andreyandreev [35.5K]

Answer:

$2.24

Step-by-step explanation:

Since we are trying to find a percentage of something, we can multiply whatever we're trying to find a percentage from by 0.X where X is equal to the number of the percentage. So in this case it's 15%. We can multiply $14.90 by 0.15 and we get 2.23500. Since we cannot have 2.235 dollars, we must round up decimal places.

The tip would be 2 dollars and 24 cents. ($2.24).

If a1 = 10 and an = 3an-1 then find the value of a6.

Black_prince [1.1K]

Answer:

a(6)=2430

Step-by-step explanation:

a(1)=10

a(n)=3×a(n-1)

This is a geometric sequence, with ratio=3

a(2)=3×a(1)=3×10

a(3)=3×a(2)=3²×10

a(6)=3⁵×20=(27×9)×10=243×10=2430
