ipn [44]

Answer:

volume of fodder=1/3pie R^2h= $\frac{1}{3} *\frac{22}{7} * (3.6)^2 *2.1=28.51m^3$

l^2=r^2+h^2

l^2=(2.1)^2+(3.6)^2

l^2=4.441+12.96=17.37

l= $\sqrt{17.37}$ =4.17m

minimum area of polythene to cover fodder=pieRl= $\frac{22}{7} *3.6*4.17=47.18m^2$

the volume of fodder is $28.51m^3$ and minimum area of polythene to cover fodder in the rainy seasonv47.18m^3

DENIUS [597]

Answer:

The difference in finishing time between the 2nd and 3rd places is the shortest and it is 0.07 seconds.

Step-by-step explanation:

The first positioned swimmer took 55.98 seconds and the second positioned swimmer took 56.87 seconds to complete the race.

So, the difference is (56.87 - 55.98) = 0.89 seconds.

The second positioned swimmer took 56.87 seconds and the third positioned swimmer took 56.94 seconds to complete the race.

So, the difference is (56.94 - 56.87) = 0.07 seconds.

The third positioned swimmer took 56.94 seconds and the fourth positioned swimmer took 57.17 seconds to complete the race.

So, the difference is (57.17 - 56.94) = 0.23 seconds.

The fourth positioned swimmer took 57.17 seconds and the fifth positioned swimmer took 57.27 seconds to complete the race.

So, the difference is (57.27 - 57.17) = 0.10 seconds.

The fifth positioned swimmer took 57.27 seconds and the sixth positioned swimmer took 57.35 seconds to complete the race.

So, the difference is (57.27 - 57.35) = 0.08 seconds.

Therefore, the difference in finishing time between the 2nd and 3rd places is the shortest and it is 0.07 seconds. (Answer)

Pleasee Help!!! v2=?

adoni [48]

<h3>Given :</h3>

$\sf l = p(v_{2} - v_{1})$

<h3>To Find :</h3>

$\tt v_{2} = ?$

<h3>Solution :</h3>

$\sf \dashrightarrow l = p(v_{2} - v_{1})$

$\sf \dashrightarrow \dfrac{l}{p} = v_{2} - v_{1}$

$\sf \dashrightarrow \dfrac{l}{p} + v_{1} = v_{2}$

$\sf \dashrightarrow v_{2} = \dfrac{l}{p} + v_{1}$

$\large \underline{\boxed{\bf{v_{2} = \dfrac{l}{p} + v_{1}}}}$

Hence, value of $\sf v_{2} = \dfrac{l}{p} + v_{1}$

Answer:

The second base of the trapezoid b2 is 2.5 inches

Step-by-step explanation:

Here, we want to calculate the second base of the trapezoid.

Mathematically, the area of a trapezoid can be given as;

A = 1/2(a + b) h

where a and b represents the parallel bases and h is the height of the trapezoid

so this, we have from the question

1/2(4.5 + b2) * 6 = 21

3(4.5 + b2) = 21

divide both sides by 3

4.5 + b2 = 7

b2 = 7-4.5

b2 = 2.5 inches
