Question

Solve the problems.1 A computer performs a calculation in 45 X 10-5 seconds to solve a math problem.How long does the computer need to calculate the solutions to 3 x 100 math problems?Write your answer in standard form,Show your work.Answer in seconds

Answer 1

time per math problem = 4.5 x 10 ^-5

number of math problems= 3 x 10^6

Multiply both expressions:

4.5 x 10^-5 x 3x 10 ^6

(4.5 x 3 ) ( 10^[-5+6] )

13.5 x 10^1 = 135

135 seconds
