Caroline claims that it is likely, but not certain, that she will win the game on her next spin.

Explain why Caroline's claim is not correct.

Answers

Umm i don’t know hopefully you can find someone to answer this for you

Answer:

It’s x+8 at the bottom but if you solve this please give me a step by step so I know how to solve it, thank you!!♥️

Answers

Answer:

x=4.

Step-by-step explanation:

Let's solve your equation step-by-step.

5/15=x/ x+8

Step 1: Cross-multiply.

5/15=x/ x+8

5*(x+8)=x*(15)

5x+40=15x

Step 2: Subtract 15x from both sides.

5x+40−15x=15x−15x

−10x+40=0

Step 3: Subtract 40 from both sides.

−10x+40−40=0−40

−10x=−40

Step 4: Divide both sides by -10.

−10x−10=−40−10

Then your answer will be x=4.

An open box is to be made by using a piece of sheet metal with the dimensions of 4m by 2m. Determine the dimensions the box should be to maximize volume by cutting out the four corners of the material and folding up the edges to make the box. The material that is cut out is waste and cannot be used.

Answers

Answer:

Dimensions: 0.4 by 3.2 by 1.2

Step-by-step explanation:

I'm assuming here that we are cutting out squares out of each of the metal's corners:

Let x = the length of each cut-out square,

Each base (of the desired net square folded) is 4-2x, and 2-2x respectively,

Volume = x(4-2x)(2-2x)

             = 4x^3 - 12x + 8x

Now we take the derivative:

[tex]\frac{d}{dx}\left[4x^3-12x^2+8x\right]\\\\= \frac{d}{dx}\left(4x^3\right)-\frac{d}{dx}\left(12x^2\right)+\frac{d}{dx}\left(8x\right)\\\\= 12x^2-24x+8[/tex]

We equate to 0 (0 for max volume), and solve using the quadratic formula:

[tex]12x^2-24x+8=0,\\\\x_{1,\:2}=\frac{-\left(-24\right)\pm \sqrt{\left(-24\right)^2-4\cdot \:12\cdot \:8}}{2\cdot \:12}\\\\= \frac{-\left(-24\right)\pm \:8\sqrt{3}}{2\cdot \:12}\\\\\mathrm{Separate\:the\:solutions}:\\\\x_1=\frac{-\left(-24\right)+8\sqrt{3}}{2\cdot \:12},\:x_2=\frac{-\left(-24\right)-8\sqrt{3}}{2\cdot \:12}\\\\x =\frac{3+\sqrt{3}}{3},\:x=\frac{3-\sqrt{3}}{3}\\\\x=1.57735\dots ,\:x=0.42264\dots[/tex]

So we approximate the side lengths to be 1.6 and 0.4 respectively. But when we plug in 1.6 for x, we get the volume as negative. Therefore x has to be 0.4.

Side lengths: 0.4, 4-2(0.4) => 3.2, 2-2(0.4) => 1.2

The width of a circular track is 2 meters. If the radius of the outer circle is 6 meters, find the area of the track.​

Answers

Answer:

[tex] 62.8 \: {m}^{2} [/tex]

Step-by-step explanation:

Radius of outer circle = 6 m

Width of the track = 2 m

So, radius of inner circle = 6 - 2 = 4 m

Area of the track = Area of outer circle - Area of inner circle

[tex] = \pi {6}^{2} - \pi {4}^{2} \\ \\ = \pi( {6}^{2} - {4}^{2} ) \\ \\ = 3.14 \times (36 - 16) \\ \\ = 3.14 \times 20 \\ \\ = 62.8 \: {m}^{2} [/tex]

which images shows a reflection​

Answers

I'll Give You Some Hints:

Let's Look at C.

In C, the triangle is translated 2 units to the right. Which means that it cannot be a reflection.

Let's Look at B.

In B there is a sideways triangle. That means it's a Rotation. Which means it's not Reflected.

Lastly, Let's Look at A.

To get from the original triangle to the triangle in A, you have to reflect twice. Once along a vertical line, and then along a horizontal line.

Option A is the correct answer.

What are corresponding angles?

The angles that are in the same position on a given two parallel lines intersected by a transversal line are called the corresponding angles.

Corresponding angles are always equal.

We can also have alternate angles which are always equal.

We can also have alternate interior and exterior angles which are equal.

The angles on the same side make upto 180 degrees

We have,

From the figure,

We can see that,

(2x - 20) and (x + 15) are opposite angles.

So,

2x - 20 = x + 15

2x - x = 15 + 20

x = 35

Thus,

The measure of angle ∠MHJ is 35.

To start you will find the area as if it was a rectangle. To do that you have to do 8x12. 8x12 = 96, but to find the area of a triangle you take the area of the rectangle and divide it by 2. 96 divided by 2 is equal to 48.

Is that right? Is x equal to 6?

Answers

Answer:

x=4

Step-by-step explanation:

It can't be x=6 because 15x6 is 90 and that doesn't allow for the 8x-2. The bottom half has to equal 180 because it's a straight line. So, 18x4=60. Then 8(4)-2 equals 30. 30+60=90. 90+90 equals 180.
