What is the seventh term of a sequence whose first term is 1 and whose common ratio is 3?

ikadub [295]

$\bf n^{th}\textit{ term of a geometric sequence}\\\\
a_n=a_1\cdot r^{n-1}\qquad 
\begin{cases}
n=n^{th}\ term\\
a_1=\textit{first term's value}\\
r=\textit{common ratio}\\
----------\\
a_1=1\\
r=3\\
n=7
\end{cases}
\\\\\\
a_7=1\cdot 3^{7-1}\implies a_7=1\cdot 3^6\implies a_7=1\cdot 729\implies a_7=729$

when a spherical balloon is filled with air, it has a radius of 3 inches. what is the estimate for the volume of air in the ball

Crazy boy [7]

The volume of a sphere is given by the equation $V=\frac{4}{3} \pi r^{3}$ , where V is the volume and r is the radius.

To answer this question, simply plug the correct values into the equation:

$V=\frac{4}{3} \pi 3^{3} \\V=4.1888(27)\\V=113.0976$

The volume of the air in the balloon is about 113.0976 in3.

Hope this helps!!

a sum of RS 500 is in the form of denominators of RS5 & RS 10..if the total no. of notes is 90 ,find the no. of notes of eac

Katarina [22]

Let rs.5 denominations be x , then rs 10 denominations will be 90-x

then total amount 5x + 10(90-x) which is rs.500

5x + 10(90-x) = 500

900 - 5x = 500
400 = 5x
therefore x = 80
therefore no. of rs.5 is 80
no. of rs.10 is 90-x = 90-80 = 10
