What is the measure of KJL?

Answer:

x = -3 and y = 9

Step-by-step explanation:

          4y + 6x = 18 -----------------(I)

         3y - 2x = 33 -----------------(II)

Multiply equation (II) by 3.

(I)                 4y + 6x = 18

(II)*3            9y - 6x = 99  {Now add the equations}

                  13y        = 117

Divide both sides by 13,

                        y   = 117 ÷ 13

                          [tex]\boxed{\bf y = 9}[/tex]

Substitute y = 9 in equation (I) and obtain the value of 'x',

        4*9 + 6x = 18

           36 + 6x = 18

Subtract 36 from both sides,

                    6x = 18 - 36

                    6x = -18

Divide both sides by 6

                      x = -18 ÷ 6

                     [tex]\boxed{\bf x = -3}[/tex]

[tex] \\ 4y + 6x = 18 \\ \\ 6x= 18 - 4y \\ = x = 3 - \frac{2}{3 }y \\ x = - \frac{2}{3} y+ 3[/tex]

Answer:

Let's start by assigning a variable to the original side length of the square photograph. We'll use g to represent this length.

According to the problem, each side of the new photograph will be 1 inch more than twice the original side length g. This means that the new side length will be:

2g + 1

Since this is a square photograph, all four sides are equal in length. Therefore, the area of the new photograph can be represented by the square of the new side length:

(2g + 1)^2

To simplify this expression, we can use FOIL (First, Outer, Inner, Last) to expand the squared binomial:

(2g + 1)^2 = (2g + 1)(2g + 1)

= 4g^2 + 2g + 2g + 1

= 4g^2 + 4g + 1

So the trinomial that represents the area of the enlarged photograph is:

4g^2 + 4g + 1

To check our work, we can plug in a value for g and compare the areas of the original and enlarged photographs. For example, if g = 2 (meaning the original side length is 2 inches), then the area of the original photograph is:

2^2 = 4 square inches

And the area of the enlarged photograph is:

4(2)^2 + 4(2) + 1 = 25 square inches

This makes sense, since the new photograph has sides of length 2(2) + 1 = 5 inches, and therefore an area of 5^2 = 25 square inches, which is indeed 1 inch more than twice the original area of 4 square inches.

The required angle of the incline of the hill, to the nearest degree, is 37 degrees.

We can use trigonometry to find the angle of the incline of the hill.

we can see that Nick has hiked 10 miles up the hill, and is now at point A. His starting point is at point O, which is 8 miles east of A. Let's call the angle at A, between the incline of the hill and the horizontal ground, theta.

We can use the tangent function to find theta:

[tex]$$\tan(\theta) = \frac{h}{8}$$[/tex]

where h is the height of the hill (the distance from A to the horizontal ground at O).

We know that Nick hiked 10 miles up the hill, so we can use the Pythagorean theorem to find h:

[tex]$$h^2 = 10^2 - 8^2 = 36$$[/tex]

Therefore,

[tex]$$h = \sqrt{36} = 6$$[/tex]

Substituting into the equation for tangent, we get:

[tex]$\tan(\theta) = \frac{6}{8} = 0.75$$[/tex]

To find the angle whose tangent is 0.75, we can use the arctangent function:

[tex]$$\theta = \arctan(0.75)$$[/tex]

Using a calculator, we find that

[tex]$$\theta \approx 36.87^{\circ}$$[/tex]

Therefore, the angle of the incline of the hill, to the nearest degree, is 37 degrees.

The submarine will take 14 seconds to safely reach the surface.

Speed is a measure of how quickly an object is moving, calculated as the distance traveled per unit time.

The submarine rises 183 feet, which means its depth decreases by 183 feet. Therefore, its depth is now 375 - 183 = 192 feet below sea level.

The submarine then dives 228 feet, which means its depth increases by 228 feet. Therefore, its depth is now 192 + 228 = 420 feet below sea level.

To reach the surface, the submarine needs to ascend a distance of 420 feet.

The speed of the submarine is given as 30 feet per second. Therefore, the time it will take for the submarine to reach the surface can be calculated as:

[tex]Time = \frac{Distance}{Speed} = \frac{420}{30}[/tex]

If the ratio of dogs to cats is 2:3 and there are 520 dogs, the number of cats is 780.

The ratio refers to the relative size of one quantity or value compared to another quantity or value.

Ratios are proportionate values stated in ratio form using (:), in percentages or fractions.

The ratio of dogs to cats = 2:3

The sum of ratios = 5

The number of dogs based on this ratio = 520 dogs

The total number of dogs and cats based on the above ratio and the number of dogs = 1,300 (520/2 x 5)

The ratio of cats to dogs = 3:2 or 3/5

The number of cats = 780 (1,300 x 3/5)

Thus, using the ratio of dogs to cat, with the number of dogs as 520, there are 780 cats.

The equation given is:

396 = 66t

This equation relates the distance traveled (396 miles) to the rate of travel (66 miles per hour) and the time it takes to travel that distance (t hours).

We can rearrange this equation to solve for the constant of proportionality, which is the rate of travel:

66t = 396

Dividing both sides by 66, we get:

t = 6

Therefore, the constant of proportionality in the equation is 66. The correct answer is C.

Therefore , the solution of the given problem of probability comes out to be 3 flights will depart on time is roughly 0.311, the likelihood that at most 4 flights will depart on time is roughly 0.672,

Finding the likelihood that a claim is true or that a specific event will occur is the primary objective of the branch of mathematics known as parameter estimation. Any number between range 0 but rather 1, where 1 is usually used to symbolise certainty and 0 is typically used to represent possibility, may be utilized to represent chance. A probability diagram shows the chance that a specific event will occur. .

Here,

=> P(X = k)  = (n choose k) * p * k * (1-p) (n-k)

where p is the chance of success and (1-p) is the probability of failure, (n choose k) is the binomial coefficient, and P(X = k) is the probability of k successes in n trials.

The likelihood that precisely 3 planes will depart on time is:

P(X = 3)

=> (6 choose 3) * 0.60 * 0.40 * 0.311

The likelihood that up to 4 planes depart on time is:

=> P(X <= 4) = P(X = 0) + P(X = 1) + P(X = 2) + P(X = 3) + P(X = 4)

         = > (6 choose 0) * 0.60^0 * 0.40^6 + (6 choose 1) * 0.60^1 * 0.40^5 + (6 choose 2) * 0.60^2 * 0.40^4 + (6 choose 3) * 0.60^3 * 0.40^3 + (6 choose 4) * 0.60^4 * 0.40^2

         ≈> 0.672

The likelihood that at least three planes will depart on time is:

P(X >= 3) = 1 - P(X < 3)

         = 1 - P(X = 0) - P(X = 1) - P(X = 2)

         = 1 - (6 choose 0) * 0.60^0 * 0.40^6 - (6 choose 1) * 0.60^1 * 0.40^5 - (6 choose 2) * 0.60^2 * 0.40^4

         ≈ 0.695

=> P(X>=3) = 1 - P(X3) = 1 - P(X0) - P(X = 1) - P(X = 2)

=>  1 - (6 choose 0) (6 choose 0) * 0.60^0 * 0.40^6 - (6 choose 1) (6 choose 1) * 0.60 * 0.40 * 6 (select 2) * 0.60 * 0.40 * 4

≈> 0.695

Therefore, the likelihood that precisely 3 flights will depart on time is roughly 0.311, the likelihood that at most 4 flights will depart on time is roughly 0.672, and the likelihood that at least 3 flights will depart on time is roughly 0.695.

In mathematics, the word "of" is also regarded as one of the arithmetic operations, denoting multiplication between brackets. So far, 312440 copies have been sold.

A number or ratio that can be expressed as a fraction of 100 is referred to as a percentage in mathematics. If we need to calculate a percentage of a number, we should divide it by its entirety and then multiply it by 100. The percentage therefore refers to a part per hundred. Per 100 is what the word percent means.
In mathematics, the word "of" is also regarded as one of the arithmetic operations, denoting multiplication between brackets.
We are given that the copies sold on first release date= 42800 copies.

And this is the 7.3 of the number of copies sold on date.

So, let the number of copies sold out on date is x.

Therefore, x= 7.3*42800 OR [tex]x= \frac{73}{10} * 42800= 73*4280= 312440[/tex]

Hence, the number of copies sold out on the date are 312440.

The measure of the smaller angle is 10 degrees. We find the measure of the larger angle, we can substitute x = 10 into the expression, the measure of the larger angle is 170 degrees.

When two angles form a linear pair, they are adjacent angles that share a common side and form a straight line. The sum of the measures of these two angles is always 180 degrees.

Let x be the measure of the smaller angle in this problem. Since the ratio of the measures of the two angles is 1:17, we can express the measure of the larger angle in terms of x by multiplying 17 to x. Thus, the measure of the larger angle is 17x.

To find the value of x, we can use the fact that the sum of the measures of the two angles is 180 degrees. So we have:

x + 17x = 180

Simplifying the equation, we get:

18x = 180

Dividing both sides by 18, we obtain:

x = 10

Therefore, the measure of the smaller angle is 10 degrees. To find the measure of the larger angle, we can substitute x = 10 into the expression we derived earlier for the measure of the larger angle:

17x = 17(10) = 170 degrees

Hence, the measure of the larger angle is 170 degrees.

Since, the triangle FGH is a right angle triangle, The angles of the ∠F = 62°, ∠G = 90° and ∠H = 28°.

Right Angle Triangle:

A right triangle (American English) or right triangle (UK), or more formally an orthogonal triangle, formerly known as a right triangle, is a triangle in which one angle is a right angle (i.e. say an angle of 90 degrees), i.e. two of its sides are perpendicular. The relationship between the sides of a right triangle and the other angles is the basis of trigonometry.

According to the Question:

Interior angles of a triangle add up to 90 degrees

∠F + ∠ G + ∠H = 180

⇒ 9x - 1 + 90 + 3x + 7 = 180

⇒ 12x + 96 = 180

⇒ 12x = 180 - 96

⇒ 12x = 84

⇒ x = 84/12

⇒ x = 7

Therefore,

∠F = 9x - 1 = 9(7) - 1 = 63 - 1 = 62

And, ∠G = 90

And, ∠ H = 3x + 7 = 3(7) + 7 = 21 + 7 = 28

If we add the angles :

62 + 90 + 28 = 180°

Answer:

y = (-1/3)x + 3.

Step-by-step explanation:

To find the equation of a line perpendicular to a given line, we need to take the negative reciprocal of the slope of the given line.

The slope of the given line Y=3x-5 is 3. Therefore, the slope of a line perpendicular to this line would be -1/3.

Now, using the point-slope form of a line, we can write the equation of the line passing through (-9,6) and having a slope of -1/3:

y - 6 = (-1/3)(x - (-9))

Simplifying:

y - 6 = (-1/3)x - 3

y = (-1/3)x + 3
