Let the time taken by computer for virus scan be, 'x' days
We are given that Computer A runs a virus scan in every 2.75 days and Computer B runs a virus scan in every 3.5 days.
<h3>Amount of work done by computer A⤵️</h3>
Amount of work done in one day = 
Amount of work done in x days = 
<h3>Amount of work done by Computer B⤵️</h3>
Amount of work done in one day = 
Amount of work done in x days = 
Since, They are doing the same work the amount of work done is 1.

Solve for x ~






➪ <em>Thus, the time taken when both computers run a virus scan at the same time again is, 1.54 days</em>
Answer:

Step-by-step explanation:
- Simplify:

I hope this helps!
The decimal representation of any number is a linear combination of powers of 10. In other words, given a number like 123.456, we can expand it as

for any
, so the above is the same as

Similarly, we can write

Now it's a question of reducing the fraction as much as possible. We have
so

Answer:
118
Step-by-step explanation:
the length ED is equal to EC
so
the angle is also the same
that's mean the angle ECD is equal to 31
then to find the another angle just do like this
=180–31–31
=118
First we want to know the surface of the circle, which is

with r representing the radius. In this case


To find the volume of the cylinder we have to multiply this outcome with the height.



Hence, the volume of the cylinder is about 5024 cubic cm.
