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.

Carter made a model of a boat. The length of the actual boat is 45 feet. Carter’s model has a length of 7 1/2 inches. What scale
Marysya12 [62]

Answer:

Option C)1 in. = 6 ft

Step-by-step explanation:

Up to know we have the following equality:

45 f = 7 1/2 in

Or what is the same that:

45 f = 7.5 in

If we divide both sides of the equation by 7.5 we will get the equivalence to 1 inch:

45/7.5 f = 7.5/7.5 in

6 = 1 in

So, the correct answer if option C)1 in. = 6 ft
