Answer:

The volume of the cube is $\mathit{\frac{27}{z^3x^{9}}}$ cu in.

Step-by-step explanation:

The Volume of a Cube

Let's have a cube of side length a. The volume of the cube is:

$V=a^3$

The cube of the image has a side length of

$\displaystyle a=\frac{3x^{-3}}{z}\ inches$

Simplifying the expression of the base by converting the negative exponent in the numerator to the denominator:

$\displaystyle a=\frac{3}{zx^{3}}\ inches$

Now find the volume:

$\displaystyle V=\left(\frac{3}{zx^{3}}\ inches\right)^3$

Applying the exponents:

$\displaystyle V=\frac{3^3}{z^3x^{9}}\ inches^3$

$\displaystyle V=\frac{27}{z^3x^{9}}\ inches^3$

The volume of the cube is $\mathbf{\frac{27}{z^3x^{9}}}$ cu in.

Drag each expression to show whether it is equivalent to

Kazeer [188]

Answer:

We need to find which expressions are equivalent to $6(c+6)$ , $6c+6$ or neither.

$6c+12$ : We extract the greatest common factor which is 6. Remember, when we extract a GCM, we divide each term by it.

$6c+12=+(c+2)$

Therefore, this expression is equivalent to neither of the given expressions.

$2(3c+3)$ : We just need to apply the distributive property.

$2(3c+3)=6c+6$

Therefore, this expression is equivalen to $6c+6$ .

We use the same process to the other expressions.

$(6c)+(6\times 6)=6c+36=6(c+6)$

$3c+6+3c=6c+6$

$6c+36=6(c+6)$

$(6+c)+(6+6)=c+18$ , equivalent to neither.

In the diagram below, GH is parallel to DE . If GH is 3 more than EH FH=10, and DE=12 find the length of EH. Figures are not nec

steposvetlana [31]

Answer: 5

Step-by-step explanation:

Since $\overline{GH} \parallel \overline{DE}$ , by the corresponding angles theorem, $\angle FGH \cong \angle FDE, \angle FHG \cong \angle FED$ . This means $\triangle FGH \sim \triangle FDE$ by AA.

As corresponding sides of similar triangles are proportional,

$\frac{10}{x+3}=\frac{10+x}{12}\\(10)(12)=(10+x)(x+3)\\120=x^{2}+13x+30\\x^{2}+13x-90=0\\(x+18)(x-5)=0\\x=-18, 5$
However, as distance must be positive, we consider the positive solution, x=5.

Therefore, the answer is 5

Could someone please help me with this question??

Answer: 26 cups will fit in a dispenser that is 30 cm high.

Step-by-step explanation:

First of all, we know that the first cup in the stack (the bottom cup) will be ten centimeters high, and we know that for every cup that is added on top of that, .8 centimeter will be added to the height. So, if we want to find how many cups will be in the dispenser we do this simple math:

30 - 10 = 20 Because the first cup is ten centimeters, we have to subtract that from the dispenser height.

20/.8=25 To find how many cups will be stacked on top of the first cup, we divide the remaining height by .8, the height of every other cup.

Now that we know that there will be 25 cups stacked on top of the first, we add the bottom cup to the rest of them.

25 + 1 = 26 Cups.
