Answer:

Option 4) The area of the flower bed is smaller than 4 square feet.

Step-by-step explanation:

Let’s solve for the area of the flower bed.

Consider that the flower bed is a rectangle.

The area of a recrangle is given by the formula:

A = length x width

The area of the flower bed is:

4 ft x 4/6 ft = 2 2/3 ft^2

2 2/3 ft ^2 < 4 ft^2

Therefore option 4 is the correct answer.

group of 30 students from your school is part of the audience for a TV game show the total number of people in the audience is 1

Soloha48 [4]

<h2>Answer:</h2><h2>The theoretical probability of four students from your school being selected as contestants out of 8 possible contestants spots = $\frac{14}{165}$ </h2>

Step-by-step explanation:

The number of students participated = 30

Total audience = 150

By probability , to find the solution = $\frac{n(E)}{n(S)}$

where n(E) is the number of favorable outcomes,

n(S) is the number of total outcomes.

n(S) is the number of ways any 8 students can by picked from the audience= $\frac{8}{140}$

n(E) is the probability of picking four students from our school and five students from another school.

n(E) = $(\frac{4}{30}) (\frac{4}{110})$ = $\frac{16}{3300}$

$\frac{n(E)}{n(S)}$ = $\frac{\frac{16}{3300}}{\frac{8}{140}}$ = $\frac{14}{165}$

Resuelve las siguientes ecuaciones y luego verifica<br> A-)3x +1=7<br> B-)2a-2=1+3a

jarptica [38.1K]

Answer:

A) x=2

B) a=-3

Step-by-step explanation:

La primera ecuación dada es,

A) 3x + 1 = 7

Reste 1 de ambos lados, tenemos

3x +1-1=7-1

$\Rightarrow 3x=6$

Dividir por 3 (ya que 3 es un número distinto de cero) de ambos lados, tenemos

$\frac{3x}{3}=\frac {6}{3}$

$\Rightarrow x=2$

Ahora, compruebe si x = 2 es la solución correcta o no.

El lado izquierdo de la ecuación dada es 3x + 1.

Ponga x = 2, tenemos

$3\times2+1=7$

Que es igual al lado derecho de la ecuación dada.

Por tanto, x = 2 es la solución correcta.

La segunda ecuación es

B) 2a-2=1+3a

Reste 3a de ambos lados, tenemos

2a-2-3a=1+3a-3a

$\Rightarrow -a-2=1$

Suma 2 de ambos lados, tenemos

-a-2+2=1+2

$\Rightarrow -a=3$

Multiplica por -1 (como -1 es un número distinto de cero) de ambos lados, tenemos

$-a\times (-1)=3\times(-1)$

$\Rightarrow a=-3$

Ahora, verifique si a = -3 es la solución correcta o no

El lado izquierdo de la ecuación dada es 2a-2.

Ponga a = -3, tenemos

$2\times(-3)-2=-8$

El lado derecho de la ecuación dada es 1 + 3a.

Ponga a = -3, tenemos

$1+3\times(-3)=-8$ .

Aquí, al poner a = -3, el valor del lado izquierdo es igual al valor del lado derecho.

Por tanto, a = -3 es la solución correcta.

An average tub bath uses 8 gallons of water and an average shower uses 6 gallons. to provide baths for 60 people, how much more

viva [34]

<span>You need (8-6) 2 extra gallons to take a bath. With sixty people bathing, you'll need 60*2=120 extra gallons to meet the extra demand for water. Alternatively, you could note that 60 bathers*8 gallons per bath=480 gallons of water would be used for 60 baths and 60*6=360 needed for showers. The difference would be 480-360=120 gallons.</span>
