Answer 1

Answer:

 x² - 49

Step-by-step explanation:

Identity: (a + b)(a - b) = a² - b²

  Here a = x and b = 7

(x +7) (a -7) = x² - 7²

                  = x² - 49

Answer: ∠BAC = 70°

Step-by-step explanation:

    We will use the "Exterior Angle Property" which states that an exterior angle of a triangle is equal to the sum of its two opposite non-adjacent interior angles.

   This means that (6a) + (7a) = 130° which we can solve.

(6a) + (7a) = 130°

13a = 130

a = 10°

    Now that we have the value of a, we can solve for the angle BAC.

7a

[tex] \bold{ x = - \frac{5}{6} }[/tex]

Step-by-step explanation:

⠀⠀⠀⠀■ Question

[tex] \large \sf{ \frac{4x + 9}{3x + 11} = \frac{4x + 3}{3x + 2} }[/tex]

Solve for x.

⠀⠀⠀⠀□ Solution

We will cross multiply the above equation

[tex] \sf (4x + 9)(3x + 2) = (4x + 3)(3x + 11) \\ \\ \sf 4x(3x + 2) + 9(3x + 2) = 4x(3x + 11) + 3(3x + 11) \\ \\ \sf 12 {x}^{2} + 8x + 27x + 18 = 12 {x}^{2} + 44x + 9x + 33 \\ \\ \sf 12 {x}^{2} + 35x + 18 = 12 {x}^{2} + 53x + 33[/tex]

Now we will take the values of RHS(right hand side) to LHS(left hand side) of the equation. During this, the values of RHS will get opposite sign while going to LHS.

[tex] \sf 0 = 12 {x}^{2} + 53x + 33 - 12 {x}^{2} - 35x - 18 \\ \\ \sf 0 = 18x + 15[/tex]

Taking 15 to LHS

[tex] \sf - 15 = 18x[/tex]

Dividing both RHS and LHS of the equation by 18

[tex] \large{ \sf \frac{ - \cancel{15} \tiny {5}}{ \cancel {18} \tiny6 } = x} \\ \\ \boxed{ x = - \frac{5}{6} }[/tex]

Answer:

[tex]\textsf{$x=-\dfrac{5}{6}$}[/tex]

Step-by-step explanation:

Given: [tex]\textsf{$\dfrac{4x+9}{3x+11}=\dfrac{4x+3}{3x+2}$}[/tex]

1. Cross-multiply

(4x + 9)(3x + 2) = (4x + 3)(3x + 11)

2. Distribute

⟶ (4x + 9)(3x + 2) = (4x + 3)(3x + 11)

⟶ 4x(3x) + 4x(2) + 9(3x) + 9(2) = 4x(3x) + 4x(11) + 3(3x) + 3(11)

⟶ 12x² + 8x + 27x + 18 = 12x² + 44x + 9x + 33

3. Combine like terms

⟶ 12x² + 8x + 27x + 18 = 12x² + 44x + 9x + 33

⟶ 12x² + 35x + 18 = 12x² + 53x + 33

4. Subtract 12x² from both sides

⟶ 12x² - 12x² + 35x + 18 = 12x² - 12x² + 53x +33

⟶ 35x + 18 = 53x + 33

5. Subtract 35x from both sides

⟶ 35x - 35x + 18 = 53x - 35x + 33

⟶ 18 = 18x + 33

6. Subtract 33 from both sides

⟶ 18 = 18x + 33

⟶ 18 - 33 = 18x + 33 - 33

⟶ -15 = 18x

7. Divide both sides by 18 to isolate the variable

[tex]\longrightarrow\textsf{$\dfrac{-15}{18}=\dfrac{18x}{18}$}\\\\\\\longrightarrow\textsf{$\dfrac{-15}{18}=x$}\\\\[/tex]

8. Reduce

leaders could she choose?

Answers

Considering the definition of combination, she could choose 190 different pairs of team.

What is combination

Combinations of m elements taken from n to n (m≥n) are called all the possible groupings that can be made with the m elements in such a way that not all the elements enter; the order does not matter and the elements are not repeated.

To calculate the number of combinations, the following formula is applied:

[tex]C=\frac{m!}{n!(m-n)!}[/tex]

The term "n!" is called the "factorial of n" and is the multiplication of all numbers from "n" to 1.

Different pairs of team leaders

Ms. lewis has 20 students in her p.e. class. She puts each student's name in a hat and will select the names of 2 students at random as team leaders for a volleyball game.

So, you know that:

m= 20n= 2

Replacing in the definition of combination:

[tex]C=\frac{20!}{2!(20-2)!}[/tex]

Solving:

[tex]C=\frac{20!}{2!18!}[/tex]

C= 190

Finally, she could choose 190 different pairs of team.

Answers

In 5 days the total rental charge is the same for each store.

What is an equation?

It is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.

Given that:-

A movie store rents a game machine for $12.50 plus $1.50 per day. The downtown store rents the same machine for $4 per day with no initial fee.

Let x be the days. The two-equation will be formed as:-

Total amount = 1.5x   +   12.5  

Total amount = 4x

For the same total amount, we will equate the two equations.

1.5x   +   12.5  =  4x

12.5  =  4x  -  1.5x

12.5  =  2.5x

x  =  12.5  /  2.5

x  =  5 days

Therefore In 5 days, the total rental charge is the same for each store.

11ydx15yd= 165yd^2

11yd+15yd=26yd

Answer:

56.1, 36.2

Step-by-step explanation:

For this we need to use the Pythagorean Theorem, which is a^2+b^2=c^2. We have our a and c values, so we can make the equation 11^2+b^2=15^2, or 121+b^2=225. Next, we isolate b.

121+b^2=225

-121         -121

___         ___

0             104

b^2=104

Now, we have to find the square roots of both sides. If we do this, we get b= 10.2.

Now, we can find our perimeter:

11+15+10.2= 36.2

For area, the formula is 1/2(b)h (1/2 times the base and height), so:

1/210.2=5.1

5.1*11=56.1

The area of the garden is 13.92 square meters. A fence is planned around the perimeter of the garden. How many meters of fencing are needed?

Answers

The meters of fencing that is needed is = 3.36m

Calculation of needed meters

The garden is designed in a trapezoid form with sides= a; 3.3m and b; 5.28m.

The area of the trapezoid garden = 13.92 m²

Therefore the meters of fencing needed which is height = ?

The formula for the area of trapezoid = A = (a+b/2)h

From the formula make h the subject of formula;

h = A *2/a+b

h = 13.92*2/3.3+5.28

h =27.84/8.28

h= 3.36m

Therefore, the meters of fencing that is needed is = 3.36m.

A guidance counselor reports that in a given semester, the probability that a student chooses art as an elective is 15 percent, the probability that a student chooses art or drama is 20 percent, and the probability that a student chooses both art and drama is 2 percent. what is the probability that a student chooses drama as an elective?

Answers

The probability that a student chooses drama as an elective is 7%.

What is the concept of probability?

Probability is the study of the odds of obtaining each outcome of a random experiment. These odds are assigned the real numbers in the range between 0 and 1. Results closer to 1 are more likely to occur.

In this case, we can call:

A represents ArtD represents Drama.

So, the information given was:

P(A) = 15%P(A or D) = 20%P(A and B) = 2%

The formula will be:

P(A or D) = P(A) + P(D) - P(A and D)

So:

[tex]20\% = 15\% + P(D) - 2\%\\P(D) = 20\% - 15\% + 2\%\\P(D) = 7\%[/tex]

Answers

Based on the game involving rolling a number cube, the applicable statements are:

The sample space is {1, 2, 3, 4, 5, 6}. The expected value for the game is 0. The game is fair because the expected value is equal to 0.

What happens in a game involving rolling a number cube?

There are six sides of a number cube which means that the sample space is all the sides the cube can land on which are 1,2,3,4,5, and 6.

Because there are 3 odd numbers which can give you a negative point, and 3 even numbers which can give a point, the expected value is 0 as these cancel each other out.

This makes the game fair because situations that have an expected value of 0 are considered fair because there are no expected losses or profits.
