In triangle IJK , O is the intersection of the three medians . If IN = 12 find IK. please help

solution of the equation is: (1, 6 ). This can be solved by substitution method.

The meaning of such an equations in algebra is just a mathematical expression stating the equality between two mathematical terms. For instance, 6x + 5 = 11 is an equation where 6x + 5 and 11 are two expressions separated by the 'equal' sign.

Identity equations and conditional equations are the two types of equations. For just any value of both the variables, an equality remains true. Only such variables have values that make a condition expression true. Two expressions joined by an equals sign ("=") form an equation.

y = 5x + 1 .............(1)

4x + y = 10 ............ (2)

substitute y = 5x + 1 into (2)

4x + 5x + 1 = 10

or, 9x + 1 = 10 ( subtract 1 from both sides )

or, 9x = 9 ( divide both sides by 9 )

or, x = 1

substitute x = 1 into (1)

y = 5(1) + 1

or, y = 5 + 1

or, y = 6

Thus, solution of the equation is: (1, 6 )

Answer: 45%

Step-by-step explanation: Do 9 over 20. 9/20. Then compare to 100. (100 is on the bottom.) 20 x 5 = 100.    Do the same for the top.   9 x 5 = 45%

The meaning of the y-intercept in this situation is that: A) When the cab travels 0 miles, the total fee will be $14.00.

Mathematically, the point-slope form of a straight line can be calculated by using this mathematical expression:

y - y₁ = m(x - x₁) or y - y₁ = (y₂ - y₁)/(x₂ - x₁)(x - x₁)

Where:

Next, we would determine the linear equation representing the line and passes through the points (2, 17) and (5, 21.5) by using the point-slope form as follows:

y - y₁ = m(x - x₁)

y - y₁ = (y₂ - y₁)/(x₂ - x₁)(x - x₁)

y - 17 = (21.5 - 17)/(5 - 2)(x - 2)

y - 17 = 4.5/3(x - 2)

y - 17 = 1.5(x - 2)

y = 1.5x - 3 + 17

y = 1.5x + 14

Therefore, the y-intercept is equal to 14.

Appreciation is an increase in the value of an asset over time. The term is widely used in several disciplines, including economics, finance, and accounting.

The easiest technique to calculate home appreciation is to divide the increase in value by the starting cost and multiply by 100 to get the difference as a percentage.

Final value minus initial value equals monetary change.

(Value change / initial investment) 100 represents the appreciation %.

1.0  N rate of appreciation)

2.0 N years equals the appreciation factor.

Answer:

a) 40cm²

b) 150cm²

Step-by-step explanation:

a)

The area of the shaded region is equal to the area of the larger rectangle, minus the area of the smaller rectangle.

Knowing the formula for the area of a rectangle is bh (where b is base and h is height), we can find

Large rectangle area: bh = (20)(10) = 200cm²

Smaller rectangle area: bh = (12)(10) = 120cm²

The area of the shaded region is therefore 200-120cm²=80cm²

b)

The area of the shaded region is equal to the area of the larger triangle, minus the area of the smaller triangle.

Knowing the formula for the area of a triangle is 0.5bh (where b is base and h is perpendicular height), we can find

Large triangle area: 0.5bh = 0.5(20)(20) = 10(20) = 200cm²

Smaller triangle area: 0.5bh = 0.5(20)(5) = 10(5) = 50cm²

The area of the shaded region is therefore 200-50cm²=150cm²

Answer:a) 140 cm^

b)150m^2

Step-by-step explanation:

a)first find the area of big rectangle i.e rectangle

area of rectangle 1 = length ×breadth

area of rectangle = 10×20=200cm^2

now find area of small rectangle i e rectangle

area of rectangle 2 = 12×5=60cm^2

now subtract area of rectangle 2 from area of rectangle

area of shaded portion =200-60= 140cm^2

b)find area of big triangle i.e triangle 1....

area of triangle 1 = 1/2 × base × height...

area of triangle 1 =1/2×20×20 = 200m^2

area of triangle 2 =1/2×10×5 =25m^2

area of triangle 3=1/2×10×5= 25m^2

area of shaded portion = area of triangle 1 - area of triangle 2 - area of triangle

area of shaded portion =200-25-25 =150m^2

According to the given information in the question P(A) is mutually exclusive.

When two events are incompatible with one another, the specific addition rule is applicable in probability. It claims that the likelihood of either event happening is equal to the likelihood of each event happening individually. If two occurrences A and B are considered to be mutually exclusive, then P(A) + P(B) is the formula used to determine the likelihood that either event will occur (B).

Assuming that event A and event B are mutually exclusive event.

To prove: Aand B are mutually exclusive.

Answer: a = 7, b = -4:

This equation can be rewritten as 7x = ax + b - 4.

Since the coefficients of x on both sides are equal, the equation becomes 7x = ax - 4, we can see that the equation has only one solution.

a = 4, b = 7:

This equation can be rewritten as 7x = ax + b - 7.

Since the coefficients of x on both sides are different, the equation becomes 7x = 4x + 7, we can see that the equation has no solution.

a = 7, b = 4:

This equation can be rewritten as 7x = ax + b - 4.

Since the coefficients of x on both sides are equal, the equation becomes 7x = 7x + 4, we can see that the equation has infinitely many solutions.

The two transformation that would map triangle ABC onto triangle A'B'C' include the following:

In Geometry, dilation is a type of transformation which typically changes the size of a geometric object, but not its shape.

Next, we would have TO apply a dilation to the coordinates of the preimage by using a scale factor of 1/2 centered at the origin as follows:

Ordered pair A (-2, 2) → Ordered pair A' (-2 × 1/2, 2 × 1/2) = Ordered pair A' (-1, 1).

Ordered pair B (-4, 2) → Ordered pair B' (-4 × 1/2, 2 × 1/2) = Ordered pair B' (-2, 1).

Ordered pair C (-4, 4) → Ordered pair C' (-4 × 1/2, 4 × 1/2) = Ordered pair C' (-2, 2).

Furthermore, by applying a reflection over the y-axis to the coordinates of triangle A'B'C', the image coordinates include the following:

(x, y)                               →              (-x, y)

Ordered pair A' (-1, 1)    →    Ordered pair A'  (-(-1), 1) = (1, 1).

Step-by-step explanation:

Usually when you times a fraction by 2 (both the top and the bottom number are timed by the same number) you can get the closest fraction.

The value of q in the arithmetic sequence is 1/2

An arithmetic sequence is a sequence where each term increases by adding/subtracting some constant k. This is in contrast to a geometric sequence where each term increases by dividing/multiplying some constant k. Example: a1 = 25. a(n) = a(n-1) + 5.

The common difference of arithmetic sequence is found by subtract subtracting the first from the second term. This means

d = 2q+2 - q = q+2

the sum of term is a(n) = a +( n-1)d

for third term it will be a(3) = q+ (3-1) q+2

a(3) = q +2(q+2)

the third term = 5q+ 3

5q+3 = q+ 2q+4 = 3q+4

5q+3 = 3q+4

collect like terms

5q-3q = 4-3

2q = 1

q = 1/2

therefore the value of q = 1/2

The required measure of m ∠Q is 46 degrees for the given figure.

When two lines intersect at a location, vertical angles are generated. They are always equal to each other.

As per the corresponding angles property, we can write the equation would be as:

17x = 56 + (8x-2)

17x - 8x = 56 - 2

9x = 54

x = 6

Since m ∠Q = 8x-2

So substitute the value of x = 6 in the above equation,

Then, we get m ∠Q = 8(6) - 2 = 46 degree

Thus, the required measure of m ∠Q is 46 degrees.

The equation relating temperature and time is given by 3y = -10x + 130

The equation of a line is expressed as y = mx + b where m is the slope and b is the y-intercept

And y - y₁ = m ( x - x₁ )

y = y-coordinate of second point

y₁ = y-coordinate of point one

m = slope

x = x-coordinate of second point

x₁ = x-coordinate of point one

The slope m = ( y₂ - y₁ ) / ( x₂ - x₁ )

Given data ,

Let the temperature be represented as y

Let the time be represented as x

Now , let the first point be P = P ( 1 , 40 )

Let the second point be represented as Q = Q ( 7 , 20 )

The slope of the line between the points m = ( y₂ - y₁ ) / ( x₂ - x₁ )

Substituting the values in the equation , we get

Slope m = ( 40 - 20 ) / ( 1 - 7 )

On simplifying the equation , we get

Slope m = -20/6

Slope m = -10/3

Now , the equation of line is y - y₁ = m ( x - x₁ )

Substituting the values in the equation , we get

y - 40 = ( -10/3 ) ( x - 1 )

On simplifying the equation , we get

y - 40 = ( -10/3 )x + 10/3

Adding 40 on both sides of the equation , we get

y = ( -10/3 )x + 130/3

Multiply by 3 on both sides of the equation , we get

3y = -10x + 130

when x = 1 am

3y = -10 + 130

3y = 120

y = 40 degrees

when x = 7am

3y = -70 + 130

3y = 60

y = 20 degrees

Hence , equation representing temperature and time is 3y = -10x + 130
