Answer:

It removes the repeating part of the decimal from the equation.

Step-by-step explanation:

Described here is the process of converting the repeating decimal fraction into fraction in the form of p/q

1) --------------

x = 0.555555

2) --------------

10x = 5.555555

3) --------------

10 x - x = 5.555555 - 0.555555
9x = 5
x = 5/9

So the purpose of step 3 here is to remove the repeating part of the decimal from the equation

Correct option is the first one.

Answer:

Step-by-step explanation:

(3 - 2i)(3 + 2i)

Expand

(9 + 6i - 6i - 4i^2)

Add

(9 - 4i^2)

Convert i^2

i^2 = ( $\sqrt{-1}$ )^2 = -1

(9 - 4(-1))

Add

(9 + 4)

= 13

Simplify [view attached image]

pav-90 [236]

<u>Given</u>:

The given expression is $(\sqrt{5})( \sqrt[3]{5})$

We need to simplify the given expression.

<u>Simplification</u>:

Let us simplify the given expression.

Rewriting the given expression, we have;

$5^{\frac{1}{2}} \cdot 5^{\frac{1}{3}}$

Let us apply the exponent rule $\:a^b\cdot \:a^c=a^{b+c}$ , we get;

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

Taking LCM, we have;

$5^{\frac{3+2}{6}}$

Simplifying, we get;

$5^{\frac{5}{6}}$

Thus, the simplified value of the given expression is $5^{\frac{5}{6}}$

Hence, Option a is the correct answer.

Hitman42 [59]

Answer:

Each hour he fly 107.76 miles

Step-by-step explanation:

we know that

Charles Lindbergh flew 3,610 miles in 33.5 hours

To find out the unit rate, divide the total distance by the total time

$\frac{3,610}{33.5}= 107.76\frac{miles}{hour}$

therefore

Each hour he fly 107.76 miles
