help please if tan 0 = 8/15 what is sin 0

Answer:

The variable expression equation of the situation is;

x + 5 + x + 3·x - 7 = $73

The amount of money Jadah collects = $15

The amount of money Martez collects = $20

The amount of money Roana collects = $38

Step-by-step explanation:

The given parameters are;

The total amount of money they collect together = $73

The amount of money Martez collects = 5 + The amount of money Jadah collects

The amount of money Roana collects = 3 × The amount of money Jadah collects - 7

Let x represent the amount of money Jadah collects

Therefore, we have;

The amount of money Martez collects = 5 + x

The amount of money Roana collects = 3 × x - 7

The variable expression equation of the situation is given as follows;

The total amount of money the three collected = x + 5 + x + 3 × x - 7 = $73

∴ 5 × x - 2 = $73

5 × x - 2 = 73

5 × x  = 73 + 2 = 75

x = 75/5 = 15

x = 15

The amount of money Jadah collects = x = $15

The amount of money Martez collects = 5 + x = 5 + 15 = 20

The amount of money Martez collects = $20

The amount of money Roana collects = 3 × x - 7 = 3 × 15 - 7 = 38

The amount of money Roana collects = $38

The function's value at x = 1, y = - 1 Or f(1) = -1.

If both pairs of opposite sides of a quadrilateral are congruent, then the quadrilateral is a parallelogram.

Option (d) is the correct choice.

A parallelogram is a straightforward quadrilateral with two sets of parallel sides in Euclidean geometry. A parallelogram's facing or opposing sides are of equal length, and its opposing angles are of similar size.

A parallelogram has the following qualities:

The opposing sides are equally spaced and parallel.

Angles on either side are equal.

The following or neighboring angles are supplemental.

All of the angles will be at right angles if any one of them is a right angle.

The two diagonals cut across one another.

Step-by-step explanation:

To solve this question, we need to consider the two steps: transferring a student from the second class to the first class, and then randomly choosing a student from the first class.

Let's calculate the probabilities step by step:

Step 1: Transferring a student from the second class to the first class

The probability of transferring a boy from the second class is the ratio of the number of boys in the second class (13 boys) to the total number of students in the second class (13 boys + 12 girls).

P(boy transferred) = 13 / (13 + 12) = 13 / 25

Step 2: Randomly choosing a student from the first class

After the transfer, the first class will have 10 boys and 11 girls. The probability of randomly choosing a boy from the first class is the ratio of the number of boys in the first class (10 boys) to the total number of students in the first class (10 boys + 11 girls).

P(boy chosen from first class) = 10 / (10 + 11) = 10 / 21

Now, to find the overall probability, we multiply the probabilities of the two steps:

P(boy chosen) = P(boy transferred) * P(boy chosen from first class) = (13/25) * (10/21)

Therefore, the probability that the student chosen from the first class is a boy is (13/25) * (10/21), which can be simplified or approximated as needed.

The probability that the student chosen from the first class is a boy is

Step-by-step explanation:

The first law of thermodynamics is a fundamental principle in physics that states energy cannot be created or destroyed, only converted from one form to another. It can be expressed in terms of heat and work through the equation:

ΔU = q - w

where ΔU represents the change in internal energy of a system, q represents the heat added to the system, and w represents the work done on or by the system.

Now, let's address when the quantities q and w would be negative numbers.

1) When q is negative: This occurs when heat is removed from the system, indicating an energy loss. For example, when a substance is cooled, heat is extracted from it, resulting in a negative value for q.

2) When w is negative: This occurs when work is done on the system, decreasing its energy. For instance, when compressing a gas, work is done on it, leading to a negative value for w.

In both cases, the negative sign indicates a reduction in energy or the transfer of energy from the system to its surroundings.

In summary, the first law of thermodynamics can be expressed as ΔU = q - w, and q and w can be negative numbers when energy is lost from the system through the removal of heat or when work is done on the system.

The solution of the linear equation in one variable 4y - 6 = 2y + 8 is at y = 7.

According to the given question.

We have a linear equation in one variable.

4y - 6 = 2y + 8

As we know that, the linear equations in one variable is an equation which is expressed in the form of ax+b = 0, where a and b are two integers, and x is a variable and has only one solution.

Thereofre, the solution of the linear equation in one variable 4y - 6 = 2y + 8 is given by

4y - 6 = 2y + 8

⇒ 4y - 2y - 6 = 8     ( subtracting 2y from both the sides)

⇒ 2y -6 -8 = 0           (subtracting 8 from both the sides)

⇒ 2y - 14 = 0

⇒ 2y = 14

⇒ y = 14/2

⇒ y = 7

Hence, the solution of the linear equation in one variable 4y - 6 = 2y + 8 is at y = 7.

Step 2: Add y to both sides

Step 3: Divide both sides by 5

Answer:

z= \(\frac{2x}{5} + \frac{4}{5} +\frac{1y}{5}\)

Step-by-step explanation:

first get the variable z on one side by itself

5z + x – y = 3x + 4

-x                  -x

5z – y = 2x + 4

+y           +y

5z = 2x + 4+y

divide by 5 to get the answer for the variable z

5z = 2x + 4+y

\(\frac{5z}{5} = \frac {2x + 4+y}{5}\\\)

z= \(\frac{2x}{5} + \frac{4}{5} +\frac{1y}{5}\)

The required expression that gives the number of months t in terms of the price p is, t(p) =√1/2 (600-p).

The given function is p(t) = 600 − 2t².

We need to find the expression that gives the number of months t (passed since January 1) in terms of the price p.

Functions are the fundamental part of calculus in mathematics. The functions are the special types of relations. A function in math is visualized as a rule, which gives a unique output for every input x. Mapping or transformation is used to denote a function in math. These functions are usually denoted by letters such as f, g, and h.

Here, the expression that gives p in terms of t is, p(t) = 600 − 2t²----(1)

Where p represents the price and t represents the number of months t (passed since January 1).

From equation (1),

p= 600 − 2t²

⇒2t²=600-p

⇒t²=1/2 (600-p)

⇒t=±√1/2 (600-p)

But, the number of months can not be negative, t=√1/2 (600-p).

Since in this expression t is in the term of p.

Hence, the required expression that gives the number of months t in terms of the price p is, t(p) =√1/2 (600-p).
