How many digits will follow the decimal point when you multiply 3.68 x 42.7

You can tell how many decimal places will be in the answer by looking at how many decimal places there are in the question.

For example:    3.68 has  2 decimal places, and 42.7 has 1 decimal place,  so when you multiply 3.68 by 42.7, there will be 3 decimal places ( 2 + 1 = 3)

Another example:  The answer to 2.76 x 13.091 will have 5 decimal places in it - because 2.76 has 2 decimal places, and 13.091 has 3 decimal places - 2 places + 3 places = 5 decimal places.

b) k’(6, 4); l’(3, 3)

step-by-step explanation:

a 270° clockwise rotation maps every point (x, y) to (y, -x). (it negates the x-coordinate and then switches it and the y-coordinate.)

this means the endpoints of the side congruent to kl, k' and l', would be mapped as:

k'(-4, 6)→(6, 4)

l'(-3, 3)→(3, 3)
