B is the closest answer, hope that helps
Three hundred nine thousand and seventeen
Answer:
About 3.7 times or 4 times.
Step-by-step explanation:
6.14 x 10 - 3 = 61.4-3
61.4 - 3 = 58.4
1.98 x 10 - 4 = 19.8 - 4
19.8 - 4 = 15.8
58.4 ÷ 15.8 = 3.696202531645569620253164556962 ≈ 3.7 times
The equation in terms of "t"
1/t = ¹/₂₁ + ¹/₁₅
On solving the equation "t"= 8 ³/₄ days
Step-by-step explanation:
Time taken by roofer to shingle a roof- 15 hours
Time taken by apprentice-21 hours
Time required to shingle if both worked together- “t” hours
If roofer shingles the roof in 15 hours
Part of the roof he would shingle in 1 hours= ¹/₁₅
Similarly, part of the roof shingled by apprentice in 1 hour- ¹/₂₁
Part of the roof shingles when they worked together for 1 hours- 1/t = ¹/₂₁ + ¹/₁₅
Total time taken= 1/t = ¹/₂₁ + ¹/₁₅
1/t= ⁽²¹⁺¹⁵⁾ /₃₁₅
t= 315/36 = 8 ³/₄ days
I'm not sure what the question is.
Given:
Flash drive capacity 1,000 megabytes
Initial content before transfer of files 36.5 megabytes
After 125 seconds, there were 549 megabytes on the drive.
549 - 36.5 = 512.5 megabytes is the weight of the transferred files.
512.50 megabytes / 125 seconds = 4.1 megabytes per second
The rate of transfer is 4.10 megabytes per second.
1000 - 549 = 451 megabytes free space.
451 megabytes / 4.1 megabytes per second = 110 seconds
It would take an additional 110 seconds to completely fill up the flash drive.
