Margarita [4]

Answer: The length of pencil is 16 centimetres and length of crayons is 8 centimetres

Step-by-step explanation:

Let the length of crayon = $x$

Length of a pencil = $2x$

As according to question that the sum of their length is 24 centimetres

So we have

$x+2x=24\\\\\Rightarrow 3x= 24 \\\\\Rightarrow x= \dfrac{24}{3} =8$

Therefore the length of crayon = 8 centimetres

Length of pencil= $2x= 2\times x = 2\times 8 =16$ centimetres

Hence, the length of pencil is 16 centimetres and length of crayons is 8 centimetres

Determine the 8th term in the geometric sequence whose first term is -10 and whose common ratio is 2

enyata [817]

$\bf n^{th}\textit{ term of a geometric sequence}
\\\\
a_n=a_1\cdot r^{n-1}\qquad 
\begin{cases}
n=n^{th}\ term\\
a_1=\textit{first term's value}\\
r=\textit{common ratio}\\
----------\\
a_1=-10\\
r=2\\
n=8
\end{cases}
\\\\\\
a_8=-10\cdot 2^{8-1}\implies a_8=-10\cdot 2^7
\\\\\\
a_8=-10\cdot 128\implies a_8=-1280$
