Answer:
The silver is now 50 years old and the gold coin is 18 years old
Step-by-step explanation:
first the silver was 32 years old , and it said it would be three times as old as the gold coin, to find the gold coin is to divide 32 and 3 together, that would be 10.6 but you can round the number up, you get 10 years.
you now can just get add 8 years to the 32 and 10
that would be 50 years old silver coin and 18 years for the gold coin.
Answer:
3 Minute
Step-by-step explanation:
So the pool can hold 60 gallons, and the pool already has 12 gallons. He wants to fill it up to 27 gallons, so the amount of gallons he has to fill is 27-12 = 15. if 6 gallons are poured in per minute and 6x2 = 12, 6x3 = 18, it will take 3 minutes for the pool to be filled
Answer:
No
Step-by-step explanation:
In a right angle triangle, based on Pythagoras theorem, the sum of the squares of the adjacent and opposite sides must equal to the square of the hypotenuse.
The hypotenuse is the side with the longest length:
H² = O² + A²
if from the given lengths;
H = 11, O = 9 and A = 6
Let us see if this is true;
H² = 9² + 6²
H² = 81 + 36
H² = 117
But H², 11² = 121 and this is not true
The triangle is not a right angled one.
