A store owner paid $15 dollars for a book. she marked up the price of the book by 40% to determine it's selling price.

Tcecarenko [31]

A) $15 ÷ 40% =
15×.4= 6
15+6= 21

B) $38 × .25=9.5
38-9.5=28.50

28.50×.06=1.71
28.50+1.17=30.21

I think this is how you do it. would wait for other answers as well to double check.

What is x equal to????

Ksju [112]

Answer:

x = 20

Step-by-step explanation:

The 3 arcs UV, VW, WX form a semicircle, so sum to 180° , that is

4x + 2 + x + 78 = 180

5x + 80 = 180 ( subtract 80 from both sides )

5x = 100 ( divide both sides by 5 )

x = 20

4^3 * 4^4 = <br> A) 4^-1<br> B) 4^1<br> C) 4^7<br> D) 4^12

<h2>Hello!</h2>

The answer is:

The correct option is:

C) $4^{3}*4^{4}=4^{7}$

To solve the problem, we need to remember the product of powers with the same base property, the property is defined by the following relation:

$a^{m}*a^{n}=a^{m+n}$

If we are multiplying two or more powers with the same base, we must keep the base and add/subtract the exponents.

So, we are given the expression:

$4^{3}*4^{4}$

We can see that both powers have the same base (4), so solving we have:

$4^{3}*4^{4}=4^{4+3}=4^{7}$

Hence, we have that the correct option is:

C) $4^{3}*4^{4}=4^{7}$

Have a nice day!
