The way I would look at it is that Sophia types 15 words per minute faster than Patty so every minute Sophia is 15 minutes closer to what Patty has done. 510/15=34 so after 34 minutes Sophia will have caught up to Patty
At hour one, there is 1 organism. At hour two, there is five more organism. At hour three. there will be 6 x 5 = 30 more organisms, etc
This is a geometric sequence with a = 1 (i.e. number of organisms at hour one), r = 5 (number of reprications per hour).
The total number of organisms at hour seven is the sum of the first seven terms of the sequence given by a(r^n - 1)/(r - 1) = 1(5^7 - 1)/(5 - 1) = (78125 - 1)/4 = 78124/4 = 19,531
Answer:
8.333333333 or 25
/3
Step-by-step explanation:
Answer: 
Step-by-step explanation:
Since, in the triangle abc,
ab = 10√91 unit, bc = 30 unit, ca = 100 unit and m∠b = 90°
⇒ 
⇒ 
⇒ 
⇒ 
⇒ 
Which is the required value of tan(∠a).
