We will use demonstration of recurrences<span>1) for n=1, 10= 5*1(1+1)=5*2=10, it is just
2) assume that the equation </span>10 + 30 + 60 + ... + 10n = 5n(n + 1) is true, <span>for all positive integers n>=1
</span>3) let's show that the equation<span> is also true for n+1, n>=1
</span><span>10 + 30 + 60 + ... + 10(n+1) = 5(n+1)(n + 2)
</span>let be N=n+1, N is integer because of n+1, so we have
<span>10 + 30 + 60 + ... + 10N = 5N(N+1), it is true according 2)
</span>so the equation<span> is also true for n+1,
</span>finally, 10 + 30 + 60 + ... + 10n = 5n(n + 1) is always true for all positive integers n.

2) The download speed for Bidmore is 1,500
3) The download speed for Comcast is 1,680
4) AT&T has the best download speed out of the three.
5) They will go through the origin and be a proportional line.
Step-by-step explanation:
Answer:
23:44 or 1:1.91
Step-by-step explanation:
w:l =69:132 Divide each number by 3
= 23:44 Divide each number by 23
≈ 1:1.91
The width-to-length ratio is 23:44 or approximately 1:1.91
Eight hundredths
0.08
You already got it with the number part ;)
