Answer: B. 24 - 24 x r = 4.32

Step-by-step explanation:

The percent tip can be found by using the formula: tip = bill x (tip percentage in decimal form)

In this case, Diego's bill was $24 and the tip he paid was $4.32. To find the tip percentage, we can divide the tip by the bill:

tip / bill = 4.32 / 24 = 0.18

To convert the decimal to a percentage, we can multiply the decimal by 100: 0.18 x 100 = 18%

The tip percentage is 18%

So, option B. 24 - 24 x r = 4.32 is the equation that will help find the percent tip that Diego gave the server.

To calculate the state income tax owed on a $50,000 per year salary, we need to apply the progressive tax rate based on the income range.

What does money interest mean?

You pay interest on any loans or borrowings of money. the portion of the loan's value that lenders use to calculate interest. Consumers can earn interest by lending money (via a bond or certificate of deposit, for example), or by putting money into an interest-bearing bank account.

The first $10,000 of the salary will be taxed at 3%, the next $40,000 (from $10,001 to $50,000) will be taxed at 5%, and the remaining $0 will be taxed at 5.5%

Tax on first $10,000 = $10,000 x 3% = $300

Tax on next $40,000 = $40,000 x 5% = $2,000

Tax on remaining $0 = $0 x 5.5% = $0

Total tax owed = $300 + $2,000 + $0 = $2,300

Therefore, the state income tax owed on a $50,000 per year salary is $2,300.

Given: cost of CAYMAN sleep couch with VAT is R2 699

cost without VAT is R1 999

2.1  To calculate the original price of the couch excluding VAT, we can use the following formula:

Price including VAT / 1 + (VAT rate / 100) = Price excluding VAT

In this case, the VAT rate is 15% (since it is included in the original price), so the formula is:

R2,699 / 1 + (15 / 100) = R2,346.96

2.2  To calculate the expected price of the couch including VAT at the sale price, we can use the following formula:

Price excluding VAT * (1 + (VAT rate / 100)) = Price including VAT

In this case, the VAT rate is still 15% and the sale price is R1,999 (excluding VAT), so the formula is:

R1,999 * (1 + (15 / 100)) = R2,299

The errors on scale 1 and scale 2 are 15% and 6%.

This talks about how correct a scale is over a time.

The amount of something is expressed as if it is a part of the total which is a hundred. The ratio can be expressed as a fraction of 100. The word percent means per 100. It is represented by the symbol ‘%’.

Scale 1, measured weight = 85, and actual weight = 100.

Scale 2, measured weight = 47, and actual weight = 50.

Error % is given by the formula,

(Actual value - Measured value)/Actual value * 100/1

For scale 1

Measured weight = 85, and actual weight = 100.

Percentage error =(Actual value - Measured value)/Actual value * 100/1

Percentage error = (100-83)/100

Percentage error = 15%

For scale 2

Measured weight = 47, and actual weight = 50.

Measured value)/Actual value * 100/1

Percentage error = (50-47)/50

Percentage error = 6%

Thus the error in scale 1 and scale 2 is 15% and 6%. respectively

The population of the  River City expanded by 10% between 2000 and 2010, and it is anticipated to grow by 8% between 2010 and 2020.

A number or ratio that is expressed as a fraction of 100 is known as a percentage in mathematics. There are also sporadic uses of the acronyms "pct.," "pct," and "pc." However, the percent sign "%" is widely used to signify it. There are no dimensions to the percentage amount. Percentages are essentially fractions because they have a numerator of 100. Put the percent sign (%) next to a number to indicate that it is a percentage. For instance, you would score a 75% if you answered 75 out of 100 questions on a test correctly (75/100). Divide the money by the total to get percentages, then multiply the result by 100. The formula (value/total) x 100% is used to determine the percentage.

Therefore, the ratio of 5:2 is the p:q ratio of 2p=5q. When two quantities are proportionate, one rises and the other follows suit.

Relationships that have the same ratio over time are said to be proportional. For instance, how many trees there are in an orchard and how many apples there are in a harvest of apples are determined by the average number of apples per tree. Proportional in mathematics refers to a linear relationship between two numbers or variables. When the first quantity doubles, so does the other. When one of the variables drops to 1/100th of its previous value, the other also decreases. When two quantities are proportional, it means that when one rises, the other rises as well, and the ratio between the two quantities stays the same at all values.

[tex]\dfrac{1}{2a}t \ \text{sin} \ \text{at}[/tex] is the solution of (18s)/(s²+36)²​ using convolution property.

Convolution is a mathematical operation on two functions (f and g) that results in a third function (f×g) that expresses how the shape of one is altered by the other. It is a mathematical operation on two functions (f and g) in mathematics, more specifically in functional analysis.

Convolution is a term that describes both the method of computing a function and its result. Its definition states that it is the integral of the product of the two functions after one of them has been shifted and reflected about the y-axis. The result of the integral remains unchanged regardless of which function is chosen to be reflected and shifted before it (see commutativity). The convolution function is created by evaluating the integral across all shift values.

[tex]\begin{aligned}& =\frac{1}{a} \int_0^t \cos a u \sin a(\mathrm{t}-\mathrm{u}) \mathrm{du} \\& =\frac{1}{a} \int_0^t[\cos a u \sin (a \mathrm{t}-a u)] \mathrm{du} \\& =\frac{1}{a} \int_0^t\left[\frac{\sin (a \mathrm{t}-a u+a u)+\sin (a \mathrm{t}-a u-a u)}{2}\right] \mathrm{du} \\& =\frac{1}{2 a} \int_0^t[\sin (a \mathrm{t})+\sin a(\mathrm{t}-2 u)] \mathrm{du} \\& =\frac{1}{2 a} \int_0^t[\sin (a \mathrm{t})+\sin a(\mathrm{t}-2 u)] \mathrm{du} \\\end{aligned}[/tex]

Answer: The expression is (22) +12/(22) = 4 + 12/4 = 4 + 3 = 7.

Step-by-step explanation:

To evaluate the expression 2w+12 ÷ (2x) for w=2 and x=2, we need to substitute the given values into the expression and simplify.

First, we substitute the value of w=2 into the expression, giving us 2(2)+12 ÷ (2x).

Next, we simplify the expression by multiplying 2 and 2, getting 4+12 ÷ (2x).

Then we add 4 and 12, getting 16 ÷ (2x).

Finally, we substitute the value of x=2 into the expression, giving us 16 ÷ (2(2)) = 16 ÷ 4 = 4.

So the final value of the expression 2w+12 ÷ (2x) for w=2 and x=2 is 4.
