In Britain a Value Added Tax (VAT) of 17% is added to most purchases. If a skit costs $58.50 including tax, what is the price of the skirt before tax?

Answers

Answer:

i think it is  45.70

Step-by-step explanation:

Answer:

$48.55

Step-by-step explanation:

Make 17% into a decimal Multiply 0.17 and the number of Britain Value including tax Then take that number and subtract it by the number of Britain Value including tax

Equation:

17% = 0.17

Why? The symbol % is called the percent sign. The expression 17% means 17 parts out of 100. Therefore, 17% is equivalent to the common fraction and to the decimal fraction 0.17.

0.17 × (Britain Value Including Tax) 58.50 = 9.945 to be exact but I rounded it up to 9.95 for easier use

58.50 - 9.95 = 48.55

So $48.55 is your answer

I hope this helped! Brainliest highly appreciated! Tell me if this is wrong I would like to know :) All of this written and solved by me. Except for the italic explanation of how to make 17% a decimal. You are free to use this explanation if needed so don't feel hesitant to copy and paste this.

Liz flips a coin 90 times. The coin lands head up 63 times and tails up 27 times. The theoretical probability of the coin landing heads up is ___​%.

Answers

Answer:

50%

Step-by-step explanation:

This question asks for the theoretical probability

In order to find theoretical probability, we find how many outcomes are possible, and how likely each action is.

In this case, we are flipping a coin. There are only two possible outcomes of this, which are heads and tails. Each of these are equally likely, so that would mean the theoretical probability of flipping it and it landing heads up is 50%

Answer:

P(head up) = 70%

Explanation:

P(head up) = 63/90

P(head up) = 7/10

P(head up) = 70%

3. The mode it what number repeats ( -4)
4. The range is the subtracted greatest from the least (-1)
1. The mean is the average of those numbers. Add those numbers and divide it by how many numbers there are.
2. The median is the number in the middle. If there are two middle numbers, add those together and divide by two.
3. The mode is the number that repeats the most.
4. The range is the difference between the least and greatest number. Just take the greatest number and subtract it by the least number and you’ll have your answer.

Answer:50

Step-by-step explanation:

a right angle is always 90 degrees and we know triangles add to 180 degrees. So add 90 and 40 to get 130. Then subtract 180 from 130 to get 50.

50 because there can only be 1- 90 degrees angle in a triangle. A 180 angle is a strait line. You can go through a process of elimination

WHAT IS THE WORD CHOICE FOR THE FOLLOWING PARAGRAPHING___________________________________________________________________________________________________________________________________________In 1752, Benjamin Franklin had a theory that lightning was electricity. He wanted to prove that the power could be transferred to other objects. He grabbed a kite and experimented on a stormy afternoon.Franklin believed that thunder clouds contained electrical charges. His plan was to fly the kite into the clouds so that electricity passed down the wet kite string. With his son, William, as his assistant, he went to work.First, he tied an iron key to the silk kite string. Next, he ran a metal wire from the key into a jar designed to store electrical charges. Once the kite was in the air, he stood in a barn to keep safe and dry.Soon, electrical charges from the clouds passed into the kite. They traveled along the wet string, to the key, down the wire, and into the jar. When Franklin reached his hand toward the key, he received a mild shock. The electricity had been captured and transferred. The experiment was a success.At least it was for Benjamin Franklin. Other scientists were killed trying to duplicate his efforts. Looking back, it was not the safest way to test his theory. In this case, it worked out, and paved the way for future discoveries about electricity. "Poetry and music are very good friends.
