Particle travels along a circular path that has a radius of 3 feet. The angular velocity of the particle is 18 radians per minut

Gala2k [10]

We know that

[length of a circumference ]=2*pi*r
for r=3 ft

[length of a circumference ]=2*pi*3-----------> 18.84 ft

<span>The angular velocity of the particle is 18 radians per minute.

if 2pi radians (full circle)------------------> 18.84 ft
18 radians----------------------------------> X
X=18*18.84/(2*pi)---------> X=54 ft
so
</span>The linear velocity of the particle is 54 ft/minute

the answer is
54 ft/min

After allowing 20% discount on the marked price with 13%

saveliy_v [14]

<u>Answer:</u>

The marked price of the article is 22,600

<u>Explanation: </u>

Given, selling price of an article SP = Rs. 18080

To calculate marked price MP, the formula used is

$\mathrm{SP}=\mathrm{MP}\left(1-\frac{D \%}{100}\right)$

Discount D = 20%

Substituting the given values

SP = $\mathrm{MP}\left(1-\frac{20}{100}\right)$

18080 = $\mathrm{MP}\left(1-\frac{1}{5}\right)$

$18080=\mathrm{MP}\left(\frac{4}{5}\right)$

$\mathrm{MP}=\frac{18080 \times 5}{4}$

MP = Rs. 22,600

Therefore the marked price of the article is 22,600

What is the volume of grain that could completely fill this silo, rounded to the nearest whole number? Use 22 over 7 for pi. (4

saveliy_v [14]

Answer: $19,461\ ft^3$

Step-by-step explanation:

The missing figure is attached.

The volume of grain that could completely fill this silo is the sum of the volume of the cylinder and the volume of the hemisphere.

By definition, the volume of a cylinder can be calculated with this formula:

$V_c=\pi r^2h$

Where "r" is the radius and "h" is the height.

In this case you know that:

$r=6\ ft\\\\h=168\ ft$

And the volume of a hemisphere can be found using the following formula:

$V_h=\frac{2}{3} \pi r^3$

Where "r" is the radius.

In this case:

$r=6\ ft$

Therefore, the volume of grain that could completely fill this silo, rounded to the nearest whole number, is:

$V_{grain}=(\frac{22}{7})(6\ ft)^2 (168\ ft)+\frac{2}{3} (\frac{22}{7})(6\ ft)^3\\\\V_{grain}\approx19,461\ ft^3$

Geometry: Line QS bisects angle PQR. Solve for x and find the measure of angle PQR.

Kazeer [188]

It is given in the question that,

Line QS bisects angle PQR. Solve for x and find the measure of angle PQR.

And

$m \angle PQS = 2x+1
\\
m \angle RQS = 4x-15$

Since QS bisects angle PQR, therefore

$m \angle PQS = m \angle RQS$

Substituting the values, we will get

$2x+1=4x-15
\\
1+15 = 4x-2x
\\
2x = 16
\\
x = 8$
