Convert the following numbers to Mayan notation. Show your calculations used to get your answers. 135?
Step2247 [10]

Answer:

The answer to your question is below

Step-by-step explanation:

In Mayan notation there are only 3 symbols

   dot   .    means one

   line   ---   means five

  snail          means zero

And the are three levels,     the lower means     x 1

                                              the first means       x 20

                                              the second means  x 400

                                              the higher means    x 8000

Then, 135 is lower than 400, so we must start in the first level and need to divide 135 by 20.                         6

                                        20    135

                                                   15

Finally place 6 in the fist level and 15 in the lower lever, like this

And 120 + 15 = 135.

If three candys cost four dollars how much would two candy cost?
IrinaK [193]

Answer:≈2.67

Step-by-step explanation:

To figure this problem out, we must first figure out what a single piece of candy costs. So we take the total cost of the three candies and divide that number by the number of candies, or:

4/3,

to give us the number 1.3 repeating. This means that a piece of candy would cost $1.33. We multiply this by two to get approx. 2.67, or $2.67.

Hope that helped.
