3^6 over 3^? = 3^4

What is the missing value?

Answers

Answer 1
Answer: For the question mark, we can insert a variable considering it is an unknown number.

(3^6)/(3^x) = 3^4 \n \n 3^(6-x) = 3^4 \ / \ use \ qotient \ rule \n \n 6 - x = 4 \ / \ cancel \ out \ 3 \n \n -x = 4 - 6 \ / \ subtract \ 6 \ from \ each \ side \n \n -x = -2 \ / \ simplify \n \n x = 2 \ / \ multiply \ each \ side \ by \ -1 \n \n Answer: \fbox {x = 2}

Answer:

A pair of Nike Air Jordan sneakers cost $139.99.

There is a 35% off sale going on at Foot Locker.

=> Sale price = 139.99 - 139.99 x 35/100 = ~$90.99

Sales tax is 8.125% in Orange County.

=> The tax = 90.99 x 8.125/100 = ~$7.39

The total price is calculated by:

P = The sale price + The tax = 90.99 + 7.39 = ~$98.38

Hope this helps!

:)

Answer: Sale price before tax $90.99

Tax $7.39

Total after tax $98.38

Step-by-step explanation:

Sale price 139.99 x 0.65 = 90.99

Tax 90.99 x 8.125/100 = 7.39

Total 90.99 + 7.39 = 98.38

Tomaz realized that the tip of a second hand on a clock rotates about the center of the clock. He watched the second hand rotate around the center of the clock for 15 seconds. Which describes the rotation he observed? 270 clockwise rotation
90 clockwise rotation
180 rotation
90 counterclockwise rotation

Answers

Second hand on a clock rotates at rate 360 degrees per 60 seconds.

360 degrees - 60 sec
x degrees - 15 sec

x=(15\cdot360)/(60)\nx=15\cdot6\nx=90

90 clockwise rotation (none hand of a clock rotates counter-clockwise :))

In this exercise we will use the knowledge of rotation and find that the necessary rotation is 90 clockwise rotation.

To make the rotation calculations we will have to perform a rule of 3 where we will have the clock seconds and the angle formed by the hand, this can be described as:

360 \ degrees \rightarrow 60 sec\nx \ degree \rightarrow 15 sec

When performing this rule of 3 we will find 90 clockwise rotation
