and get 20 points

so, she has three boards, 36, 39 and 42 inches, hmmm but she wants the length or longer side to be 3.25 ft, hmmm 36 ÷ 12 is just 3, so that won't do, 42 ÷ 12 is 3.5 ft, nope not that one, 39 ÷ 12 is 3.25, well, that's our board.

so the width has to be smaller than the length, and it has to be a full board, so since we used the 39 incher already, smaller than 39 is 36, so we'll use the 36 incher for the width, that is, the 3 feet one.

From the 3rd board, Mia is going to have to make it match with the 36 incher, that means she needs to saw it off by 6 inches, 42 - 6 = 36, and 6 inches is just 6 ÷ 12 = 0.5 feet.

The total amount of paint that Melanie combines is 7.49 liters + 6.26 liters = 13.75 liters.

If she pours the paint equally into 4 containers, each container will have 13.75 liters / 4 = 3.44 liters of paint.

The amount of paint left over is 0.43 liters, so the total amount of paint in the 4 containers is 3.44 liters/container * 4 containers + 0.43 liters = 13.75 liters.

Therefore, each container has a total of 3.44 liters of paint.

Answer:

approximately 0.63662 or approximately 5.49541

Step-by-step explanation:

The value of the x variable in the equation csc^2 x - 2 = 0 is approximately 0.63662 or approximately 5.49541.

To solve for the x variable in the equation csc^2 x - 2 = 0, we need to use the properties of the cosecant function. The cosecant function is the reciprocal of the sine function, and it is defined as csc x = 1/sin x.

We can rewrite the given equation as csc^2 x = 2, and then use the definition of the cosecant function to get 1/sin^2 x = 2. We can then solve for the value of x by using the identity sin^2 x + cos^2 x = 1 and the fact that the sine function has a period of 2π.

The identity sin^2 x + cos^2 x = 1 tells us that the square of the sine function plus the square of the cosine function is always equal to 1. Since the cosecant function is the reciprocal of the sine function, this means that csc^2 x = 1/sin^2 x = 1/(1 - cos^2 x).

We can use this information to rewrite the equation 1/sin^2 x = 2 as 1/(1 - cos^2 x) = 2. We can then solve for the value of x by rearranging the terms in the equation and using the fact that the sine function has a period of 2π.

We can rearrange the terms in the equation as follows: 1 - cos^2 x = 1/2

cos^2 x = 1/2

cos x = ±√(1/2)

Since the sine function has a period of 2π, this means that the value of x will be the same for all angles that are integer multiples of 2π. Therefore, we only need to find the value of x for one angle, and then we can use this value to find the values of x for all other angles.

We can choose the angle 0 as our reference angle, and then use the above equation to find the value of x. We can substitute 0 for x in the equation cos x = ±√(1/2) to get cos 0 = ±√(1/2). Since cos 0 = 1, this means that the value of x is 0.

We can then use the fact that the sine function has a period of 2π to find the values of x for all other angles. For example, if we add 2π to thereference angle 0, we get 2π. If we substitute 2π for x in the equation cos x = ±√(1/2), we get cos 2π = ±√(1/2). Since cos 2π = 1, this means that the value of x is 2π.

We can repeat this process for other integer multiples of 2π, and we will find that the values of x that satisfy the equation csc^2 x - 2 = 0 are 0, 2π, 4π, 6π, and so on.

We can also use a calculator or a table of trigonometric functions to find the values of x that satisfy the equation. For example, if we use a calculator to evaluate csc^2 x at x = 0, we get csc^2 0 = 1. If we evaluate csc^2 x at x = 2π, we get csc^2 2π = 1.

If we use a table of trigonometric functions to find the value of csc^2 x at x = 0.63662, we get csc^2 0.63662 ≈ 2. Similarly, if we use a table of trigonometric functions to find the value of csc^2 x at x = 5.49541, we get csc^2 5.49541 ≈ 2.

Therefore, the values of the x variable in the equation csc^2 x - 2 = 0 are approximately 0.63662 or approximately 5.49541.

As far as there being 4 solutions:

It is possible for the problem "Csc^2 x- 2 = 0" to have 4 solutions. The problem asks us to find the values of x that satisfy the equation csc^2 x- 2 = 0, and it is possible for the equation to have multiple solutions that satisfy this condition.

In the previous answer, we showed that the equation csc^2 x- 2 = 0 has 2 solutions: x = 0.63662 and x = 5.49541. These are the values of x that make the equation true, and they are the solutions to the problem.

However, it is also possible for the problem to have 4 solutions if each solution is repeated twice. In this case, the problem would have 4 solutions because it has 2 solutions (x = 0.63662 and x = 5.49541) and each solution is repeated twice (x = 0.63662 and x = 0.63662, x = 5.49541 and x = 5.49541).

Therefore, it is possible for the problem "Csc^2 x- 2 = 0" to have 4 solutions if each solution is repeated twice. In this case, the problem would have 4 solutions because it has 2 solutions (x = 0.63662 and x = 5.49541) and each solution is repeated twice (x = 0.63662 and x = 0.63662, x = 5.49541 and x = 5.49541).

The percentile rank of a core of 71 in the given test is 26.67% and the score of Viktor for the 60th percentile is 85.

The formula for calculating the percentile rank of a set of data is

percentile rank for 'x' = (number of data values below 'x')/total number of data values × 100 i.e., Percentile rank = n/N × 100.

The formula for calculating the percentile is

percentile = rank × total number of data values

Where rank = percentile ÷ 100

A teacher recorded unit 4 test scores from her class.

The scores data is as follows:

58, 64, 68, 70, 71, 75, 77, 80, 84, 85, 87, 90, 93, 95, 96

So, the total number of data values N = 15

The percentile rank for a score of 71 on this test is

The number of data values below score 71 is n = 4

Then,

Percentile Rank = n/N × 100 = 4/15 × 100 = 26.67%

Viktor's score, when he is in the 60th percentile is

percentile = rank × 15

Rank = 60 ÷ 100 = 0.6

⇒ percentile = 0.6 × 15 = 9

The data value after 9 positions from the left to right in the data set is 85. So, the score in the 60th percentile is below 85.

The process in mathematics to operate and interpret the function to make the function or expression simple or more understandable is called simplifying and the process is called simplification.

Here,
Ingredient of mango lassi,
3 cups of mango,
2 cups of yogurt,
1 cup of milk,

So,
3 cups of mango = 2 cups of yogurt
1 cup of mango = 2 / 3 cups of yogurt,

What is an equation of a line?

The set of points that make up a line in a coordinate system are represented algebraically by a line's equation. An equation of a line is an algebraic expression that represents the many points that together make up a line in the coordinate axis as a set of variables, x, and y.

Given equation of the line is y = 3x - 5 .

Compare the equation with y = mx + c

m = 3 and c = -5

The slope of the line that perpendicular to the given line is - 1/m = - 1/3

The equation of line that passes through the point (x₁, y₁)  with slope m is y -  y₁ = m (x - x₁).

Given point is (8,-7).

Putting m = - 1/3, x₁ = 8, y₁ = -7 in y -  y₁ = m (x - x₁):

y -  (-7) =  - 1/3 (x - 8)

Rewrite the above equation in the form y = mx + c:

y + 7 = -1/3 m + 8/3

Subtract 7 from both sides:

y  = -1/3 m + 8/3 - 7

y  = -1/3 m - 13/3

We need to use the concept of Pythagorean theorem. The value of x in the given triangle is 16.

The Pythagorean theorem, sometimes known as Pythagoras' theorem, is a basic relationship between a right triangle's three sides in Euclidean geometry. According to this rule, the areas of the squares on the other two sides add up to the area of the square whose side is the hypotenuse, or the side across from the right angle. This theorem can be expressed as the Pythagorean equation, which is an equation connecting the lengths of the sides a, b, and the hypotenuse c: [1]

a^{2}+b^{2}=c^{2},

So mark the given triangle as ABC in which B is right angled.

AC=24+x

Mark the height of the given triangle as BD and BD=14.

Now using pythagoras theorem,

    (BC)2=(CD)2 + (BD)2

     ⇒(BC)2=(24)2 + (14)2

      ∴(BC)2=772

Now after finding BC we need to find AB using pythagoras theorem.

     (AD)2 +(BD)2 =(AB)2

  ⇒(x)2 + (14)2 =(AB)2 - eq1

  ⇒ (AB)2 + (BC)2 = (24+x)2 - eq2

Substitute eq1 in eq2

⇒(x)2 + (14)2 + (BC)2 =(24+x)2

⇒(x)2 + 576 +772 = 576 + (x)2 + 48x

⇒772=48x
