A certain computer performs 1.5 x 10^8 calculations per second. How many seconds would it take this computer to perform 6.0 x 10^16 calculations? * A. 2.5 x 10^8 B. 4.0 x 10^8 C.4.0 x 10^2 D.9.0 x 10^24

Sagot :

Answer:

It is would take the computer

[tex]4.0\times10^8\text{ seconds}[/tex]

to perform

[tex]6.0\times10^{16}\text{ calculations}[/tex]

Explanation:

Given that the computer performs

[tex]\text{1}.5\times10^8[/tex]

per second.

We want to find how many seconds it woult take it to perform:

[tex]6.0\times10^{16}[/tex]

Let x represent the number of seconds it will take, then

[tex]\begin{gathered} 1.5\times10^8x=6.0\times10^{16} \\ \\ x=\frac{6.0\times10^{16}}{1.5\times10^8} \\ \\ =\frac{6.0}{1.5}\times10^{16-8} \\ \\ =4.0\times10^8 \end{gathered}[/tex]
