2.

Find the irrational number between 3/5and2/3

Answer»

Step-by-step explanation:

First we will make the DENOMINATOR same as 15.

✓3×3/5=9/15

✓2×5/3×5=10/15

Further we will multiply them by 10 ROB GET greater difference

this gives 90/150 & 100/150

Hence five numbers are

✓91/150,92/150,93/150,95/150&96/150

6.	find the area of a triangular lot with side length 50 meters, 65 meters, and 81 meters (complete solution).
Answer» Given : Sides of the triangular PLOT = 50 m, 65 m and 81 m. To find : AREA of the triangular plot = ? Step-by-step explanation : Now, the formula to find the semi-perimeter of a TRIANGLE is :- $\bigstar {\boxed {\bf S = \dfrac{ a+ b+ c}{2}}}$ Substituting value in above formula, we get $\begin{lgathered} \tt S = \dfrac{ 50 + 65 + 81 }{2}\\ \\ \tt =\dfrac{196}{2}\\ \\ \tt= 196 \div 2\\ \\ \tt= 98 \: m\end{lgathered}$ Now, by HERON's formula find the area of the triangular plot : $\bigstar{\boxed{\bf Area \:of \triangle = {\sqrt{s(s-a) (s-b) (s-c)}}}}$ Substituting value in the above formula, we get, ${\tt = {\sqrt{98(98-50) (98-65) (98-81)}}} \\ \\ \tt = {\sqrt{98\times 48 \times 33 \times 17}} \\ \\ \tt = {\sqrt{2\times7\times7\times2\times2\times2\times2\times3\times3\times11\times17}} \\ \\ \tt = 2 \times 7 \times 2 \times 3{\sqrt{11\times17\times2}} \\ \\ \tt = 84{\sqrt{374}}$ Thus, The Area of the triangular plot $\tt = 84{\sqrt{374\:m^2}}$

6.

find the area of a triangular lot with side length 50 meters, 65 meters, and 81 meters (complete solution).

Answer»

Given :

Sides of the triangular PLOT = 50 m, 65 m and 81 m.

To find :

AREA of the triangular plot = ?

Step-by-step explanation :

Now, the formula to find the semi-perimeter of a TRIANGLE is :-

$\bigstar {\boxed {\bf S = \dfrac{ a+ b+ c}{2}}}$

Substituting value in above formula, we get

$\begin{lgathered} \tt S = \dfrac{ 50 + 65 + 81 }{2}\\ \\ \tt =\dfrac{196}{2}\\ \\ \tt= 196 \div 2\\ \\ \tt= 98 \: m\end{lgathered}$

Now, by HERON's formula find the area of the triangular plot :

$\bigstar{\boxed{\bf Area \:of \triangle = {\sqrt{s(s-a) (s-b) (s-c)}}}}$

Substituting value in the above formula, we get,

${\tt = {\sqrt{98(98-50) (98-65) (98-81)}}} \\ \\ \tt = {\sqrt{98\times 48 \times 33 \times 17}} \\ \\ \tt = {\sqrt{2\times7\times7\times2\times2\times2\times2\times3\times3\times11\times17}} \\ \\ \tt = 2 \times 7 \times 2 \times 3{\sqrt{11\times17\times2}} \\ \\ \tt = 84{\sqrt{374}}$

Thus, The Area of the triangular plot $\tt = 84{\sqrt{374\:m^2}}$

SOLUTION: Case 1 $= ( \sqrt{5} + \sqrt{7} ) {}^{2} \\ = ( \sqrt{5} ) {}^{2} + ( \sqrt{7} ) {}^{2} + 2 \times ( \sqrt{5} \times \sqrt{7} ) \\ = 5 + 7 + 2 \sqrt{5 \times 7} \\ = 12 + 2 \sqrt{35}$ Case 2 $= ( \sqrt{5} + \sqrt{7} ) \times 2 \\ = 2 \times \sqrt{5} + 2 \times \sqrt{7} \\ = 2 \sqrt{5} + 2 \sqrt{7}$ NOTE: I have MADE the POSSIBLE question REGARDING this. Some important formulas: (a+b)²= a²+b²+2ab. (used) (a-b)²= a²+b²-2ab. (a+b)³= a³+b³+3a²b+3ab² (a-b)³= a³-b³-3a²b+3ab²

On simplifying (✓5+✓7)2 we get

Answer»

ANSWER:

Case 1 = 12+2√35

Case 2 = 2√5+2√7

GIVEN:

Case 1 = (√5+√7)²

Case 2 = (√5+√7)2

TO FIND:

Simplify the above expression.

SOLUTION:

Case 1

$= ( \sqrt{5} + \sqrt{7} ) {}^{2} \\ = ( \sqrt{5} ) {}^{2} + ( \sqrt{7} ) {}^{2} + 2 \times ( \sqrt{5} \times \sqrt{7} ) \\ = 5 + 7 + 2 \sqrt{5 \times 7} \\ = 12 + 2 \sqrt{35}$

Case 2

$= ( \sqrt{5} + \sqrt{7} ) \times 2 \\ = 2 \times \sqrt{5} + 2 \times \sqrt{7} \\ = 2 \sqrt{5} + 2 \sqrt{7}$

NOTE:

I have MADE the POSSIBLE question REGARDING this.

Some important formulas:

(a+b)²= a²+b²+2ab. (used)
(a-b)²= a²+b²-2ab.
(a+b)³= a³+b³+3a²b+3ab²
(a-b)³= a³-b³-3a²b+3ab²

43.	If the wages of seven workers is 35,40,45,35,40,35,50 find the modal wage
Answer» Modal wage is 35. Step-by-step EXPLANATION: We are given the wages of seven workers below; 35, 40, 45, 35, 40, 35, 50 We have to find the modal wage from the above data. MODE of the data represents that VALUE which occurs maximum number of times in the data, that is; Suppose if we have 5 data value in which 2 is occurring 3 times, 4 is occurring 1 time and 6 is ALSO occurring 1 time, so the mode of this data will be 2 as it is occurring maximum number of times in the data. Now, according to our question; The value 35 is APPEARING maximum number of times in the data, that is 35 is appearing 3 times. Therefore, the modal wage of the data is 35.

If the wages of seven workers is 35,40,45,35,40,35,50 find the modal wage

Answer»

Modal wage is 35.

Step-by-step EXPLANATION:

We are given the wages of seven workers below;

35, 40, 45, 35, 40, 35, 50

We have to find the modal wage from the above data.

MODE of the data represents that VALUE which occurs maximum number of times in the data, that is;

Suppose if we have 5 data value in which 2 is occurring 3 times, 4 is occurring 1 time and 6 is ALSO occurring 1 time, so the mode of this data will be 2 as it is occurring maximum number of times in the data.

Now, according to our question;

The value 35 is APPEARING maximum number of times in the data, that is 35 is appearing 3 times.

Therefore, the modal wage of the data is 35.

44.	A result of global warming is that ice of some glaciers is melting. Twelve years after the ice disappears, tiny plants called lichen grows approximately in the shape of a circle. The relationship between the diameter of this circle and the age of the lichen can be approximated with the formula d= 7.0 for Where d= diameter of lichen in mm T=number of years after the ice has disappeared a) Using the formula calculate the diameter of the lichen 16 years after the ice disappeared.b) Anne measured the diameter of some lichen and found it was 35mm, how many years ago did the ice disappear at this spot?
Answer» Answer: a) d = 14 mm b) t = 37 years Step-by-step EXPLANATION: a) The correct formula showing the RELATIONSHIP is; d = 7 x √(t - 12) For t is >= 12 Now we have to determine the diameter of lichen after 16 years. Putting the VALUE of t d = 7 x √(16 - 12) d = 7 x √(4) d = 14 mm b) Now we are GIVEN diamtere = 35 35 = 7 x √(t - 12) 5 = √(t - 12) 25 = (t - 12) t = 25 + 12 t = 37 years

Answer»

Answer:

a) d = 14 mm

b) t = 37 years

Step-by-step EXPLANATION:

a) The correct formula showing the RELATIONSHIP is;

d = 7 x √(t - 12)

For t is >= 12

Now we have to determine the diameter of lichen after 16 years. Putting the VALUE of t

d = 7 x √(16 - 12)

d = 7 x √(4)

d = 14 mm

b) Now we are GIVEN diamtere = 35

35 = 7 x √(t - 12)

5 = √(t - 12)

25 = (t - 12)

t = 25 + 12

t = 37 years
