The average time it takes a computer to execute one instruction is measured in picoseconds. There are 3.6 × 10^15 picoseconds per hour. What fraction of a second is a picosecond?

Work Shown:

1 minute = 60 seconds

60 minutes = 60*60 = 3600 seconds

1 hour = 3600 seconds

1 hour = 3.6 * 10^15 picoseconds

3600 seconds = 3.6 * 10^15 picoseconds

3600/(3.6 * 10^15) seconds = (3.6 * 10^15)/(3.6 * 10^15) picoseconds

(3.6 * 10^3)/(3.6 * 10^15) seconds = 1 picosecond

(3.6/3.6) * 10^(3-15) seconds = 1 picosecond

1 * 10^(-12) seconds = 1 picosecond

1/(10^12) seconds = 1 picosecond

1/(1,000,000,000,000) seconds = 1 picosecond

one trillionth of a second = 1 picosecond

side note:

we can go from

1/(1,000,000,000,000) seconds = 1 picosecond

to

1 second = 1,000,000,000,000 picoseconds

after multiplying both sides by 1,000,000,000,000

The number 1,000,000,000,000 is read out as "one trillion". The number of zeros (12) is due to the exponent of 12 in 10^12.

black lol

step-by-step explanation:

h

i can tell you jamal now has 3 cookies xd

tommy has 2.

this made me lol.

1. x> -5

2. x< 8

step-by-step explanation:

1. 2x> -10

divide by 2 from both sides of equation.

2x/2> -10/2

simplify, to find the answer.

-10/2=-5

x> -5 is the correct answer.

2. 3x< 24

divide by 3 from both sides of equation.

3x/3< 24/3

simplify, to find the answer.

24/3=8

x< 8 is the correct answer.

i hope this you, and have a wonderful day!
