A car wheel has a diameter of 20.8 inches.

m_a_m_a [10]

Answer:

65.312 inches
326.56 inches
1959.36 inches

Step-by-step explanation:

<h3>Given</h3>

d = 20.8 inches

Travel in 1, 5, 30 rotations

<h3>Solution</h3>

<u>Circumference of the wheel is equal to one full rotation</u>

C = πd = 3.14*20.8 = 65.312 inches
5C = 5*65.312 = 326.56 inches
30C = 30*65.312 = 1959.36 inches

Ten times the sum of half a number and 6 is 8.

Sedaia [141]

That would be

$10( \frac{1}{2} n + 6) = 8$
$\frac{1}{2} n+6= \frac{8}{10}$
$.5n + 6 = .8$
$.5n = -5.2$
$n=-2.6$

Hope that helps :)

Which expression is equivalent to xy^2/9?

Law Incorporation [45]

Answer:

$xy^\frac{2}{9} = x*\sqrt[9]{y^2}$

Step-by-step explanation:

Given

$xy^\frac{2}{9}$

Required

The equivalent expression (see attachment)

We have:

$xy^\frac{2}{9}$

Split

$xy^\frac{2}{9} = x*y^\frac{2}{9}$

Apply the following laws of indices

$y^\frac{m}{n} = \sqrt[n]{y^m}$

So, we have:

$xy^\frac{2}{9} = x*\sqrt[9]{y^2}$

<em>Hence (d) is correct</em>
