[tex]111.3\ \text{square units}[/tex]

Step-by-step explanation:

[tex]PQ=20\ \text{units}[/tex]

[tex]PR=12\ \text{units}[/tex]

[tex]\angle QPR=68^{\circ}[/tex]

[tex]\angle PQR=36^{\circ}[/tex]

Area of the triangle is given by

[tex]A=\dfrac{1}{2}\times PQ\times PR\times\sin \angle QPR\\\Rightarrow A=\dfrac{1}{2}\times 20\times 12\times \sin68^{\circ}\\\Rightarrow A=111.26\approx 111.3\ \text{square units}[/tex]

The area of the triangle is [tex]111.3\ \text{square units}[/tex].

Answer:  920 ft²

Step-by-step explanation:

Closets take up 92 ft² of Maya's apartment.

From the model presented, closets account for 10% of the entire space in Maya's apartment.

The entire area of the apartment can be represented by x.

The relevant expression is:

x * 10% = 92

x = 92/10%

x = 920 ft²

Answer:

45

Step-by-step explanation:

45 seventh graders at Jonathan‘s school are not participating in the school play.

Given:

In Jonathan's school,30 seventh graders are participating in the school play. And 60% are not participating in the school play.

To find:

The number of seventh graders not participating in the school play.

Solution:

Let the total number of seventh grader be N.

Number of seventh graders participating in the school play = 30

Percentage of seventh graders not participating in the school play= 60%

Percentage of seventh graders participating in the school play:

[tex]= 100\% - 60\% = 40\%[/tex]

This means that 30 seventh graders are 40% of the total seventh graders, N.

[tex]40\%=\frac{30}{N}\times 100\\N=\frac{30}{40}\times 100=75[/tex]

The number of seventh grader not participating in the school play:

[tex]=N -30\\ = 75 - 30 = 45[/tex]

45 seventh graders at Jonathan‘s school are not participating in the school play.

Answer:

C

Step-by-step explanation:

Substitute each of the values into f(x) and if equal to zero then it is an x- intercept.

f(3)

= 3³ - 3² - 8(3) + 12 = 27 - 9 - 24 + 12 = 6 ≠ 0

f(- 4)

= (- 4)³ - (- 4)² - 8(- 4) + 12 = - 64 - 16 + 32 + 12 = - 36 ≠ 0

f(- 3)

= (- 3)³ - (- 3)² - 8(- 3) + 12 = - 27 - 9 + 24 + 12 = 0

f(4)

= 4³ - 4² - 8(4) + 12 = 64 - 16 - 32 + 12 = 28 ≠ 0

Since f(- 3) = 0 then x = - 3 is an x- intercept of f(x)

The x - intercept of the function f (x) = x³ - x² - 8x + 12 will be;

⇒ x = - 3

Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.

We have to given that;

The function is,

⇒ f (x) = x³ - x² - 8x + 12

Now,

Since, The function is,

⇒ f (x) = x³ - x² - 8x + 12

We know that;

The x - intercept of the function is satisfy the function.

So, We check all the option to find the x - intercept as;

Put x = 3;

⇒ f (x) = x³ - x² - 8x + 12

⇒ f (3) = 3³ - 3² - 8×3 + 12

⇒ f (3) = 27 - 9 - 24 + 12

⇒ f (3) = 6 ≠ 0

Put x = -4;

⇒ f (x) = x³ - x² - 8x + 12

⇒ f (-4) = (-4)³ - (-4)² - 8×-4+ 12

⇒ f (-4) = -64 - 16 + 32 + 12

⇒ f (-4) = - 36 ≠ 0

Put x = -3;

⇒ f (x) = x³ - x² - 8x + 12

⇒ f (-3) = (-3)³ - (-3)² - 8×-3 + 12

⇒ f (-3) = -27 - 9 + 24 + 12

⇒ f (-3) = 0

Thus, The x - intercept of the function is,

⇒ x = - 3

What is an Equation?

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given data ,

Let the equation be -4 ( y - 3 ) = 5 ( 2y - 6 )

On simplifying the equation , we get

-4y + ( -4 ) ( -3 ) = 10y - 5 ( 6 )

-4y + 12 = 10y - 30

Adding 4y on both sides , we get

14y - 30 = 12

Adding 30 on both sides , we get

14y = 42

Divide by 14 on both sides , we get

y = 3

Therefore , the value of y = 3

Hence , the value of the expression -4 ( y - 3 ) = 5 ( 2y - 6 ) is 3

The coordinates of the midpoint are (5.55,4.655)

Step-by-step explanation:

Midpoint

The midpoint (xm,ym) of a segment defined by points (x1,y1) and (x2,y2) is calculated as follows:

[tex]\displaystyle x_m=\frac{x_1+x_2}{2}[/tex]

[tex]\displaystyle y_m=\frac{y_1+y_2}{2}[/tex]

We are given the points (5.1 , 5.71) and (6 , 3.6). The coordinates of the midpoint are:

[tex]\displaystyle x_m=\frac{5.1+6}{2}=\frac{11.1}{2}=5.55[/tex]

[tex]\displaystyle y_m=\frac{5.71+3.6}{2}=\frac{ 9.31}{2}=4.655[/tex]
