eduard

Answer:

93%

Step-by-step explanation:

1 + 3 + 21 + 35 = 60 = 100%

21 + 35 = 56 = x%

60 = 100%

56 = x%

60x = 56 * 100

x = 56* 100 / 60

x = 2*23*2*2*5*5 / 2*2*3*5

x = 23*2*5/3

x = 93%

Evaluate the geometric series. Help me!!
aleksklad [387]

Answer:

255

Step-by-step explanation:

The n th term of a geometric series is

a_{n} = a(r)^{n-1}

where a is the first term and r the common ratio

1(2)^{n-1} ← is the n th term

with a = 1 and r = 2

The sum to n terms of a geometric series is

S_{n} = \frac{a(r^n-1)}{r-1}, thus

S_{8} = \frac{1(2^8-1)}{2-1}

    = 2^{8} - 1 = 256 - 1 = 255

julsineya [31]

Answer:

Step-by-step explanation:

Method A

34.54\div\pi\approx11

Method B

3\pi*11=33\pi

4\pi*11=44\pi

44\pi-33\pi=11\pi
