A proposed change in income tax suggests charging 20% on a person's income up to $30,000 and then 40% on any

Answer:

If you get tax you should know the details of the what the tax is FOR

Step-by-step explanation:

Not enough details in question

Answer:

Step-by-step explanation:

Since the person earns over $30,000, they will be charged 20% on $30,000 plus 40% on ($47,000−$30,000)=$17,000. Hence the total amount of tax that they'd need to pay under the proposal is

Total Income Tax=$30,000×20%+$17,000×40%=$30,000×20100+$17,000×40100=$6,000+$6,800=$12,800.

|10-4x|-2=9
Please help

Answers

I'm assuming you're asking for x.

Answer: -1/4 and 21/4

Step 1: Add 2 to both sides of the equation.

∣10−4x∣=9+2

Step 2: You can get two equations from this.

10−4x=11  and -(10-4x)=11−(10−4x)=11

Solve both equations.

1st equation:

−4x=11−10

−4x=1

x=-1/4

2nd equation:

−10+4x=11

4x−10=11

4x=11+10

4x=21

x=21/4

Answer:

[tex]x=-\frac{1}{4} , \frac{21}{4}[/tex]

Step-by-step explanation:

Isolate the absolute value signs by adding 2 to both sides of the equation.

[tex]|10-4x|=11[/tex]

Create a positive and negative case to solve for absolute value problems.

[tex]10-4x=11 \\ 10-4x=-11[/tex]

Subtract 10 from both sides of both equations.

[tex]-4x=1 \\ -4x=-21[/tex]

Divide both sides of each equation by -4 in order to isolate and solve for x.

[tex]x=\frac{1}{-4} \\ x= \frac{-21}{-4}[/tex]

Simplify these x-values by canceling out the negative sign (2 negatives = 1 positive).

[tex]x= -\frac{1}{4} \\ x = \frac{21}{4}[/tex]

x = -1/4 and 21/4 are the solutions to this equation.

The base of a triangle exceeds the height by 5 yards. If the area is 250 square yards, find the length of the base and the height of the triangle

Answers

Answer:

height = 20 yards and base = 25 yards.

Step-by-step explanation:

let the height = x yards.

base = (5 + x) yards.

area = 250 square yards

Area = 1/2 bh

250 = 1/2 × (x)(5+x)

250 × 2 = 5x + x2

500 = x2 + 5x

x2 + 5x - 500 = 0

factorizing:

(x + 25)(x - 20) = 0

x = -25 or 20

but length cannot be negative,

hence x = 20 yards.

height = 20 yards

base = (5 + 20) = 25 yards.

Do you agree or disagree with the following statement? Explain your reasoning. "Since the speed of the ball is different at each position, there is no way to define probability density because I can’t calculate the probability at just one point."

Answers

Answer:

I disagree with the statement.

Step-by-step explanation:

Speed of the ball is different at each position:

This rhymes with the laws of physics because a ball placed at a certain height or on a certain slope will have a different speed (when thrown or rolled down) from a ball placed at a different height or on a different position on a plane.

There is no way to define probability density because i can't calculate the probability at just one point:

This statement is self-opposing as probability density is meant for times when probability value cannot be calculated or found for every given point! It is meant for continuous variables such as the one you're dealing with here - speed. The way to do this is to derive a probability density value for the variable in question (speed of the ball) for specific position intervals. Hence, divide the positions into intervals e.g.

A - B,   B - C,   C - D and so on.

So, probability density is used when you cannot the probability at just one point.

Kevin’s school is 5.2 miles away from his house. How far is this in yards? Do not round your answer. _________ yards

Answers

Answer :1,760 1,760 1,760 1,760 1,760

Answer:

The distance between Kevin's school and his house is 9,152 yards

Step-by-step explanation:

Units Conversion

Some common length units are meters, centimeters, inches, feet, miles, kilometers, and yards.

There are fixed numbers to convert one into another. For example:

1 mile = 1,760 yards

Since Kevin's school is 5.2 miles away from his house, that distance converted to yards is:

5.2 * 1,760 = 9,152

The distance between Kevin's school and his house is 9,152 yards

What are whole numbers?

Whole numbers is a set of numbers which consists of positive integers and zero. Fractions are not represented as whole numbers.

For ex: [0,1,2,3,4,5,6,7,8,9....] is a set of numbers without any negative number and fraction.

Given:

Divide 814 ÷ 3.7

Hence, we need to multiply a number to 3.7 in order to make it a whole number.

Step 1:

So multiply and divide by number 10

814 × 10 ÷3.7 × 10 = 37

Now we got the number 37 and 814 becomes 8140

Step 2:

We divide both the changed numbers:

8140 ÷ 37

Hence we get the quotient as 220
