3.	the two legs of a triangle are equal and the square of its hypotenuse is 50 find the length of each leg
Answer» LET the length of two legs be ' X ' and that of Hypotenuse be y. Applying Pythagoras Theorem we get, x² + x² = y² We know y² = 50 Substituting it in the above equation we get, x² + x² = 50 2x² = 50 x² = 50 / 2 = 25 => x = √ 25 = 5 units. Hence the length of each side other than hypotenuse is 5 units and that of hypotenuse is √ 50.

3.

the two legs of a triangle are equal and the square of its hypotenuse is 50 find the length of each leg

Answer»

LET the length of two legs be ' X ' and that of Hypotenuse be y.

Applying Pythagoras Theorem we get,

x² + x² = y²

We know y² = 50

Substituting it in the above equation we get,

x² + x² = 50

2x² = 50

x² = 50 / 2 = 25

=> x = √ 25 = 5 units.

Hence the length of each side other than hypotenuse is 5 units and that of hypotenuse is √ 50.

Find next 3 terms of AP:

Answer»

HEY friend,

_____________________________________________________________

$1^2 , 5^2 , 7^2 , 73 ........$ AP is

Common DIFFERENCE (d) = 73 - 49 = 49 - 25 = 24

First term (a) = 1

5th term = a + (n-1)d

= 1 + (5-1)*24

= 1 + 4*24

= 1 + 96

= 97

6th term = 1 + (6-1)*24

= 1 + 5*24

= 1 + 120

= 121

7th term = 1 + (7-1)*24

= 1 + 6*24

= 1 + 144

= 145

Next three terms of AP will be 1 , 25 , 49 , 73 , 97 , 121 , 145 ........

Answer» let 1 kg sugar be x , and 1 kg rice be y 5x+7y = 153 7X + 5Y = 147 12 x + 12Y = 153 + 147 12x + 12y = 300 x + 12y = 300/12 x + 12 y = 25 x + y = 25/12 x+y = 2.5 price of 6 kg sugar and 10 kg rice = 2.5 * 6 * 10 = 150

11.

the cost of 5 kg of sugar and 7 kg of rice is rupees 153 and the cost of 7 kg of sugar and 5kg of rice is rupees 147 find the cost of 6 kg of sugar and 10 kg of rice

Answer»

let 1 kg sugar be x , and 1 kg rice be y

5x+7y = 153

7X + 5Y = 147

12 x + 12Y = 153 + 147

12x + 12y = 300

x + 12y = 300/12

x + 12 y = 25

x + y = 25/12

x+y = 2.5

price of 6 kg sugar and 10 kg rice = 2.5 * 6 * 10 = 150

Answer» When we will divide 100056 by 23 then we will get quotient = 4350 and REMAINDER = 6 Now 4350 * 23 = 100050 So the NEXT number be completely divisible by 23 WOULD be 100073 but we have 100056 as our number, So 100073 - 100056 = 17 So we have 17 as the least number to be added to 100056 to make it completely divisible by 23

30.

I need to know the working as how we arrived at answer 17 for question that what should be added to 100056 to get number completely divisible by 23

Answer»

When we will divide 100056 by 23 then we will get quotient = 4350

and REMAINDER = 6

Now 4350 * 23 = 100050

So the NEXT number be completely divisible by 23 WOULD be 100073

but we have 100056 as our number,

So 100073 - 100056 = 17

So we have 17 as the least number to be added to 100056 to make it completely divisible by 23

38.

The average age of 50 pupils in a clss is 10.5.if the class teacher is included,the average increases by 5.then the age of the class teacher is

Answer»

Solution:

_______

Average age = 10.5

Sum of total age of the 50 students = 50 x 10.5 = 525

After including the teacher

total strength = 51

new average = 10.5 + 0.5 = 11

sum of total age of all 51 = 51 x 11 = 561

the age of teacher = 561 - 525 = 36

So, the age of the teacher is 36 years

Note: I have MADE a correction in the given question by taking numeral 5 as 0.5.

Pranav took a loan of $1800 with a rate of simple interest that was 3 times the time period in years. At the end of the time period, Pranav paid a total interest of $216. What was the time period and rate of interest per annum?

Answer»

P = 1800$

T = 3R

SI = 216$

SI = (P*T*R)/100

216 = (1800*3R*R)/100

216 = 18 * 3R * R

216/18 = 3*R^2

12 = 3* R^2

4 = R^2

R = SQRT(4)

R = 2%

T = 3R

T = 3*2

T = 6 YEARS

Rate of interest per annum = 2%

Time period = 6 years.
