If the volume of a rectangular pyramid is 150 inches cubes ,what is the volume of a prism with the same demensions
Ugo [173]

\bf \stackrel{\textit{volume of a pyramid}}{V=\cfrac{Bh}{3}}\qquad \qquad \stackrel{\textit{volume of a rectangular prism}}{V=Bh}\qquad \begin{cases} B=base~area\\ h=height \end{cases}


so let's notice, the volume of the rectangular prism is really 3 times as much of that of a pyramid with the same Base and Height.

so if the pyramid has a volume of 150, the prism will have volume of 3*150.

1 - Qual a solução da equação 3x – 4 = 14? * 1 ponto a) 10 b) 7 c) 6 d) 15 2 - A idade de um pai é igual ao triplo da idade do f
topjm [15]

Responda:

1.) 6;

2.) d) O pai tem 36 anos e o filho tem 12 anos.

Explicação passo a passo:

1.)

Dada a equação: 3x - 4 = 14

3x = 14 + 4

3x = 18

Divida os dois lados por 3

x = 6

2) Dado que ;

Idade do pai = 3 vezes a idade do filho

Idade do pai + idade do filho = 48

Deixe a idade do pai = f; idade da criança = c

Matematicamente ;

f = 3c - - - (1)

f + c = 48 - - - - (2)

Substitua f = 3c em (2)

3c + c = 48

4c = 48

c = 48/4

c = 12

Substitua c = 12 em (2)

f + 12 = 48

f = 48 - 12

f = 36

Portanto ;

Idade do pai = 36 Idade da criança = 12
