Answer:

0.4 second

Step-by-step explanation:

The formula D = st is the formula that can be used to substitute in the values (which is already in the problem).

If the speed is 175 meters a second and the distance is 70 meters, than that means 70 = 175t.

(I substituted 70 for distance, or D, and 175 for speed, or s).

Divide 175 on both sides in order to isolate the variable (t), which is 0.4 second.

The time taken for the hurricane to reach the shore would be 0.4 second.

Eric has 183 coins all of them are nickels and dimes. If the total value of the coins is 14.45, how many of each denomination co
FromTheMoon [43]

Answer:

77 nickels

106 dimes

Step-by-step explanation:

Let there be n nickes and d dimes

Since there are 183 coins, we can write:

n + d = 183

Also, the value of nickel is 0.05 and dime is 0.1, total value is 14.45, so we can write:

0.05n + 0.1d = 14.45

Solving 1st equation for n, we have:

n = 183 - d

Putting this into 2nd equation and solving for d:

0.05n + 0.1d = 14.45\\0.05(183-d) + 0.1d = 14.45\\9.15-0.05d+0.1d=14.45\\0.05d=5.3\\d=106

There are 106 dimes

Since, n = 183 - d

n = 183 - 106

n = 77

There are 77 nickels
