Answer:
Example 11 answer = 12
Step-by-step explanation:
40, 36, 32, 28
is an arithmetic sequence.
The first term (a) is 40
The common difference (d) is -4
The formula for finding the nth term (
in an arithmetic sequence is;
= a + d(n - 1)
= 40 + -4(8 - 1)
= 40 - 28 = 12
Since you have the length and the area, you can assume the width
1496/44 = Width Because Area = L * W
Width = 34
So this is a ratio problem
44/11 = ratio
So, the ratio is 4:1
So since we have the width, we can divide the width of the school banner by 4 because of the scale
34/4 = 8.5 = width of the sign
The area of the sign is 8.5*11 = 93.5
and the perimeter is just that,
8.5 * 2 + 11*2 = 39
Perimeter = 39 inches
Area = 93.5 inches²
