Answer:
3B
Step-by-step explanation:
The greatest common factor is the greatest number that will divide two values. We have two values 3B and 30B. Each has numbers which multiply together to give the number. We need to find the highest value or most in common they share. Each has the factors:
3B: 1,3,B
30B: 1, 3, 5, 6, 10, B
Both have 3 and B has factors. Our GCF is these two factors.
The 565 on 11.9 has better gas mileage because you have to find how many miles in one gallon which is 565/11.9=43.2 and for 619/17.2= 35.9. which one is higher 43.2 how this helps.
Answer:
The sum of geometric series 6 - 4 + 8/3 - 16/9 + 32/17 is 4.0416
Step-by-step explanation:
We need to find the sum of geometric series 6 - 4 + 8/3 - 16/9 + 32/17
The formula used to find sum of geometric series is ![S_n=\frac{a(1-r^n)}{1-r}](https://tex.z-dn.net/?f=S_n%3D%5Cfrac%7Ba%281-r%5En%29%7D%7B1-r%7D)
where a is 1st term, n is number of terms and r is common ratio
so, in the given geometric series 6 - 4 + 8/3 - 16/9 + 32/17 we have
First Term a=6
Common ratio r= -0.6
Number of terms n= 5
Putting values in formula to find sum of given geometric series
![S_n=\frac{a(1-r^n)}{1-r}\\S_n=\frac{6(1-(-0.6)^5 )}{1-(-0.6)}\\S_n=\frac{6(1-(-0.07776))}{1+0.6}\\S_n=\frac{6(1+0.07776)}{1.6}\\S_n=\frac{6.46656}{1.6}\\S_n=4.0416](https://tex.z-dn.net/?f=S_n%3D%5Cfrac%7Ba%281-r%5En%29%7D%7B1-r%7D%5C%5CS_n%3D%5Cfrac%7B6%281-%28-0.6%29%5E5%20%29%7D%7B1-%28-0.6%29%7D%5C%5CS_n%3D%5Cfrac%7B6%281-%28-0.07776%29%29%7D%7B1%2B0.6%7D%5C%5CS_n%3D%5Cfrac%7B6%281%2B0.07776%29%7D%7B1.6%7D%5C%5CS_n%3D%5Cfrac%7B6.46656%7D%7B1.6%7D%5C%5CS_n%3D4.0416)
So, the sum of geometric series 6 - 4 + 8/3 - 16/9 + 32/17 is 4.0416
Answer: You would divide by six from both sides to isolate the x and get your answer, hope this helps.
