Answer:

9 gal

Step-by-step explanation:

Answer:

solution given;

length [l]=8in

breadth [b]=2in

height [h]=12in

we have

the surface area of the prism=2[lb+bh+lh]

=2[8×2+2×12+8×12]=272in²

272in² is your answer

Answer:

Impuesto= $10.5

Step-by-step explanation:

Dada la siguiente información:

El impuesto sobre ventas de un DVD, de $16.000 es $1.40.

Primero, debemos determinar la tasa porcentual del impiesto:

Tasa impositiva= 1.4/16= 0.0875 = 8.75%

Ahora, el impuesto sobre $120:

Impuesto= 120*0.0875

Impuesto= $10.5

Answer:

It is a rational number.

Step-by-step explanation:

Rational numbers can be represented as a ratio/fraction. So whole numbers are rational with a denominator of 1.

This number can be written as 177/100. It is rational.

Answer:

The amount to remove from each corner is a square, 4/3 ft by 4/3 ft.

Step-by-step explanation:

The piece of cardboard measures 8 ft by 8 ft.

Each corner will be cut to create the sides of the box.

Let the square cut from each corner measure x by x ft.

The base of the box will measure 8 - 2x by 8 - 2x, and the height of the box will be x.

V = (8 - 2x)^2 * x

V = 64x - 32x^2 + 4x^3

Now we differentiate and set the derivative equal to zero to find a maximum value.

64 - 64x + 12x^2 = 0

3x^2 - 16x + 16 = 0

(3x - 4)(x - 4) = 0

3x - 4 = 0  or  x - 4 = 0

3x = 4   or   x = 4

x = 4/3  or  x = 4

The solution x = 4 must be discarded since 8 - 2x = 8 - 8 = 0, and the sides would have 0 length.

The amount to remove from each corner is a square, 4/3 ft by 4/3 ft.

Explanation:

If we were to keep the red curve completely fixed, but we moved the xy axis four units to the left, then this would give the illusion the red curve is moving four units to the right to arrive at the blue curve's location.

Shifting the xy axis four units to the left is the same as subtracting 4 from each initial input x value. So we go from x to x-4.

The parent function f(x) = x^2 then becomes g(x) = (x-4)^2 which is choice C.

As one way to check, plug in x = 4 and you should find that g(4) = 0. This is the x intercept of the blue curve. Something like g(x) = (x+4)^2 does not work because plugging x = 4 into this leads to g(x) = 64, so that rules out choice A. You can eliminate choices B and D for similar reasoning as well.

Answer:

C.) G(x) = ( x-4 )^2

Answer:

x=4

Step-by-step explanation:

the ones on top of each other you are adding together so -10x + -2x equals -12x and -32+-16 equals -48 and -48 divided by -12x equals positive 4

Answer:

Step-by-step explanation:

you can see from the picture that adding 2y and -2y cancels out. So the remaining parts of the equations are

-10x=-32

-2x=-16

add the two together:

-12x=-48

x=4

Answer:

x > 9.

Step-by-step explanation:

Here it is just simplifying the inequality.

6 - 2/3x < x - 9

Add 2/3x to both sides.

6 < 5/3x - 9

Add 9 to both sides.

15 < 5/3x

Multiply by 3/5.

9 < x

Flip it.

x > 9.

Answer:

x > 9

Answer:

X = 64

Step-by-step explanation: The square in the corner indicates a 90 degree angle. by adding everything but X and subtracting that from 360 degrees we can get X. 180+90+26=296     360-296=64

Answer:

Step-by-step explanation:

We know that this need to total to 360°. Since we know this, it is simple and straight forward.

To find x, we need to add up all the known degrees.

180 + 90 + 26 = 296

Also if you do not know how I got 90, there is a right angle which is 90 degrees.

Now that we have the sum of the known degrees, we take that number and subtract that from 360

360 - 296 = 64

So our final answer is 64°

Should be 6^3.

Have a good day!

Step-by-step explanation:

Solution given;

cost price=Rs125

profit%=?

we have

profit%=[Selling price-cost price]/cost price×100%

=[selling price-Rs.125]/Rs 125×100% is your answer

Step-by-step explanation:

11.016cm^3  = 3.4 x 1.2 x H

3.4x1.2=4.08

11.016/4.08 = 2.7

11.016cm^3 = 3.4 x 1.2 x 2.7

Answer: Monica

Step-by-step explanation:

Given

Monica has a 20% chance of winning a prize

Brianne has a  [tex]\frac{1}{10}[/tex] chance of winning a prize

20% chance refers to

[tex]\dfrac{20}{100}=\dfrac{2}{10}[/tex]

As

[tex]\dfrac{2}{10}>\dfrac{1}{10}[/tex]

therefore, monica is more likely to win the prize.

Answer:

4

Step-by-step explanation:

The given equation of circle is:

[tex] (x+2)^2 +(y-3)^2 =4 [/tex]

[tex] (x+2)^2 +(y-3)^2 =2^2 [/tex]

Equating it with:

[tex] (x-h)^2 +(y-k)^2 =r^2 [/tex]

We find:

[tex] r^2=2^2 [/tex]

[tex]\therefore r=2 [/tex]

Radius of the circle = 2 units

Therefore,

Diameter of the circle = 2*2= 4 units

Answer:

1,920 words

Step-by-step explanation:

60 divided by 4 is 15

15 times 128 is 1,920.

Hope it helps! :)

Answer:

1920

Step-by-step explanation:

We know that it takes her 4 minutes to type 128 words

So we need to figure out how many it takes her to type a word per minute

128 divided by 4=32

So multiply 32 word by 60 ( 60 mins = an hour)

Answer=1920

Answer:

18

Step-by-step explanation:

Intersecting Secants Theorem:

6(x + 6) = 8(8 + 10)

6x + 36 = 8(18)

6x + 36 = 144

6x = 144 - 36

6x = 108

x = 18
