Answer:
The correct scientific notation for the number 500.0 is
Step-by-step explanation:
While writing a large number in scientific notation we do below mentioned two things.
- We take any number between 1 and 10
- Then we multiply this number with an exponent of 10.
Hence, any number in scientific notation is in the form
Here a is any number between 1 and 10.
b is exponent of 10.
Now, writing 500 in scientific notation, we take a = 5
Hence, we have to take b = 2, since 5 multiplied by 100 equas 500.
Thus, we have
1/3 of an hour = 20 minutes
8 hours = 480 minutes
So to find the number of periods we divide 480 by 20. Answer is 24
Let x = hours to meet
train one has a 2 hour head start or 210 km head start
210 + 105x = 135x
30x = 210
x = 7 hours to meet
Answer:
$36.94
Step-by-step explanation:
Okay, so. This is what we do. There is two magazines and they cost 9.95 each multiply 9.95 times 2
9.95 x 2 = 19.90
Okay, then he buys a book for 14.95 we add 19.9. and 14.95
19.90 + 14.95 = 34.85
Then we have a sales tax of 6% we would multiply 34.85 time 6%
34.85 x 6% = 2.09
Then we would add. 34.85 + 2.09
34.85 + 2.09 = 36.94
Therefore your answer is $36.94
Hope this helps!!!
