Helen determined she walks about 1,800 steps per 4/5 mile. How many steps did she take if she walked 3 miles?

olga_2 [115]

$1,800\ steps\ \ \rightarrow\ \ \frac{4}{5} \ mile\\ x\ \ \rightarrow\ \ 3\ miles\\ \\\frac{4}{5} \cdot x=1,800\cdot 3\ /\cdot\frac{5}{4} \\ \\x=1,800\cdot\frac{5}{4}\cdot3 \\ \\x=450\cdot15\\ \\x=6750\ [steps]$

Kelly has 4 dimes and some nickels. The value of her coins is 2.25 how many

Semmy [17]

4 dimes=4 *10=40 cents

2.25-0.40=1.85

1.85=0.05 times number of nickles
times 100 both sides
185=5 times number of nickels
divide both sides by 5
37=number of nickles

has 37 nickles

Whats 14.635 rounded to the nearest cent?

Nutka1998 [239]

The cents are .635 and the greatest cent is 6. So, when it is rounded to the greatest value like estimating it will be 14.600 or 14.6. As easy as that. :)
