Answer:
1. 8.03 x 108 2. 6.8 × 10-9 3. 135,900 4. 2.5x10^-11
Step-by-step explanation:
Step 1
To find a, take the number and move a decimal place to the right one position.
Original Number: 803,000,000New Number: 8.03000000Step 2
Now, to find b, count how many places to the right of the decimal.
New Number:8.03000000Decimal Count:12345678
There are 8 places to the right of the decimal place.
Step 3
Building upon what we know above, we can now reconstruct the number into scientific notation.
Remember, the notation is: a x 10b
a = 8.03 (Please notice any zeroes on the end have been removed)
b = 8
Now the whole thing:
8.03 x 108
Step 4
Check your work:
108 = 100,000,000 x 8.03 = 803,000,000
Answer:
8.7%
Step-by-step explanation:
Well the net sales of Quarter 1 = 115 whilst the net sales of Quarter 2 = 125.
So the difference in the 2 numbers is 125-115 = 10
To find percentage change, you do 10/115 = 0.0869565217
Then, 0.0869565217 x 100 = 8.7% change to 1 decimal point.
So your percentage change is 8.7%.
