Answer:

C. 168°

Step-by-step explanation:

The exterior angle at any vertex of an n-gon will be ...

360°/n

So a 30-gon will have exterior angles of ...

360°/30 = 12°

The adjacent interior angle is supplementary to this, so is ...

180° -12° = 168°

_____

<em>Using the reasonableness test</em>

You know that the interior angles of a square are 90°, and that regular polygons with more sides have larger interior angles. The most any regular polygon's interior angle can be is 180°. The only answer choice between 90° and 180° is the correct choice: 168°.

Rewrite in simplest radical form square root of x times the fourth root of x. Show each step of your process.

Answer:

$\sqrt[4] {x^3}$

Step-by-step explanation:

At this point, we can transform the square root into a fourth root by squaring the argument, and bring into the other root:

$\sqrt x \cdot \sqrt[4] x =\sqrt [4] {x^2} \cdot \sqrt[4] x = \sqrt[4]{x^2\cdot x} = \sqrt[4] {x^3}$

Alternatively, if you're allowed to use rational exponents, we can convert everything:

$\sqrt x \cdot \sqrt[4] x = x^{\frac12} \cdot x^\frac14 = x^{\frac12 +\frac14}= x^{\frac24 +\frac14}= x^\frac34 = \sqrt[4] {x^3}$

If 4 gal of premium unleaded gasoline costs $15.04, how much would it cost to completely fill a tank whose capacity is 9-gal?

Sveta_85 [38]

Answer:

$33.84 cents

Step-by-step explanation:

Given the following question:

4 gallons = 15.04
1 gallon = ?

How much for 9 gallons?

To find the answer we have to find how much one-gallon costs since we already know how much it costs for 4 gallons of this unleaded gasoline.

$15.04\div4$
$15.04\div4=3.76$
$=3.76$

One gallon of this gasoline costs $3.76 now we need to find how much it costs for 9 gallons.

$3.76\times9=33.84$
$=33.84$

For nine gallons of gasoline it will cost you "$33.84 cents."

Hope this helps.
