Miki, a resident of Kyoto, earns an annual salary of ¥6,760,950. If the Japanese government levies a 29.12% income tax on Miki’s tax bracket, what is her yearly take-home pay, to the nearest whole yen?

Answers

Find 29.12% of 6,760,950. You can do this by converting 29.12% to a decimal by moving the decimal 2 places to the left and getting rid of the percent sign. Do this and you figure out 29.12% is .2912 as a decimal. Now you multiply this decimal with 6,760,950 to find what the government takes for taxes from his annual salary. You get 1,968,788.64. This is not your final answer because you want to find the amount of money he keeps after taxes. So you'd subtract 1,968,788.64 from 6,760,950. This gives you 4,792,161.36. This is his take-home pay, but you have to round to the nearest yen, so your final answer is 4,792,161.

Her yearly take-home pay, to the nearest whole yen is 4792161¥

What is percentage?

A value or ratio that may be stated as a fraction of 100 is referred to as a percentage in mathematics. If we need to compute a percentage of a number, we should divide it by its whole and then multiply it by 100. The proportion, therefore, refers to a component per hundred. Per 100 is what the term percent signifies. The letter "%" stands for it.

Given, Miki, a resident of Kyoto, earns an annual salary of ¥6,760,950.

Since,

the Japanese government levies a 29.12% income tax on Miki’s tax bracket

Thus,

tax she pays = 6,760,950 *29.12%

tax she pays =  6,760,950 *29.12/100

tax she pays =  1,968,788.64¥

remaining income to take home = total income - tax

remaining income to take home = 6,760,950 - 1,968,788.64

remaining income to take home = 4792161.36¥

Therefore, her yearly take-home pay, to the nearest whole yen is 4792161¥

How do u find the mean? I've never done this before the subject is try check and revise

Answers

Example you got

2,4,3,6,5

To find the mean you have to add those numbers

2+4+3+6+5 = 20

So you have to divide 5 by 20 because there are 5 number
20 divide 5 = 4

Mean equal 4

Answer,

The mean is the average of the numbers.  It's quite simple to find the mean. All you do is, add all the numbers togter & divide by how many numbers there are. In simpler words, it is the sum divided by the count.


For example,

The mean of the numbers is, 50

Explanation,

20 + 30 + 40 + 50 + 60 + 70 + 80 = 380

Then we divide 350 by how many numbers there are, 7. Then we get 50.

Luis skates 2/3 mile from his home to school. Isabella skates 2/4 mile to get to school. Who skates father?

Answers

In order to figure out whether Luis or Isabella skates farther to get to school, we have to create a common denominator between the two fractions that represent the distance that each person walks.

The least common denominator of 3 and 4 is 12.  This means that we have to change both fractions into equal fractions with denominators of 12.

To figure this out, we must set up a proportion.
2/3 = x/12
To solve this proportion, we must cross-multiply the fractions.  We get:
24 = 3x
If we divide both sides by the coefficient of x which is 3, to get the variable x alone, we get:
x = 8

Therefore, 2/3 = 8/12, so Luis skates 8/12 mile from his home to school.

If we do the same process for the 2/4 mile to get to school for Isabella, we get 6/12, because both fractions are equal to 1/2.

Therefore, we know that Luis skates 8/12 mile to school and Isabella skates 6/12 mile to get to school.  Because they have the same denominator, we can just compare the numerators.  We know that 8 is greater than 6, thus Luis skates farther to get to school.

Final answer:

Luis skates further to school than Isabella, as 2/3 mile is greater than Isabella's distance of 1/2 mile after simplification.

Explanation:

The question revolves around figuring out who skates further to school, Luis or Isabella. Luis skates 2/3 mile from his home to school whereas Isabella skates 2/4 mile (which can be simplified to 1/2 mile) to get to school. To determine who skates further, we look at the fraction representing the distance each person skates.

Luis's distance is 2/3 mile, and Isabella's distance, after simplification, is 1/2 mile. Since 2/3 is greater than 1/2, Luis skates further to get to school than Isabella.

Suppose that you have 4 shirts (red, green, blue, yellow) and 3 pairs of shoes (black, brown, red). If you choose your shirt and shoes randomly, what is the probability that your shirt and shoes will NOT be the same color?

Answers

There are 4*3 = 12 different outfits to pick. Imagine laying out a grid where you can list all of the possible choices for the outfit. Think of it like a multiplication table. It might be a handy way to visually sort everything out.

Of these 12 combos, only 1 has your shirt and shoes matching in color. This is when you pick the red shirt and red shoes. The other 12-1 = 11 outfits will not match.

The probability that you do not pick the same color shirt and shoes is 11/12 (exact fraction form) since there are 11 cases of nonmatching outfits out of 12 total. This is approximately equal to 0.9167 in decimal form which converts to 91.67%

(-0.5, 1.7)
(-0.1, 1.2)
(0.2, 1.5)

Answers

I believe it's the second one, (-0.5, 1.7)


Comment the correct answer. 

Answer:

(B)

Step-by-step explanation:

The given system of equations are:

[tex]y=x^2+3x+3[/tex]                                      (1)

and [tex]y=x^2+x+2[/tex]                                (2)

Subtracting equation (2) from (1), we get

[tex]0=2x+1[/tex]

⇒[tex]2x=-1[/tex]

⇒[tex]x={\frac{-1}{2}}[/tex]

⇒[tex]x=-0.5[/tex]

Now, substituting the value of x=-0.5 in equation (2), we get

[tex]y=0.25-0.5+2[/tex]

⇒[tex]y=1.7[/tex]

Thus, the values of x and y are -0.5 and 1.7.

Therefore, the approximate solution of the given system of the equation is (-0.5, 1.7).

Hence, option (B) is correct.

Now combine like terms

16 - 14 = w - 6w + 7w

2 = 2w

2w = 2

w = [tex] \frac{2}{2}  [/tex]

w = 1

Putri is searching for a secret cave that she knows is 3.72 kilometers from her home. Starting from her home, she walks 2.60 kilometers in a straight line before coming upon a large rock.
Climbing atop the rock, Putri spots the cave. She then turns 58 degrees to the right of her original path and walks to the cave. After exploring the cave, she looks back at the big rock and wonders how to get home.
Assuming Putri is facing the big rock, how many degrees to her left should she turn before walking home?

Answers

The Putri turned 36 degrees to her left should she turn before walking home if Putri is searching for a secret cave that she knows is 3.72 kilometers from her home. Starting from her home, she walks 2.60 kilometers in a straight line before coming upon a large rock.

What is the triangle?

The triangle can be defined as a three-sided polygon in geometry and it consists of three vertices and three edges. The sum of all the angles inside the triangle is 180°.

We have:

The total distance between cave to home AC = 3.72 km

The distance she walks AB = 2.60 km

The angle of turn = 58°

As we can see in the triangle ABC we can apply the sin law:

[tex]\rm \frac{AB}{sinx} = \frac{AC}{sin58\°}[/tex]

[tex]\rm \frac{2.6}{sinx} = \frac{3.72}{sin58\°}[/tex]

sinx = 0.5927

x = 36.35 ≈ 36°

Thus, the Putri turned 36 degrees to her left should she turn before walking home if Putri is searching for a secret cave that she knows is 3.72 kilometers from her home. Starting from her home, she walks 2.60 kilometers in a straight line before coming upon a large rock.

Putri should turn 122 degrees to her left when facing the big rock to head back to her home. This direction aligns her with the original path she took to reach the cave.

To determine the number of degrees to her left Putri should turn, we need to analyze her movements using the angles involved.

Putri starts by walking 2.60 kilometers in a straight line.She spots the cave after climbing the rock and turns 58 degrees to the right of her original path.This new path takes her directly to the cave, which is a straight-line distance of 3.72 kilometers from her home.

When Putri is in the cave facing the large rock, to get back to her home, she needs to turn in the opposite direction of her initial right turn:

Initially, she turned 58 degrees to the right.Facing the rock, she must turn 180 degrees - 58 degrees = 122 degrees to her left to be aligned with her starting path towards home.

Putri should turn 122 degrees to her left when facing the big rock to head back to her home.

A fourth degree polynomial with real coefficients can have -4, 8i,+4i, and as its zeros. True or false? Justify your answer.

Answers

You didn't give the fourth zero, but the answer is still false. If you have a root or an imaginary number as a zero, then its conjugate is also a zero. So if 8i is a zero, then -8i must also be a zero, and if 4i is a zero, then -4i must be a zero, with those zeros and -4, the number of zeroes exceeds the number of zeroes that a fourth degree polynomial can have.

The given statement is false, as a fourth degree polynomial with real coefficients -4, 8i,+4i cannot be formed it will form three degree or cubic polynomial as given by f(x) = (x + 4)(x - 8i)(x - 4i)

What is Polynomial ?

Polynomial is an expression that involves only the operations of addition, subtraction, multiplication, and non-negative integer exponentiation of variables.

Polynomials can be classified based on degree as linear, quadratic, cubic, fourth degree.

Let f(x) represent the function with zeros 4​, 8i ​, and 4i. Hence:

x = -4; 8i; x = 4i

x + 4 = 0; x - 8i = 0; x - 4i = 0

f(x) = (x + 4)(x - 8i)(x - 4i)

The three degree polynomial is given by f(x) = (x + 4)(x - 8i)(x - 4i)

To plot points on a number line without measuring, it needs to follow various points mentioned below.

What is a number line?

A number line is a visual representation of the real number system, where every point on the line corresponds to a unique real number.

Here,
To plot points on a number line without measuring, you can follow these steps:

Draw a number line with the lowest and highest values of the range you want to plot.Divide the number line into equal segments. The number of segments will depend on the range of the numbers and the precision required for the plot. For example, if you want to plot the numbers from 0 to 10 with a precision of 1 unit, you can divide the number line into 11 equal segments.Label each segment with the corresponding value of the number line. For example, if you divide the number line from 0 to 10 into 11 equal segments, label each segment with the numbers from 0 to 10 in increments of 1 unit.Locate the point you want to plot on the number line. For example, if you want to plot point 4, locate the segment labeled "4".Mark the point on the number line by drawing a small dot or an "X" at the corresponding location.

Repeat steps 4 and 5 for all the points you want to plot on the number line.

Hey there! :D

For this, you will need to draw your own diagram, but I think you can do this if I explain it. It should look like a triangle. Where the string is a vertex, and the kite is an upper vertex. The bottom is the distance. Look at the example. You can label the distances on it if you want to. 

c= length of the string (75m)

b= height of the kite (62m)

a will equal the distance between Janet and the spot on the ground beneath the kite. 

Now, we plug it into the Pythagorean theorem.

a^2+b^2= c^2

a^2+ 62^2= 75^2

Square the numbers.

a^2+3844= 5625

Subtract 3844 on both sides. 

a^2= 1781

Find the square root.
