Answer:
Step-by-step explanation:
Answer:
(x, y) ⇒ (x -7, y)
Step-by-step explanation:
The y-coordinates are unchanged. Each x-coordinate of the image is 7 units less than the corresponding pre-image coordinate. As a rule, this is ...
(x, y) ⇒ (x -7, y)
No because if you were to make 7/3 a mixed fraction, it would be 2 and 1/3. Thus, they are different lengths on the number line
cells were not burnt when Jennie escaped from the fire.
<u>Solution:</u>
Given:
2% of skin cells were burnt i.e,
of skin cells were burnt.
To find:
Number of skin cells that were not burnt
We can write ![3.7\times10^{10} \text{ as } 37\times10^{9}](https://tex.z-dn.net/?f=3.7%5Ctimes10%5E%7B10%7D%20%5Ctext%7B%20as%20%7D%2037%5Ctimes10%5E%7B9%7D)
Therefore, by equating the values we get,
2% of the cell is ![37\times10^9](https://tex.z-dn.net/?f=37%5Ctimes10%5E9)
1% of the cell is ![\frac{37\times10^9}{3}=18.5\times10^9](https://tex.z-dn.net/?f=%5Cfrac%7B37%5Ctimes10%5E9%7D%7B3%7D%3D18.5%5Ctimes10%5E9)
As, 1% of the cell is ![18.5\times10^9](https://tex.z-dn.net/?f=18.5%5Ctimes10%5E9)
98% of the cell will be ![98\times18.5\times10^9=1813\times10^9](https://tex.z-dn.net/?f=98%5Ctimes18.5%5Ctimes10%5E9%3D1813%5Ctimes10%5E9)
![\therefore \text{ skin cells that are not burnt is } 1813\times10^9](https://tex.z-dn.net/?f=%5Ctherefore%20%5Ctext%7B%20skin%20cells%20that%20are%20not%20burnt%20is%20%7D%201813%5Ctimes10%5E9)
