The correct answer is the one you have selected
Answer:
Step-by-step explanation:
1 cubic foot is 12 * 12 * 12 cubic inches.
1 cubic foot = 1728 cubic inches.
1 cubic foot = 1728 cubic inches
x cubic feet = 3456 Cross multiply
1728 x = 3456 * 1 Divide by 1728
x = 3456/1728
x = 2 cubic feet.
The other way to do this is
3456 cu inches [1 cubic Foot/1728 cubic inches] note that the units cancel and you are left with 1 division problem.
The question still comes to 2.
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:
y = 1
Step-by-step explanation:
6 = 2(y + 2)
6 = 2y + 4
-4 -4
