Let x be the amount of nickels and y be the amount of quarters in a jar. Totally there are 87 coins, then x+y=87.
Since nickel is 5 cent coin and quarter is 25 cent coin, then 5x+25y=1255 ($12.55=1255 cents). Solve this system:x=87-y and 5(87-y)+25y=1255.
435-5y+25y=1255,
25y-5y=1255-435,
20y=820,
y=820÷20,
y=41,
x=87-41=46.
Answer: 46 nickels and 41 quarters.

Step-by-step explanation:
The formula for the area of a triangle is: 0.5*b*h (b = base h = height). The hypotenuse will be the longest side so we can rule out the number 60. Then you're going to multiply.
0.5*11*8 = 44
