The second term of the ap is 13 and 5th term is 25,then 7th term is

Answer»

$\rule{250}3$

$\huge\sf\red{Given\::}$

$\leadsto\:\sf a_{2} = a + d$

$\leadsto\:\sf a_{5} = a + 4d$

$\leadsto\:\sf a + d = 13$ _______①

$\leadsto\:\sf a + 4d = 25$ _______②

$\rule{250}3$

$\huge\sf\pink{Solution\::}$

$\sf\orange{From\: equation\:(1)\:\&\:(2)\::}$

$\implies\sf a + 4d = 25$

$\implies\sf a + d = 13$

$\implies\sf 3d = 12$

$\implies\sf d =\dfrac{\cancel{12}}{\cancel{3}}$

$\implies\sf d\:=\;4$

$\rule{150}2$

$\small\sf\purple{Substituting\:x\: value\:in\; Equation\;(1)}$

$\longrightarrow\:\sf a + d = 13$

$\longrightarrow\:\sf a + 4 = 13$

$\longrightarrow\:\sf a = 13 - 4$

$\longrightarrow\:\sf a = 9$

$\rule{150}2$

$\small\sf\blue{Finding\: 7^{th}\: Term}$

$\dashrightarrow\:\sf a_{7} = a + 6d$

$\dashrightarrow\:\sf a_{7} = a + 6(4)$

17055.	In fig BD perpendicular to AC. angle DCB=30 and angle EAC=50 find x and y
Answer» Answer: Step-by-step EXPLANATION: In triangle AFD, angle AFD = 180 - (FAD - FDA) = 180 - ( 90 - 50 ) = 40 DEG At point F, angle AFD = BFE = 40 deg Angle x can be found in two ways. but we do one way. in triangle EAC, angle AEC = 180 - angle EAC - angle ECA = 180 - 50 - 30 = 100 deg So angle AEB = x = 180 - 100 deg = 80 deg Now in triangle BFE, x + y + 40 = 180 as x = 80, 80 + y + 40 = 180 y = 60

17055.

In fig BD perpendicular to AC. angle DCB=30 and angle EAC=50 find x and y

Answer»

Answer:

Step-by-step EXPLANATION:

In triangle AFD, angle AFD = 180 - (FAD - FDA) = 180 - ( 90 - 50 ) = 40 DEG

At point F, angle AFD = BFE = 40 deg

Angle x can be found in two ways. but we do one way.

in triangle EAC, angle AEC = 180 - angle EAC - angle ECA

= 180 - 50 - 30 = 100 deg

So angle AEB = x = 180 - 100 deg = 80 deg

Now in triangle BFE, x + y + 40 = 180

as x = 80, 80 + y + 40 = 180

y = 60

Answer» Let's solve your equation step-by-step. $50=20+(\frac{305+8f}{120} )\times 5$ Step 1: Simplify both sides of the equation. $50=20+(\frac{305+8f}{120} )( 5)$ (DISTRIBUTE) $50=20+\frac{1}{3}f+\frac{305}{24}$ (Combine Like TERMS) $50=(\frac{1}{3}f)+(20+\frac{305}{24})$ $50=\frac{1}{3}f+\frac{785}{24}$ Step 2: Flip the equation. $\frac{1}{3}f+\frac{785}{24}=50$ Step 3: SUBTRACT $\frac{785}{24}$ from both sides. $\frac{1}{3}f+\frac{785}{24}-\frac{785}{24}=50-\frac{785}{24}$ $\frac{1}{3}f=\frac{415}{24}$ Step 4: Multiply both sides by 3. $3\times \frac{1}{3}f=3\times \frac{415}{24}$ $f=\frac{415}{8}$ Verification $50=20+(\frac{305+8f}{120} )\times 5$ Let's give f its value and solve. So $f=\frac{415}{8}$ . $20+(\frac{305+\left(8\times \frac{415}{8}\right)}{120})\times 5$ $20+\frac{305+415}{120}(5)$ $20+\frac{720}{120}(5)$ $20+(6)(5)$ $20+30$ $50$ ∴ $f=\frac{415}{8}$ in the equation ⇒ $50=20+(\frac{305+8f}{120} )\times 5$ Additional Information ❤ What is an equation?

17056.

Find F in the given equation.

Answer»

Let's solve your equation step-by-step.

$50=20+(\frac{305+8f}{120} )\times 5$

Step 1: Simplify both sides of the equation.

$50=20+(\frac{305+8f}{120} )( 5)$

(DISTRIBUTE)

$50=20+\frac{1}{3}f+\frac{305}{24}$

(Combine Like TERMS)

$50=(\frac{1}{3}f)+(20+\frac{305}{24})$

$50=\frac{1}{3}f+\frac{785}{24}$

Step 2: Flip the equation.

$\frac{1}{3}f+\frac{785}{24}=50$

Step 3: SUBTRACT $\frac{785}{24}$ from both sides.

$\frac{1}{3}f+\frac{785}{24}-\frac{785}{24}=50-\frac{785}{24}$

$\frac{1}{3}f=\frac{415}{24}$

Step 4: Multiply both sides by 3.

$3\times \frac{1}{3}f=3\times \frac{415}{24}$

$f=\frac{415}{8}$

Verification

$50=20+(\frac{305+8f}{120} )\times 5$

Let's give f its value and solve. So $f=\frac{415}{8}$ .

$20+(\frac{305+\left(8\times \frac{415}{8}\right)}{120})\times 5$

$20+\frac{305+415}{120}(5)$

$20+\frac{720}{120}(5)$

$20+(6)(5)$

$20+30$

$50$

∴ $f=\frac{415}{8}$ in the equation ⇒ $50=20+(\frac{305+8f}{120} )\times 5$

Additional Information ❤

Prove that √7 is irrational

Answer»

a rational number is a number which in which both numerator and denominator BELONG to integers, both the numbers are coming prime, denominator is not equal to 0, it should be in p/q FORM.

Step-by-step EXPLANATION:

assume √7 as a rational number

a/b=√7

a=(√7)*b

squaring both sides

a square= (√7)square*b square

a square=7b square

a square is divisible by 7

then a is also divisible by 7

a=7c

squaring both sides

a square=7 square*c square

a square=49*c square

7b square=49c square

b square=49c square/7

b square=7c square

a and b are not Co-prime so it is not a rational number.

THEREFORE it is a irrational number.

this contraductory has arised DUE to our wrong assumption that√7 is a rational number.

Answer» Answer: Amount she started with is exactly Rs 15. Amount she spend is exactly Rs 10.2 Step-by-step EXPLANATION: Let x = Number of 1 rupee notes y = Number of 20 peise coin. Given Amount she ORIGINALLY started with = Rs 15(Not Exact) Amount left after shopping = 15/3 = Rs 5(Not Exact) Equations She started with Rs 15, so 1.x + 0.2y = 15(Not Exact) .............(1) After shopping, she is left with as many ONE rupee note as she originally had and as many 20 peise coin as she had one rupee note. Hence 1.x + 0.2x = 5(Not Exact) .............(2) Calculation Equation (2) gives 1.2x = 5 ⇒ x = 5/1.2 = 50/12 = 25/6(Not Exact) Since x is an integer and is not exactly equal to 25/6, we take the nearest integral value of 25/6. ⇒ x = 24/6 = 4 Therefore, amount she is left with = 1x + 0.2x = 1.2x = 1.24 = Rs 4.8* Substituting value of x in (1) we get 4 + 0.2y = 15 ⇒ 0.2y = 15-4 = 11 ⇒ y = 11/0.2 = 110/2 ⇒ y = 55 Since no approximation is done to find an integral solution of y, Amount she started with is exactly Rs 15 Amount she spend is 15 - 4.8i.e Rs 10.2

Answer»

Answer:

Amount she started with is exactly Rs 15.

Amount she spend is exactly Rs 10.2

Step-by-step EXPLANATION:

Let

x = Number of 1 rupee notes

y = Number of 20 peise coin.

Given

Amount she ORIGINALLY started with = Rs 15(Not Exact)

Amount left after shopping = 15/3 = Rs 5(Not Exact)

Equations

She started with Rs 15, so

1.x + 0.2y = 15(Not Exact) .............(1)

After shopping, she is left with as many ONE rupee note as she originally had and as many 20 peise coin as she had one rupee note. Hence

1.x + 0.2x = 5(Not Exact) .............(2)

Calculation

Equation (2) gives

1.2x = 5

⇒ x = 5/1.2 = 50/12 = 25/6(Not Exact)

Since x is an integer and is not exactly equal to 25/6, we take the nearest integral value of 25/6.

⇒ x = 24/6 = 4

Therefore, amount she is left with

= 1x + 0.2x

= 1.2x

= 1.2*4

= Rs 4.8

Substituting value of x in (1) we get

4 + 0.2y = 15

⇒ 0.2y = 15-4 = 11

⇒ y = 11/0.2 = 110/2

⇒ y = 55

Since no approximation is done to find an integral solution of y, Amount she started with is exactly Rs 15

Amount she spend is 15 - 4.8i.e Rs 10.2

Factorising is the reverse of expanding brackets, so it is, for example, putting 2x² + X - 3 into the form (2x + 3)(x - 1). This is an important way of solving quadratic equations. The first STEP offactorising an expression is to 'take out' any common factors which the TERMS have.
