X is equal to 440
440/8=55
Answer:

Step-by-step explanation:
The satellite has 30 modular units.
There are equal numbers of non-upgraded sensors in each unit.
Let us assume that on the entire satellite there are x numbers of upgraded sensors.
Then as per the given condition, there are
number of non-upgraded sensors in one unit.
Therefore, the number of non-upgraded sensors on the entire satellite is
=6x
Hence, total number of sensors in the satellite is (x+ 6x) =7x
Therefore, the required fraction of the upgraded sensors is
. (Answer)
Answer:
3 km
Step-by-step explanation:
<em>(NOTE: One kilometer is 1000 meters)</em>
Divide 3000 by 1000 to get 3
