Answer:

[tex]\mid x-6 \mid \geq 0[/tex]

Step-by-step explanation:

We have two options for x; it is either 6 or greater than 6:

If [tex]x=6\\[/tex], [tex]\mid x-6 \mid = \mid 6-6 \mid = \mid 0 \mid = 0\\[/tex].

If [tex]x > 6[/tex], [tex]\mid x-6 \mid > \mid 6-6 \mid[/tex] => [tex]\mid x-6 \mid > 0[/tex].

(for example, if [tex]x=7\\[/tex], [tex]\mid x-6 \mid = \mid 7-6 \mid = \mid 1 \mid = 1 > 0[/tex])

So, [tex]\mid x-6 \mid = 0[/tex] or [tex]\mid x-6 \mid > 0[/tex]; [tex]\mid x-6 \mid \geq 0[/tex].

Answer:

  D.  72sin(α)cos(α)

Step-by-step explanation:

Given two sides and the angle between, the area of a triangle can be found from the formula ...

  Area = (1/2)ab·sin(C)

Here, that translates to ...

  Area = (1/2)(12)(y)sin(α)

Using the trig relation ...

  Cos = Adjacent/Hypotenuse

we can find y:

  cos(α) = y/12

  y = 12·cos(α)

__

Substituting this into the area calculation above, we have ...

  Area = (1/2)(12)(12·cos(α))sin(α)

  Area = 72sin(α)cos(α)

Answer:

The area of the figure is 49.12ft² (nearest hundredth)

Step-by-step explanation:

The area of the figure is the sum of the areas of the right triangle and semi circle that make up the figure.

Note that the radius of a circle is twice its diameter

That means, the radius of the semi-circle is 4 feet

Area of the triangle = 1/2 x Base X Height = 1/2 x 6 ft x 8 ft =24 ft²

Area of the semi circle = 1/2 πr² = 1/2 x 3.14 x 4² = 25.12 ft²

Hence, the area of the figure is:

24 ft² + 25.12 ft² = 49.12 ft²

Answer:

20y + 36

Step-by-step explanation:

Distribute the 4 to everything in the parenthesis (multiply).

4 x 5y = 20y

4 x 9 = 36

The solution of the expression 4(5y + 9 ) will be 20y + 36. The correct option is C.

Expression in maths is defined as the collection of numbers variables and functions by using signs like addition, subtraction, multiplication, and division.

Numbers (constants), variables, operations, functions, brackets, punctuation, and grouping can all be represented by mathematical symbols, which can also be used to indicate the logical syntax's order of operations and other features.

The expression 4(5y+9) will be solved as below:-

E = 4 ( 5y+9 )

E = 20 y + 36

Therefore, the solution of the expression 4(5y + 9 ) will be 20y + 36. The correct option is C.

Answer:

2/5

Step-by-step explanation:

40% as a fraction is 4/10, when this fraction is simplified, it ends up as 2/5.

The  probability of the event that Diya's chance of wining the game is 0.4 or 2/5.

The probability of an event is the chance of happening that particular event.

Let, Diya can play a game 100 times.

Therefore, the number of times she can win the game is 40.

Let, D = the event that Diya is participating in the game.

Therefore, the probability that Diya will win the game is

Answer:

Step-by-step explanation:

You need to find the HCF of 36 and 90.

Prime factors of each:

HCF includes all prime factors of both numbers:

To find the least number,

Which is exactly divisible by 36 and 90. We have to find the HCF of 36 and 90.

→ 36 = 2 × 2 × 3 × 3

→ 90 = 2 × 3 × 3 × 5

Then the required HCF will be,

→ 2 × 2 × 3 × 3 × 5

→ 180 (HCF)

Thus, 180 is the least number which is exactly divisible by 36 and 90.

[tex] t= 50 + \frac{n - 4}{4} [/tex]

switch sides

[tex]50 + \frac{n - 4}{4} = t[/tex]

subtract 50 from both sides

[tex]50 + \frac{n - 4}{4} - 50 = t - 50[/tex]

simplify

[tex] \frac{n - 4}{4} = t - 50[/tex]

simplify

[tex] \frac{n - 4}{4} = t - 50[/tex]

multiply both sides by 4

[tex]4 \frac{(n - 4)}{4} = 4t - 4 \times 50[/tex]

simplify

[tex]n - 4 = 4t - 200[/tex]

add 4 both sides

[tex]n - 4 + 4 = 4t - 200 + 4[/tex]
