Answer:

Step-by-step explanation:

He took a rest from driving at 4pm. That is proved through there being no change in the number of miles from 4pm to 5pm.

He covered 50 miles from 1pm-2pm and 3pm-4pm. 175-125=50 and 250-200=50.

I am not sure about the answer to part c but it is not iii, so it is either i or ii.

I also do not believe it is i because you can calculate his speed from the given information on the graph so if I were you I would circle ii.

I’m confused on this one
dedylja [7]

It's a parallelogram so if one angle is 90 degrees they all will be because of transverse angles and all that good stuff.


So we're given the diagonal of a rectangle and one side and we're asked to find the other. The diagonal of a rectangle is the hypotenuse of the right triangle whose legs are the sides of the rectangle. So this is a Pythagorean Theorem question in disguise:


AB^2 + AD^2 = BD^2


AD^2 = BD^2 - AB^2


AD = \sqrt{ BD^2 - AB^2 }


AD = \sqrt{149^2 - 51^2} = \sqrt{19400} = 140


Answer: 140 cm


I don't recall seeing this Pythagorean Triple before.
