Sum of odd numbers from 1 to 100?

Mathematics
1 answer:
Igoryamba3 years ago
4 0

Series would be: 1,3,5......99

Here, a=1, d = 3-1 = 2, l = 99

l = a+(n-1)d

99 = 1+(n-1)2

98 = 2n-2

2n = 100

n = 50

Sum would be Sn = n/2 (a+l)

 50/2 (1+99)

 25(100) = 2500

So, your answer is 2500

100 POINTS! :)
nasty-shy [4]

Answer: So we'll use trig to solve this because it's a right triangle. The hypotenuse is the ladder (h) and the two smaller sides are the ground and the vertical wall (w).

That angle ladder makes with the ground = €

SOH: sin € = opposite/hypotenuse

No the ladder won't be safe!!!

Now let's make it safe:

The ladder's length (w) is constant, so stays 12

So now let's ask in an inequality what height will be safe (75° or less)

what does that mean?? well as long as you put the ladder against the wall so that the height from ground to top of the ladder is < 11.6 ft!!

Hope that helps! :-D
