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:
There are 106 dimes
Since, n = 183 - d
n = 183 - 106
n = 77
There are 77 nickels
The wheel turned a total of 300 times in 1,884 feet.
Step-by-step explanation:
Step 1:
The wheels of the bicycle have a diameter of 24 inches. So the radius of the wheels is 12 inches.
To determine how many times the wheel turns we divide the distance traveled by the circumference of the wheels.
The circumference of a circle is given by multiplying 2π with the radius.
The circumference of the wheel
The circumference of the wheel is 75.396 inches.
Step 2:
Gia traveled 1,884 feet, we need to convert this into inches.
If 1 feet = 12 inches, 1,884 feet = 22,608 inches.
The number of times the wheel turned
Rounding this off, we get that the wheel turned a total of 300 times in 1,884 feet.
