A model car is 5 inches long. The actual length of the car is 15 feet . What is the scale factor of the model car?

Elodia [21]

Answer:

1 : 36

Step-by-step explanation:

To obtain the scale factor, the dimensions must be in the same units.

Using the conversion

1 foot = 12 inches, then

15 feet = 15 × 12 = 180 inches, thus

scale factor = 5 : 180 ← divide both parts by 5

scale factor = 1 : 36

Which equation can be used to solve the following word problem? Seth has 8 more nickels than dimes, and the total value of his c

9966 [12]

Answer:

Seth has 21 nickels

Step-by-step explanation:

Let n represent the number of nickels. Since Seth has 8 more nickels than dimes, then (n-8) is the number dimes.

Nickel is worth 5 cents and dime is worth 10 cents. Thus, n nickels are worth 5n cents and (n-8) dimes are worth 10(n-8) cents. The total value of Seth's coins is $2.35 that is 235 cents, then

$5n+10(n-8)=235.$

Solve this equation:

$5n+10n-80=235,\\ \\15n=235+80,\\ \\15n=315,\\ \\n=21.$
