The answer is C 70 degrees
Answer:
25 1/2 square meters remaining
Step-by-step explanation:
Total area of the pool deck=76 1/2 square meters
He painted 2/3 of the deck before stopping for lunch
Total painted=2/3 of 76 1/2
=2/3*153/2
=306/6
=51 square meters
Total remaining=Total area - total painted area
=76 1/2 - 51
=153/2 - 51
=153-102/2
=51/2
=25 1/2 square meters remaining
Are they all on the same straight road?
If they are and the library is between his house and the school then the distance from the library to the school is 4/5 - 3/8 = 32/40 - 15/40 = 17/40 miles.
If they are on the same road but in opposite directions from his house then the distance is 3/8 + 4/5 = 32/40 + 15/40 = 47/40 miles.
If they are not on the same straight road then we cannot work out the distance exactly but it must be between 17/40 and 47/40 miles as these are the best and worst case examples.
