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

Simora [160]

M + s = 10 or s = 10 - m
3m + 2s = 23 
substitute first equation into second equation: 
3m + 2(10 - m) = 23 
3m + 20 - 2m = 23 
m = 3 
using first equation: 
s = 10 - 3 = 7 
check using second equation: 
3(3) + 2(7) = 23 
9 + 14 = 23 checks 
He hit 7 stationary and 3 moving targets.
