Answer:
![8.51x10^{-3}cm](https://tex.z-dn.net/?f=8.51x10%5E%7B-3%7Dcm)
Step-by-step explanation:
In order to add or subtract numbers in scientific notation, the powers of ten must have the same exponent. In this caes the diameter of an average human body cell is a power of -4 and the diameter of a plant cell is a power of -3. In order to add them, we can move the decimal over for the body cell diameter:
![5.1x10^{-4}=0.51x10^{-3}](https://tex.z-dn.net/?f=5.1x10%5E%7B-4%7D%3D0.51x10%5E%7B-3%7D)
Add the two values: ![0.51x10^{-3}+8x10^{-3}=8.51x10^{-3}cm](https://tex.z-dn.net/?f=0.51x10%5E%7B-3%7D%2B8x10%5E%7B-3%7D%3D8.51x10%5E%7B-3%7Dcm)
The answer is 75! Explanation, use the distance formula
Answer:
A
Step-by-step explanation:
1. Get 15% of 870:
First, get 10 percent of 870, which is 87, then half that, which is 43.5
Get the 87 and add the 43.5 on it, to get the full 15%, you end up with $130.5, which is the monthly payment.
(Only problem is that im pretty sure you put an extra 0, because if you just wrote 87 dollar's then you would've got 13.05, the actual answer, but if you add an extra 0 then you end up with 130$, just to let you know.)
