Calculate sales tax using the following information:
Taxable amount of the sale: $150
Sales tax percentage: 7%
What is the amount of the sales tax?
Round the answer to the nearest cent (hundredths).

Answers

A percentage is a way to describe a part of a whole. The amount of the sales tax is $10.5.

What are Percentages?

A percentage is a way to describe a part of a whole. such as the fraction ¼ can be described as 0.25 which is equal to 25%.

To convert a fraction to a percentage, convert the fraction to decimal form and then multiply by 100 with the '%' symbol.

Given the taxable amount of the sale is $150, while the Sales tax percentage is 7%. Therefore, the amount of sales tax is,

Amount of sales tax = 7% of $150 = 0.07 × 150 = $10.5

Hence, the amount of the sales tax is $10.5.

Shirts are 50% off. The original price of one shirt is $60. dollars, of two shirts, at the sale price, including a 10% sales tax​

Answers

Answer:

I guess, you are asking how much two shirts are costing now.

the answer is $66

Step-by-step explanation:

sales tax is always calculated from the actual sales price (and never from a list price or so).

so, the discount is 50%.

=> a shirt now costs only $30 (instead of $60).

50/100*60 = $30

now, sales tax is calculated from these $30.

=> 10% of $30 is $3

10/100*30 = $3

therefore, a single shirt costs now $30+$3 = $33 incl. sales tax.

two shirts cost therefore 2 * $33 = $66

Answers

Answer:

Volume of box is 288 in^3

Step-by-step explanation:

12 inches x 8 inches x 3 inches works out to

12*8*3 in^3, or 288 in^3.  This capacity is just too small to accommodate 312 in^3 of cereal.

Can somebody please help in this question?

Answers

First find the area of one side.

The area of the side of a cube is s^2 where s is the length if one edge.

The edge length is given as 2/3, so the area of a side is 2/3^2 which is equal to 2/3 x 2/3 = 4/9 square units.

A cube has 6 sides so now to find the surface area of the cube multiply the area of one side by 6 sides:

4/9 square units x 6 = (4 x6)/9 = 24/9 which can be rewritten as 2 2/3 square units

The answer is 2 2/3 units^2

Peter was in a line. There were twice as many students in front of him as behind him. Students (more than 3 but fewer than 9) left the line but Peter did not. Then twice as many students were behind Peter as in front. How many students left the line?

Answers

Answer:

6 people left

Step-by-step explanation:

4 behind him 8 infront 6 left from infront leaving 4 behind 2 infront

Answer:

6 students

Explanation:

x = the number of students in front of peter

y = the number of students behind peter

z = the number of students who left, for 3 < z < 9 ∴ z ∈ {4, 8}

system of equations:

x = 2y2(x-z) = y (assuming that the students who left were all among the students who are in front of peter)

x = 2y ⇒ y = x/2 (defining y with x)

2(x-z) = y (lets substitute y)

2(x-z) = x/2

2x-2z = x/2

2(2x-2z) = x

4x-4z = x

4x-x = 4z

3x = 4z

if z = 6 (i pluged the numbers from 4 to 8)

then

3x = 4×6

3x = 24

x = 24/3

x = 8

∴ y = 4

8 students were in front of peter and 4 were behind him

6 left

now 2 students are in front of peter and 4 are behind him

8 is twice 4

8-6 = 2

4 is twice 2

In an early home game, an NBA team made 70.21 percent of their 94 free throw attempts. In one of their last home games, the team had a free throw percentage equal to 76.4 percent out of 89 attempts. Did the team significantly improve its free throw percentage

Answers

Answer:

The team scored more free throws in fewer attempts (68 versus 66) and, furthermore, if the same amount of free throws had been attempted, the number of hits with that percentage would be 72. Therefore , it can be stated that the team significantly improved its free throw percentage.

Step-by-step explanation:

Given that in an early home game, an NBA team made 70.21 percent of their 94 free throw attempts, and in one of their last home games, the team had a free throw percentage equal to 76.4 percent out of 89 attempts, to determine if the team significantly improved its free throw percentage, the following calculation must be performed:

100 = 94

70.21 = X

70.21 x 94/100 = X

66 = X

100 = 89

76.4 = X

76.4 x 89/100 = X

68 = X

100 = 94

76.4 = X

76.4 x 94/100 = X

72 = X

Therefore, at first glance, the team scored more free throws in fewer attempts (68 versus 66) and, furthermore, if the same amount of free throws had been attempted, the number of hits with that percentage would be 72. Therefore , it can be stated that the team significantly improved its free throw percentage.

You will choose to write either a narrative essay or an informational response paragraph.The Railway ChildrenBy Edith NesbitChapter I, The Beginning of ThingsThey were not railway children to begin with. I don't suppose they had ever thought about railways except as a means of getting to Maskelyne and Cook's, the Pantomime, Zoological Gardens, and Madame Tussaud's. They were just ordinary suburban children, and they lived with their Father and Mother in an ordinary red-brick-fronted villa, with coloured glass in the front door, a tiled passage that was called a hall, a bath-room with hot and cold water, electric bells, French windows, and a good deal of white paint, and 'every modern convenience', as the house-agents say.There were three of them. Roberta was the eldest. Of course, Mothers never have favourites, but if their Mother HAD had a favourite, it might have been Roberta. Next came Peter, who wished to be an Engineer when he grew up; and the youngest was Phyllis, who meant extremely well.Mother did not spend all her time in paying dull calls to dull ladies, and sitting dully at home waiting for dull ladies to pay calls to her. She was almost always there, ready to play with the children, and read to them, and help them to do their home-lessons. Besides this she used to write stories for them while they were at school, and read them aloud after tea, and she always made up funny pieces of poetry for their birthdays and for other great occasions, such as the christening of the new kittens, or the refurnishing of the doll's house, or the time when they were getting over the mumps.These three lucky children always had everything they needed: pretty clothes, good fires, a lovely nursery with heaps of toys, and a Mother Goose wall-paper. They had a kind and merry nursemaid, and a dog who was called James, and who was their very own. They also had a Father who was just perfectnever cross, never unjust, and always ready for a gameat least, if at any time he was NOT ready, he always had an excellent reason for it, and explained the reason to the children so interestingly and funnily that they felt sure he couldn't help himself.You will think that they ought to have been very happy. And so they were, but they did not know HOW happy till the pretty life in the Red Villa was over and done with, and they had to live a very different life indeed.The dreadful change came quite suddenly.------------------------Select only one prompt.
