Answer: See explanation
Step-by-step explanation:
1. Cost = $413
Sales percent = 6.5%
Cost of bike = $413 + (6.5% × $413)
= $413 + (0.065 × $413)
= $413 + $26.845
= $439.85
2. Cost of dishwasher = $569
Commission rate = 18%
The expression for the commission will be:
= 18% × $569
= 18/100 × $569
= 0.18($569)
The formula is the diameter times pi
3.14 x 30
the circumference is 94.2 centimeters
Answer:
The difference between the 4th term of both series is 7
Step-by-step explanation:
The formula for the nth term of an APS is a + (n - 1)×d
The first term of one of the series = -1
The first term of the other of the series = -8
The fourth term of both series is thus;
4th term first series = -1 + (4 - 1)× d = -1 + 3·d
4th term second series = -8 + (4 - 1)× d = -8 + 3·d
The difference between the 4th term of both series = -1 + 3·d - (-8 + 3·d)
-1 + 3·d - (-8 + 3·d) = -1 + 3·d + 8 - 3·d = 8 - 1 = 7
The difference between the 4th term of both series = 7.
