Acopper contact is insulated from its support with one piece of mica 1⁄64 inch thick, two pieces of fiber that are each 1⁄8 inch thick, and 1⁄16 inch of pressboard. the copper is 3⁄4 inch thick, and the support is 7⁄8 inch thick. what is the total thickness of copper, insulation, and support?

125/64=1(61/64) inch

Step-by-step explanation:

The complete thickness would be the sum of individual thickness in the array.

The cooper would be the upper layer with 3/4 inch thick, the support is the middle layer composed by three sublayers: 1/64 inch mica, 2 pieces of fiber of 1/8 inch each (2/4 inch both) and a pressboard with 1/16 inch thick. The bottom layer is the support with 7/8 inch thick.

The sum would be:

11 15 15/x

Jonah spent the cost of a movie ticket and split the cost of popcorn, so this needs to be represented by a " + ". Jonah just buy one piece tickets, so 11 is tickets price. We know Jonah's costs represented by the expression 11+15/x, "x" on behalf of the number of he and his friends, so 15 is the price of popcprn. 15/x means one person's money for the poopcorn, including Jonah.
