Answer:

A 65.5%

Step-by-step explanation:

Percent decrease = (original - new)/ original * 100 percent

                              = (290-100)/290 * 100 %

                              = 190/290* 100%

                              =.655172414 * 100%

                               =65.5172414%

To the nearest tenth percent %

                                65.5%

4^3 = ?<br><br>A. 64<br>B. 7<br>C. 12<br>D. 1
Alexxandr [17]

By defining how exponents work, we conclude that 4^3 = 64, so the correct option is A.

<h3>How to find the cube of 4?</h3>

Let's remember how exponents work.

If we have a number a to the exponent n:

a^n

It means that we need to multiply the number a by itself n times.

Then, in this case:

4^3

Can be rewritten to.

4*4*4

Now we can solve that product:

4*4*4 = (4*4)*4 = 16*4 = 64

Then we conclude that the correct option is A

4^3 = 64

A house was purchased in 2005 for $150,000. It is now valued at $135,000. What is the percent of change for the house?
Ann [662]
22,500+135,00= 157,000
15% is wrong, 15% equals 22,500

Next, 10% 15000

If you add 15000 to 135000 it will equal 150000 so 10% is correct.
