Answer:
16.25%
Step-by-step explanation:
520/3200 = 52/320 = 16.25%
24ft long, 12ft wide
2/.25=8 8x3=24
1/.25=4 4x3=12
Answer:
41.6 pounds
Step-by-step explanation:
x to represent the pounds of bread sold this week
208 = 5x
x = 208/5
x = 41.6
41.6 Pounds of bread were sold this week.
= 9n + 63
generate the first few terms using the recursive equation
f(1) = 72
f(2) = 72 + 9 = 81
f(3) = 81 + 9 = 90
f(4) = 90 + 9 = 99
the sequence is 72, 81, 90, 99, .....
This is an arithmetic sequence whose n th term formula is
=
+ (n - 1 )d
where
is the first term and d the common difference
d = 99 - 90 = 90 - 81 = 81 - 72 = 9 and
= 72
= 72 + 9(n - 1) = 72 + 9n - 9 = 9n + 63 ← explicit formula
