Answer:

Vertical angle property

Step-by-step explanation:

We are given that e is parallel to f and g is a transversal. Using the alternate interior angles property, ∠4=∠5 which is given.

Since, g is a transversal of the two parallel lines e and f, then ∠1=∠4 and ∠8=∠5 by the vertical opposite angle property.

Hence, ∠1≅∠8 by the transitive angle property.

Step-by-step explanation:

52,165 + 49,872 = 102,037

Answer:

351 adults and 275 students

Step-by-step explanation:

We can set-up a system of equations to find the number of adults. We know students and adults attended. We will let s be the number of students and a be the number of adults. Since 626 tickets were purchased, then s+a=626.

We also know that 74 fewer student tickets then adult tickets. So s+76=a, the number of student tickets plus 76 will be the number of adult tickets.

We will solve by substituting one equation into the other. We substitute a=76+s into s+a=626. Simplify and isolate the variable a.

s+a=626

s+76+s=626

2s+76=626

2s+76-76=626-76

2s=550

s=275

This means that 275 students attended and 351 adults attended since 275+351=626.

By setting up a system of equations and solving for the number of adult tickets, we are able to determine that 350 adult tickets were sold for the school play.

To find out how many adult tickets were sold, we can set up an equation to model the situation. Let A be the number of adult tickets and S be the number of student tickets. We are given that a total of 626 tickets were sold, which can be described by the equation A + S = 626. We are also told that there were 74 fewer student tickets sold than adult tickets, described by the equation S = A - 74.

To solve for A, we can substitute (A - 74) for S in the first equation, giving us A + (A - 74) = 626. Simplifying this, we get 2A - 74 = 626. Adding 74 to both sides, we get 2A = 700. Finally, dividing both sides by 2, we find A = 350.

Therefore, 350 adult tickets were sold.

Answer:

The answer is C. AAA is not a congruency postulate because the side lengths may be different sizes although the angles are the same.

triangles ABC and DEF are congruent by the Side-Side-Side (SSS) postulate.

In other words, if two triangles have all three corresponding sides equal, then the triangles are congruent.

So the answer to the question is B. Congruent - SSS.

If triangles ABC and DEF are congruent, and if so, to name the postulate that applies.

The triangles are congruent because they have the same side lengths and angles. This can be seen from the following:

AD = BE (given)

∠ADB=∠BED (vertical angles)

AB = EF (given)

∠ABD=∠EBD (corresponding angles when  AD ∥ EF  )

BC = DF  (given)

Therefore, triangles ABC and DEF are congruent by the Side-Side-Side (SSS) postulate

Answer:

Step-by-step explanation:

Start with (1,2) . One of the pairs has to begin with a 1. Look around to see which set of points has a 1 for the x value.

B and C do. So all you have gotten rid of is A and D.  D looks like it might work, but it really does not. It has - 1 as it's starting point. The point must start with 1.

The next step is to find the distance between the 2 given points. The y value for the two points already on the graph is the same so they do not contribute anything to the distance. -3 and 1 are 4 units apart.

1 and ? must also be 4 units apart. Only D does. 1 and -3 are the x values 2 and 6 are the y values. The answer is B

Answer:

Answer is B) 120

Answer: 1.1 seconds

Step-by-step explanation:

leap = 4t²  ; leap = 4 ft 11 inches, find t

[tex]4\frac{11}{12} = 4t^2[/tex]

[tex]\frac{59}{12} = 4t^2[/tex]

[tex]\frac{59}{48} = t^2[/tex]

[tex]\sqrt{\frac{59}{12}} = \sqrt{t^2}[/tex]

[tex]\sqrt{1.23} = t[/tex]

1.1 = t

First multiply C by F by multiplying each row in C by each column in F:

12 * -2 + 0*0 + 1.5*2   12*0 + 0*8 + 1.5*1

1*-2 -6*0 +7.2       1*0-6*8 +7*1

to get a matrix of:

-21   1.5

12   -41

Now subtract that matrix from B:

2- -21 = 2+21 = 23

8 - 1.5 = 6.5

0.6 - 12 = -11.4

3 - -41 = 3+41 = 44

So you have:

23   6.5

-11.4   44

Which makes C the correct answer.

Answer:

$3.6

Step-by-step explanation:

We are told that the pie store is having a 20% off sale on all of its pies. The pie you want regularly costs $18.

To find the amount saved with the discount let us find 20% of 18.

[tex]\text{The amount saved with discount}=\frac{20}{100}\times 18[/tex]

[tex]\text{The amount saved with discount}=0.20\times 18[/tex]

[tex]\text{The amount saved with discount}=3.6[/tex]

Therefore, the amount saved with the discount is $3.6.

Answer:

Exactly 12 years it will take for these trees to be the same height

Step-by-step explanation:

Slope intercept form: An equation of line is in the form of [tex]y = mx+b[/tex] where m is the slope or unit rate and b is the y-intercepts.

Let x represents the time in years and y represents the height of the tree.

Use conversion:

1 ft = 12 inches

As per the given statement:

Type A is 8 feet tall and grows at a rate of 3 inches per year.

⇒unit rate per year = 3 inches = [tex]\frac{1}{4}[/tex] ft

Then, we have;

[tex]y =\frac{1}{4}x + 8[/tex]                      ......[1]

Similarly for;

Type B  is 7 feet tall and grows at a rate of 4 inches per year.

⇒unit rate per year = 4 inches = [tex]\frac{1}{3}[/tex] ft

then;

[tex]y =\frac{1}{3}x + 7[/tex]                   .....[2]

To find after how many years it will take for these trees to be the same height.

Since, trees to be the same height;

⇒equate [1] and [2], to solve for x;

[tex]\frac{1}{4}x + 8 = \frac{1}{3}x +7[/tex]

Subtract 7 from both sides we get;

[tex]\frac{1}{4}x + 8-7= \frac{1}{3}x +7-7[/tex]

Simplify:

[tex]\frac{1}{4}x + 1= \frac{1}{3}x[/tex]

Subtract [tex]\frac{1}{4}x[/tex] from both sides we get;

[tex]1= \frac{1}{3}x-\frac{1}{4}x[/tex]

Simplify:

[tex]1 = \frac{x}{12}[/tex]

Multiply both sides by 12 we get;

x = 12

Therefore, exactly it will take for these trees to be the same height is, 12 years

Identity to verify:

[tex]\dfrac{\cot x}{1+\csc x}=\dfrac{\csc x-1}{\cot x}[/tex]

Recall that

[tex]\cos^2x+\sin^2x=1[/tex]

Divide both sides by [tex]\sin^2x[/tex] and we get

[tex]\cot^2x+1=\csc^2x[/tex]

or

[tex]\cot^2x=\csc^2x-1=(\csc x-1)(\csc x+1)[/tex]

So if we multiply the numerator and denominator of

[tex]\dfrac{\cot x}{1+\csc x}[/tex]

by [tex]\csc x-1[/tex], we get

[tex]\dfrac{\cot x(\csc x-1)}{(1+\csc x)(\csc x-1)}=\dfrac{\cot x(\csc x-1)}{\csc^2x-1}=\dfrac{\cot x(\csc x-1)}{\cot^2x}[/tex]

Then as long as [tex]\cot x\neq0[/tex], we can cancel terms to end up with

[tex]\dfrac{\csc x-1}{\cot x}[/tex]

and establish the identity.

Answer:

B

Step-by-step explanation:

Because the angles make up the interior parts of the triangle without the extra endings

Answer: The answer would be B

You solve the substitution method to solve a system of equality by expressing one variable in terms of the other using one equation, and then plugging this expression in the other(s).

In this case, the first equation gives us a way to express n in terms of m. So, we can replace every occurrence of n in the second equation with the given formula.

The result is

[tex] 14m+2n=-8 \iff 14m+2(-7m-4)=-8 \iff 14m-14m-8=-8 \iff -8=-8 [/tex]

So, the second equation turned to be an equality, i.e. an equation where both sides are the same.

This implies that the system has infinitely many solutions, because every couple [tex] (n,m) [/tex] such that [tex] n=-7m-4 [/tex] is a solution to the system, because it satisfies both equations: the first is trivially satisfied, whereas the second is an identity, and as such is satisfied by any value of the variable.

Answer:

-9sqrt(5)

Step-by-step explanation:

-2 sqrt20 - sqrt125

Lets simplify the square roots

sqrt(ab) = sqrt(a)sqrt(b)

-2 sqrt(4) sqrt(5) - sqrt(25) sqrt(5)

-2 *2sqrt(5) - 5sqrt(5)

-4sqrt(5) -5sqrt(5)

-9sqrt(5)

So firstly, we need to isolate the x terms onto one side. To do this, subtract 48 on both sides of the equation:

[tex]2x^2-20x=-48[/tex]

Next, divide both sides by 2:

[tex]x^2-10x=-24[/tex]

Next, we are gonna make the left side of the equation a perfect square. To find the constant of this soon-to-be perfect square, divide the x coefficient by 2 and then square the quotient. Add the result onto both sides of the equation:

[tex]-10 \div 2=-5\\(-5)^2=25\\\\x^2-10x+25=1[/tex]

Now, factor the left side:

[tex](x-5)^2=1[/tex]

Next, square root both sides of the equation:

[tex]x-5=\pm 1[/tex]

Next, add 5 to both sides of the equation:

[tex]x=5\pm 1[/tex]

Lastly, solve the left side twice -- once with the plus sign and once with the minus sign.

[tex]x=6,4[/tex]

In short, x = 6 and 4

Answer: x = 4   x = 6

Step-by-step explanation:

2x² - 20x + 48 = 0

2x² - 20 x + _____ = -48 + ______      subtracted 48 from both sides

2(x² - 10x + _____ ) = 2(-24 + _____ )   factored out 2 from both sides

x² - 10x + _____  = -24 + _____          divided both sides by 2

x² - 10x + 25  = -24 +25          added 25 to both sides

       ↓        ↑            ↑

     [tex]\dfrac{-10}{2}=(-5)^2[/tex]     [tex]\bigg(\dfrac{b}{2}\bigg)^2[/tex] makes a perfect square

(x - 5)² = 1             simplified

[tex]\sqrt{(x-5)^2} =\sqrt{1}[/tex]    took square root of both sides

x - 5 = ± 1             simplified

x - 5 = 1       x - 5 = -1     split into two separate equations

   x = 6           x = 4       solved for x

The interpretation of [tex]R^{2}[/tex] is the amount of variation in response variable that is explained by the explanatory variable in the model

Therefore, the interpretation of [tex]R^{2}=12.7\%[/tex] is 12.7% of variation in gpa response variable is explained by the jobs explanatory variable in the given linear regression model.

the R-squared statistic of 12.7% suggests that there is a weak linear relationship between the number of hours worked and GPA among the sampled students, and the majority of the variation in GPA is due to factors beyond the number of hours worked.

The R-squared statistic, often denoted as R², measures the goodness of fit of a linear regression model. In this context, where the R-squared statistic is 12.7%, it means that approximately 12.7% of the variability in GPA can be explained by the linear relationship with the number of hours per week students work.

More specifically:

- 12.7% of the variation in GPAs among the students in the sample can be accounted for by the linear regression model with the number of hours worked as the predictor variable.

- The remaining 87.3% of the variability in GPAs is not explained by this model and is attributed to other factors or sources of variation that are not included in the model.

In summary, the R-squared statistic of 12.7% suggests that there is a weak linear relationship between the number of hours worked and GPA among the sampled students, and the majority of the variation in GPA is due to factors beyond the number of hours worked.

Answer:

ds/dt =8  when t =1.5

Step-by-step explanation:

s = t^2 + 5t - 8

We want to find ds/dt

ds/dt = 2t +5

evaluated when t=1.5

ds/dt = 2(1.5) +5

ds/dt = 3+5

ds/dt =8  when t =1.5

Replace t with 1.5 seconds and solve for s:

s = 1.5^2 + 5(1.5) -8

s = 2.25+7.5-8

s= 9.75 -8

s = 1.75

Rate of change is S/t

Rate of change = 1.75 / 1.5

Rate of change of s = 1.17

((6x+9) (x+12) -sqrt(49+76) ^2

--------------------------------------------

(49+7x) -64

Lets simplify the numerator

((6x+9) (x+12) -sqrt(49+76) ^2

Simplify what is inside the last parentheses

Answer:

224 stamps.

Step-by-step explanation:

We have been given that Becki put 14 stamps on each page.

To find the total number of stamps that Becki put in the book we will multiply the number of stamps put on each page by the number of completely filled pages.

[tex]\text{The total number of stamps in the book}=14\times 16[/tex]

[tex]\text{The total number of stamps in the book}=224[/tex]

Therefore, Becki put 224 stamps in the book.

To find out how many stamps Becki added to her collection, we multiply the number of stamps per page, which is 14, by the number of filled pages, which is 16, resulting in a total of 224 stamps.

To determine how many stamps Becki put into her stamp collection book, we need to calculate the total number of stamps populated over the completely filled pages. She placed 14 stamps on each page and filled 16 pages. The total number of stamps is the product of the number of stamps on each page and the number of pages filled.

The formula we will use is:

Total stamps = Number of stamps per page x Number of filled pages

Substituting the given values:

Total stamps = 14 stamps/page x 16 pages = 224 stamps

Therefore, Becki put 224 stamps in her stamp collection book.

Given Equations :

✿  5x + 3y = -6 -------------- [1]

✿  3x - 2y = 4 -------------- [2]

Multiplying Equation [1] with 2, We get :

⇒ 10x + 6y = -12 ----------- [3]

Multiplying Equation [2] with 3, We get :

⇒ 9x - 6y = 12 ---------- [4]

Adding Both Equations [3] and [4], We get :

⇒ (10x + 6y) + (9x - 6y) = -12 + 12

⇒ 19x = 0

⇒ x = 0

Substituting x = 0 in Equation [1], We get :

⇒ 5(0) + 3y = -6

⇒ 3y = -6

⇒ y = -2

⇒ (x , y) = (0 , -2)

Option (a) is the Answer

Answer: A (0, -2)

Step-by-step explanation:

5x + 3y = -6   →   2(5x + 3y = -6)   →   10x + 6y = -12

3x  - 2y =  4   →   3(3x  - 2y =  4)   →   9x  - 6y = 12

                                                          19x           =  0

                                                              x          =  0

Now, input "x = 0" into one of the equations and solve for y:

5x + 3y = -6

5(0) + 3y = -6

         3y = -6

           y = -2
