Answer:
Explanation:
Let x be the age of the person who enter the room
(18 + 25 + 18 + 21 + 16 + x)/6 = 25
(77 + x)/6 = 25
77 + x = 25(6)
77 + x = 150
x = 150 - 77
x = 73
If the Earth were a flat surface, then 9 miles east and 12 miles north would be
the basis of a right triangle, and the straight-line route would be the hypotenuse.
We could use the Pythagorean Theorem to find the straight-line distance.
A² + B² = C²
C² = (9)² + (12)²
C² = 81 + 144
C² = 225
C = √225 = <u>15 miles</u>
That's Choice-'H'.
Answer:

Step-by-step explanation:
If he had 50 chocolates and give 3 to each friend them you find the closest number to 50 that 3 can go into. The biggest number that 3 can go into is 16. 3 times 16 is 48. And with 48 there is still 2 left over.
