3.3x10^-3 in standard notation
const2013 [10]
First you do the exponents so 10^-3 is:

1/10^3 (change it so it is not a negative exponent, so make it its reciprocal)

1/(10*10*10) = 1/1000 = 0.001

Jerry multiplied 3.04 x 7.091 and got the product 2.155664. Is his answer reasonable? Why or why not?
Readme [11.4K]

First we multiply the numbers ignoring the decimal and then place the decimal in the position

3.04 *7.091 = 2155664

Now the first number has two digits after the decimal and the second number has three digits after the decimal.

Therefore in the final result we have to move the decimal (2+3) =5 place from the left,

So the answer would be 21.55664

So, the correct answer is 21.55664

Jerry calculated the answer correctly , but made an error in the placement of the decimal point.  The answer is not reasonable because 2.155664 and 21.55664 mean two completely different answer far apart from each other

grandymaker [24]

we are given

A woman walks due east on the deck of a ship at 4 mi/h.

the ship is moving south at a speed of 24 mi/h

so, firstly, we will draw diagram

so, we have

OW=4

OS=24

now, we can use Pythagoras theorem

SW^2=OS^2+OW^2

now, we can plug values

and we get

SW^2=24^2+4^2

SW=24.33

so,

the speed of the woman relative to the surface of the water is 24.33 mi/h .......Answer
