The fractions of all the supporters that are male and support the away

team is 1/3

The fractions of all the supporters that are female and support the away

team is 2/9.

A fraction is a value representing a part of a whole.

We have,

Supporters for the Home team = 4/9

Supporting for the away team = 1 - 4/9 = 5/9

Now,

Male supporters from the away team = 3/5 x 5/9 = 1/3

So,

Female supporters from the away team = (1 - 3/5) x  5/9 = 2/5 x 5/9 = 2/9

Thus,

The fractions of all the supporters that are male and support the away

team is 1/3

The fractions of all the supporters that are female and support the away

team is 2/9.

Answer:

  10 meters

Step-by-step explanation:

You recognize that the ratio of leg lengths of the right triangle involved is ...

  6 : 8 = 3 : 4

You know that any right triangle with leg lengths 3 and 4 has a hypotenuse of 5. The ladder will need to be in the same ratio:

  3 : 4 : 5 = 6 : 8 : 10

The ladder needs to be 10 meters long.

_____

In case you don't remember that (3, 4, 5) is a "Pythagorean triple," you can figure the length using the Pythagorean theorem.

  6^2 +8^2 = hypotenuse^2

  36 +64 = 100 = hypotenuse^2

  hypotenuse = √100 = 10 . . . . required ladder length in meters

Answer:

The volume of a cube with the side length 't' will be:

V = t³

Yes! the volume of the cube is a function of the side length as the volume is a dependent quantity and depends on the value of side length.

Step-by-step explanation:

We know that volume is the measurement of how much space a 3-d object takes up.

Given that the cube with the side length 't'.

As every edge of the cube is the same length.

Thus, the volume of a cube with the side length 't' will be:

V = t³

For example, if the side length t = 2 cm

Then,

V = 2³ = 8 cm³

Yes, the volume of the cube is a function of the side length as the volume is a dependent quantity and depends on the value of side length.

Answer:

40mph

Step-by-step explanation:

Using D = rt, the current variables we have are

D = 20 miles

t = 30 minutes

Since the goal is rate, we alter the equation to r = D/t.

In addition, we have to convert minutes into hours so we can

r = (20 / 30)*2/2

r = (40/60)

60 minutes is converted into an hour so the rate r is 40 miles per hour.

r = 40/1

Answer:

the rate of gas usage is 44.7 miles per gallon.

Answer: It is 10k - 4r + 5

Step-by-step explanation: For these type of questions, always combine like terms.

The dealer's cost of refrigerator is $456.

We are given the total selling price and mark up according to dealer's cost. So, let us assume the dealer's cost be x.

x + 5% × x = 478.80

Converting mark up percentage to fraction and then decimal form

x + 0.05x = 478.80

Performing addition on Left Hand Side of the equation to find the value of x

1.05x = 478.80

Shifting 1.05 to Right Hand Side of the equation

x = 478.80 ÷ 1.05

Performing division to Right Hand Side of the equation to find the value of x

x = 456

Hence, the dealer's cost will be $456.

Answer:

Step-by-step explanation:

The given equation is true for x=-5/3.

In mathematics, an equation is a formula that expresses the equality of two expressions, by connecting them with the equals sign =.

The given equation is 7x-2(x+1)+18 = 8x-11.

The solution of an equation is the set of all values that, when substituted for unknowns, make an equation true.

The solution for the equation 7x-2(x+1)+18 = 8x-11 is as follows

7x-2x-2+18 = 8x-11

⇒ 5x-16=8x-11

⇒ 8x-5x=-16+11

⇒ 3x=-5

⇒ x=-5/3

Verification:

Substitute x=-5/3 in the given equation and verify

That is, 5(-5/3)-16=8(-5/3)-11

⇒ -25/3 -16=-40/3 -11

⇒ (-25-48)/3 = (-40-33)/3

⇒ -73/3 =-73/3

LHS = RHS

Therefore, the given equation is true for x=-5/3.

Step-by-step explanation:

Like terms are are terms whose variables (and their exponents such as the 2 in x 2) are the same. In other words, terms that are "like" each other. Note: the coefficients (the numbers you multiply by, such as "5" in 5x) can be different.

So like in your picture x and x would be like terms... your picture helps as well to identify your like terms because your like terms have the same background color to there particular rectangle.

Se necesitan conductores voluntarios para llevar a 80 estudiantes al juego de béisbol del campeonato. Los conductores cuentan con automóviles, con capacidad para 4 estudiantes, o camionetas, con capacidad para 6 estudiantes. La ecuación describe la relación entre la cantidad de automóviles y la cantidad de camiones que pueden transportar exactamente 80 estudiantes.

Seleccione todas las afirmaciones que sean verdaderas sobre la situación.

a) Si van 12 coches, se necesitan 2 furgonetas.

b) c = 14 y v = 4 son un par de soluciones de la ecuación.

c) Si van 6 coches y van 11 furgonetas, habrá espacio adicional.

d) 10 coches y 8 furgonetas no son suficientes para transportar a todos los estudiantes.

e) Si pasan 20 autos, no se necesitan camionetas.

f) 8 furgonetas y 8 coches son números que cumplen con las limitaciones en esta situación.

Answer:

La opción b, e y f.

Step-by-step explanation:

Pasando por las opciones dadas:

c = coches que pueden llevar a 4 estudiantes

v = furgonetas con capacidad para 6 estudiantes

a) Si van 12 coches, se necesitan 2 furgonetas.

= 12 (4) + 2 (6)

= 48 + 12

= 60

60 ≠ 80

La opción a es incorrecta

b) c = 14 y v = 4 son un par de soluciones de la ecuación.

14 (4) + 4 (6)

56 + 24 = 80 estudiantes

La opción b es correcta

c) Si van 6 coches y van 11 furgonetas, habrá espacio adicional.

Por lo tanto:

5 (4) + 11 (6)

= 20 + 66

= 86.

86 es mayor que 80, la opción c es correcta, habría un espacio adicional para 6 estudiantes.

d) 10 coches y 8 furgonetas no son suficientes para transportar a todos los estudiantes.

Por lo tanto:

10 (4) + 8 (6)

40 + 48

= 88

e) Si pasan 20 autos, no se necesitan camionetas.

20 (4) = 80 estudiantes

La opción e es correcta

f) 8 furgonetas y 8 coches son números que cumplen con las limitaciones en esta situación.

8 (6) + 8 (4)

= 48 + 32

= 80 estudiantes.

La opción b es correcta

Por lo tanto, la ecuacióna que describe la relación entre la cantidad de automóviles y la cantidad de camiones que pueden transportar exactamente 80 estudiantes es la opción b, e y f.

Step-by-step explanation:

Get the absolute value by itself. Do that by multiplying by 4.

  |3x +15| > 12

This resolves to two cases:

3x +15 > 12

  x +5 > 4 . . . . divide by 3

  x > -1 . . . . . . .subtract 5

-(3x +15) > 12

  x +5 < -4 . . . . divide by -3

  x < -9 . . . . . . . subtract 5
