The scale of his model to the actual car is 1:10 is model is 16 1/2 inches long how long is the actual car

165 inches, or 13 feet and 9 inches

Step-by-step explanation:

Because the ratio of the model to the actual car is 1:10, you know that the actual car is ten times bigger than the model. You can multiply the length of the model by ten to get the length of the actual car with this information.

16.5 x 10 = 165 inches

If you're being asked to convert to feet, do so by dividing by twelve and taking the remainder as your remaining inches.

165 / 12 = 13 r 9, meaning 13 feet and 9 inches

Let me know if you need more of an explanation for anything!

since your problem is x^4 = 81, what you have to undeo is the "to the fourth power" part.

the inverse (opposite operation) of "to the fourth power" is "to the fourth root".

  (x^4) ^ ¼   = 81 ^ ¼  

  81 = 3^4     so (3 ^ 4) ^ ¼   =   3 ^ 1   = 3

by hand: (3 ^ 4) ^ ¼   =   3 ^ (4 x ¼) = 3 ^ 1   = 3   (when you take a power to a power, multiply the exponents.)

or, do it by calculator. one way of finding the fourth root is to use ^ (1/4)

3/6 chance

step-by-step explanation:

half of the nubers are odd numbers (1,3,5) which in that case if you would be told to simplify it would be 1/2
