(b) What is 0.36 (Six is Repeating) expressed as a fraction in simplest form?

Ugo [173]

A = 0.366666 ... = 0.3(6)

10a = 3.(6)
100 a = 36.(6)
100a - 10a = 36.(6) - 3.(6)
90a = 33
a=33/90=11/30

16. Joe has 5 sports cards. He bought 3 packs with

faust18 [17]

We can write an equation like; 5 + 3x = 35

Steps to solve:

5 - 5 + 3x = 35 - 5

3x = 30

3x/3 = 30/3

x = 10

There were 10 cards per pack.

Best of Luck!

the first term of an arithmetic sequence is equal to 200 and the common differencence is equal to -10. find the value of the 20t

olga_2 [115]

Answer:

The value for 20th term is 10.

Step-by-step explanation:

First, you have to find the formula for the sequence.

$an = a + d(n - 1)$

$let \: a = 200,d = - 10$

$an = 200 - 10(n - 1)$

$an = 200 - 10n + 10$

$an = - 10n + 210$

Given that the formula of this sequence is an = -10n + 210. Next, you have to find 20th term :

$let \:n = 20$

$20th \: term = - 10(20) + 210$

$20th \: term = - 200 + 210$

$20th \: term = 10$

(Correct me if I am wrong)
