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

A rectangle room is 12 1/2 feet long and 10 1/3 feet wide. what is the area of the room

Veronika [31]

Answer:

129 1/6 feet

Step-by-step explanation:

Formula for area is L*W

1. convert the mixed numbers to improper fractions

12 1/2 feet = 25/2

10 1/3 feet = 31/3

2. multiply numerator by numerator (25*31 = 775

3. multiply denominator by denominator (2*3=6

4. convert improper fraction 775/6 into a mixed number by dividing 775 by 6.

5. 775/6 = 129 r. 1 or 129 and 1/6
