A semi trailer is being packed with boxes that are 1 1/2 feet on each edge. The cargo space of the trailer is 28 feet long, 8 1/

CaHeK987 [17]

Answer: Last option is correct.

Step-by-step explanation:

Since we have given that

Length of the cargo space of the trailer = 28 ft

Width of the cargo space of the trailer is given by

$8\frac{1}{2}\\\\=\frac{17}{2}\ ft$

Height of the cargo space of the trailer is given by

$9\frac{1}{6}\\\\=\frac{55}{6}\ ft$

Volume of the cargo space of the trailer is given by

$Volume=length\times width\times height\\\\Volume=28\times \frac{17}{2}\times \frac{55}{6}\\\\Volume=2181.67\ cm^3$

Now. Length of each edge of a semi-trailer is given by

$1\frac{1}{2}\\\\=\frac{3}{2}\ ft$

So, Volume of semi-trailer is given by

$Volume=a^3\\\\Volume=\frac{3}{2}\times \frac{3}{2}\times \frac{3}{2}\\\\Volume=\frac{27}{8}\\\\Volume=3.375\ ft^3$

So, Maximum number of boxes that will fit inside the trailer is given by

$\frac{\text{Volume of cargo space}}{\text{ volume of semi trailer}}\\\\=\frac{2181.67}{3.375}\\\\=646.42$

Hence, According to options, it is nearest to 633.

Therefore, Last option is correct.

You received a score of 3.4 on your annual review. Merit increases are given out starting at .5% at a score of 2.6 and it goes u

Anna35 [415]

The merit increase will be 2.5%

Step-by-step explanation:

The score received for annual review is 3.4 and the merit increases are starting at 0.5% at a score of 2.6 and goes up 1% every 0.4 points.

Now, subtracting

$3.4-2.6=0.8$

And this is exactly 2 times of 0.4 points.

Hence, the merit increase will be 0.5%+1%+1%=2.5%

A scientist measured the energy of a system and found that it was increasing. The data shown represent the energy taken every bi

DiKsa [7]

At start ( t = 0 nanoseconds ) :

E ( t = 0 ) = 2.645 J

E ( t = 1 ) = 6.290 J

E ( t = 1 ) : E ( t = 0 ) = 6.290 : 2.645 = 2.37

Also:

E ( t = 2 ) : E ( t = 1 ) = 14.909 : 6.290 = 2.37

E ( t = 3 ) ; E ( t = 2 ) = 35.335 : 14.909 = 2.37

Therefore, the formula for calculating the energy of the system is:

E ( t ) = 2.645 * 2.37 ^ t

The answer is 4) exponential growth.
