Answer:
The decimal number 8,500,000 has been converted to its corresponding scientific notation, which is .
Step-by-step explanation:
- Given: The decimal number 8,500,000.
- We need to convert the number to its corresponding scientific notation.
- Dissociate the number into the multiples of 10.
- Adjust the coefficient such that it lies between 1 and 10.
- Use the format to write the final answer.
Step 1 of 1
Remember that the decimal lies at the end of 8,500,000. Move the decimal next to 8 such that the result is greater than 1 and less than 10 . So the decimal point will move 6 places to the left.
As 8,500,000 is greater than 1 so the power of 10 will have an exponent of 6 .
So,
Verifying the result we can see that
when multiplied by 8.5 will result in 8,500,000.
Answer:
x = 8, -8
When taking an absolute value the sign of a number is ignored. Therefore, both 8 and -8 would come out equalling 8.
Answer:
A) y>=-1
Step-by-step explanation:
The line itself is y=-1, but it is also filled in. Therefore, we are down to either A or C as the right answer
Since (0,0) is a solution to the inequality as indicated by the shade, we know that since y=0 in the origin, 0 is greater than -1, so therefore A is the correct answer.
Answer:10
Step-by-step explanation:
Answer:
2/3 hour
Step-by-step explanation:
We can add the fractions, then multiply by the time, or we can multiply each by the time and add the results.
(1/5 +1/3)(1 1/4) = (8/15)(5/4) = (4·2·5)/(3·5·4) = 2/3 . . . hours
alternatively, ...
(1/5)(1 1/4) +(1/3)(1 1/4) = (1/5)(5/4) +(1/3)(5/4)
= 1/4 +5/12 = 3/12 +5/12 = 8/12 = 2/3 . . . hours
It takes Marty 2/3 hours (40 minutes) to shower and eat breakfast.
