A rectangular tank is 25 m long, 1 200 cm wide and 6 000 mm deep. The tank is open at the top. Thecost of plastering the inside of its walls and bottom (floor) at R26 per square metre is[1] R19 344,00.[2] R46 800,00.[3] R7 800,00.[4] R13 572,00.

Answer»

Answer:

WIDTH = 1200×10 = 12000mm

length = 25×1000 = 25000mm

height = 6000mm

area of inner WALLS and FLOOR = 2(lb+bh+lh)-lb

= 2(bh+lh)+lb

= 2(12000×6000+25000×6000)+25000×12000

= 2(72000000+150000000)+300000000

= 2(222000000)+300000000

= 444000000+300000000

= 744000000mm

= 74400000cm

= 744000m

cost = 26×744000

= ₹19244000

Solution set of x(x^2+x+1)≤0 is​

Answer»

Answer:

Step-by-step explanation:

Answered Mar 1, 2015

The question is  

x(x-1)(x+2)>0

Firt ignore the '>' sign:

so:   x(x-1)(x+2)=0

Since 3 numbers are multiplied to give 0, then each may potentially be zero, so:  

  x = 0

  x - 1 = 0,  which means x = 1

  x + 2 = 0, which means x = -2

So, you have 3 numbers  -2, 0, 1  

Now, draw a straight line and mark these 3 points on the line. You can see now that it these numbers have divided the line into 4 different regions. Region 1 is (-inf, -2) -- that is all numbers to the left of -2.

Region 2 is (-2,0) ---  that is all numbers between -2 and 0

Region 3 is (0,1) --- that is all numbers between 0,1

Region 4 is (1,inf)--- that is all numbers to the right of 1

 

Your strategy now, is to test a number inside of each of these 4 regions. Basically you pick a number inside, but not the end values. You substitute the number into the ORIGINAL inequality for x, and see which ones are true.

Hence:

Region 1: (-inf, -2),  

I can choose -5 since its in the region to the left of -2.

I get:        

(-5)(-5-1)(-5+2) >? 0       I used '?' because I am not sure if it is true

so:  (-5)(-6)(-3) >? 0  

Finally   -90 >? 0  is false. SO Mark this region with an X on your line

Region 2: (-2,0),  

I can choose -1 since its between -2 and 0.

I get:        

(-1)(-1-1)(-1+2) >? 0       I used '?' because I am not sure if it is true

so:  (-1)(-2)(1) >? 0  

Finally   2 >? 0  is True. SO Mark this region with an check mark on your line

Region 3: (0,1),  

I can choose 0.5 since its between 0 and 1.

I get:        

(0.5)(0.5-1)(0.5+2) >? 0       I used '?' because I am not sure if it is true

so:  (0.5)(-0.5)(2.5) >? 0  

Finally   -0.625>? 0  is false. SO Mark this region with an X on your line

Finally:  

Region 4: (1,inf),  

I can choose 5 since its in the region to the right of 1.

I get:        

(5)(5-1)(5+2) >? 0       I used '?' because I am not sure if it is true

so:  (5)(4)(7) >? 0  

Finally   140 >? 0  is true. SO Mark this region with a check on your line

Finally: We have 2 regions that were true (check marks)

Regions 2 and 4:  (-2,0) and (1,inf)

We WRITE them together USING the U (for union)

Final answer:   (-2,0) U (1,inf)

sum of two digits of a 2 digit number is 12. if the digits are reversed, the new number, so formed increase by 36. find the number ​

Answer»

Answer: Tens digit of NUMBER = x

Ones digit of number = 12-x

Original Number = 10x+12-x

= 9x+12

REVERSED Number = 10(12-x)+x

= 120-10x+x

= 120-9x

According to the question,

9x+12+36=120-9x

9x+48=120-9x

9x+9x=120-48

18x=72

x=72/18

x=4

Original Number = 9x+12

= 9(4)+12

= 36+12

= 48 is the number

What are two numbers whose sum is 58 and difference is 28?

Answer»

Step-by-step explanation:

let the numbers be a and B

Now,

a+b = 58 --------1

a-b=28---------2

On subtracting EQ 2 from 1 we get,

a+b=58

- a - b = 28

=> 2b =30

b = 15

On substituting the value of b in eq 2. {you can SUBSTITUTE in any eq.}

a-15=28

a=28+15

a=43

Thus, the REQUIRED numbers are 43 and 15

33.

If the sum of two opposite angles of a parallelogram is 110° , find the measure of each of its angles.​

Answer»

Step-by-step explanation:

In a PARALLELOGRAM, it is known that OPPOSITE angles are equal. If the SUM is 110degrees, each angle should be 110/2=55 degrees.(you got 2 angles already0

also adjacent angles in a parallelogram are supplementary. So other angle will be 180-55=125 degrees. Using the same rule above, you get its opposite angle as the same.

hence the required ANS is 125,125,55,55.

to verify..SUMMATION should be 360 degrees.

18. After 32 years, Rahim will be 5 times as old as he was 8 years ago. How old is Rahim today?​

Answer»

Answer:

please mark me as brainliest

Step-by-step explanation:

RAHIM is 18 years old today.

Let the PRESENT AGE of Rahim be = x yrs

Therefore,

Age of Rahim after 32 years will be = (x+32)

Age of Rahim 8 years ago was = (x-8)  

THUS, as per the question -

= x + 32 = 5 (x-8)

= x + 32 = 5x - 40

= x - 5x = - 40 -32

= -4x = -72

= x = 72/4

= x = 18 years

Thus, the present age of Rahim is 18 yrs

in the expression xy^2 , the value of X and y decreased by 25 percent , the value of expression is ?​

Answer»

Answer:

LET X and Y DENOTE the new values of x and y respectively.

Then, X = 80% of x = 4x5

Y = 80% of y = 4y5

∴XY2=4x5×(4y5)2=4x5×16y25=64125xy2

Decrease in the value :

=(xy2−64125xy2)=61125xy2
