Answer:

The tree is 36.3ft

Explanation:

Tree=11m

If 1 meter is equal to 3.3 feet we multiple the number of meters(11) to 3.3

To convert from meters to feet, we multiply the given length in meters by the conversion ratio of 3.3. The tree, being 11 meters tall, is therefore approximately 36.3 feet tall.

The question asks us to convert the height of a tree from meters to feet. The tree is 11 meters tall and we'll use the conversion rate of 1 meter being equal to 3.3 feet. To do this, we multiply the height of the tree in meters by the conversion ratio: 11 meters * 3.3 feet/meter. This gives us a height of 36.3 feet. So the tree is 36.3 feet tall.

The surface area of a triangular prism can be found by adding the areas of all faces. The triangular faces are calculated using the formula for the area of a triangle, and the rectangular faces are calculated using the given dimensions of the sides of the triangles. The total surface area is the sum of these areas.

The question is asking for the surface area of a triangular prism. In order to find this, you need to add the areas of all the faces. A triangular prism has 5 faces, 2 are triangles, and 3 are rectangles.

For the triangular faces, we use the formula for the area of a triangle which is 1/2ab, where a and b are the provided dimensions. Thus, the triangle's area is 1/2 * 20 cm * 25 cm = 250 cm². Since there are two of these, the total area is 500 cm².

The rectangular faces are more challenging since it seems like we don't have enough information. The rectangle is made up of the sides of the triangles, so one side is 20 cm. However, we don't know the length (C) of the triangle which would be the other side of the rectangle. Assuming C is given, multiply each corresponding side to get the area of each rectangle, and add all together.

The final step is to add the area of the triangles and rectangles together to find the total surface area of the prism.

Answer:

x=34

m∠S = 38

m∠T = 111

Step-by-step explanation:

Since the angles of a triangle should add up to 180, you can solve this equation:

31 + x+4 + 3x+9 = 180

the solution is x=34

Then the angles S and T can be found by substituting that value for x.

Answer:

Step-by-step explanation:

In a triangle, there are 180 degrees.

180- 31 = 149 degrees

(x + 4) + (3x+9) = 149

x=34

X+ 4 = 38

3x +9 =111

X =34, T=111, S=38

Answer:

42 3/7

Step-by-step explanation

Do long division or if you are using a calculator, divide 297 by 7.

You should receive the answer 42.428

Then, do 42 multiplied by 7. You should receive 294.

297 - 294 is 3

So if you include your 7 your final answer should be 42 3/7

Answer:

1 3/5 will be written as 8/5 in improper form.

Step-by-step explanation:

1 3/5 can also be seen as 1 + 3/5.

By making the 1 a like term, i.e. multiplying it by 5 (both numerator and denominator) we can add them as like terms.

1 will become 5/5.

5/5 * 3/5

= (5+3)/5

= 8/5

The fractional form of mixed number 1 3/5 is 8/5 .

Given,

Mixed number : 1 3/5

Here,

1 3/5 can also be seen as 1 + 3/5.

By making the 1 a like term, i.e. multiplying it by 5 (both numerator and denominator) we can add them as like terms.

1 will become 5/5.

Step-by-step explanation:

We can solve this problem by using the equation provided to us:

[tex]s = 1,856y + 45,005[/tex]

We are solving for 10 years of experience so for y, we plug in 10 as shown below. Now lets solve for s:

[tex]s = 1,856(10) + 45,005[/tex]    Multiply 1,856 by 10

[tex]s=18,560+45,005[/tex]        Add the two numbers

Answer:

5.81

Step-by-step explanation:

just did the problem

To find the value of 'a' given the angles and one side length using the Law of Sines, we calculate a ≈ 5.80 by substituting the values into the formula and solving.

To determine the value of a using the Law of Sines, we are given two angles A and B and the length of one side b. We use the equation provided:

\(\frac{\sin(A)}{a} = \frac{\sin(B)}{b}\)

Substitute the given information into the equation:

\(\frac{\sin(45^\circ)}{a} = \frac{\sin(77^\circ)}{8}\)

Next, cross multiply to solve for a:

\(8 \times \sin(45^\circ) = a \times \sin(77^\circ)\)

Finally, solve for a:

\(a = \frac{8 \times \sin(45^\circ)}{\sin(77^\circ)}\)

Use a calculator to find the approximate value of a, rounding to the nearest hundredth:

a \approx \frac{8 \times 0.7071}{0.9744}

a \approx \frac{5.6576}{0.9744}

a \approx 5.80

Betaville's Budget Surplus Model is [tex]x^2- 100x + 10000.[/tex]

We want to determine the expression that shows how much greater Alphaville’s annual budget surplus is than Betaville’s for a particular amount of tax revenue.

[tex]-2x^2+ 500x-(x^2- 100x + 10000)\\[/tex]

Opening the brackets

For this, the first thing is to calculate z, which is given by the following equation:

z = (x - m) / sd

Answer:

Step-by-step explanation:

2x + 5y = 14  -------------(i)

x + 3y = 16 ----------------(ii)

To eliminate x, multiply the second equation by  (-2)

(ii)*(-2)  -2x - 6y = -32

(i)           2x + 5y = 14       { Now add & x is eliminated}

                  - y = - 18     {divide by (-1)}

 y = 18

Plug in y =18 in Equation (i)

2x + 5*18 = 14

2x + 90 = 14

2x = 14 - 90

2x = -76

x = -76/2

x = -38

Answer:

Step-by-step explanation:

hello :

2x + 5y = 14...(*)

x + 3y = 16....(**)

multiply (**) by -2  :  -2x-6y=-32   ...(***)

add(*) and (***) : -y=-18   so y = 18

put this value in to (*) : 2x+5(18)=14
