Dennis Hausearns $67,000 per year as a business manager. His exemptions
include himself, his wife, and their daughter. The state tax rate in his state is
3.5% of taxable income. Find the state tax withheld using the following figure.
Exemptions
Single
$1,500
Married $3,000
Each Dependent $1,500
$2,142.32
$2,361.50
$2,187.50
$2,237.50

Answers

Answer: $2,187.50

Step-by-step explanation:

Define all the exemptions that applie:

exemption for being married: $3000

exemption for 1 dependent: $ 1,500

3000 + 1500 = 4500

Subtract the exemptions from the yearly earnings:

67000 - 4500 = 62,500

Now, applied the 3.5 % tax

3.5 / 100 = (0.035)

62,500 x 0.035 = 2187.50

A spinner has 4 equal sectors colored yellow, blue, green, and red. If in 100 spins we get
28 blue (B), 25 red (R), 29 green (G), and 18 yellow (Y) outcomes, find the empirical probability of getting color P(R).
O A. 6/25
OB. 1/4
O C. 3/10
O D. 13/50

Answers

Answer:

Step-by-step explanation:

28+25+29+18 = 100

red = 25

25/100 = 1/4

The required empirical probability is 1/4 which gets the color of red P(R).

What is probability?

The probability is defined as the possibility of an event being equal to the ratio of the number of favorable outcomes and the total number of outcomes.

A spinner has 4 equal sectors colored yellow, blue, green, and red. If in 100 spins we get

28 blue (B), 25 red (R), 29 green (G), and 18 yellow (Y) outcomes

To find the empirical probability of getting a red outcome, we need to divide the number of red outcomes by the total number of spins:

P(R) = 25 red outcomes / 100 spins

Apply the division operation, and we get

P(R) = 1/4

Hence, the required empirical probability is 1/4

Therefore, the correct answer is 1/4 or option B.

62 points! a bus traveled on a level road for 3 hours at an average speed of 20 miles per hour faster than it traveled on a winding road. The time spent on the winding road was 6 hours. Find the average speed on the levelroad if the entire trip was 482 miles.

Answers

Answer:

≈ 66.89 mph

Step-by-step explanation:

Let the average speed on the level road was x.

Then the average speed on the winding road was x - 20.

The total distance is:

3x+ 6(x - 20) = 4823x + 6x - 120 = 4829x = 482 + 1209x = 602x = 602/9x ≈ 66.89 mph

Howard's stew recipe makes 6 servings and uses 2 carrots and 3 ears of corn. Drag carrots and corn into the box to show how many Howard needs for 12 servings.

Answers

Answer: 4 carrots and 6 ears of corns

Step-by-step explanation:

Howard needs 4 carrots and 6 ears of corn for 12 servings of stew.

How many carrots and ears of corn does Howard need for 12 servings of stew?

To get how many carrots and ears of corn Howard needs for 12 servings of stew, we can set up a proportion based on the number of servings.

Let x be the number of carrots

Let y be the number of ears of corn needed for 12 servings.

Proportion:

6 servings of stew need 2 carrots and 3 ears of corn

12 servings of stew need x carrots and y ears of corn

(2 carrots) / (6 servings) = (x carrots) / (12 servings)

(3 ears of corn) / (6 servings) = (y ears of corn) / (12 servings)

2 * 12 = 6 * x

3 * 12 = 6 * y

24 = 6x

36 = 6y

Solve for x and y:

x = 24 / 6

x = 4

y = 36 / 6

y = 6.

Let x be the last digit in your Student number. Give x?
A principal of $350x is invested at 8 % interest for 5 years. Determine the future value
if the interest is compounded quarterly .

Answers

After being compounded for a period of 5 years, the amount will rise to $5,200.82.

The interest is given on an annual basis and so is the period yet the compounding period is quarterly. The first thing to do therefore, is to convert the interest and period to quarterly measures.

Interest = 8% / 4 = 2% per quarter

Periods = 5 x 4 = 20 quarters

Amount will be $3,500

The amount after 5 years will be:

= Amount x ( 1 + rate) ^ number of periods

= 3,500 x ( 1 + 2%) ²⁰

= $5,200.8158859

= $5,200.82

In conclusion, the amount will be $5,200.82 after 5 years.

Is 8 a solution to the equation x+6=x+6

Answers

Answer:

If you mean could x be eight, then yes, x could equal eight. However, any number could be the solution as this equation has an infinite solution.

Step-by-step explanation:

Once again, I am going off of you are asking if eight could be x. If that is what you are asking, here is the reason.

The equal sign shows that both sides equal each other. If you plug in 8 for x, then you get:

8+6=8+6

14=14

Does 14=14? Yes, so plugging in eight for x works. However, looking at this, we can see that your solution would actually be an infinite solution. This is because, no matter what number we plug in for x, we will get a true statement.

A missile uses an internal computer clock to measure time in tenths of a second. The missile guidance system needs the time from launch, in seconds, in order to calculate its distance from the launch site. It obtains this by multiplying the computer clock time by 0.1. So, for example, a reading of 50 tenths of a second is 5 seconds. For one particular missile system, the conversion factor of 0.1 is stored in 8 bits as the binary number 0.000110012.

The missile’s internal computer clock shows 200 tenths of a second. Convert this to seconds using your result from Part (i) of this question. Do not round your answer. The missile guidance system now records that it has travelled for this number of seconds.

Answers

Using proportions, it is found that the missile's internal computer clock is of 20 seconds.

According to the information given, this question can be solved by proportions, using a rule of three.

50 tenths of a second is equivalent to 5 seconds, and we want to find the equivalent to 200 tenths of a second, thus, the rule of three is:

50 tenths - 5 seconds

200 tenths - x seconds

Applying cross multiplication:

[tex]50x = 5(200)[/tex]

[tex]50x = 1000[/tex]

[tex]x = \frac{1000}{50}[/tex]

[tex]x = 20[/tex]

The missile's internal computer clock is of 20 seconds.
