total distance travelled=72+69=141
time taken in hours for journey= (48/60)h + (69/60)= 1.95 h
average speed=141km/1.95h= 72.3km/h (3 sf)
Answer:
<em>2,300,000pages report.</em>
Step-by-step explanation:
Given a USB drive with memory of 4.6*10⁶KB, in order to know the maximum number of pages a report can have so that it can be completely stored on the drive, the conversion factor must be used.
We must first understand that 1 page of a document uses up approximately 2kB of the storage.
Since 2kB = 1page
4.6*10⁶KB = x page
Cross multiply
2kB * x = 4.6*10⁶KB * 1
2x = 4.6*10⁶
x = 4.6*10⁶/2
x = 2.3*10⁶
x = 2,300,000
<em>Hence the maximum number of pages that the report can have so that it can be completely stored on a USB drive that holds 4.6*10⁶KB is approximately 2,300,000pages report.</em>
Since this is subtraction, everything must be turned negative in the second polynomial.
(6x^2 - 5x) - (2x^2 + 3x - 2)
6x^2 - 5x - 2x^2 - 3x - (-2)
6x^2 - 5x - 2x^2 - 3x + 2
Now, reorder the terms to make it easier.
6x^2 - 2x^2 - 5x - 3x + 2
Now, just combine like terms.
4x^2 - 5x - 3x + 2
4x^2 - 8x + 2
There’s the answer!
