The ratio of width to height is 5 to 8. Using this ratio, you can determine the lengths.
1. 5/8=10/x
5x=80
x=16in
2. 5/8=15/x
5x=120
x=24in
3. 5/8 = 8/x
5x=64
x=12.8in

Find a8 in the arithmetic sequence with a1=-7 and d=0.5

gavmur [86]

$\bf n^{th}\textit{ term of an arithmetic sequence}\\\\
a_n=a_1+(n-1)d\qquad 
\begin{cases}
n=n^{th}\ term\\
a_1=\textit{first term's value}\\
d=\textit{common difference}\\
----------\\
a_1=-7\\
d=0.5\\
n=8
\end{cases}
\\\\\\
a_8=a_1+(8-1)d\implies a_8=-7+(8-1)(0.5)$

and surely you know how much that is.
