Answer:

volume is 540 inches^3

Step-by-step explanation:

The computation of the volume of the full sized solid is given below:

The length would be

[tex]\frac{a}{3}, \frac{b}{3}, \frac{c}{3}[/tex]

And, the volume is

[tex]\frac{a}{3} \times \frac{b}{3} \times \frac{c}{3}[/tex]

As the volume is given 20 cubic inches

So,

[tex]\frac{abc}{27} = 20\\\\abc = 540 inches^3[/tex]

hence, volume is 540 inches^3

Answer:

25. [tex]27a^{3}b^{2}[/tex]

26. [tex]3\pi x^{3}y[/tex]

Step-by-step explanation:

For 25:

[tex]A = \frac{a+b}{2} h[/tex]  (area of a trapezoid)

[tex]A=\frac{11a^{2}b+7a^{2}b}{2} *3ab[/tex]  (substitute terms)

[tex]= \frac{18a^{2}b}{2}*3ab[/tex]  (collect like terms)

[tex]= 9a^{2}b*3ab[/tex]  (reduce the fraction by crossing out 2)

[tex]= 27a^{3}b^{2}[/tex]  (calculate)

For 26:

[tex]A=\pi r^{2}[/tex]  (equation of area of a circle)

[tex]A=\pi (3x^{3} y)^{2}[/tex]  (enter the radius)

[tex]= 3\pi x^{3} y[/tex]  (communtative property to reorder the terms)

Answer:

ok if you are asking for "what is x" your answer would be 7

Step-by-step explanation:

so first what I did was add the the tree to the 11 to get fourteen then i thought hmm what times 2 equals fourteen and boom I got my answer of seven

Answer:

x = 7

Step-by-step explanation:

2x - 3=11

collect like terms

11+3=2x

14 = 2x

divide both sides by 2

14/2 = 2x/2

7 = x

Answer:

x = 9

y = 12

Step-by-step explanation:

-5x + 4y = 3

x = 2y - 15

Manipulate the equations such that the coefficients of two variables are additive inverses

-5x + 4y = 3

x = 2y - 15

Inverse operations

-> 4y - 3 = 5x

-> 2y - 15 = x (*(-5))

->4y - 3 = 5x

-> -10y + 75 = -5x

Now add the equations to eliminate a variable,

4y - 3 = 5x

-10y + 75 = -5x

-6y + 72 = 0

Inverse operations

-6y + 72 = 0

72 = 6y

/6       /6

12 = y

Back solve to find (x)

2y - 15 = x

2(12) - 15 = x

24 - 15 = x

9 = x

Answer:

5 • 10^-4 I evaluate this by using scientific notation.

The value of the ratio  (3.5 x 10⁵) : (7x10⁸)  is 0.0005.

An expression is a sentence with at least two numbers or variables having mathematical operation. Maths operations can be addition, subtraction, multiplication, division.

For example, 2x+3

To solve (3.5 x 10⁵) : (7x10⁸), we can simplify the expression by dividing the numerical coefficients and dividing the exponents separately.

Dividing the numerical coefficients 3.5 and 7, we get:

3.5 ÷ 7 = 0.5

Dividing the exponents 5 and 8, we get:

10⁵ ÷ 10⁸ = 10⁵⁻⁸

              = 10⁻³

Therefore, the simplified expression is:

0.5 x 10⁻³

We can further simplify this expression by converting 10⁻³ to a decimal:

10⁻³ = 1/1000 = 0.001

So, the final answer is:

(3.5 x 10⁵) : (7x10⁸) = 0.5 x 10⁻³

                              = 0.5 x 0.001

                              = 0.0005

The given expressions and their equivalent expressions are:

Equivalent expressions are expressions that have the same value when evaluated or when you simplify each of them.

Let's evaluate and simplify each of the given expressions:

x − 4x + 6y + (14x − 5y)

Open bracket

x - 4x + 6y + 14x - 5y

Combine like terms

11x + y

Therefore, x − 4x + 6y + (14x − 5y) is equivalent to 11x + y

3x + 3y + 2(2x − y)

Open bracket

3x + 3y + 4x - 2y

Combine like terms

7x + y

Therefore, 3x + 3y + 2(2x − y) is equivalent to 7x + y.

(5x − 3y) − x + 3x − 5y

5x - 3y - x + 3x - 5y

7x - 8y

Therefore, (5x − 3y) − x + 3x − 5y is equivalent to 7x - 8y.

4(x + y) − 3(x + y)

4x + 4y - 3x - 3y

x + y

Therefore, 4(x + y) − 3(x + y) is equivalent to x + y.

5(x + y) + 6(x − y)

5x + 5y + 6x - 6y

11x - y

Therefore, 5(x + y) + 6(x − y) is equivalent to 11x - y.

Answer:

the scale factor is 5/4

Step-by-step explanation:

Given the data in the image below;

B is a dilation of square A, scale factor = ?

B is a dilation of square A, that is; B is a larger form of square A.

now, to get the scale factor;

The side length of Square B = 35

The side length of Square A = 28

so, the scale factor k will be;

K = 35 / 28

divided both the numerator and denominator by 7

K = 5/4

Therefore, the scale factor is 5/4

In math, a rate is a ratio that compares two different portions that have distinct units. for example, if we say John types 50 words in a minute, then his rate of typing is 50 words per minute. The word "per" gives a clue that we are dealing with a rate.

rate is a ratio among measurements using different units, for example, births per year, cost per person, words per minute.

All rate problems can be solved by using the formula D = R(T), which translates to distance (D) equals rate (R) multiplied by time (T)

Step-by-step explanation:

okay, so here are a few methods you can use.

___

1) +

x + 7 = 10 so because this is addition we use the reverse, subtraction. So

x - 7 = 10 - 7 and that equals to 3.

2) -

x - 2 = 10 so because this is subtraction we do the reverse, addition.

x + 2 = 10 + 2 and that equals to 12.

3) x

x times 3 = 21 because this is multiplying we divide.

x/3 = 21/3 and that would be 7.

4) /

x/2 = 10 same as above, reverse is multiplying.

x times 2 = 10 times 2 and thats 20.

Answer:

Número de boletos general = 8000

Número de boletos preferente = 2000

Step-by-step explanation:

Total de personas = 10000 personas

Venta total = $6600000

Ecuación para la venta total en terminos de boletos vendidos:

Número de boletos general = variable g

Número de boletos preferente = variable p

$500g + $1300p = $6600000

Simplifica la ecuación:

5g + 13p = 66000

Subsituye una de las variables usando la ecuación g + p = 10000:

g + p = 10000 => g = 10000 - p

5g + 13p = 66000 => 5(10000 - p) + 13p = 66000

Aislar la variable p:

5(10000 - p) + 13p = 66000

50000 - 5p + 13p = 66000

8p = 16000

p = 16000/8 = 2000

g = 10000 - p = 10000 - 2000 = 8000

Número de boletos general = 8000

Número de boletos preferente = 2000
