Question

Please pls please help and explain I have no idea

Answer 1

We are given the equation:

`V=hH(b_1+b_2)/(6)`

a) It's equired to solve the equation for b12.

Multipl both sides of ethe equation by 6 to eliminae denominators:

`6V=hH(b_1+b_2)`

Divide by hH to isolate the sum of b1 + b2:

`b_1+b_2=(6V)/(hH)`

Finally, subtract b1:

`b_2=(6V)/(hH)-b_1`

b) Given the values V = 216, h = 8, H = 9, and b1 = 5, substitute in the equation above:

`b_2=\frac{6\cdot216\text{ }cm^3}{8\text{ cm 9 cm}}-5\text{ cm}`

Calculating:

`\begin{gathered} b_2=\frac{1296\text{ }cm^3}{72\text{ cm}^2}-5\text{ cm} \\ \\ b_2=18\text{ cm}-5\text{ cm=13 cm} \end{gathered}`

Answer: b2 = 13 cm
