Answer:
b = 60
Step-by-step explanation:
Using Pythagoras' identity in the right triangle
The square on the hypotenuse is equal to the sum of the squares on the other 2 sides, that is
b² + 63² = 87²
b² + 3969 = 7569 ( subtract 3969 from both sides )
b² = 3600 ( take the square root of both sides )
b = 
= 60

Answer:
D. 61 mi/h
Step-by-step explanation:
The travel time is 16:52 -8:13 = 8:39 hours, or 8.65 hours. Then the speed is ...
speed = distance/time = 527.65 mi/(8.65 h) = 61 mi/h

<em>Additional comment</em>
It is often convenient to use "military" or "24-hour" time for calculations of time periods that extend over noon or midnight. For this purpose, 12 gets added to the hour number in the afternoon (pm). Of course, 39 minutes is 39/60 hours. That is found to be 0.65 hours by performing the division of 39 by 60.
Well if you make 3/4 and 1/16 similar fractions by making 3/4 into 12/16 you get the answer in the numerator which is 12 tbsp of butter
3 chicken sandwiches at $2.75 each: 3*2.75= 8.25
2 cokes at 1.19: 2*1.19= 2.38
Tax: 0.64
8.25+2.38+0.64= 11.27
He gives you 11.52, to find how much you need to give him back, subtract how much he gives you by the amount that is charged (11.27)
11.52-11.27= $0.25
