keeping in mind that a year has 12 months, thus 3 months will just be 3/12 of a year, so

Find JKL and LKM if JKM = 140.

Answers

The measure of angles JKL and LKM are 100° and 40° respectively.

What is a supplementary angle?

A supplementary angle simply refers to two (2) angles or arc whose sum is equal to 180 degrees.

Additionally, the sum of all of the angles on a straight line is always equal to 180 degrees. In this scenario, we can logically deduce that the sum of angles JKL, LKM and JKM are not supplementary angles:

m∠JKL + m∠LKM = m∠JKM

Substituting the given parameters into the formula, we have;

4x° + (2x − 10)° = 140°

6x° − 10 = 140°

6x° = 140° + 10°

6x° = 150°

x° = 150/6

x = 25°

For angle JKL, we have:

m∠JKL = 4x

m∠JKL = 4(25)

m∠JKL = 100°.

For angle LKM, we have:

m∠LKM = 2x − 10

m∠LKM = 2(25) − 10

m∠LKM = 50 − 10

m∠LKM = 40°

C1 Determine the Greatest Common Factor of polynomials

Answers

To find the greatest common factor of a polynomial, find a number that all of its coefficients are divisible by, for example, the GCF of an 8x 2 + 4x + 2 is 2 because all of the coefficients (8, 4, 2) are divisible by 2 and the expression simplifies to 2(4x2 + 2x + 1).

What is the Greatest Common Factor?

A group of numbers' greatest common factor (GCF) is the biggest factor that all the numbers have in common. For instance, the numbers 12, 20, and 24 share the components 2 and 4. The GCF of 12, 20, and 24 is 4 because it is the largest.

To find the greatest common factor of a polynomial,  find a number that all the coefficients of the polynomial are divisible by i.e. the GCF of a 8x^2 + 4x + 2  is 2 because all the coefficients (8, 4, 2) are divisible by 2 and the expression simplifies to 2(4x^2 + 2x + 1).

The GCF can be smaller than the smallest coefficient, for example 20x^2 + 15x + 10 (GCF is 5, smallest coefficient is 10) and 5 < 10. However it cannot be larger than the smallest coefficient.

Therefore the smallest coefficient should be larger than or equal to the GCF in order to be divisible.

The probability of rolling dice twice

What is Probability?

The area of mathematics known as probability deals with numerical representations of the likelihood that an event will occur or that a statement is true. An event's probability is a number between 0 and 1, where, roughly speaking, 0 denotes the event's impossibility and 1 denotes certainty.

Total no. of outcomes = 6

The probability of getting a 1,2 or 3 from the first rolling is 3/6.

The probability of getting a 5 or 6 from second rolling is 2/6

As the two rollings are independent,

you can just multiply two probability values to come up with a final answer.

Which is,

             = (3/6) x (2/6)

             = (1/2) x (1/3)

             = (1/6)

The probability a rolling a 1, 2 or 3 on a number cube on your first roll, then a 5 or 6 the second roll is 1/6 or 0.16

Probability in % will be

                                   0.16 x  100/100

                                        = 16%

Hence, The probability a rolling a 1, 2 or 3 on a number cube on your first roll, then a 5 or 6 the second roll is 16%

What is volume?

Each thing in three dimensions takes up some space. The volume of this area is what is being measured. The space occupied within an object's borders in three dimensions is referred to as its volume.

For instance, a cup's capacity is stated to be 100 ml if it can hold 100 ml of water in its brim. The quantity of space occupied by a three-dimensional object can also be used to describe volume.

Group of answer choices

5 units

4 units

3 units

Answers

The length of A'B' = 5 units

The line segment AB is of 5 units. AB is then transformed through translation of 3 units to the right.

The translation only means change through a straight line. This transformation does not change the length of a line segment.

So the length of A'B' will also be 5 units.

But the position of A'B' will be different from that of AB on the co-ordinate plane. To be exactly, A'B' would be 3 units right to the position of AB on the co-ordinate plane.

Also the co-ordinates of A'B' will be different. Still their lengths will be same.

Thus the length of A'B' = 5 units

Answers

Answer:

$75.6

Explanation:

If the original cost was $70 and it was marked up 20%, the price after this is calculated as:

$70 + $70(0.2) = $70 + $14 = $84

Where $70(0.2) = $14 is the amount added to the original when it is marked up 20%.

Then, it was discounted 10%, we get that the selling price is

$84 - $84(0.1) = $84 - $8.4 = $75.6

Where $84(0.1) = $8.4 is the discount made on the initial price.

Therefore, the answer is $75.6

Therefore, the reciprocal of 7/3 is 3/7.

So, we can rewrite the division as:

9 ÷ (7/3) = 9 × (3/7)

To multiply fractions, we simply multiply the numerators together and the denominators together.

So, multiplying 9 and 3 gives us 27, and multiplying 7 and 1 gives us 7.

Therefore:

9 ÷ (7/3) = 27/7

The result, 27/7, is an improper fraction. It means we have 27 parts divided into 7 equal parts.

However, if you prefer, we can also express the result as a mixed number, which consists of a whole number and a proper fraction.

To convert 27/7 into a mixed number, we divide the numerator (27) by the denominator (7).

The quotient is the whole number part, and the remainder becomes the numerator of the proper fraction.

27 ÷ 7 = 3 remainder 6

So, the mixed number representation of 27/7 is:

27/7 = 3 6/7

Therefore, 9 divided by 7/3 is equal to 27/7 or 3 6/7.

Answer:

[tex]\frac{(x+3)(x-1)}{x}[/tex]

Step-by-step explanation:

So the first thing you want to do is factor out the polynomials.

[tex]x^2+4x+3 ; (x+3)(x+1)[/tex]

[tex]x^2+x; x(x+1)[/tex]

[tex]2x^2-3x+1; (2x-1)(x-1)[/tex]

Once you have factored these out, you can write out the division using keep-change-flip;

[tex]\frac{(x+3)(x+1)}{2x-1}*\frac{(2x-1)(x-1}{x(x+1)}[/tex]

Before trying to multiply all of the factors, rule out factors that appear both in the numerator and the denominator;

[tex]\frac{(x+3)}{1}*\frac{(x-1)}{x}[/tex]

Now you can multiply the fractions and receive [tex]\frac{(x+3)(x-1)}{x}[/tex]
