Simplify by combining like terms 4s + 1/6s + 2 3/5s

HACTEHA [7]

<h3>The solution by combining like terms is 6.7667</h3>

Solution:

Given expression is:

$4s + \frac{1}{6}s + 2\frac{3}{5}s$

We have to simplify by combining the like terms

From given,

$4s + \frac{1}{6}s + 2\frac{3}{5}s$

Convert the mixed fraction to improper fraction

$4s + \frac{1}{6}s + \frac{13}{5}s$

Make the denominator same

$\frac{4s \times 30 }{30} + \frac{1s \times 5}{6 \times 5} + \frac{13s \times 6}{5 \times 6}\\\\\frac{120s}{30} + \frac{5s}{30} + \frac{78s}{30}\\\\\frac{203}{30} = 6.7667$

Thus the solution is 6.7667

Solve the problem.

Aleksandr [31]

Answer:

The given equation is

$\theta = cot^{-1}(\frac{r}{h} )$

Which is the definition of the angle of repose.

Remember that the angle of repose refers to the angle between the horizontal plane and the inclined side of the cone formed when we allow to fall freely granular materials.

We know by given

$h=19\\r=\frac{d}{2}=\frac{30}{2}=15$

Replacing these values, we have

$\theta = cot^{-1}(\frac{15}{19} ) \approx 38.29 \°$

Therefore, the angle of repose is 38.29° approximately.

Now, if the base diameter is 104 feet, the height would be

$38.29 = cot^{-1}(\frac{52}{h}\\tan(38.29)=\frac{52}{h}\\ h=\frac{52}{0.79} \approx 65.8$

Therefore, the height would be 65.8 feet, assuming that the angle of repose is the same.
