3 *9 x^12

The 3's cancel  and we know a^b/ a^c = a^(b-c)

100/9 x^ (8-12)

100/9 x^-4

sqrt( 100/9 x^-4)

Put the negative exponent in the denominator and make it positive

sqrt( 100 / (9x^4) )

We know that sqrt( a / b) = sqrt(a) / sqrt( b)

sqrt(100)

Commutative property of addition.

EXPLANATION

Let a,b be real numbers. The commutative property of addition states that,

[tex]a + b = b + a[/tex]

If we let a=-10 and b=6, then

[tex]-10+6=6+(-10)[/tex]

Therefore the given expression demonstrates the commutative property of addition.

The commutative property of addition tells us that, the order in which we add two real numbers does not affect the result.

[tex]\bf tan(39^o)=\cfrac{\stackrel{opposite}{x}}{\stackrel{adjacent}{8}}\implies 8\cdot tan(39^o)=x\implies 6.48\approx x \\\\[-0.35em] ~\dotfill\\\\ \cfrac{sin(39^o)}{x}=\cfrac{sin(51^o)}{8}\implies \cfrac{8\cdot sin(39^o)}{sin(51^o)}=x\implies 6.48\approx x[/tex]

one thing to bear in mind is that calculators have two modes, Degree mode and Radian mode, if your calculator is in Radian mode and you plug in tan(39), it thinks "tangent of 39 radians" and so it gives that, bearing in mind that 1 radian is about 57°.

So make if you're using degrees as the angle, make sure your calculator is in Degree mode first, thus tan(39) will mean "tangent of 39 degrees".

The volume of the sphere is 2304π cubic units or 7238.229 cubic units if the radius is 12 units.

It is defined as three-dimensional geometry when half-circle two-dimensional geometry is revolved around the diameter of the sphere that will form.

[tex]\rm V = \dfrac{4}{3} \pi r^3[/tex]

We have a radius of the sphere R = 12 units

Volume:

[tex]\rm V = \dfrac{4}{3} \pi (12)^3[/tex]

V = 2304π cubic units or

V = 7238.229 cubic units

Thus, the volume of the sphere is 2304π cubic units or 7238.229 cubic units if the radius is 12 units.

Charlie should divide the 15 cents into four bags with 1 cent, 2 cents, 4 cents, and 7 cents respectively. Using combinations of these bags, he can pay any amount between 1 cent and 15 cents without opening them.

The question asks us to figure out how Charlie can divide 15 cents among four small bags so he can use these bags to pay any amount between 1 cent and 15 cents without opening them.

To solve this, we need to think about the binary representation of numbers, because each bag can either be used or not used in each transaction, similar to how a binary '1' or '0' can represent 'on' or 'off'.

Therefore, he should put the amounts that correspond to the powers of 2 in three of the bags: 1 cent, 2 cents, and 4 cents, and in the last bag, we put the sum of these three, which is 7 cents.

This way, he can make any amount up to 15 cents:

bearing in mind that a diagonal line from the center of a square will give us an isosceles triangle, Check the picture below.

Answer:

The area of this polygon is 98.1 yd²

Step-by-step explanation:

Check the image below.

The diagonal line from the corner of a square to the center of this one will shape an isosceles triangle.

The Pythagoras theorem give us the following formula:

A² + A² = H²

Both "A" are the sides and H is the hypotenuse, seeing the figure, the diagonal coincide with the hypotenuse and the measure is 7 yd.

A² + A² = 72  

2A² = 49

A²= 49/2

A²= 24. 5

A=√24.5

A= 4.95 yd

Knowing that the diagonal ends up in the center of the square, we assume that the side of the triangle (“A” side) is the half of the side of the square, then this last one is 2A. Bearing in mind that square have all of the sides with the same measure, the four sides have a 2A size.

2A = 2(4.95) =9.9 yd

Each side of the square measures 9.9 yd

The area of a square is  

Side²= (2A)2²

(9.9)²= 98.1 yd²

The area of this polygon is 98.1 yd²

A. X=0 Y=5

Those 2 equations are a system. You answer is the value of x and y.

13x+3y=15

y=5-4x

First, lets make each equation fit into y=mx+b

13x +3y=15 y=5-4x

-13x -13x y=-4x+5

3y= -13x +15

Let's use the elimination method to solve this.

y= -4x+ 5 multiply top by 3

3y=-13x+15

3y=-12x+15

3y=-13x+15 subtract the equations

Step-by-step explanation:

A triangular prism has three rectangular sides and two triangular faces. To find the area of the rectangular sides, use the formula A = lw, where A = area, l = length, and h = height. To find the area of the triangular faces, use the formula A = 1/2bh, where A = area, b = base, and h = height.

Answer:

The volume is 36 inches cubed.

Step-by-step explanation:

The volume of a rectangular prism is W*L*H.

You are given the H=3i, W=2 in, and L=6 in.

So now we plug into our formula for the volume of a rectangular prism which will result in 2*6*3=12*3=36.

The volume is 36 inches cubed.

Answer: [tex]36\ in^3[/tex]

Step-by-step explanation:

The volume of a rectangular prism can be calculated with this formula:

[tex]V=lwh[/tex]

Where "l" is the lenght, "w" is the width and "h" is the height.

In this case we know that this rectangular solid is 3 inches high, 6 inches long and 2 inches wide. Then:

[tex]h=3\ in\\l=6\ in\\w=2\ in[/tex]

Then, substituting these values into the formula, we get that its volume is:

To determine the number of red and green apples Natasha could have, we need to consider the given information. Natasha has a total of 13 apples, and she has more red apples than green apples.

Let's assume that Natasha has r red apples and g green apples. We know that r + g = 13, since she has a total of 13 apples.

Given that she has more red apples than green apples, we can say that r > g.

Now, we need to find the possible values of r and g that satisfy these conditions. We can use trial and error to find the values that work:

Based on our analysis, Natasha could have either 9 red apples and 4 green apples, or 10 red apples and 3 green apples.
