The useful life of a certain piece of equipment is determined by the following formula: u=(8d)/h^2, where u is the useful life o
Anni [7]

Answer:

The correct answer is E.

Step-by-step explanation:

First I look for the relationships between the coefficients. The first term corresponds to the base value.

\frac{8*d}{h^{2}}  = \frac{8}{1} * \frac{d}{h^{2} }

The second term corresponds to the value obtained when the density of the underlying material is doubled and the daily usage of the equipment is halved.

\frac{2*8*d}{(0,5*h)^{2}}  = \frac{16*d}{0,25 * h^{2}}  = \frac{16}{0,25} * \frac{d}{h^{2} }

With the I get the ratio of coefficients of \frac{d}{h^{2}} :

\frac{8}{1} = 8

\frac{16}{0,25} = 64

Now I calculate  the percentage increase in the useful life of the equipment as:

% = \frac{64}{8} * %100 = %800
