Answer:
50
..............................
Well we know the algae doubles three times.
So take 50 x 2 = 100
take 100 x 2= 200
200 x 2 = 400
So the answer is A

With Rule of concurrency of two triangles, we have,
![\frac{Angle1}{Side1} = \frac{Corresponding Angle}{Corresponding Side}](https://tex.z-dn.net/?f=%5Cfrac%7BAngle1%7D%7BSide1%7D%20%20%3D%20%5Cfrac%7BCorresponding%20Angle%7D%7BCorresponding%20Side%7D)
⇒![\frac{x+2}{13} = \frac{37}{14}](https://tex.z-dn.net/?f=%5Cfrac%7Bx%2B2%7D%7B13%7D%20%3D%20%5Cfrac%7B37%7D%7B14%7D)
⇒ ![14(x+2) = 37(13)](https://tex.z-dn.net/?f=14%28x%2B2%29%20%3D%2037%2813%29)
⇒ ![14x + 28 = 481](https://tex.z-dn.net/?f=14x%20%2B%2028%20%3D%20481)
⇒![14x = 453](https://tex.z-dn.net/?f=14x%20%3D%20453)
⇒ ![x = \frac{453}{14}](https://tex.z-dn.net/?f=x%20%3D%20%5Cfrac%7B453%7D%7B14%7D)
On simplifications, ![x = 32.37](https://tex.z-dn.net/?f=x%20%3D%2032.37)
∴Range of values of x is

Answer:
66/25
Step-by-step explanation:
A decimal is the same this as a fraction just in a different form, for example .1 = 1/10 and .01=1/100 so you can turn .64 into 64/100. So now we have 2 and 64/100, which is a mixed number, but you want the whole thing as just a fraction so 2 = 200/100, so add the two together and you get 264/100. Then you just simplify
