Supplementary because it's just like complementary angles except supplementary adds up to 180 degrees. Often you will see supplementary angles created in a ray shoots out from a flat line. For example

They are all supplementary to each other because supplementary means that they all add up to 180

A man is four times as old as his son. In 3 years, the father will be three times as old as the son. How old is each now?

aivan3 [116]

The man is 27 years old and the son is 9 years old.

We can write the son's age as 'x', and therefore write the man's age as 4x. In 3 years, both their ages will increase by 3, so the son's age is now x + 3, and the man's age is 4x + 3.

We are told that the man is now 3 times older than his son, which means his current age, 4x + 3, is the same as 3 times the son's current age, which is x + 3.

Therefore we can write an equation:

4x + 3 = 3(x + 3)

4x + 3 = 3x + 9

- 3x

x + 3 = 9

- 3

x = 6

We can now substitute this in to find their current ages:

Son's age = x + 3 = 6 + 3 = 9

Man's age = 4x + 3 = 24 + 3 = 27

I hope this helps! Let me know if you have any questions :)

ICE Princess25 [194]

Answer:

The dimensions of the room is 8 feet × 12 feet.

Step-by-step explanation:

The area of the house, A = 96 ft²

The link is 12 feet less than three times the width of the room .

Let the width of the room is x.

Length = 3x-12 ...(1)

The area of a rectangular room is given by :

A = lb

96 = (3x-12)x

$3x^2-12x-96=0\\\\x^2-4x-32=0\\\\x^2-8x+4x-32=0\\\\x(x-8)+4(x-8)\\\\(x+4)(x-8)=0\\\\x=-4,8$

Neglecting negative value, width = 8 feet

Put x = 8 in equation (1)

Length = 3(8) - 12

= 12 feet

Hence, the dimensions of the room is 8 feet × 12 feet.

The PMF of $X$ is almost geometric in nature. Let $p=\frac{11}{29}$ . Then

$P(X = x) = \begin{cases} p & \text{if }x = 0 \\ (1-p)p & \text{if }x = 1 \\ (1-p)^2 p & \text{if }x = 2 \\ (1-p)^3p & \text{if }x = 3 \\ (1-p)^4 & \text{if }x = 4 \\ 0 & \text{otherwise}\end{cases}$
