Answer: Option 'A' is correct.

Step-by-step explanation:

Since we have given that

Geometric series is as follows:

1,3,9,................

Number of terms = 10

n = 10

a = 1

r = \dfrac{a_2}{a_1}=\dfrac{3}{1}=3

We need to find the sum of the geometric sequence for 10 terms.

S_{10}=\dfrac{a(r^n-1}{r-1}\\\\S_{10}=\dfrac{1(3^{10}-1)}{3-1}\\\\S_{10}=\dfrac{59048}{2}\\\\S_{10}=29,524

Hence, Option 'A' is correct.

ryzh [129]
<h3>Given</h3>

burned : unburned = 1 : 3

<h3>Find</h3>

burned/total as a percentage

<h3>Solution</h3>

burned : total = burned : (burned + unburned) = 1 : (1+3) = 1 : 4

As a fraction, this is 1/4 = 0.25 = 25%

25% of the total cookies were burned.

_____

"%" is a fancy way to write "/100". You know from place value that 0.25 (twenty-five hundredths) is 25/100, so that can also be written as 25%.
