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:
72

For this item, I assume that Svetlana's hair is 4 cm long and she wanted it to be at least 7 cm long.
We let x be the number of months it will take for her hair to be 7 cm long. The sum of the product of x and the rate and the initial length should be at least 7. Mathematically,
1.51x + 4 ≤ 7
