Put the decimal point to the right to make the divisor a full number if it isn't already. The dividend's decimal point should likewise be moved the same number of spaces to the right (adding some extra zeros if necessary.)

What is meant by decimal point?To distinguish between a full number and its fractional component, a decimal point is a point or a dot. A different name for it is Decimal Mark. The decimal point is the dot that appears in the middle of a whole number and its fractional component. Decimal numbers include, for instance, 34.5. 5 is the fractional portion in this situation, and 34 is a whole number. The decimal point is ".."The word decimal derives from the Latin decimus, which means tenth, from the base word decem, or 10.

If 25% of a number is 60 and 90% of the same number is 216, find 65% of that number.

Answers

65 percent of the number 240 is 156, as 25% and 90% of 240 will give 60 and 216 respectively.

How to calculate for the percentage

We shall represent the number with the letter x so that we evaluate for the 25 and 90 percent respectively as follows:

25 percent of x;

25x/100 = 60

x = (60 × 100)/25 {make x the subject}

x = 240

90 percent of x;

90x/100 = 216

x = (216 × 100)/90 {make x the subject}

x = 240

Find the sum and product of Eigen value of matrix A = 3 1 4 0 2 6 0 0 5

Answers

The sum of the eigenvalues of matrix A is 8 and the product of eigenvalues is -15.

What is the eigenvalue?

Eigenvalues are the special set of scalar values that are associated with the set of linear equations most probably in the matrix equations. The eigenvectors are also termed characteristic roots.

To find the eigenvalues of matrix A, we can solve the characteristic equation |A - λI| = 0, where λ is a scalar and I is the identity matrix.

|A - λI| = 3- λ 1 4 0 2- λ 6 0 0 5- λ

= (3-λ)(5-λ) - 24 = λ^2 - 8λ - 15

Setting λ^2 - 8λ - 15 = 0, we can find the eigenvalues of the matrix by solving the quadratic equation.

λ^2 - 8λ - 15 = 0

λ = (8 ± √(8^2 + 4*15))/2

λ = (8 ± √(64 + 60))/2

λ = (8 ± √124)/2

So the eigenvalues of matrix A are λ_1 = (8 + √124)/2 and λ_2 = (8 - √124)/2

The sum of eigenvalues is λ_1 + λ_2 = (8 + √124)/2 + (8 - √124)/2 = 8

The product of eigenvalues is λ_1 * λ_2 = (8 + √124)/2 * (8 - √124)/2 = -15

Hence, the sum of the eigenvalues of matrix A is 8 and the product of eigenvalues is -15.

Round your answer to three decimal places.

The jet plane emits ___ decibels at 8.1⋅102 watts per square meter.

Answers

149.0848502 decibels are emitted from a jet plane with a sound intensity of 8.1*10²

How to find the number of decibels?

Decibels are units for expressing the ratio between two physical quantities, usually amounts of acoustic or electric power, or for measuring the relative loudness of sounds.

Number of watts per square meter

d = 10*log(I/IO)

IO = 10⁻¹²

Therefore: d = 10 * log(I/10⁻¹²

jet plane has a sound intensity of 8.1*10² watts per square meter.

Therefore: d = 10*log((8.1*10²) / 10⁻¹²)

10²/10⁻¹² = 10²⁽⁻¹²⁾ = 10⁽²⁺¹²⁾ = 10¹⁴

Therefore: d = 10 * log(8.1 * 10¹⁴)

log(8.1 * 10¹⁴) = 14.90848502

10 * that = 149.0848502 decibels

A grandmother is now 48 years older than her grandson. 14 years ago she was thirteen times as old as her grandson. How old is the grandmother? How old is the grandson?

Answers

Let's call the grandmother's current age G and the grandson's current age S.

From the first piece of information given, we know that:

G = S + 48

From the second piece of information given, we know that:

G - 14 = 13S

We can use the first equation to substitute for G in the second equation:

(S + 48) - 14 = 13S

S + 34 = 13S

34 = 12S

S = 34/12

S = 2.8 years

So the grandson is 2.8 years old.

Now we can use this information to find the grandmother's age:

G = S + 48

G = 2.8 + 48

G = 50.8 years

So, the grandmother is 50.8 years old and the grandson is 2.8 years old.

(asked by point72)

Answers

I'm willing to pay up to $1 to play the game. If I get lucky and the coin lands on heads multiple times, I could potentially win more than $1.

The game is quite simple. I start with $1 and then flip a fair coin. If I get heads, I double my winnings and flip the coin again. I will keep flipping the coin until I get tails, at which point the game is over and I collect the money I have won. Depending on how lucky I get, I could potentially win more than $1. Therefore, I am willing to pay up to $1 to play the game. The expected value of this game is $1.50. This is because, on average, I will get heads 50% of the time and tails 50% of the time. So, if I get heads every time, I will double my winnings each time and end up with $2. If I get tails every time, I will end up with $1. Therefore, the expected value is the average of these two outcomes, which is $1.50. There is also some risk involved in this game. If I get unlucky and get tails on my first flip, then I will only get my money back and not make any profit. Therefore, I have to be willing to take on some risk if I want to try and make a profit. It is important to note that this game does not guarantee a profit. The expected value may be $1.50, but I could end up making less or more than that depending on how lucky I get. Therefore, I have to be willing to accept some uncertainty if I want to play this game.

The converse of the Pythagorean Theorem states that if two sides of a triangle are congruent, then the angles opposite to them are also congruent. This property is known as the Corresponding Angles Postulate.

The Pythagorean Theorem states that the sum of the squares of the lengths of the two sides of a right triangle are equal to the square of the length of the hypotenuse. The theorem is written as a^2 + b^2 = c^2. The converse of the Pythagorean Theorem states that if two sides of a triangle are congruent, then the angles opposite to them are also congruent. This property is known as the Corresponding Angles Postulate.  To prove this postulate, we can start with an arbitrary triangle ABC. If we extend the side AC to D, then we can create a line parallel to BC, creating two similar triangles, ABC and ADC. Since similar triangles have corresponding angles that are congruent, then  angle A = angle D. Since side AC is congruent to side AD, then angle A is also congruent to angle B.

%

Answers

The Lakewood Times had a 30.4% increase in the number of subscribers after it was bought out.

What is the percentage increase?

Percent increase is a way of measuring how much something has increased relative to its original value. It is expressed as a percentage, and it is calculated by taking the difference between the new value and the original value, and then dividing that difference by the original value, and then multiplying by 100.

Formula: % increase = (new value - original value) / original value x 100

To find the percent increase, you can use the formula:

% increase = (new value - old value) / old value x 100

In this case, the percent increase would be:

% increase = (6201 - 4770) / 4770 x 100 = 30.4%

do the following: a) find the real and imaginary parts, and sketch each with a stem plot. b) find the magnitude and phase, and sketch each with a stem plot. g

Answers

a) To find the real and imaginary parts of a complex number, we can use the equation z = x + iy, where x is the real part and y is the imaginary part.

To sketch a stem plot, we need to plot the real part on the x-axis, and the imaginary part on the y-axis. For example, for the complex number z = 4 + 3i, the real part is x = 4 and the imaginary part is y = 3. Therefore, the stem plot would be (4, 3).

b) To find the magnitude and phase of a complex number, we can use the equation z = |z|e^(iθ), where |z| is the magnitude and θ is the phase. To sketch a stem plot, we need to plot the magnitude on the x-axis, and the phase on the y-axis. For example, for the complex number z = 4 + 3i, the magnitude is |z| = 5 and the phase is θ = arctan(3/4). Therefore, the stem plot would be (5, arctan(3/4)).

To make 4 cups of punch, David needs 3 cups of cranberry juice. David wants to make 72 cups of punch.


How many cups of cranberry juice will he need?

Answers

Answer:   54 cups of cranberry juice

Work Shown:

4/3 = 72/x

4x = 3*72

4x = 216

x = 216/4

x = 54

Explanation:

Each fraction in the first step is of the form A/B, where A is the amount of punch and B is the amount of cranberry juice. Both measured in cups. In the 2nd step, I cross multiplied. Afterward, divide both sides by 4 to isolate x.

in a survey collecting data about the salaries earned by recent college graduates, li found that her salary was in the 78th percentile. that means that 78% of recent college graduates earn less than or equal to what li does. [1 point]

Answers

Li earns more than 78percentage of recent college graduates, and is in the 78th percentile of salaries earned.

1. Calculate the total number of recent college graduates surveyed: Multiply the total number of responses to the survey by 100 to get the total number of graduates surveyed.

2. Calculate the number of recent college graduates who earn less than or equal to Li's salary: Multiply the percentile (78%) by the total number of graduates surveyed to get the number of graduates who earn less than or equal to Li's salary.

3. Calculate the percentage of recent college graduates who earn less than or equal to Li's salary: Divide the number of graduates who earn less than or equal to Li's salary by the total number of graduates surveyed to get the percentage of graduates who earn less than or equal to Li's salary. The result will be 78%.
