Aperson has 22 coins, all nickels and dimes, worth one dollar and 50 cents. how many nickels are there?

8
14
22

14

Step-by-step explanation:

14 nickels is $0.70, and since the collective total is $1.50 there is $0.80 left, which is 8 dimes. 14 + 8 = 22, so the amount of coins is correct.

the highest percentage for deaths in construction from highest to lowest is as follows: falls, struck by objects, electrocution, and caught-in/between. these four are collectively known as fatal four.

in the case of falls, the type that is responsible for the overall highest death in the category is falls from roofs.
