Step-by-step explanation:
Answer:
7
Step-by-step explanation:
7x2=14
14+6=20
Answer:
55
Step-by-step explanation:
To solve the expression, ![\sqrt[3]{\frac{n}{4}} + \frac{n}{10}](https://tex.z-dn.net/?f=%5Csqrt%5B3%5D%7B%5Cfrac%7Bn%7D%7B4%7D%7D%20%2B%20%5Cfrac%7Bn%7D%7B10%7D)
substitute n = 500 and simplify according to order of operations.
![\sqrt[3]{\frac{500}{4} } + \frac{500}{10}\\\\\sqrt[3]{125}+50\\ 5+50\\\\55](https://tex.z-dn.net/?f=%5Csqrt%5B3%5D%7B%5Cfrac%7B500%7D%7B4%7D%20%7D%20%2B%20%5Cfrac%7B500%7D%7B10%7D%5C%5C%5C%5C%5Csqrt%5B3%5D%7B125%7D%2B50%5C%5C%205%2B50%5C%5C%5C%5C55)
Step-by-step explanation:
Rate of growth equals 420/100 = 4.2 times per hour
So after t=three hours,
size of culture = 100*(4.2)^t = 100*4.2^3=7408.8 bacteria,
round to nearest unit 7409 bacteria after three hours (after initial size of 100).
