Answer:
3/40
Step-by-step explanation:
Find the GCD (or HCF) of numerator and denominator
GCD of 9 and 120 is 3
Divide both the numerator and denominator by the GCD
9 ÷ 3
120 ÷ 3
Reduced fraction:
3/40
Answer:
Gregory gets 4 coffee for free and the total number of coffee he gets is 16.
Step-by-step explanation:
Given that when customers pay for 3 coffees, they get another coffee free.
So, for the cost of 3 coffee, 1 coffee is free.
Therefore, for the cost of 3n coffee, n coffee is free.
As Gregory pays for 12=3x4 coffees, the number of free coffee, n=4.
So, the total number of coffee Gregory = 12+4=16.
Hence, Gregory gets 4 coffee for free and the total number of coffee he gets is 16.
Answer:
Step-by-step explanation:
<u>Sum of infinite GP is</u>:
<u>The second term is</u>:
<u>Eliminate r in the system:</u>
- a/(1-r) = 16 ⇒ a = 16 - 16r ⇒ 16r = 16 - a ⇒ r = 1 - a/16
- ar = -0.5 ⇒ r = -0.5/a
<u>Compare the two equations and solve for a:</u>
<u>Multiply both sides by 16a:</u>
- 16a - a² = -8
- a² - 16a = 8
- a² - 16a + 64 = 72
- (a - 8)² = 72
- a - 8 = ±√72
- a = 8 ± √72
- a = 8 + 6√2
- a = 8 - 6√2, excluded as it is negative and makes common difference positive and so an increasing function
a = 8 - 6√2 = -0.4852 ⇒ r = -0.5/a = -0.5/-0.4852 = 1.03 > 1
