Answer:

<em>height (h) = 15</em>

Step-by-step explanation:

To figure this out, we use the formula <em>2 · </em>\frac{A}{a + b}, where "A" is the area, "a" is one base measure, and "b" is the other base measure.

After plugging in the numbers into the formula, we get <em>2 · </em>\frac{390}{23 + 29}, which equals 15.

my dad is 40 miles away at work...if he leaves work at 6:24pm...and travels at an average of 43 miles per hour...what time is he
ExtremeBDS [4]
If his speed is 43 mph, then it takes him 40/43 of an hour to go 40 miles.

An hour = 60 minutes.

40/43 of 60 minutes = 55.8 minutes. He gets home 55.8 minutes after 6:24 PM.
