In order to add or subtract numbers expressed in scientific notation, it is important that the powers of 10 in the numbers should have the same index or else you cannot readily add or ubtract these numbers. We do as follows:<span>
a. 5.80 x 10^9 s +3.20 x 10^8 s
We need to adjust one of the numbers since they do not have the same indices. We move one place to the left of the second number making it .320 x 10^9 s. Then, we can add the numbers now:
</span>5.80 x 10^9 s +.320 x 10^9 s = 6.12 x 10^9 s<span>
b. 4.87 x 10^-6 m - 1.93 x 10^-6 m
We can subtract the numbers directly since they have the same indices.
</span>4.87 x 10^-6 m - 1.93 x 10^-6 m = 2.94 x 10^-6 m
Answer:
(B) 39
Explanation:
Use synthetic division:
-2 | 3 0 -1 3 1
____<u>-6 12 -22 38</u>
3 -6 11 -19 | 39
This means that the remainder is 39
Total hours is 3.35 hours
<u>Explanation:</u>
Given:
convert 3 hours 21 minutes to decimal hours
We know:
1 hour = 60 minutes
and
1 minute = 60 seconds
1 minute = 1 / 60 hours
So,
21 minutes = 
= 0.35 hours
Total hours would be = 3 hours + 0.35 hours
= 3.35 hours
Therefore, total hours is 3.35 hours
