a expert on google

step-by-step explanation: h: (- 3, 6)

m: (1, - 2)

o: (7, 6)

r: (- 9, - 2)

midpoint of hm: (- 1, 2)

midpoint of or: (- 1, 2)

therefore, b is the midpoint of both diagonals bisect each other !

to prove the diagonals are perpendicular, show that the product of the slopes = - 1

step-by-step explanation:

this is not possible to solve with the info given.   you need at least an one angle somewhere.
