2. Simplify 2(54−1)3
Romashka [77]

Answer:

3738

Step-by-step explanation:

use PEMDAS

Parentheses

Exponent

Multiplication

     or

Division

Addition

    or

Subtraction

one of those things above are not in the equation the skip it and for multiplication, division and addition, subtraction do not have to be done in order it is first come, first done for.  Example if there was a 1/2+3(4) you would do the division first

you always do the parentheses first

5 to the 4 power is 625

then you are left with

2(625-1)3then do 625 -1 is 624

and because of first come, first served and the 2 is first multiply the 2 to 624

you get 1246

then you have (1246)3

now you do 1246 multiplied by 3 and get your final answer

Hope this helps

Evelyn can run 5 laps around the track in 11 minutes. If she runs for an hour, how many laps will she run?
iris [78.8K]

Answer:

27 laps

Step-by-step explanation:

So first step is to work out how many times 11 fits into 60

\frac{60}{11}  = 5.4545455

Then you would times that by the number of laps which is 5

5.454545455 \times 5 = 27.27.....

So it is 27 laps as .27 of a lap is not a complete lap
