There are 288  outcomes are created by rolling a 4-sided die, 6-sided die, and a 12-sided die at the same time.

A combination is a mathematical technique that determines the number of possible arrangements in a collection of items where the order of the selection does not matter.

The outcomes are created by rolling a 4-sided die, 6-sided die, and a 12-sided die at the same time.

The number of  outcomes is created by rolling a 4-sided die, 6-sided die, and a 12-sided die at the same time is;

[tex]\rm Outcome=4\times 6\times 12\\\\Outcomes =288[/tex]

Hence, there are 288  outcomes are created by rolling a 4-sided die, 6-sided die, and a 12-sided die at the same time.

Answer:

[tex]-13x-23[/tex]

Step-by-step explanation:

Given sequence:  [tex]x-9, -x-11, -3x-13[/tex]

Therefore,

General form of an arithmetic sequence: [tex]a_n=a+(n-1)d[/tex]

(where a is the first term and d is the common difference)

To find the common difference, subtract a term from the next term:

[tex]\begin{aligned}d & =a_2-a_1\\ & =(-x-11)-(x-9)\\ & = -x-11-x+9\\ & = -2x-2\end{aligned}[/tex]

Therefore,

[tex]a_n & =(x-9)+(n-1)(-2x-2)[/tex]

To find the 6th term, input n = 6 into the equation:

[tex]\begin{aligned}\implies a_6 & =(x-9)+(6-1)(-2x-2)\\ & = (x-9)+7(-2x-2)\\ & = x-9-14x-14\\ & = -13x-23\end{aligned}[/tex]

Answer:

31.4 m

Step-by-step explanation:

The formula for the circumference of a circle is c=dπ, so we can substitute our diameter and 3.14 for pi.
c=(10)(3.14)

c=31.4

So the diameter is 31.4 meters.

Answer:

Area: 10.7521 cm

Circumference: 11.62389 cm

________________________________________________________

Area, A, will equal the formula of [tex]\pi r^2[/tex], so we must find the value and split that up. Diameter, d is equal to 2r. Let's solve.

[tex]A = \pi r^2[/tex]

[tex]d = 2r[/tex]

Now, make an equation combining like terms.

[tex]A = \frac{1}{4} \pi d^2[/tex]

This equation means to multiply those terms together. Since the diameter is 3.7, d is 3.7

[tex]\frac{1}{4} * \pi * 3.7 = 10.8(estimate)~cm[/tex]

Let's move on to circumference. On we go!

________________________________________________________

With circumference, it is very similar to what you just did to find area(A). You must again, set up these terms and make an equation out of them. C(circumference) is going to be equal to [tex]\pi r[/tex], notice how it does not say squared([tex]^2[/tex]) at the end now.

[tex]C = \pi r[/tex]

And diameter, you guessed it, will be 2r.

[tex]d = 2r[/tex]

Now, combine the like terms into an equation.

[tex]C = \pi d[/tex] pi times diameter(3.7)

[tex]\pi * d(3.7) = 11.6~cm[/tex]

Now that the problem is done, we move on to review.

________________________________________________________

We learned how to solve for circumference and area using diameter.

Answer:

43cm²

Step-by-step explanation:

let's first consider the area of a square.

the area is L² which means all sides are equal so we take the length times the breadth which is both equal because like we said all sides are equal.

so to find the side of the square using the area, we take the square root of both of the area.

[tex] \sqrt{25} = 5[/tex]

and also

[tex] \sqrt{18} = 4.2[/tex]

so we have the height of the triangle as 5cm and the base is 4.2cm.

now, from the triangle, since we have two sides and it's a right-angled, we can use Pythagoras' formula.

[tex] \sqrt{ {5}^{2} + {4.2}^{2} } = 6.53cm[/tex]

so the side 6.53cm is also the same side as the largest triangle. Since it's a square, all sides are equal. So we find the area of the largest triangle by using the formula

Area = L²

Area = 6.53²

Area = 42.6cm

the nearest cm square

Area = 43cm²
