Answer:

I got that answer also, but i just did the math in my head.

Step-by-step explanation:

We are given with three angles of triangle that are 3n , 5n and 10n.

We have to find the measure of 3n .

We know that sum of all angles of triangle is 180°.

\( \sf \: 3n + 5n + 10n = 180\degree \\ \\ \sf \:18 n = 180\degree \\ \\ \sf \:n = \dfrac{180}{18} \\ \\ \sf \:n = 10\degree \\ \\ \)

Substituting value of n in 3n ,

= 3n

= 3 × 10

= 30°

Therefore, Measure of 3n will be 30 °

Answer:

  3. ∠c = 32°

  5. 3n = 30°

Step-by-step explanation:

You want the measures of certain angles in triangles where the angles are marked with variable expressions.

The angle sum theorem tells you the sum of angle measures in a triangle is 180°. That fact is used to write an equation that can be solved for the variables used to represent angle values.

The sum of angles in the triangle is ...

  52 +3c +c = 180 . . . . angles total 180°

  4c = 128 . . . . . . . . . subtract 52

  c = 32 . . . . . . . . . divide by 4

  ∠c = 32°

The sum of angles in the triangle is ...

  10n +5n +3n = 180

  18n = 180 . . . . . . . . . collect terms

  n = 10 . . . . . . . . . . divide by 18

  3n = 3·10 = 30

The measure of angle 3n is 30°.

Using the Combination formula,

Total number of ways there to paint 10 hotel rooms in a hotel with five colours is 527 ways .

We have given that,

total number of rooms available for paint = 10

number of colour avaliabile for painting = 5

Atmost three rooms can be painted green i.e

the number of ways for atmost three rooms are painted green = ¹⁰C₃ + ¹⁰C₂ + ¹⁰C₁ = 120 + 45 + 10 = 175

similarly, the number of ways for atmost three rooms are painted red = 175

the number of ways for atmost three rooms are painted blue = 175

Now, one room is remained for painting and two colours are available for it

the number of painting the remained room with aany of two available colours i.e black and white

= 2 ways

thus , total ways to paint the 10 hotel rooms with five different paints are (175×3 +2) = 527

Answer: To find the magnitude and direction of the equilibrant of a system of forces, we first need to find the resultant of the forces, and then find the force that will balance the resultant.

For the given system of forces, we can use the Pythagorean theorem to find the magnitude of the resultant:

R = sqrt(32^2 + 48^2)

 = sqrt(1024 + 2304)

 = sqrt(3328)

 ≈ 57.7 N

The direction of the resultant can be found using trigonometry:

tan(theta) = opposite / adjacent

where theta is the angle between the forces, which is 90° in this case. We can choose either force as the adjacent side, and the other force as the opposite side. Let's choose the 32 N force as the adjacent side:

tan(theta) = 48 / 32

theta = atan(48/32)

     ≈ 56.3°

This means that the resultant has a magnitude of approximately 57.7 N and is directed at an angle of approximately 56.3° to the 32 N force.

To find the equilibrant, we need to find a force that has the same magnitude as the resultant but acts in the opposite direction. We can use the same magnitude and opposite direction to find the equilibrant as:

E = -R

 = -57.7 N

This means that the equilibrant has a magnitude of 57.7 N and acts in the opposite direction to the resultant, which is at an angle of approximately 56.3° to the 32 N force.

Answer:

39.4

Explanation:

Given the expression

9.85 × s

We are to find the equivalent value if s = 4

Substitute;

9.85 × s

= 9.85 × 4

= 9.85 × 2 * 2

= 19.7*2

= 39.4

Hence the value of the expression when s = 4 is 39.4

The solution to the initial value problem is u(t) = (-1/3)ln(3/10(1 - e^10t)) + (10/3)e^(-6). The solution involves logarithmic and exponential functions, reflecting the behavior of the given differential equation.

To solve the given initial value problem, we'll start by separating the variables. We rewrite the equation as:

du/(e^3u + 10t) = dt

Integrating both sides with respect to u and t, we have:

∫(1/(e^3u + 10t))du = ∫dt

The integral on the left side can be challenging, but we can simplify it by using a substitution. Let's substitute v = e^3u + 10t. Taking the derivative with respect to t, we get dv/dt = 3e^3u + 10. Rearranging the terms, we have 3e^3u = dv/dt - 10. Dividing by 3, we get e^3u = (1/3)(dv/dt - 10). Substituting this back into our equation, we have:

∫(1/v)dv = ∫dt

The integral of (1/v) with respect to v is ln|v|. Integrating both sides, we obtain:

ln|e^3u + 10t| = t + C

Solving for e^3u + 10t, we have:

e^3u + 10t = e^(t+C)

Next, we apply the initial condition u(0) = 6. Substituting t = 0 and u = 6 into the equation, we get:

e^(3*6) + 10(0) = e^C

e^18 = e^C

Thus, C = 18. Substituting this value back into our equation, we have:

e^3u + 10t = e^(t+18)

Finally, solving for u, we get:

u(t) = (-1/3)ln(3/10(1 - e^10t)) + (10/3)e^(-6)

This is the solution to the initial value problem. It is obtained by integrating both sides of the equation, applying the initial condition, and solving for u in terms of t.

Answer:

You divide 72 by the annual rate of return you receive on your investments, and that number is a rough estimate of years it takes to double your money.

The only point that lies on both lines is (-4,5).

To determine which of the points (−4,5), (4,3), and (1,2) lie on both the lines −x1−4x2=−16 and −3x1−5x2=−13, we need to check if the coordinates of each point satisfy both of the equations.

For the first line, we can rewrite it as x2 = (-x1 + 16)/4 and for the second line, we can rewrite it as x2 = (-3x1 + 13)/5.

Substituting the coordinates of each point into these equations, we get:

For the point (-4,5):

-4(2) + 16/4 = -4 + 4 = 0, and

-3(-4) + 13/5 = 12/5 + 13/5 = 25/5 = 5.

Therefore, (-4,5) satisfies both equations.

For the point (4,3):

4(2) + 16/4 = 8 + 4 = 12, and

-3(4) + 13/5 = -12 + 13/5 = -47/5.

Therefore, (4,3) does not satisfy both equations.

For the point (1,2):

-1(2) + 16/4 = -2 + 4 = 2, and

-3(1) + 13/5 = -3 + 13/5 = 2/5.

Therefore, (1,2) does not satisfy both equations.

Therefore, the only point that lies on both lines is (-4,5).

When given two equations, the solution can be found by solving the system of equations. To solve a system of equations, one should find the values of x and y that satisfy both equations. The solution to the system is the point (x,y) that satisfies both equations.

corresponding angles are congruent ( equal to each other )

Hence x = y

The lengths of one house may or may not be proportional to the lengths of the other house. Whether or not they are proportional depends on the specific measurements of the houses.

To determine if the lengths are proportional, we can use scale factors. A scale factor is a ratio that compares the measurements of two similar objects. If the scale factor between the lengths of the two houses is the same for all corresponding sides, then the houses are proportional.
For example, if House A has lengths of 10 feet, 15 feet, and 20 feet, and House B has lengths of 20 feet, 30 feet, and 40 feet, we can calculate the scale factor by dividing the corresponding lengths. In this case, the scale factor would be 2, because 20 divided by 10 is 2, 30 divided by 15 is 2, and 40 divided by 20 is 2. Since the scale factor is the same for all corresponding sides, the houses are proportional.

Surface area plays a role in the building of a house because it determines the amount of material needed to construct the house. The surface area is the sum of the areas of all the exposed surfaces of the house, including the walls, roof, and floor. The larger the surface area, the more materials will be required for construction.

A house with a large amount of surface area exposed to the elements has certain advantages. It allows for more natural light to enter the house, potentially reducing the need for artificial lighting during the day. It also provides more opportunities for ventilation and airflow, which can help regulate the temperature inside the house. Additionally, a larger surface area can accommodate more windows, which can enhance the views and aesthetics of the house. However, it's important to note that a large surface area also means more exposure to weather conditions, which may require additional maintenance and insulation to ensure the house remains comfortable and energy-efficient.

Step-by-step explanation:

Let initial wage = w

Percentage increase in wage = 11%

Using the relation :

New Amount = initial * (1 + % increase)

New Amount = w * (1 + 0.11)

New amount = w * (1.11)

New amount = 1.11w

the relative rate of change of each species in the reaction can be determined using stoichiometry.

The stoichiometry of the reaction tells us that for every 3 moles of species A consumed, 2 moles of species C are produced. Therefore, the relative rate of change of species A can be calculated by multiplying the rate of the reaction (0.420 m/s) by the stoichiometric coefficient of A (-3), and dividing by the stoichiometric coefficient of C (2). Similarly, the relative rate of change of species B can be calculated by multiplying the rate of the reaction by the stoichiometric coefficient of B (-1) and dividing by the stoichiometric coefficient of C (2). The relative rate of change of species C is simply equal to the rate of the reaction.

the relative rate of change of each species in the reaction can be determined by applying stoichiometry. The relative rate of change of species A is (-0.630 m/s), the relative rate of change of species B is (-0.210 m/s), and the relative rate of change of species C is (0.420 m/s).
