If an investor has a $5,000 pretax return, the state tax rate is 4.5%, and the federal tax rate is 22.0%, what is the real investment value? $1,325 $3,675 $3,900 $4,775

Answers

Based on the given parameters, the real value of the investment is $3675

How to determine the value of the investment?

From the question, the given parameters about the investment are:

Pretax return = $5,000

State tax rate = 4.5%

Federal tax rate = 22.0%

The real value of the investment is calculated using the following formula

Real investment value = Pretax return - [(Pretax return * State tax rate) * Pretax return * Federal tax rate)]

Substitute the given values in the above equation.

Real investment value = 5000 - [(5000 * 4.5%) + (5000 * 22.0%)]

Evaluate the products

Real investment value = 5000 - [225 + 1100]

Evaluate the sum in the above equation

Real investment value = 5000 - 1325

Evaluate the difference in the above equation

Real investment value = 3675

Hence, the real value of the investment is $3675

3.142 * 7^2 = area of the whole circle

as we only have 1/4 of the circle we divide our area by 4

(3.142 *7^2) / 4 = 38.4895

Answer:

38.4895

Step-by-step explanation:

basically you are finding a quarter of the area of the circle. So the formula is 1/4πr^2

A state offers specialty license plates that contain 2 letters followed by 3 numbers. License plates are assigned randomly. All license plates are equally likely. Find the number of possible license plates that can be issued using this system

Answers

I am pretty positive the answer is 17,576

LLNNN, we contain 676000 combinations available for license plates.

How to estimate the number of possible license plates?

The number on license plates exists in the form LLNNN, where L denotes a letter and N denotes a number.

As L can be anything from A to Z, there exist 26 combinations for that and as repetition stands allowed, for second and third letters, we also contain 26 combinations available, and therefore 26 × 26 = 676 combinations for letters.

But numbers exist from 0 to 9 i.e. 10 combinations for each place and a total of 10 × 10 × 10 = 1000 combinations.

Therefore, LLNNN, we contain 676000 combinations available for license plates.

Can someone help me find the answer?

Answers

Answer: 16.2

Step-by-step explanation:

3x+11+ 8x+2=90

then subtract 3 on both sides (8-3) to equal 5x

then subtract 2 from 11

so you should have 9+5x= 90

subtract 9 from 90

so 5x=81 and then divide to get 16.2

Answer:

(3x+11) = 32 degrees

(8x+2) = 58 degrees

Step-by-step explanation:

The two expressions equal 90 degrees when added together, so we use this equation to find out their values:

(3x+11) + (8x+2) = 90
11x+13 = 90
11x+13-13 = 90-13
11x = 77
11x/11 = 77/11
x = 7

Now that we know x equals 7, we can factor it in both of the expressions to find their true values:

3x+11
3(7)+11
21+11
=  32 degrees

8x+2
8(7)+2
56+2
= 58 degrees

We know this is correct because both values equal to 90 degrees:

32 + 58 = 90

Liam's pumpkin will weigh more in week 10, and Patricia's pumpkin will weigh more in week 13. Then the correct option is C.

What is the linear system?

A Linear system is a system in which the degree of the variable in the equation is one. It may contain one, two, or more than two variables.

The table below shows the weights of Liam's pumpkin, l(w), and Patricia's pumpkin, p(w), over a four-week period which represents the number of weeks.

Liam's pumpkin grows at a constant rate.

Patricia's pumpkin grows at a weekly rate of approximately 52%.

Let x be the number of the week and y be the weight in pounds.

The equation of Liam's pumpkin will be

[tex]\rm y - 2.4 = \dfrac{5.5-2.4}{7-6} (x- 6)\\\\y - 2.4 = 3.1(x- 6)\\\\y = 3.1x - 16.2[/tex]

Then the weight of Liam's pumpkin after 10 weeks will be

y = 3.1 × 10 - 16.2

y = 31 - 16.2

y = 14.8

Then the weight of Liam's pumpkin after 10 weeks will be

y = 3.1 × 13 - 16.2

y = 40.3 - 16.2

y = 24.1

The equation of Patricia's pumpkin will be

[tex]\rm y = a\times (1.52)^{x}[/tex]

For x = 6 and y = 2.5

Then

[tex]\rm 2.5 = a \times 1.52^6\\\\a \ \ = 0.203[/tex]

We have

[tex]\rm y = 0.203 \times (1.52)^{x}[/tex]

Then the weight of Patricia's pumpkin after 10 weeks will be

[tex]\rm y = 0.203 \times (1.52)^{10}\\\\y = 13.36[/tex]

Then the weight of Patricia's pumpkin after 13 weeks will be

[tex]\rm y = 0.203 \times (1.52)^{13}\\\\y = 46.93[/tex]
