Hey there! I'm happy to help!

We want to get m all by itself on one side of the equation. To do this, we use inverse operations on both sides of the equation to cancel out variables on one side to isolate m.

am/c=n

We multiply both sides by c.

am=nc

We divide both sides by a.

m=(nc)/a

I hope that this helps! Have a wonderful day! :D

Step-by-step explanation:

The Population pyramids or the age pyramid visualizes the demographic structure of any population. It is the graphical illustration which shows the distribution of the various age groups in the population.

The width of the pyramid represents the size of a population for a given age. Men are shown to the left and the women on the right.

The population pyramid between the age group will look like a pyramid with a very large width at the bottom and narrowing top.

Step-by-step explanation:

Initially, let the side of the cubical box is [tex]a[/tex] inches,

So, the volume of the box, [tex]x = a \times a \times a= a ^3[/tex].

Given that [tex]g(x)=\sqrt[3]{x} =\sqrt[3]{a^3}[/tex]

[tex]\Rightarrow g(x)=a \; \cdots (i)[/tex]

On doubling the volume of the box, the new volume is [tex]2x[/tex].

So, [tex]g(x)=\sqrt[3]{2x} =\sqrt[3]{2a^3}[/tex]

[tex]\Rightarrow g(x)=\sqrt[3]{2} a \; \cdots (i)[/tex]

As [tex]\sqrt[3]{2} >1[/tex], so the graph of  [tex]g(x)=\sqrt[3]{2} a[/tex] will be above of the [tex]g(x)=a[/tex] as shown in the graph.

Answer: True

If one variable goes down, then the other goes up, and vice versa. Think of it like a see-saw. We'll have x on one side pushing down to make y go up. An example of this would be y = 1/x which graphs out a hyperbola.

The statement "two variables is inverse when a decrease in one variable is associated with an increase in the other variable." is True statement.

One kind of proportionality relationship is inverse proportion. If two quantities are inversely related, one will increase while the other will decrease. Building a wall would be an example of an inverse proportion in action.

Given:

We know in direct relation if one quantity increase then another quantity increase.

and, in Inverse Relation if one quantity increase then other Quantity decrease.

So, two variables is inverse when a decrease in one variable is associated with an increase in the other variable is true statement.

The answer should be 1/12 because a a cube has 6 sides rolling it twice would make it 12.

Answer:

see explanation

Step-by-step explanation:

Given

2x + 3y = 4 ( subtract 2x from both sides )

3y = - 2x + 4 ( divide all terms by 3 )

y = - [tex]\frac{2}{3}[/tex] x + [tex]\frac{4}{3}[/tex]

To determine if the point (2, 1) lies on the line, substitute x = 2 into the right side of the equation and if the value obtained equals the y- coordinate of the point then it lies on the line.

y = - [tex]\frac{4}{3}[/tex] + [tex]\frac{4}{3}[/tex] = 0 ≠ 1

Ths (2, 1) does not lie on the line

Step-by-step explanation:

Hey, there!!

The given is a point (-6,8) through which a line passes. And is perpendicular to the line y = 2x-4

The equation for point (-6,8) is,

(y-8)= m1(x+6)...........(i)

and given equation is y = 2x-4............(ii)

Now, from equation (ii).

slope (m2)= 2 { as equation (ii) is in the form of y= mx+c where m is a slope}.

Now, For perpendicular,

m1×m2= -1

m1×2= -1

[tex]m1 = \frac{ - 1}{2} [/tex]

Therefore, m1 = -1/2.

Putting, the value of m1 in equation (i).

(y-8) = -1/2×(x+6)

2(y-8)= -1(x+6)

2y - 16 = -x -6

x+2y-10 = 0......... is the required equation.

Answer:

[tex]AM =40[/tex]

Step-by-step explanation:

Given

[tex]AM = 5x + 10[/tex]

[tex]MB = 4x + 16[/tex]

Required

Determine AM

Since M is the midpoint, we have that;

[tex]AM = MB[/tex]

Substitute values for AM and MB

[tex]5x + 10 = 4x + 16[/tex]

Collect Like Terms

[tex]5x - 4x = 16 - 10[/tex]

[tex]x = 6[/tex]

To solve for AM; substitute 6 for x in [tex]AM = 5x + 10[/tex]

[tex]AM = 5 * 6 + 10[/tex]

[tex]AM =30 + 10[/tex]

[tex]AM =40[/tex]

Answer:

y=2 16/25

in other words, two and sixteen twenty-fifths

Step-by-step explanation:

y/2-1/5=2-y/3

Move the variables to one side and constants to the other

y/2+y/3=2+1/5

Multiply y/2 by 3/3 and y/3 by 2/2 so that they have a common denominator

3y/6+2y/6=2 1/5

5y/6=11/5

Cross multiply

66=25y

y=66/25

y=2 16/25

Step-by-step explanation:

(A)

Length of wire = 30.48 m

Area of cross section = 3.22 * 10 ^ -5 m^2

[tex]R = k \frac{l}{a} [/tex]

[tex]k = \frac{R \times a}{l} = \frac{0.08 \times 3.22 \times {10}^{ - 5} }{30.48} = 8.45 \times {10}^{ - 8} ohm \: m^{ - 1} [/tex]

(B) length of wire = 1219.2 m

Area of cross section = 1.29 * 10^-5 m^2

Resistance = 8.45 * 10^-8 * 1219.2 / 1.29 * 10^-5 = 7.98 Ohms

Answer:

2a² = c²

Step-by-step explanation:

Right triangles follow the Pythagorean Theorem, a² + b² = c². The hypotenuse (c) must be the longest of the sides. In the given triangle, both legs measure a units. So, a = b. Therefore, we have a² + a² = c² or 2a² = c².

The equation can be used to determine if the triangle is a right triangle is c² = 2a².

The relationship between the three sides of a right-angled triangle is explained by the Pythagoras theorem, commonly known as the Pythagorean theorem. The Pythagorean theorem states that the square of a triangle's hypotenuse is equal to the sum of its other two sides' squares.

The well-known Pythagorean Theorem states that the square on the hypotenuse of a right triangle equals the sum of the squares on its legs.

The longest side measures c units.

The other sides of the triangle measure a units.

As, we know that longest side is the Hypotenuse.

Using the Pythagorean Theorem

H² = P² + B²

c² = a² + a²

c² = 2a²

So, the Correct statement is c² = 2a².

#SPJ6

Answer:

He is watching TV for 2 hours and 40 minutes.

Step-by-step explanation:

We are given that the episodes of a TV program are each 40 minutes long. Phill watches four episodes together.

As it is stated that the length of each episode of a TV program is 40 minutes, so the length of four episodes is given by;

1 episode = 40 minutes

4 episodes = 4 [tex]\times[/tex] 40

                  = 160 minutes

So, the length of four episodes together is 160 minutes.

Now, we have to convert the time in hours and minutes;

As we know that 1 hour = 60 minutes

160 minutes = 120 minutes + 40 minutes

                    = 2 hours + 40 minutes

Hence, the length of four episodes together is 2 hours and 40 minutes.
