The value is 13

Step-by-step explanation:

You can notice that 48/12 is 4 and 20/5 is 4. Therefore, divide 52 by 4

The value of x is 13.

Two triangles are said to be similar when corresponding angles of both triangles are congruent and ratio of corresponding sides are in equal proportion.

Given that, sides of one triangle are 48, 52, and 20.

Sides of other triangle are,  12, x and 5

Since, corresponding sides are in the proportion.

                   [tex]\frac{48}{12}=\frac{20}{5}=\frac{52}{x} \\\\x=\frac{52}{4}=13[/tex]

By setting up and solving a system of equations based on the total costs and number of animals, it is determined that there were 21 birds at the shelter on Wednesday.

To solve how many birds were at the shelter on Wednesday, we can set up a system of equations based on the costs and the total number of animals. Let the number of birds be b and the number of cats be c.

The total cost for birds and cats is $161.50, and there are 43 birds and cats together. This gives us two equations:

$3.50b + $4.00c = $161.50

b + c = 43

We can solve this system of equations by first expressing c in terms of b from the second equation:

c = 43 - b

Now we can substitute c into the first equation:

$3.50b + $4.00(43 - b) = $161.50

After simplifying:

$3.50b + $172.00 - $4.00b = $161.50

Combining like terms:

-$0.50b = -$10.50

Dividing by -0.50:

b = 21

So, there were 21 birds at the shelter on Wednesday.

Answer:

a° = 118° , b° = 49° , c° = 144° , d° = 98°

Step-by-step explanation:

* Lets study the figure and take the information to solve the question

- There is a circle

- There is an inscribed triangle in the circle

- Each vertex of the triangle is an inscribed angle in the circle

- Each vertex subtended by an arc

- The measure of any inscribed angle is half the measure of its

  subtended arc

* Now lets solve the question

- The sum of the measures of the interior angles of a triangle is 180°

∵ The triangle has angle of measure 59° and another angle of

   measure 72°

∴ The measure of the third angle = 180° - (59° + 72°) = 49°

∵ b° is the measure of the third angle in the triangle

∴ b° = 49°

- The arc of measure a° is intercept the angle of measure 59°

∵ The measure of the angle is half the measure of the arc

∴ 1/2 a° = 59° ⇒ multiply both sides by 2

∴ a° = 118°

- The arc of measure c° is intercept the angle of measure 72°

∵ The measure of the angle is half the measure of the arc

∴ 1/2 c° = 72° ⇒ multiply both sides by 2

∴ c° = 144°

- The arc of measure d° is intercept the angle of measure 49°

∵ The measure of the angle is half the measure of the arc

∴ 1/2 d° = 49° ⇒ multiply both sides by 2

∴ d° = 98°

For the equation

[tex]y=\frac{x-6}{x^2+5x+6}[/tex]

There are vertical asymptotes at x=-2 and x=-3

There are no holes

Step-by-step explanation:

The equation for this graph can be factored in its denominator to get

[tex]y=\frac{x-6}{(x+2)(x+3)}[/tex]

This means that there are VA's at x=-3 and x=-2

(There are no holes as there is not a factor that cancels out.)

A function assigns the values. The asymptotes and the holes for the graph lie at x=-2 and x=-3.

A function assigns the value of each element of one set to the other specific element of another set.

The vertical asymptotes and the holes for the graph can be found by factorizing the denominator of the given function. Therefore, the factorisation of the denominator is,

x² + 5x + 6 =0

x² + 2x + 3x +6 =0

x(x+2)+3(x+2)=0

(x+2)(x+3)=0

x = -2, -3

Hence, the asymptotes and the holes for the graph lie at x=-2 and x=-3.

Answer:

A equals 254.46

C equals 56.54

Step-by-step explanation:

Area

pie (3.14) times the radius (9) times ^2 is equal to

254.46

Circumference

(2) times pi (3.14) times radius of (9) to get

56.54

Area of a circle formula = [tex]\pi[/tex]r² where r means radius and [tex]\pi[/tex] means 3.14

3.14(9)^2 = 254.34 = area

Circumference formula: 2[tex]\pi[/tex]r

2(3.14)(9) = 56.52 = circumference

The correct trigonometry formula  [tex]tan^{-1}[/tex] (71°) . Therefore ,  [tex]tan^{-1}[/tex](71°) is correct .

The correct trigonometry formula to use to solve for the given angle is the tangent formula.

This is because you are given the side opposite to the angle (48) and the side adjacent to the angle (34), and you need to solve for the angle itself (71°).

The tangent formula is:

tan(angle) = opposite / adjacent

In this case, you would have:

[tex]tan^-1[/tex] = 48 / 34

[tex]tan^-1[/tex] = 0. 708333  degree

[tex]tan^-1[/tex] = 0.71 degree

[tex]tan^-1[/tex]  (0.71)      

= 35.3112 degree.

Therefore, the correct answer is tan(71°).

After 2 months, the gym memberships at Gym A and Gym B will cost the same amount, based on the membership cost equations of each gym.

We need to determine after how many months the total costs of gym memberships at Gym A and Gym B will be the same. The cost of a gym membership at Gym A is described by the equation C = 12m + 36, where C represents the total cost and m represents the number of months. For Gym B, the cost is given by the equation C = 20m + 20.

To find the number of months where the costs are equal, we set the two equations equal to each other:

12m + 36 = 20m + 20

Subtracting 12m from both sides gives us:

36 = 8m + 20

Subtracting 20 from both sides gives us:

16 = 8m

Dividing both sides by 8 gives us:

m = 2

Therefore, after 2 months, the total costs for gym memberships at both Gym A and Gym B will be the same.

Answer:

[tex]-\frac{3\sqrt{58} i}{{58}}-\frac{7\sqrt{58}j}{{58}}[/tex]

Step-by-step explanation:

The given vector is:

v = -3i-7j

The unit vector is found by dividing the vector by its magnitude

[tex]Unit\ vector\ of\ v=\frac{v}{||v||}[/tex]

We have to find the magnitude first

So,

[tex]||v||=\sqrt{(-3)^{2} +(-7)^{2}}\\ =\sqrt{9+49}\\ =\sqrt{58}[/tex]

The unit vector is:

[tex]\frac{-3i-7j}{\sqrt{58} } \\=>-\frac{3i}{\sqrt{58}}-\frac{7j}{\sqrt{58}}\\=>(-\frac{3i}{\sqrt{58}}*\frac{\sqrt{58}}{\sqrt{58}}) -(\frac{7j}{\sqrt{58}}*\frac{\sqrt{58}}{\sqrt{58}})\\=>-\frac{3\sqrt{58} i}{{58}}-\frac{7\sqrt{58}j}{{58}}[/tex]

Therefor the last option is the correct answer ..

The unit vector in the same direction as v = -3i-7j is found by calculating the magnitude of v and then dividing v by its magnitude. The result is (-3/sqrt(58))i + (-7/sqrt(58))j.

To find the unit vector in the same direction as v = -3i-7j, we first need to calculate the magnitude (length) of v. The magnitude of a vector can be calculated using the Pythagorean theorem as applied to vector components, so for our vector v, the magnitude |v| would be sqrt((-3)^2 + (-7)^2) = sqrt(9 + 49) = sqrt(58).

Next, we find the unit vector by dividing the vector by its magnitude. This gives us: (-3/sqrt(58))i + (-7/sqrt(58))j.

Therefore, the unit vector in the same direction as v is (-3/sqrt(58))i + (-7/sqrt(58))j.

Remember that there are 100 students divided into 7-12 and 13-18 age group. So there should be 50 for each. The table should go like this:

7-12 age group

23 adventure or biography

27 - detective 

so you just have to subtract 50 from 23, which makes it 27. The remaining belongs to the 13-18 age group.

13-18 age group

1 - detective 

49 - adventure or biography.

Answer:

49

Step-by-step explanation:

Total number of students =100

Out of the 50 students in the age group 7−12 years who participated in the survey, 23 liked adventure or biography.

So, 50-23 = 27 Out of the 50 students in the age group 7−12 years who participated in the survey liked detective

Now we are given that The total number of students of both age groups who liked detective books was 28.

No. of students of age group 13-17 who like detective books = Students of both age group like detective - No.of students of 7−12 years who liked detective = 28-27 =1

So ,The total number of students of both age groups who liked adventure or biography was 100-28 = 72

Since the age group 7−12 years who participated in the survey, 23 liked adventure or biography.

So,  the age group 13-17 years who participated in the survey liked adventure or biography = 72-23=49

Age group          Adventure or Biography       Detective     Total

 7-12                              23                                    27               50  

 13-18                            49                                     1                  50

Total                             72                                    28               100

So, Option C is true.

The total number of students in the age group 13−18 years who liked adventure or biography. is 49

The solution to the equation X=(3x+10) is -5, which was found by isolating x on one side of the equation.

To solve the equation X = 3x + 10 for x, you begin by isolating the variable. First, subtract 3x from both sides, yielding -2x = 10. To find the value of x, divide both sides by -2. This results in x = -5. So, the solution for x in the given equation X = 3x + 10 is x = -5. This process involves balancing both sides of the equation to isolate the variable, and by subtracting 3x and then dividing by -2, we find that x equals -5, making it a clear and concise solution to the equation.
