Answer:
5.5 hrs
Step-by-step explanation:
1 hr --> -0.8 hrs
? --> -4.4°C

Both circles middles are positive
SOLUTION:
Case: Percentages
Method:
The sale price after 30% off is $6800
Let the original price be 'x'
30% off means 70% of the original price
![\begin{gathered} \frac{70}{100}\times x=6800 \\ 0.7x=6800 \\ x=\frac{6800}{0.7} \\ x=9714.2857 \end{gathered}](https://tex.z-dn.net/?f=%5Cbegin%7Bgathered%7D%20%5Cfrac%7B70%7D%7B100%7D%5Ctimes%20x%3D6800%20%5C%5C%200.7x%3D6800%20%5C%5C%20x%3D%5Cfrac%7B6800%7D%7B0.7%7D%20%5C%5C%20x%3D9714.2857%20%5Cend%7Bgathered%7D)
Final answer: (Nearest cents)
The original price was $9714.29

Here, we need to write the length of the insect in scientific notation.
The given length of the insect is 0.0052 meter
Now, to write 0.0052 meter in scientific notation we need to follow this:
Scientific notation always start with non-zero digit followed by a decimal point.
Since in our number the decimal is needed to be moved three places to the right to get the first non-zero digit.
The exponent of the 10 is
.
![10^{-3}=\frac{1}{1000} =0.001](https://tex.z-dn.net/?f=10%5E%7B-3%7D%3D%5Cfrac%7B1%7D%7B1000%7D%20%3D0.001)
Therefore, our number 0.0052 can be written as:
![5.2 \times 10^{-3}](https://tex.z-dn.net/?f=5.2%20%5Ctimes%2010%5E%7B-3%7D)
Hence, the require scientific notation is
.
