Find the total amount given the original price and tip rate. Round to the nearest cent if necessary. Original price: $41.32 Tip: 15%

Answers

Answer:

$6.20

Step-by-step explanation:

We can covert 15% to a decimal by moving the decimal point two places over.

15% = 0.15

41.32 X 0.15 = 6.198

6.198 ≈ $6.20

The percentage is calculated by dividing the required value by the total value and multiplying by 100.

Original price: $41.32

Tip: 15% = %6.189

Total amount = = Original price + Tip amount

The total amount is $47.509

What is a percentage?

The percentage is calculated by dividing the required value by the total value and multiplying by 100.

Example:

Required percentage value = a

total value = b

Percentage = a/b x 100

Example:

50% = 50/100 = 1/2

25% = 25/100 = 1/4

20% = 20/100 = 1/5

10% = 10/100 = 1/10

We have,

Original price: $41.32

Tip: 15%

Now,

The amount of the tip.

= 15% of 41.32

= 15/100 x 41.32

= $6.189

The total amount.

= Original price + Tip amount

= 41.32 + 6.189

= $47.509

Thus,

Original price: $41.32

Tip: 15% = %6.189

Total amount = = Original price + Tip amount

The total amount is $47.509

Answers

Answer:

The area of the composite shape is:

122.50 [tex]cm^{2}[/tex]

Step-by-step explanation:

To find the area of composite shapes you can pull apart this in known shapes, in this case, a rectangle and a triangle. Taking into account this, we can find the rectangle area firstly:

Rectangle area = base * height

The base of the rectangle is the measure from down (14 cm) and the height is the measure in the left side (7 cm), with these values we can replace the formula:

Rectangle area = base * heightRectangle area = 14 cm * 7 cmRectangle area = 98 [tex]cm^{2}[/tex]

Now, to calculate the area of the remaining triangle, we must use the next formula:

Triangle area = [tex]\frac{base*height}{2}[/tex]

Where the base would be equal to the left side of the shape (7 cm) and the height is the difference between the measurement in the top side and the measurement in the bottom side:

Height of the triangle = top side - bottom sideHeight of the triangle = 21 cm - 14 cmHeight of the triangle = 7 cm

We can replace in the formula:

Triangle area = [tex]\frac{7 cm * 7cm}{2}[/tex]Triangle area =[tex]\frac{49cm^{2} }{2}[/tex]Triangle area = 24.5 [tex]cm^{2}[/tex]

By last, we must add the two values of the areas obtained:

Area of the composite shape = rectangle area + triangle area.Area of the composite shape = 98 [tex]cm^{2}[/tex] + 24.5 [tex]cm^{2}[/tex]Area of the composite shape = 122.5 [tex]cm^{2}[/tex]

What is Percentage?

To determine the quantity or percentage of something in terms of 100, use the percentage formula. Per cent simply means one in a hundred. Using the percentage formula, a number between 0 and 1 can be expressed. A number that is expressed as a fraction of 100 is what it is. It is mostly used to compare and determine ratios and is represented by the symbol %.

Given:

Total students= 900

Percent of student who walk to school= 30%

So, the number of students walk to school on Monday

= 30% of 900

= 30/100 x 900

= 30 x 9

= 270

Hence, 270 students walk to school on Monday.

You are paying off a student loan in monthly installments. After
the 4rd payment the remaining balance is $13,900. After the 5th
payment your remaining balance is $13,500. If n is the number of
payments that have been made, what is the nth term rule?

Answers

Answer:

The loan will be paid after 39 monthly installments.

Step-by-step explanation:

Since I am paying off a student loan in monthly installments, and after the 4th payment the remaining balance is $ 13,900, while after the 5th payment my remaining balance is $ 13,500, to determine the amount of payments in which the loan was agreed I must perform the following calculation:

13900 - 13500 = 400

400 x 5 = 2000

2000 + 13500 = 15500

15500/400 = 38.75

Thus, the loan will be paid after 39 monthly installments.
