PLEASE HELP AND TELL ME HOW YOU DID IT I HAVE TO SHOW work !! Jeans are on sale for 40% off the jeans Justin wants to buy them marked with an original price of 80 what is the total cost in dollars for a pair of jeans at the sale price including a 7% tax

Answers

Okay, if the jeans were originally $80, take 40% off of that (40% of 80 is 32) so you’d get 48. Now take 48 and multiply by 1.07 (to get 107% of the $48, to find a percentage you can move the decimal place left 2 digits and multiply), so Justin would pay $51.36 in total.

The area of a circle is 36 pi M squared what is the circumference in meters express your answer in terms of pi

Answers

Answer:

Circumference = 12π m

Step-by-step explanation:

The area of the circle, A = 36π

We need to find the circumference of the circle.

The area of a circle is given by :

[tex]A=\pi r^2\\\\36\pi=\pi r^2\\\\r=6\ m[/tex]

The circumference of a circle is given by :

[tex]C=2\pi r\\\\C=2\pi \times 6\\\\C=12\pi\ m[/tex]

So, the circumference of the circle is 12π meters.

You buy a flight to California for $305.72. The tax is 7.65%. What is the final cost of the ticket?



Show work and use method

Answers

Answer:309.83

Step-by-step explanation:

The final cost of the flight ticket $329.10758.

Given that, the cost of flight ticket is $305.72 and tax=7.65%.

What is the tax?

Taxes are mandatory contributions levied on individuals or corporations by a government entity—whether local, regional, or national. Tax revenues finance government activities, including public works and services such as roads and schools, or programs such as Social Security and Medicare.

Now, tax = 7.65% of 305.72

= 7.65/100 × 305.72

=0.0765 × 305.72

=$23.38758

Total cost = 305.72+23.38758

=$329.10758

Therefore, the final cost of the flight ticket $329.10758.

Write down 50-250 words of what the meaning of life is Could someone please help me out. All you have to do is write the following and take a picture of the righting and attach it. Please and thank you (It needs to be hand written and on any paper)I actually have been judged by the way I look plenty of times. I've had my fair shares of these experiences. People often have a tendency to observe a person once they meet someone new or in the event that they see a person in general and now and again people have a tendency to be inaccurate by these habits. It could also be as easy as your clothing, the manner you place your hands, the manner you speak etc. Although this stuff can inform lots approximately someone now and again it's just a character people tackle due to the fact all of us realize a person is judging them or they themselves are judging a person as well .One of my experiences are with teachers after I was in sixth grade I had a bad mind-set after I became told to be quiet when I spoke up and I became criticized for that, I in no way did my work nor listened to my teachers they thought I became a lost cause till I met a person who noticed I had capability she helped me through the year until now she helped me show all my teachers wrong that I could actually do something in my life. All I wanted was a bit of help and she helped me even though I might not have the high-quality grades I usually strive for, especially with work and all and but she continues to be right here supporting me that is certainly considered one among my experiences.In conclusion, no person should choose some other person due to the fact it is able to be a misjudgment or a easy mistake due to the fact now and again people have a small insignificant however it would not outline who they are everyone is unique so its higher to get to realize a person earlier than judging. Even in case you're judging a person as a minimum do not be negative and ensure your assumption is accurate. 1. What did the Battle of Gonzales mean to Mexico?Your answer:A. It was at war with Texas.
