Answer:
Seb will take 13 minutes and 20 seconds to run 4000 m at an average speed of 5 m/s
Step-by-step explanation:
time taken = distance / speed
time taken = 4000/5
time taken = 800 seconds
time taken = 13 minutes and 20 seconds
- (2x+y+2z) = -(2(x+z) + y)
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>
Answer:
There are 5 black counters in the bag.
Step-by-step explanation:
15 green counters in the bag
The proportion of green counters is given by:
So, we have that, the total is x. So
There are 30 total counters.
How many black counters are in the bag ?
A sixth of the counters are black. So
There are 5 black counters in the bag.
The given triangle is a right angled triangle,
so let's apply trigonometry here :
