Scientific notation is a way of writing very large or very small numbers. A number is written in scientific notation when a number between 1 and 10 is multiplied by a power of 10. For example, 650,000,000 can be written in scientific notation as 6.5 ✕ 10^8.
Answer:
The smaller angle = 31°
The larger angle = 149°
Step-by-step explanation:
The sum of two supplementary angles = 180 degrees
Lets x = the smaller angle
larger angle = 5x - 6
So now you have the equation:
x + 5x - 6 = 180
6x - 6 = 180
6x = 186
x = 31
The smaller angle = 31 degrees
The larger angle = 5(31) - 6 = 149 degrees
Answer:
Step-by-step explanation:
Given that in 10 minutes, the top 3 contestants of a hot dog eating contest consumed 136 hot dogs. The winner ate 9 more hot dogs than the runner-up, and the runner-up ate 8 more hot dogs than the third-place contestant.
Let winner up ate x hot dogs
Then runner up ate 9 less than the winner i.e. 
The third place contstant ate 8 less than runner up i.e.

Total ate by these three =

Winner ate 54, runner up ate 45 and third ate 37
1/10 + 1/6 = 4/15
4/15 is the answer
