(a) A cylindrical water tank of diameter 1.4m and height 2.1 m is being fed by a cive ot du3.5 cm through which water flows at the rate of 2m/ s. calculate the tirne it zabetank (4)

Answer»

Answer:

The time taken by the pipe to fill the cylinder is 28 minutes and 20 seconds.

Step-by-step explanation:

Given the diameter of cylinder = 1.4 m

=> Radius = 1.4/2 = 0.7 m

We know that volume of a cylinder = πr²h

= 3.14 x 0.7² x 2.1= 3.23 m³

For the pipe radius = 3.5/2 = 1.75 cm = 0.0175m

water flows at a rate of 2 m per second

So, volume of water discharged in one second by pipe = πr²L

= 3.14 x 0.0175² x 2=0.0019

Hence time taken by the pipe to fill the cylinder

= 3.23/0.0019= 1700 sec

= 28 minutes and 20 seconds

Hence the time taken by the pipe to fill the cylinder is 28 minutes and 20 seconds.

In the figure below, line q in the standard (x,y)coordinate plane has equation -2x + y- 1 andintersects line r, which is distinct from line q, at apoint on the x-axis. The angles, La and Lb, formed bythese lines and the x-axis are congruent. What is theslope of line r?2LaG. _1H. 1J. 2K. Cannot be determined from the given information22 -1

Answer»

First, turn our given equation for line q into proper slope-intercept form.

−2x+y=1

y=2x+1

Now, we are told that the angles the lines form are congruent. This means that the slopes of the lines will be opposites of one another [Note: perpendicular lines have opposite reciprocal slopes, so do NOT get these concepts confused!].

Since we have already established that the slope of line q is 2, line r must have a slope of -2.

Our final answer is F, -2

4. Two almirahs are purchased for 7800. 200 was spent on the transportation. One of them is sold at aprofit of 40% and the other one at a loss of 40%. If the selling price was same in both the cases, find thecost price of each almirah?

Answer»

Let the selling price of each almirah be x then let the two Almirah be A and B.

A is sold at a profit and B is sold at a loss.

A:

Selling price = x

Buying price = 0.6x

B:

Selling price = x

Buying price = 1.40x

The buying price of the two is 7800 meaning :

0.6x + 1.4x = 7800

2x = 7800

x = 3900

Buying price of A is :

0.6 × 3900 = 2340

B :

1.4 × 3900 = 5460

Since this is inclusive of transportation cost, we subtract 100 from each to get.

A = 2340 - 100 = 2240

B = 5460 - 100 = 5360

1 Arvind bought a dining table for? 23,850. This includes 6% sales tax. The shopkeeper has mof 125 % on his investment. If the shopkeeper has spentactual cost of the table?ing and transportation, what is theld the land1000 on polish

Answer»

Let the actual cost of the table be Rs C.cost incurred by the shopkeeper = Rs 1000.Total cost for shopkeeper = C + 1000Profit = 25%Sale price without tax = (C + 1000) * (100+25)/100 = 5 * (C + 1000)/4Sales tax = 5*(C + 1000)/4 * 6/100

total price paid by Arvind = 5 (C + 1000) /4 * 106/100 = Rs 23, 850 C + 1000 = 18000 C = Rs 17, 000that is the actual cost

Short Answer Type QuestionsFour metal cubesur metal cubes with edges 9 cm, 6 cm, 4 cm and 2 cm are melted together and a singl4 bwcube is formed with a wastage 17 cm3. Find the total surface area of the new cube.

Answer»

Volume of all the cubes = 9×9×9 + 6×6×6 + 4×4×4 + 2×2×2= 729 + 216 + 64 + 8= 1017 cm^3

wastage = 17cm^31017 - 17 cm^3=1000 cmm^3

edge of the new cube formed = cube root of 1000=10 cm

therefore surface area of cube = 6a^26 × 10^26 × 100600 cm^2

Therefore the answer is 600cm^2
