The whole protractor is 180 degrees. B is at the 180 mark but E is at 20. So, the the angle of BAE would be 180-20=160 degrees.

Answer:

y = 0.5x + 50.95

Step-by-step explanation:

Given y is total cost while x is total miles

Slope: m = (y2-y1)/(x2-x1)

m = (75.95-65.95)/(50-30) = 10/20 = 0.5

y = mx + b

y = 0.5x + b

75.95 = 0.5(50) + b

b = 50.95

Slope intercept form: y = 0.5x + 50.95

Answer:

$10

Step-by-step explanation:

We Know

Terri pays a monthly cell phone fee of $10. She pays 5 cents for each minute that she talks.

Let C be the total cost, and x be the number of minutes she talks; we have the equation.

C = 0.05x + 10

If Terri does not make any calls, what would her bill be?

C = 0.05(0) + 10

C = $10

So, her bill will be $10

So, Bob is 12 years old and his father is 36 years old solved by using the substitution method.

To determine the ages of Bob and his father, let's use the given information and set up two equations.

Let Bob's age be represented as B and his father's age as F. The terms provided are:

1. Bob's father is three times as old as he is: F = 3B
2. Four years ago, Bob's father was four times as old as he is: F - 4 = 4(B - 4)

Now, we can solve these equations simultaneously. Substituting the first equation into the second equation, we get:

3B - 4 = 4(B - 4)

Simplify the equation:

3B - 4 = 4B - 16

Add 4 to both sides:

3B = 4B - 12

Subtract 4B from both sides:

-B = -12

Finally, divide by -1:

B = 12

Now that we know Bob's age, we can find his father's age using the first equation:

F = 3B
F = 3(12)
F = 36

So, Bob is 12 years old and his father is 36 years old.

I am attaching the figure, that determines the answers.

The correct  is leading coefficient: 4, degree: 5, end behavior: as x approaches negative infinity, P(x) approaches negative infinity; as x approaches positive infinity, P(x) approaches positive infinity.

The correct leading coefficient of the polynomial function P(x) = 4x^5 + 9x^4 + 6x^3 - x^2 + 2x - 7 is 4. The degree of the polynomial is 5, which is determined by the highest power of x in the polynomial.

The end behavior of the function is determined by the leading term, which is the term with the highest degree. In this case, the leading term is 4x^5. As x approaches negative infinity, the value of P(x) approaches negative infinity, and as x approaches positive infinity, the value of P(x) also approaches positive infinity.

Therefore, the correct end behavior is:

- As x approaches negative infinity, P(x) approaches negative infinity.

- As x approaches positive infinity, P(x) approaches positive infinity

The given options for leading coefficient, degree, and end behavior do not match the polynomial function provided.

Step-by-step explanation:

There are 32 ounces in a quart. This problem wants you to know the cost of 2 quarts, or 64 ounces. 8 oz = $3.50, so now divide 64 by 8, = 8. Multiply $3.50(8)= $28.

9.028 many resonances will be observed when a tuning fork with a frequency of 321 Hz is used in air with a sound speed of 342 m/s.

Given that,

When a tuning fork with a frequency of 321 Hz is used in air with a sound speed of 342 m/s, how long is the tube utilized in our experiment, 4 m?

We have to find what many of resonances will be seen.

We know that,

The length of the tube is Lₙ=4 m

Frequency is ν = 321 hz

Speed of sound is v = 342 m/s

We know that,

ν=vλ

321=342λ

λ=321/342

λ=0.938

Now,

Lₙ=(2n+1/4)λ

4=(2n+1/4)0.938

n=8.028

We get,

N=n+1=8.028+1=9.028

Therefore, 9.028 many resonances will be observed when a tuning fork with a frequency of 321 Hz is used in air with a sound speed of 342 m/s.

After answering the presented question, we can conclude that equation Therefore, the original price of the motorcycle is Rs 125700.

In mathematics, an equation is a proposition that states the equivalence of two expressions. An equation consists of two sides separated by a system of equations (=). For instance, the statement "2x + 3 = 9" states that the word "2x Plus 3" equals the integer "9". The goal of solving equations is to find the value or amounts of the variable in the model) that will permit the calculation to be accurate. Mathematics can be simple or complex, linear or nonlinear, and contain one or more parts. For example, in the equation "x2 + 2x - 3 = 0," the variable x is raised to the power of 2. Lines are used in many areas of mathematics, including algebra, arithmetic, and geometry.

Let the original price of the motorcycle be P.

Depreciation per year = 4% of P = 0.04P

Cost of motorcycle after 3 years = P - 3(0.04P) = P - 0.12P = 0.88P

\(0.88P = Rs 110592\\P = Rs (110592/0.88)\\P = Rs 125700\)

Therefore, the original price of the motorcycle is Rs 125700.

On solving the provided question, we can say that Probability of at least 2 of the 5 families have at least 2 kids with blue eyes   P =\(10/37 = 0.2703\)

A branch of mathematics known as probability measures the possibility of an event happening or a proposition being true. The probability of an occurrence is a number between 0 and 1, where roughly 0 denotes the event's improbability and 1 denotes certainty. A probability is a numerical representation of the possibility or probability that a specific event will take place. Probabilities can alternatively be stated as percentages ranging from 0% to 100%, or as percentages from 0 to 1.

The likelihood that two or more of the three kids have blue eyes is =  \((1/4 *1/4 * 1/4) + 3(1/4 * 1/4 * 3/4) = 10/64.\)

However, since it is assumed that at least one child has blue eyes, the possibility of their being no blue-eyed offspring is excluded. \((3/4 * 3/4 * 3/4) = 27/64\) is eliminated, leaving 37/64 as the remaining valid domain. As a consequence, the reciprocal of the remaining valid domain (64/37) must be multiplied by the result in (1) above (10/64). This results \(10/64 * 64/37 = 10/37.\)

The value of a = -2 and b = 3.

What is a system of equations?

A finite set of equations for which common solutions are sought is referred to in mathematics as a set of simultaneous equations, often known as a system of equations or an equation system.

Here, we have

Given: 3a - 5b = -26, a + 2b = 6

We have to solve this equation.

3a - 5b = -26...(1)

a + 2b = 6...(2)

Now we multiply equation (1) by 2 and equation (2) by 5 and we get

6a - 10b = -52....(3)

5a + 10b = 30....(4)

After solving equations (3) and (4), we get

11a = -22

a = -2

Now we put the value of 'a' in equation(3) and we get

6(-2) - 10b = -52

-10b = -52 + 12

-10b =  -30

b = 3

Hence, the value of a = -2 and b = 3.

a. Pair 2 is selected.

b. Respiratory system, its function is to breathe. Digestive system, its function is to break down food into nutrients.

c. The two systems work together by sharing the region of the mouth and upper throat.

First picture in Pair 2 is Respiratory system, which its function is to breathe. Second picture in Pair 2 is Digestive system, which its function is to break down food into nutrients such as carbohydrates, fats and proteins. The respiratory system takes in oxygen from the air, and also gets rid of carbon dioxide. The digestive system absorbs water and nutrients from the food we consume.

The respiratory system is mainly used to transport air, whilst the digestive system is used to transport fluids and solids, from water and food we eat. The respiratory and the digestive systems share the area of the mouth and upper throat, in which air, fluids, and solids can be mixed.

The digestive system does homeostasis by ensuring that the stomach area has the right pH balance. The body uses both positive and negative mechanisms to perform homeostasis. If the body detects an imbalance, the other systems work together to counterbalance and restore the right equilibrium.

To draw the directed graphs representing the five different equivalence relations on a three-element set, we can label the elements as A, B, and C. Here are the five directed graphs corresponding to each equivalence relation:

1. Reflexive Relation:

In a reflexive relation, each element is related to itself. The directed graph would have loops at each vertex representing the self-relationships:

```

A -> A

B -> B

C -> C

```

2. Symmetric Relation:

In a symmetric relation, if element A is related to element B, then element B is also related to element A. The directed graph would have arrows going in both directions between related elements:

```

A <- -> B

 ↖   ↘

   C

```

3. Transitive Relation:

In a transitive relation, if element A is related to element B and element B is related to element C, then element A is also related to element C. The directed graph would have arrows connecting elements in a transitive chain:

```

A -> B -> C

```

4. Anti-Symmetric Relation:

In an anti-symmetric relation, if element A is related to element B, then element B cannot be related to element A, unless A and B are the same. The directed graph would have arrows in one direction, with self-loops:

```

A -> B

B -> B

C -> C

```

5. Equivalence Relation:

An equivalence relation combines reflexivity, symmetry, and transitivity. The directed graph would have arrows in both directions between related elements and loops at each vertex:

```

A <- -> B
