Evaluate 1 whole number 2/5 + 3/4 and give your answer to one significant figure

ehidna [41]

Answer:

The answer is

<h3>2 to 1 significant figure</h3>

Step-by-step explanation:

$1 \frac{2}{5} + \frac{3}{4}$

To solve the question first convert the mixed fraction to an improper fraction

That's

$1 \frac{2}{5} = \frac{7}{5}$

So we have

$\frac{7}{5} + \frac{3}{4}$

Find the LCM of the fractions

The LCM of 5 and 4 is 20

That's

$\frac{7}{5} + \frac{3}{4} = \frac{7(4) + 3(5)}{20} = \frac{28 + 15}{20}$

$= \frac{43}{20}$

= 2.15

We have the final answer as

<h3>2 to 1 significant figure</h3>

Hope this helps you

Liula [17]

40,000 divided by 20 = 500
500 x 12 (which was 20-8)= 6,000

Which formula can be used to find the nth term of a geometric sequence where the fifth term is 1/6 and the common ratio is 1/4?

OlgaM077 [116]

Answer:

$a_n = 16(\frac{1}{4})^{n - 1}$

Step-by-step explanation:

Given:

Fifth term of a geometric sequence = $\frac{1}{16}$

Common ratio (r) = ¼

Required:

Formula for the nth term of the geometric sequence

Solution:

Step 1: find the first term of the sequence

Formula for nth term of a geometric sequence = $ar^{n - 1}$ , where:

a = first term

r = common ratio = ¼

Thus, we are given the 5th term to be ¹/16, so n here = 5.

Input all these values into the formula to find a, the first term.

$\frac{1}{16} = a*\frac{1}{4}^{5 - 1}$

$\frac{1}{16} = a*\frac{1}{4}^{4}$

$\frac{1}{16} = a*\frac{1}{256}$

$\frac{1}{16} = \frac{a}{256}$

Cross multiply

$1*256 = a*16$

Divide both sides by 16

$\frac{256}{16} = \frac{16a}{16}$

$16 = a$

$a = 16$

Step 2: input the value of a and r to find the nth term formula of the sequence

nth term = $ar^{n - 1}$

nth term = $16*\frac{1}{4}^{n - 1}$

$a_n = 16(\frac{1}{4})^{n - 1}$
