A satellite is composed of 30 modular units, each of which is equipped with a set of sensors, some of which have been upgraded.
Marta_Voda [28]

Answer:

\dfrac{1}{7}

is the fraction of sensors upgraded per unit.

Step-by-step explanation:

We are given the following in the question:

Let x be the number of upgraded sensors in one unit and y be the number of non-upgraded sensors in one unit.

Number of modular units = 30

Since some part of unit is upgraded and some are non-upgraded, then, we can write the equation:

x + y = 1

Number of non-upgraded sensors =

\dfrac{1}{5}\times \text{Total number of upgraded sensors on the entire satellite}

Thus, we can write the equation:

y = \dfrac{30x}{5}\\\\y = 6x\\1-x = 6x\\\\x = \dfrac{1}{7}

Fraction of sensors upgraded per unit =

\dfrac{1}{7}
