Nadia made commission of $636 last week

She made $33072 commission in 2011.

In mathematics, a percentage is a number or ratio that can be expressed as a fraction of 100. If we have to calculate percent of a number, divide the number by the whole and multiply by 100. Hence, the percentage means, a part per hundred. The word per cent means per 100. It is represented by the symbol “%”.

Given,

Weekly commission of Nadia = 12%

Cost of stocks Nadia sold last week = $5300

Commission made by Nadia last week = 12% of $5300

                                                                 = (12/100) × 5300

                                                                 = 12 × 53

Commission made by Nadia last week = $636

No. of weeks in 2011 = 52 weeks

If she averages that same amount each week

Then commission made by her in 2011 = 52 × $636

                                                                 = $33072

Hence, $636 is the commission made by Nadia last week,

$33072 is the total commission made by Nadia in 2011.

[tex]d=\frac{|c_2-c_1|}{\sqrt{a^2+b^2}}[/tex]  is the formula used to calculate the distance between two parallel lines. This is derived from the slope-intercept equation.  

The two lines that never cross over one another are referred to as parallel lines. When the separation between these two lines is considered constant, then these two lines are parallel.

As a result, the distance between two lines can be determined by considering their perpendicular distance. The two parallel lines can be written using the slope-intercept form as y = mx + c₁ and y = mx + c₂, respectively.

Then, the formula to calculate distance is given by, [tex]d=\frac{|c_2-c_1|}{\sqrt{a^2+b^2}}[/tex]. Here, the intercepts of the two lines are c₁ and c₂, and a and b are the constants or integers.

The length of the hypotenuse of a 45 45 90 triangle with one side of length 8 is 8√2.

The length of the hypotenuse of a 45 45 90 triangle can be calculated using the Pythagorean Theorem. The Pythagorean Theorem states that the sum of the squares of the two sides of a right triangle is equal to the square of the hypotenuse. This can be expressed mathematically as a2 + b2 = c2, where a and b represent the lengths of the two sides and c represents the length of the hypotenuse.

In a 45 45 90 triangle, both sides are equal in length. This means that the mathematical equation simplifies to a2 + a2 = c2 or 2a2 = c2. To calculate the length of the hypotenuse, we can solve for c by taking the  square root of both sides, resulting in c = √2a.

In this particular example, if the length of one of the sides is 8, then the length of the hypotenuse can be calculated as c = √2(8) = 8√2. Therefore, the length of the hypotenuse of a 45 45 90 triangle with one side of length 8 is 8√2.

Two separate but related concepts are referred to as linear functions in mathematics: A polynomial function of degree 0 or 1 is referred to as a linear function in calculus and related fields if its graph is a straight line.

Here,

The points given on the scatterplot are (0,10),(4,42),(8,74) & (12,106)

By putting in the points in the given linear functions

y = 8 − 10x

y = 8 + 10x

In mathematics, the term "linear function" refers to two distinct but related ideas: In calculus and related subjects, a polynomial function of degree 0 or 1 is referred to as a linear function if its graph is a straight line.

Brad takes 6 minutes to run a mile assuming he can maintain the same pace.

Given that,

One lap around the inside lane of a standard track = 400m

Time taken for Brad to jog one lap around a track = 1 minute and 30 secs

We know that one mile = 1609.34 meters = 1600 meters (approximately)

Since Brad can jog 400m in 1 minute and 30 secs

1600 meters = 400*4 meters

Assuming that he can maintain the same pace:

so, the total time taken to run 1 mile = 1 minute 30 secs * 4 = 6 minutes

Hence, Brad takes 6 minutes to run a mile assuming he can maintain the same pace.

When a number greater than 1 is written in scientific notation, the exponent is positive.

Scientific notation is a way of expressing numbers that are very large or very small using a decimal number between 1 and 10, multiplied by a power of 10. For example, instead of writing the number 100,000,000 as 100,000,000, it can be written in scientific notation as 1 x 10^8.

The exponent of a number in scientific notation is the power of 10 that the decimal number is multiplied by, and it gives the number of places the decimal point is moved to the right or left to obtain the original number. In the example above, the exponent is 8, which indicates that the decimal point has been moved 8 places to the right to get the original number 100,000,000.

the square root 15v to the 4th power times square root of 2v to the 3rd power is 15v^2 x 2v^3, or 30v^5.

The square root of a number is a value that, when multiplied by itself, produces the original number. For example, the square root of 16 is 4 because 4 x 4 = 16. In mathematics, the square root of a number is written as a radical symbol, with the number inside the radical symbol. The square root symbol is also known as the radical symbol or radix.

What is the square root 15v to the 4th power times square root of 2v to the 3rd power?

Answer:

-2

Step-by-step explanation:

Let's call the unknown number x.

We are given that:

1/x + 15 = 13

To find the value of x, we need to isolate x on one side of the equation.

To do this, we can subtract 15 from both sides:

1/x + 15 - 15 = 13 - 15

This gives us:

1/x = -2

To find x, we can multiply both sides by x:

x * (1/x) = x * (-2)

This gives us:

x = -2x

Therefore the number is -2

The equation of variation is xy = k.

The required values are given below.

A proportional relationship is a relationship between two expressions and where changes in one expression means some constant change in the other expression as well. Generally, it is represented as x/y = k, where x and y are two expressions and k is constant.

Given:

y inversely varies as x.

That means, y ∝ 1/x.

So, y = kx, where k constant of variation.

Then, x × y = k

When y = 8, x = 3.

k = 3 × 8 = 24

So, the equation of variation is xy = 24.

When x = 6,

6y = 24

⇒ y = 4

When y = 9, x = 6.

k = 6 × 9 = 54

So, the equation of variation is xy = 54.

When y = 4,

4x = 54

⇒ x = 27/2

When y = 1.5, x = 14.

k = 1.5 × 14 = 21

So, the equation of variation is xy = 21.

When x = 9,

9y = 21

⇒ y = 7/3

When y = 20, x = 10.

k = 20 × 10 = 200

So, the equation of variation is xy = 200.
