Answers

Answer 1

The perimeter of pentagon is 150 so option D is correct.

Given:

Mr. McClary writes the equation 3(3x - 10) = 5(x + 10). The equation shows the relationship between the perimeter of an equilateral triangle and the perimeter of a regular pentagon.

3(3x-10) = 5(x+10)

9x - 30 = 5x + 50

9x - 5x = 30 + 50

4x = 80

divide by 4 on both sides

4x/4 = 80/4

x = 80/4

x = 20.

perimeter of pentagon = 5(x+10)

= 5(20+10)

= 5*30

= 150.

Therefore the perimeter of pentagon is 150 so option D is correct.

Hey, I’m really having trouble with this question and could use some help.

From the given graph, we have 2 points with coordinates:

[tex]\begin{gathered} (x_1,y_1)=(1,2) \\ \text{and} \\ (x_2,y_2)=(4,1) \end{gathered}[/tex]

The equation of a line in slope-intercept form is given by

[tex]y=mx+b[/tex]

With the given points, we can find the slope m as follows:

[tex]\begin{gathered} m=\frac{y_2-y_1}{x_2-x_1} \\ \text{then} \\ m=\frac{1-2}{4-1} \end{gathered}[/tex]

which gives

[tex]m=\frac{-1}{3}=-\frac{1}{3}[/tex]

Then, our line equation has the form

[tex]y=-\frac{1}{3}x+b[/tex]

Now, we can find the y-intercept b by substituting one of the two given points. For instance, if we substitute point (1,2) into the last result, we get

[tex]2=-\frac{1}{3}(1)+b[/tex]

which gives

[tex]\begin{gathered} 2=-\frac{1}{3}+b \\ \text{then} \\ 2+\frac{1}{3}=b \\ \frac{7}{3}=b \end{gathered}[/tex]

then, the line equations is

[tex]y=-\frac{1}{3}x+\frac{7}{3}[/tex]

a) The linear function is

[tex]f(x)=-\frac{1}{3}x+\frac{7}{3}[/tex]

b) What is f(6)?

In this case, we have that x=6. Then, by replacing this value into our function, we get

[tex]f(6)=-\frac{1}{3}(6)+\frac{7}{3}[/tex]

which gives

[tex]\begin{gathered} f(6)=-\frac{6}{3}+\frac{7}{3} \\ f(6)=\frac{-6+7}{3} \\ f(6)=\frac{1}{3} \end{gathered}[/tex]

therefore, the answer for part b is

Since it is a right triangle, you can use the trigonometric ratio sin(θ) to solve the exercise:

Graphically,

So, in this case, you have

[tex]\begin{gathered} \theta=54\text{\degree} \\ \text{ Opposite side }=72 \\ \text{ Hypotenuse }=x \\ \sin (54\text{\degree})=\frac{72}{x} \\ \text{ Multiply by x from both sides of the equation} \\ \sin (54\text{\degree})\cdot x=\frac{72}{x}\cdot x \\ \sin (54\text{\degree})\cdot x=72 \\ \text{ Divide by }\sin (54\text{\degree})\text{ from both sides of the equation} \\ \frac{\sin(54\text{\degree})\cdot x}{\sin(54\text{\degree})}=\frac{72}{\sin(54\text{\degree})} \\ x=\frac{72}{\sin(54\text{\degree})} \\ x=\frac{72}{0.8090} \\ x=88.99 \\ \text{ Rounding to the nearest tenth} \\ x=89.0 \end{gathered}[/tex]

Step-by-step explanation:

12m^2-3

Factor out the 3

3( 4m^2 -1)

3 (  ( 2m)^2 - 1^2)

Using the difference of squares ( a^2 - b^2) = ( a-b) (a+b)

3 ( 2m-1)(2m+1)

community gym charges a $50 membership fee and a $60 monthly fee. Workout gym charges a $225 fee and a $5 monthly fee. After how many months will the total amount paid to both gyms be the same?

Answers

Step 1 : Let's review the information given to us to answer the problem correctly:

Community Gym = $50 (Membership fee) + $ 60 (Monthly fee)

Workout Gym = $ 225 (Membership fee) + $ 5 (Monthly fee)

Step 2: Let's write the equation to answer the question, as follows:

Let x to represent the number of months that the total amount paid to both gyms will be the same

Community Gym = Workout Gym

Therefore,

50 + 60x = 225 + 5x

Like terms:

60x - 5x = 225 - 50

55x = 175

Dividing by 55 at both sides:

55x/55 = 175/55

x = 3.18 months

0.18 * 30 = 5.4 days

Step 3: Interpretation of the answer

Approximately after 3 months and 5 days and a half the total amount paid to both gyms will be the same

At a school concert the total value of tickets sold was $3990. Student tickets sold for $8 and adult tickets sold for $11. The number of adult tickets sold was 6 less than 4 times the number of student tickets. Find the number of student tickets sold.

Answers

The number of student tickets sold is 78.

Given,

The number of student tickets sold = x

The number of adult tickets sold = 4x - 6

Total value of tickets sold = $3990

Value of one student ticket = $8

Value of one adult ticket = $11

Now, we have to find the number of student tickets sold:

Here,

The expression :8x + 11(4x - 6) = 3990

Solve the expression:

8x + 44x - 66 = 3990

52x - 66 = 3990

Add 66 to both sides

52x - 66 + 66 = 3990 + 66

We get,

52x = 4056

Divide 52 on both sides

52x / 52 = 4056/52

That is,

x = 78

Therefore,

The number of student tickets sold is 78.

The sum of all interior angles of a triangle is 180° thus the measure of the exterior angle to ∠D is 126° so option (D) is correct.

 

What is a triangle?

A triangle is a 3-sided shape that is occasionally referred to as a triangle. There are 3 sides and three angles in every triangle, some of which may be the same.

It is known that the sum of all three angles inside a triangle will be 180°.

So,   m∠D +  m∠E +  m∠F = 180°

(3x + 27) + (4x + 22) + 68 = 180

7x + 49 + 68 = 180

7x = 63

x = 9

So,  m∠D = (3(9) + 27)° = 54°.

The exterior angle of D = 180- 54 = 126°.

Hence "The sum of all interior angles of a triangle is 180° thus the measure of the exterior angle to ∠D is 126°".

How many total students do chores? b. What is the relative frequency of students that do chores and get an allowance to the number of students that do chores? Round to the nearest hundredth if necessary.

Answers

Given the table showing the number of students who do or do not perform chores, and who do or do not receive an allowance, we can add the numbers along the rows and columns, as shown in the diagram below:

Now, that we have summed the numbers along the vertical and horizontal directions, we can now proceed to answer the questions asked.

a.) The total number of students who do chores is equal to the horizontal sum of the numbers in the 'DO CHORES' row. This value is 16

Thus, 16 students do chores

b) The relative frequency of the students that do chores and get an allowance to the number of students that do chores is simply the ratio of the value in the cell that represents an intersection of the first 'DO CHORES' row, and the first 'ALLOWANCE' column, to the value that represents the sum of all the students that do chores ( i.e, the value at the end of the first row).

Thus, this is equal to = 13/16

Therefore, 13/16 is the relative frequency of the students that do chores and get an allowance to the number of students that do chores

c) The relative frequency of the students that do not do chores nor get an allowance to the total number of students, is simply the ratio of the value in the cell that represents an intersection of the second 'DO NOT DO CHORES' row, and the second 'NO ALLOWANCE' column, to the sum of the values in the last row or the last column.

Thus, this is equal to = 4/( 18 + 7) OR 4/(16 + 9) both of which is still 4/25

Therefore, 4/25 is the relative frequency of the students that do not do chores nor get an allowance to the total number of students.

d) The students who do not do chores are a total of 9

Of this 9, the number of students that do receive their allowance fall under the 'ALLOWANCE' column, and is equal to 5.

Therefore, expressed as a percentage of those who do not do their chores, the students who do not get an allowance are = (5/9) * 100 = 55% ( to the nearest whole number)

Thus 55% of students who do not do chores do not get an allowance

Please help would really appreciate!!!!

A)  f(-1) + f(3)  = 0

B)  f(-1) - f(3)  = 0

How the functions are calculated?

[tex]f(x)=2x^{2} -4x-6[/tex]

f(-1) = 2(1) -4(-1) -6

         =2+4-6

         =6- 6

         =0

f(3) = 2(9)- 4(3) - 6

     =18- 12- 6

     =18 - 18

     = 0

A)  f(-1) + f(3)  = 0 + 0 = 0

B)  f(-1) - f(3)  = 0 - 0 = 0

What are functions?

A relationship between a group of inputs and one output each is referred to as a function. It is an association between inputs in which each input is connected to precisely one output. A domain, codomain, or range exists for every function.y = f (x) is how functions are typically represented .

Which expression can be used to find the difference of the polynomials?

Answers

[10m + (-7m)] is the formula that can be used to find the difference between the polynomials (10m - 6) and (7m - 4). + [(-6) + 4].

[10m + (-7m)] + [(-6) + 4]

With more calculation

= 10m - 7m - 6 + 4

so we do

= 3m - 2 …. (2)

As (1) and (2) are equivalent

The polynomial's differences can be calculated using the equation [10m + (-7m)] + [(-6) + 4].

In order to find the difference between the polynomials, one can utilize the formula [10m + (-7m)] + [(-6) + 4].
