9x + 4) + (6x - 6)
15x - 2 = 0
15x - 2 + 2 = 2
15x = 2
X = 2/15 = 0.133333333

Water level in a well was 20m below ground level. During rainy season, rainwater collected in different water tanks was drained
IgorC [24]

Answer:

17 m

Step-by-step explanation:

As shown in the figure,  A_0-B_0 is the ground level, A_1-B_1 is the old level of water which was at 20 m below ground level, A_2-B_2 is the new level of water which is 5m above of old level. The height of wall of the well, 1.20 m, and the the pelly at 80 cm =0.80 m, has been shown too.

The minimum length of the rope is equal to the distance between the pully and the new water level, indicated by the length L_0 in the figure.

So, L_0= 20-5+1.20+0.80= 17m

Hence, Raghu must use a rope having the minimum length 17 m to draw water from the well.

A tube is being stretched while maintaining its cylindrical shape. The height is increasing at the rate of 2 millimeters per sec
hoa [83]

Answer:

V = πr²h

S=2πrh

h= 2/3 millimeters

new height= 8/3 millimeters

S= 8π  millimeters square

New surface area = 32π  millimeters square

Step-by-step explanation:

The volume of the cylinder is given by V = πr²h   where r is the radius and h is the height.

The surface area of the cylinder is given by  S= 2πrh + 2πr²

Where πr² gives the area of the base and 2πr² gives the area of the top and bottom surfaces. The surface area S of a cylinder, not including the top and bottom of the cylinder, is therefore S=2πrh.

V = πr²h

96π= π (6*6) (h+2)

96 = 36 (h+2)

96/36= h+2

h= 96/36-2

h= 96-72/36

h= 24/36

h= 4/6

h= 2/3 millimeters

New height

h + 2= 2/3 + 2

= 2+6/3= 8/3 millimeters

Now S =2πrh

S = 2π(6) (2/3)

S= 8π  millimeters square

New Surface area

S = 2π(6) (8/3)

S= 32π  millimeters square
