If a/b=b/c then solve (a²+ b²+2ab)/(b² +c²+2bc)= a/c.My question was wrong last time now it is correct please show step by step .

Answer»

$\huge\underline\bold\red{Answer:}$

HENCE Proved

$\huge\underline\bold\red{Proof:}$

$\frac{a}{<klux>B</klux>} = \frac{b}{c}$

${b}^{2} = ac$

$b = \sqrt{ac}$

$LHS = \frac{ (a²+ b²+2ab) }{(b² +c²+2bc)}$

Applying the VALUE of b² and b

$= \frac{ {a}^{2} + ac + 2a \sqrt{ac} }{ac + {c}^{2} + 2c \sqrt{ac} }$

$= \frac{a(a + c + 2 \sqrt{ac}) }{c(a + c + 2 \sqrt{ac}) }$

Answer» Answer: 6.6 Step-by-step EXPLANATION: Call his normal time to reach school = T And 8 min = 8/60 hr = (2/15) hr And RATE X time = DISTANCE....so....EQUATING distances we have (9/2)(T + 2/15) = (9/2 +1) ( T - 2/15) (9/2 ) ( T + 2/15) = (11/2) (T - 2/15) (9/2)T + (9/15) = (11/2)T - 11/15 (11/15) + (9/15) = (11/2) T - (9/2)T 20/15 = T = (4/3) hr So...the distance is (9/2) ( 4/3 + 2/15) = (9/2) ( 22/15) = 33/5 km = 6.6 km

8. Aarav walks from his house at 9/2 km/hr andreaches his school late by 8 minutes. Next day,he increases his speed by 1 km/hr and reaches 8minutes before school time. How far is the schoolfrom hishouse?

Answer»

Answer: 6.6

Step-by-step EXPLANATION:

Call his normal time to reach school = T

And 8 min = 8/60 hr = (2/15) hr

And RATE X time = DISTANCE....so....EQUATING distances we have

(9/2)(T + 2/15) = (9/2 +1) ( T - 2/15)

(9/2 ) ( T + 2/15) = (11/2) (T - 2/15)

(9/2)T + (9/15) = (11/2)T - 11/15

(11/15) + (9/15) = (11/2) T - (9/2)T

20/15 = T = (4/3) hr

So...the distance is

(9/2) ( 4/3 + 2/15) =

(9/2) ( 22/15) = 33/5 km = 6.6 km

Answer» Answer : The measure of each adjacent angle :- First adjacent angle = 108° Second adjacent angle = 72° Given : Ratio of two adjacent angles of a parallelogram = 3 : 2 To find : Measure of each angle Concept : As mentioned in the question, the ratio is of two adjacent angles of a parallelogram. And the sum of adjacent angles is EQUAL to 180°. So, FIRSTLY assume the two angles as 3a and 2a. To find the value of 'a' add both the angles and keep them equal to 180°. After getting the value of a, substitute it in both the adjacent angles, the resultant value will be our REQUIRED answer. Solution : Let, First adjacent angle of parallelogram = 3a Second adjacent angle of parallelogram = 2a ★ Sum of angles of adjacent angles of a parallelogram = 180° ➪ 3a + 2a = 180° ➪ 5a = 180° ➪ Transposing 5 to the right hand side. ➪ a = 180° ÷ 5 ➪ a = 36° The value of a = 36° Substituting the value of a in the adjacent angles of parallelogram :- → First adjacent angle = 3a = 3 × 36° = 108° → Second adjacent angle = 2a = 2 × 36° = 72° ━━━━━━━━━━━━━━━━━━━━ VERIFICATION : To verify the value of both the adjacent angles of parallelogram, add both the angles. If they sum upto 180° (∵sum of adjacent angles = 180°) Then their values are right. Measure of the adjacent angles :- The two adjacent angles are 108° and 72°.

the measure of two adjacent angle of a parallelogram are in the ratio 3:2. find the measure of each of the angle of the parallelograms

Answer»

Answer :

The measure of each adjacent angle :-

First adjacent angle = 108°
Second adjacent angle = 72°

Given :

Ratio of two adjacent angles of a parallelogram = 3 : 2

To find :

Measure of each angle

Concept :

As mentioned in the question, the ratio is of two adjacent angles of a parallelogram. And the sum of adjacent angles is EQUAL to 180°. So, FIRSTLY assume the two angles as 3a and 2a. To find the value of 'a' add both the angles and keep them equal to 180°. After getting the value of a, substitute it in both the adjacent angles, the resultant value will be our REQUIRED answer.

Solution :

Let,

First adjacent angle of parallelogram = 3a
Second adjacent angle of parallelogram = 2a

★ Sum of angles of adjacent angles of a parallelogram = 180°

➪ 3a + 2a = 180°

➪ 5a = 180°

➪ Transposing 5 to the right hand side.

➪ a = 180° ÷ 5

➪ a = 36°

The value of a = 36°

Substituting the value of a in the adjacent angles of parallelogram :-

→ First adjacent angle = 3a = 3 × 36° = 108°

→ Second adjacent angle = 2a = 2 × 36° = 72°

━━━━━━━━━━━━━━━━━━━━

VERIFICATION :

To verify the value of both the adjacent angles of parallelogram, add both the angles. If they sum upto 180° (∵sum of adjacent angles = 180°) Then their values are right.

Measure of the adjacent angles :-

The two adjacent angles are 108° and 72°.

Adding both the angles :-

→ 108° + 72°

→ 180°

Sum of adjacent angles = 180°.

HENCE, VERIFIED.

Consider 3-2√7 as a rational number, then we can write it in the form of a/b, where a and b are co prime. 3-2√7 = a/b -2√7 = a/b - 3 -2√7 = (a-3B)/b √7 = (-a+3b)/2b So this PROVES that (3b - a)/2b is a rational number. But √7 is an irrational number so it CONTRADICTS our assumption. So our assumption is wrong. 3-2√7 is an irrational

Show that√3 - 2√7 is anirrational number ?

Answer»

Answer:

Given: The term 3-2- √7.

To find: Prove that 3-2-√7 is an IRRATIONAL

NUMBER.

Solution:

• Now we have given the term: 3 - 2√7

. Consider 3-2√7 as a rational number, then we can write it in the form of a/b, where a and b are co prime.

3-2√7 = a/b

-2√7 = a/b - 3

-2√7 = (a-3B)/b

√7 = (-a+3b)/2b

So this PROVES that (3b - a)/2b is a rational number.

But √7 is an irrational number so it CONTRADICTS our assumption.

So our assumption is wrong.

3-2√7 is an irrational

$\huge\green{\mid{\fbox{{คภรฬєг⤵}}\mid}}$

So that's an AP

a=5

d=10

tn= 995

tn= a+ (n-1)d

995= 5 + (n-1)10

995= 5 + 10n-10

995= -5+10n

Answer» Answer: Introduction: Serum osmolality is an essential laboratory parameter to understand several clinical disorders such as electrolyte disturbances, exogenous intoxication and hydration STATUS. Objective: This study aims to update knowledge about the osmolality examination through research papers published to date. Materials and methods: The survey was conducted on PubMed database. It highlights main concepts, both historical and physiological aspects, and the clinical applications of the serum osmolality test. In addition, an extensive survey of formulas for the serum osmolality calculation was conducted. Discussion: The measurement of serum osmolality is relevant in changes in intracellular and extracellular balance, as a trusted and valuable indicator of solute concentration in the blood. The mathematical equations for serum osmolality calculation acquire relevance in health services where serum is not available, and situations in which calculation of the osmolal gap is necessary, but the variability of the formulas is a significant BIAS. Conclusion: The measurement of serum osmolality is USEFUL in cases of dehydration, sodium and POTASSIUM disorders, glucose alteration, exogenous poisoning, adrenal insufficiency, neurological injury, physical exercise and others.

Answer» Answer: given that x/y=8/20 convert 8/20 to simplest FORM..i.e., 2/5 ∴ the LOGIC we can apply is that if we multiply 2/5 with the same number in the NUMERATOR and denominator we get the answer in which x and y vary directly. So, if we multiply (2/5) with (4/4), we get 8/20. similarly if we multiply 2/5 with 5/5 we will get 10/25. and if we multiply 2/5 with 8/8 we get 16/40. ∴ the first blank can be filled by the no. 25 and the SECOND blank with no. 16.

Find the missing terms in the following tables ,if x and vary directly. x/y=8/20=10/_=___/40

Answer»

Answer:

given that x/y=8/20

convert 8/20 to simplest FORM..i.e., 2/5

∴ the LOGIC we can apply is that if we multiply 2/5 with the same number in the NUMERATOR and denominator we get the answer in which x and y vary directly.

So, if we multiply (2/5) with (4/4), we get 8/20.

similarly if we multiply 2/5 with 5/5 we will get 10/25.

and if we multiply 2/5 with 8/8 we get 16/40.

∴ the first blank can be filled by the no. 25 and the SECOND blank with no. 16.

38.	In a parallelogram abcd, angle d= 140.find the measures of angle a and angle b.
Answer» Answer: angle a = 40 , angle b = 140 Step-by-step explanation: In a parallelogram opposite ANGLES are equal i.e. angle a = angle c ; angle b = angle d and ALSO sum of adjacent angles = 180. angle a + angle b = 180 ; angle c + angle d = 180 So, angle b = angle d = 140 and angle a + angle b = 180 angle a + 140 = 180 angle a = 180 - 140 angle a = 40.

38.

In a parallelogram abcd, angle d= 140.find the measures of angle a and angle b.

Answer»

Answer:

angle a = 40 , angle b = 140

Step-by-step explanation:

In a parallelogram opposite ANGLES are equal i.e.

angle a = angle c ; angle b = angle d

and ALSO sum of adjacent angles = 180.

angle a + angle b = 180 ; angle c + angle d = 180

So,

angle b = angle d

= 140

and

angle a + angle b = 180

angle a + 140 = 180

angle a = 180 - 140

angle a = 40.

Answer» Answer: Let AB = x, BD = y and BC = Z. From triangle ABC, {x}^{2} + {z}^{2} = {(4 + 5)}^{2} = 81 - - (1) From triangle ADB, {x}^{2} = {y}^{2} + 16 - - - (2) From triangle BDC, {z}^{2} = {y}^{2} + 25 - - - (3) Substituting (2) and (3) in (1), ( {y}^{2} + 16) + ( {y}^{2} + 25) = 81 \\ {y}^{2} = 20 - - - (4) \\ y = 2 \sqrt{5} Substituting (4) in (2), {x}^{2} = 20 + 16 \\ x = 6 Thus BD = 2√5; AB = 6

43.

In a triangle ABC right angled at B and BD perpendicular to AC if AD=5cm CD=6cm find BD AB

Answer»

Answer:

Let AB = x, BD = y and BC = Z.

From triangle ABC,

{x}^{2} + {z}^{2} = {(4 + 5)}^{2} = 81 - - (1)

From triangle ADB,

{x}^{2} = {y}^{2} + 16 - - - (2)

From triangle BDC,

{z}^{2} = {y}^{2} + 25 - - - (3)

Substituting (2) and (3) in (1),

( {y}^{2} + 16) + ( {y}^{2} + 25) = 81 \\ {y}^{2} = 20 - - - (4) \\ y = 2 \sqrt{5}

Substituting (4) in (2),

{x}^{2} = 20 + 16 \\ x = 6

Thus BD = 2√5; AB = 6
