Figure A is a scale image of figure B. Figure A maps to figure BBB with a scale factor of 2/7. What is the value of x?

Answer:

Step-by-step explanation:

the volume of this prism is equal to

V=l*w*h

V=(x+1)(x)(x-3)

multiply

V=x^3-2x^2-3x

it is your first choice

Answer:

Step-by-step explanation:

[tex]V=LWH\\ \\ V=x(x+1)(x-3)\\ \\ V=x(x^2-2x-3)\\ \\ V=x^3-2x^2-3x[/tex]

12 and 8

Step-by-step explanation:

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.

Answer:

  2.25

Step-by-step explanation:

Add the square of half the x-coefficient to complete the square.

  (-3/2)² = 9/4 = 2.25

Answer: 0.25g<2.50.... g<10

Step-by-step explanation: Let us say that the number of gumballs bought is represented by the variable g. In this case, the question is asking how many gumballs can be bought without surpassing the price of $2.50. We know that each gumball is $0.25, therefore the number of gumballs we buy times $0.25 has to be less than $2.50. Hence, the inequality would be 0.25g<2.50. If we were to solve this then g<2.50/0.25-----> g<10. In conclusion, the number of gumballs you can buy has to be less than 10. Thank you!

Answer:

74

Step-by-step explanation:

Please separate the two functions:

g = -7.1

h = 3 - 10g

Substitute -7.1 for g in h = 3 - 10g:

h = 3 - 10(-7.1) = 71 + 3 = 74

I'm not sure about answer...

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.

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

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]

Answer:

20

Step-by-step explanation:

Answer:

48

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.

There are other methods of solving this but I think this is the easiest way!

Answer:

33.3333333% (with the 3 repeating forever)

Step-by-step explanation:

If they sell 16 pounds/48 pounds, you can first simplify this fraction:

16/48 = 1/3.

Then, you do 1 divided by 3 and you would get 0.33333...

As a percent, this is 33.3% (where the 3 is repeating forever)
