first you add all the numbers, then divide by 3 and you get 8.6.
Answer:
B) 50
Step-by-step explanation:
40 + 50 = 90.
A right angle is 90 degrees.
90-40 = 50.

<h2>
A formula for the nth term in given arithmetic sequence = 0.5(n - 1) or, (n - 1)</h2>
Step-by-step explanation:
Given,
= 0, = 0.5, = 1, = 1.5, ...
To find, a formula for the nth term in given arithmetic sequence = ?
Here, first term (a) = = 0 and
common difference(d) = - = - = 0.5 - 0 = 0.5
We know that,
The nth term of the arithmetic sequence
Put a = 0 and d = 0.5, we get
= 0 +(n - 1)0.5
= 0.5(n - 1) or, (n - 1)
∴ A formula for the nth term in given arithmetic sequence = 0.5(n - 1) or, (n - 1)
Area = a
width = w
height = h
a = wh
h = (5/7)w
h = 5w/7
a = (5w/7)(w)
a = 140
140 = (5w/7)(w)
140 = (5w^2)/7
sqrt((140*7)/5) = w
14 = w
h = 5*14/7 = 10
Dimensions: height 10 inches, width 14 inches
