The sum of an Arithmetic Series is given as:

where,
d = Common Difference = Difference of any two consecutive terms.
So,
d = 8
a1 = First term = 1
Using the values, we get:

The above equation gives the formula for n terms of an Arithmetic Series.
So, option A is the correct answer
Answer:
9670 feet
Step-by-step explanation:
The height given (8219.5 ft) is 85% OF ORIGINAL, hence original is much higher. But how do we figure this out?
<em>we translate word problem to equation.</em>
<em />
<em>8219.5 IS 85% of TOTAL</em>
<em />
Firstly, 85% = 85/100 = 0.85
Remember, is means =
of means multiplication
So we have:
<em>8219.5 = 0.85 * Total</em>
<em>Hence, total = [let total be 7]</em>
<em>8219.5 = 0.85 * t</em>
<em>t = 8219.5/0.85 = </em><em>9670 feet</em>
Answer:
it would range between 11.28379... to 13.819765...
Step-by-step explanation:
the circle's area formula is pi * radius^2
so you make to equation, plugging the 100 and 150 into the circle's area
you get square root of (100/pi) which gets 11.28379... for the area of 100
you do the same with 150 to get square root of (150/pi) which gets 13.819765...
those are the diameter of the circle since the diameter is double the radius which i already multiplied afterwards. so if you need the radius divide the number ive given you
You're doing it exactly right! Keep on going! :)
