ill be in the bond after 4 hours
2 answers:
One that is a lot of algae
two 50 x 2 = 100 x 2 = 200 x 2 = 400 x 2 = 800
1 2 3 4
That is a lot of algae
800 pounds would be your answer after 4 hours
Answer:
250
Step-by-step explanation:
because 50 + (4 x 50) that equals 50 + 200 = 250

![10.3\ mi](https://tex.z-dn.net/?f=10.3%5C%20mi)
Step-by-step explanation:
we know that
the formula to calculate the distance between two points is equal to
![d=\sqrt{(y2-y1)^{2}+(x2-x1)^{2}}](https://tex.z-dn.net/?f=d%3D%5Csqrt%7B%28y2-y1%29%5E%7B2%7D%2B%28x2-x1%29%5E%7B2%7D%7D)
we have
substitute the values
![d=\sqrt{(3-8)^{2}+(1-10)^{2}}](https://tex.z-dn.net/?f=d%3D%5Csqrt%7B%283-8%29%5E%7B2%7D%2B%281-10%29%5E%7B2%7D%7D)
![d=\sqrt{(-5)^{2}+(-9)^{2}}](https://tex.z-dn.net/?f=d%3D%5Csqrt%7B%28-5%29%5E%7B2%7D%2B%28-9%29%5E%7B2%7D%7D)
![d=\sqrt{25+81}](https://tex.z-dn.net/?f=d%3D%5Csqrt%7B25%2B81%7D)
![d=\sqrt{106}](https://tex.z-dn.net/?f=d%3D%5Csqrt%7B106%7D)
![d=10.3\ mi](https://tex.z-dn.net/?f=d%3D10.3%5C%20mi)
