Answer:

\(\frac{10}{21}\)

Step-by-step explanation:

The LCM of 14, 21 and 6 is 42

We require to change the fractions to fractions with a denominator of 42

\(\frac{3(3)}{14(3)}\) + \(\frac{2(2)}{21(2)}\) + \(\frac{1(7)}{6(7)}\)

= \(\frac{9}{42}\) + \(\frac{4}{42}\) + \(\frac{7}{42}\) ← add the numerators, leaving the denominator

= \(\frac{9+4+7}{42}\)

= \(\frac{20}{42}\) ← divide both values by 2

= \(\frac{10}{21}\) ← in simplest form

Answer:

  B.  (3, 17)

Step-by-step explanation:

You want to solve this system of equations by substitution:

We are given an expression for y. Substituting that into the first equation gives ...

  x + (3x +8) = 20

  4x = 12 . . . . . subtract 8

  x = 3 . . . . . . divide by 4

  y = 3(3) +8 = 17

The solution is (x, y) = (3, 17).

If Deja's grandparents are paying for 80% (percentage) of her first year's expenses, the amount that Deja needs to pay for is $3,560.40.

The amount that Deja needs to pay is computed as the difference between 100% of the total expenses and 80%.

The percentage refers to the ratio of one value, quantity, or number compared to another.

Tuition & Fees = $8,232

Housing Books = $6,540

Supplies = $1,130

Transportation = $1,900

Total expenses = $17,802

80% of first year's expenses = $14,241.60 ($17,802 x 80%)

20% (100% - 20%) of the expenses = $3,560.40 ($17,802 x 20%)

Answer:

$0.56, or 56¢.

Step-by-step explanation:

According to the picture, there are two dimes, two nickels, a penny, and a quarter.

A penny is worth $0.01.

A nickel is worth $0.05.

A dime is worth $0.10.

A quarter is worth $0.25.

2(0.1) + 2(0.05) + (0.01) + (0.25) = 0.2 + 0.1 + 0.01 + 0.25 = 0.3 + 0.26 = 0.56.

So, Vivian is using $0.56, or 56¢, to buy a toy. That's a cheap one!

Hi! To find the primitive function of 4x, you need to determine the antiderivative of the given function.

The primitive function of 4x is:

∫(4x) dx = 4∫(x) dx = 4(x^2/2) + C

So the primitive function of 4x is \(2x^2 + C\), where C is the constant of integration.

You're right, 20 is correct

20 x 20 x 20, aka \(20^3\) = 8000,

From the given results, we found that the relative frequency of rolling a 3 is 9/40.

What is the relative frequency?

The relative frequency is calculated as the ratio of the number of occurrences of a given value of the data in the set of all outcomes to the total number of outcomes. Frequency is a measure of how frequently an event happens. While not a theoretical concept, relative frequency is one that is currently being tested. The fact that it is experimental means that if we repeat the trials, we might get different relative frequencies. In order to compare the frequency of a specific event to all other occurrences, relative frequency is used.

The complete question is given below.

Number of times Danielle rolled a number cube = 40

We are asked to find the relative frequency of rolling a 3.

Relative frequency = frequency/ Total frequency

From the table,

Frequency of 3 = 9

Total frequency = 5 + 5+ 9 + 6 + 7 + 8 = 40

Then the relative frequency of 3 = 9/40

Therefore from the given results, we found that the relative frequency of rolling a 3 is 9/40.

The equivalent ratios to tan F = EL/ EF = OS/OJ

Similar triangles are those with the same shape but different sizes. Similar triangles include all equilateral triangles and squares with any side length.

All related pairs of angles will be equal and corresponding sides of similar triangles will have the same ratio. The symbol '∼' is used to represent the similarity.

Given that

△FEL∼△JOS

That means △FEL and △JOS are similar triangles

As we know tan θ = Opposite side / Adjacent side

From the triangle △FEL,

=> tan F = EL/EF

To calculate the derivative matrix of the spherical coordinate transformation T, we need to find the partial derivatives of x, y, and z with respect to rho, phi, and theta.

Let's start with rho:
Partial derivative of x with respect to rho: sin(phi)cos(theta)
Partial derivative of z with respect to rho: cos(phi)
Now, let's move on to phi:
Partial derivative of x with respect to phi: rho*cos(phi)*cos(theta)
Partial derivative of y with respect to phi: rho*cos(phi)*sin(theta)
Lastly, let's find the partial derivatives with respect to theta:
Partial derivative of x with respect to theta: -rho*sin(phi)*sin(theta)
Partial derivative of y with respect to theta: rho*sin(phi)*cos(theta)
Partial derivative of z with respect to theta: 0
This matrix represents the derivative matrix of the spherical coordinate transformation T.
