Answer:
There are 102 coins total:
34 Quarters
20 loonies
48 toonies
Step-by-step explanation:
Assuming money is counted in coins instead of value, it can be solved like this.
1. find a common denominator for 1/3 and 1/5. We can use 15. So, of the money collected, 5/15 were quarters and 3/15 were loonies. This makes 7/15 toonies. If there are 48 toonies, we can divide this by 7 to find the value of 1/15. 48/7 = 6 6/7. Multiply this number by 15 (for each value) and you get 102 6/7.

48 toonies

Answer:
height = 70 cm
Step-by-step explanation:
the area (A) of a triangle is calculated as
A = bh ( b is the base and h the height )
given b = 35 and A = 1225 , then
1225 = × 35 × h
1225 = 17.5h ( divide both sides by 17.5 )
= h , that is
70 = h
then the height of the triangle is 70 cm
