What is 14.36 rounded to the nearest tenth?
Vinil7 [7]
14.36 rounded to the nearest tenth is 14.4 (14.40). 

Why? 

Well because when rounding first we see what number we need to round. In this case it is 14.36 (3), next we look at the next number after the number which we need to round from which is 14..36 (6). If this number is 5 or MORE then we will round to the next number. But if it is LESS than 5 then we will keep it that number and add a 0 at the end. Since this number is AFTER 5 it will round up to 14.40. 

So, 14.36 rounded to the nearest tenth is 14.40.

Hope I helped ya!!!

A satellite is composed of 30 modular units, each of which is equipped with a set of sensors, some of which have been upgraded.
Anit [1.1K]

Answer:

\frac{1}{7}

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 \frac{x}{5} number of non-upgraded sensors in one unit.

Therefore, the number of non-upgraded sensors on the entire satellite is \frac{30x}{5} =6x

Hence, total number of sensors in the satellite is (x+ 6x) =7x

Therefore, the required fraction of the upgraded sensors is \frac{x}{7x} =\frac{1}{7}. (Answer)
