Using a very precise measuring device, dr. calvin measured the thickness of a piece of metal to be 0.00064 of a meter. dr. amos measured another piece to be 2.5 × 10-5 of a meter thick. if the doctors put the two pieces of metal on top of each other, the new piece of metal would be × 10-4 of a meter thick.

of a meter in scientific notation.

0.000665 meter in standard notation.

Step by step explanation:

We have been given that Dr. Calvin measured the thickness of a piece of metal to be 0.00064 of a meter. Dr. Amos measured another piece to be of a meter thick.

We can see that Dr. Amos has given measurements in scientific notation. Let us convert thickness measured by Dr. Amos from scientific notation to standard notation.

Now let us add both measurements to find the thickness of new metal piece.  

Now let us convert thickness of new piece of metal in scientific notation.

Therefore, the thickness of new piece of metal will be of a meter or 0.000665 meter.        

the naturalist literary movement was an extension of the realist literary movement, a movement that strove to portray life as it really was hope it

step-by-step explanation:

(2,20) means that the 2 is 2 hours and 20 is 20$. so there both 20$ for 2 hours only the same price. like it says. so, the dunk tank and the bounce house are the same price (20$) for the same amount of time (2 hours).
