Answer:

Volume of pyramid=\frac{hs^2}{3}

Step-by-step explanation:

Volume of pyramid =\frac{1}{3}\times \texttt{base area}\times \texttt{height}

Here base is of square shape with side of s.

Area of base =  s x s = s²

Height of pyramid = h

Volume of pyramid=\frac{1}{3}\times s^2  \times h=\frac{hs^2}{3}

El perímetro de un rectángulo es de 72 cm. Halla el área del rectángulo si su largo es el 25% más grande que su ancho
maxonik [38]

Answer:

Las dimensiones del rectángulo son:

ancho = 16 cm

largo = 20 cm

Step-by-step explanation:

Consideración:

La formula del perímetro de un rectángulo es:

perímetro = 2(largo + ancho)

25% más grande = 125% = 125/100 = 1.25

Planteamiento:

2(a+b) = 72

b = 1.25a

a = longitud del ancho

b = longitud del largo

Desarrollo:

de la primer ecuación del planteamiento:

a+b = 72/2

a+b = 36

b = 36 - a        Ec. 3

Igualando la segunda ecuación del planteamiento con la Ec. 3:

1.25a = 36 - a

1.25a + a = 36

2.25 a = 36

a = 36/2.25

a = 16

de la Ec. 3:

b = 36 - a

b = 36 - 16

b = 20

Comprobación:

de la primera ecuación del planteamiento:

2(a+b) = 72

2(16+20) = 72

2*36 = 72

A plane traveled 1463 miles to Moscow and back. The trip there was with the wind. It took 11 hours. The trip back was into the w
Studentka2010 [4]

The speed of plane is 105 miles per hour and speed of wind is 28 miles per hour.

Step-by-step explanation:

Given,

The distance traveled by plane = 1463 miles

The trip with the wind took 11 hours.

The trip took 19 hours against the wind.

Let,

s be the speed of plane and w be the speed of wind.

Therefore;

Speed with the wind = s+w

Speed into the wind = s-w

We know that;

Distance = Speed * Time

Therefore;

Equation for trip taken with wind.

1463 = 11(s+w)

Dividing both sides by 11

\frac{1463}{11}=\frac{11(s+w)}{11}\\133=s+w\\s+w=133\ \ \ Eqn\ 1

Equation for trip taken into the wind

1463 = 19(s-w)

Dividing both sides by 19

\frac{1463}{19}=\frac{19(s-w)}{19}\\77=s-w\\s-w=77 \ \ \ Eqn\ 2

Adding Eqn 1 and 2

(s+w)+(s-w)=133+77\\s+w+s-w=210\\2s=210

Dividing both sides by 2

\frac{2s}{2}=\frac{210}{2}\\s=105

Putting s=105 in Eqn 1

105+w=133\\w=133-105\\w=28

The speed of plane is 105 miles per hour and speed of wind is 28 miles per hour.
