The common ratio in a geometric series is 0.5 and the first term is 256. Find the sum of the first 6 terms in the series

Svetach [21]

Answer:

The sum of the first 6 terms of the series is 504.

Step-by-step explanation:

Given that,

Common ratio in a geometric series is, r = 0.5

First term of the series, a = 256

We need to find the sum of the first 6 terms in the series. If a and r area the first term and common ratio of a series, then the series becomes:

$a,ar^1,ar^2,ar^3......$

The sum of n terms of a GP is given by :

$S_n=\dfrac{a(1-r^n)}{1-r}$

Here, n = 6

$S_n=\dfrac{256\times (1-(0.5)^6)}{1-0.5}\\\\S_n=504$

So, the sum of the first 6 terms of the series is 504.

b = 24 birds ($72)
c = 6 cats ($51)

51+72=123

There were 24 birds at the shelter on Tuesday.

The value of y in 4(2y – 3) + 12 = 40 is _________

Aliun [14]

Answer:

y =5

Step-by-step explanation:

Let's solve your equation step-by-step.

4(2y−3)+12=40

Step 1: Simplify both sides of the equation.

4(2y−3)+12=40

(4)(2y)+(4)(−3)+12=40(Distribute)

8y+−12+12=40

(8y)+(−12+12)=40(Combine Like Terms)

8y=40

Step 2: Divide both sides by 8.

y=5
