1.

how many terms of the arithmetic progression 25,22,19 are needed to give the sum of 116 also find the last term.

Answer»

Answer:

We KNOW the formula that sn= n/2 [2a +(n-1) d]

Sn= 116

a= 25

d=22-25 =-3

n=?

116= n/2 [2×25 +(n-1) -3]

232= n[50-3n+3]

232=53n-3n^2

3n^2-53n+232= 0

3n^2-24n-29n+232=0

3n(n-8)-29(n-8)=0

(n-8) (3n-29) =0

n=8

Hence the number of terms of AP is 8.

Hope it helps.

16.

the perimeter of a right angled triangle is 70units and its hypotenus is 29 units find the length of other side

Answer»

$\large{\underline{\red{\rm{AnswEr:21\: units\:\:20\: units}}}}$

$\huge\bold\purple{\underline{Solution:}}$

$\bold\green{\underline{Given:}}$

The perimeter of Triangle=70units

The hypotenous of Triangle=29 units

$\bold\red{\underline{Let:}}$

The other two sides be X and Y

$\bold\orange{\underline{A.T.Q}}$

Using, pathagoras theorem,

⟹Hypotenus²=Perpendicular²+base²

⟹29²=X²+Y²-------(1)

$\bold\purple{\boxed{Perimeter\:of\: Triangle=Sum\:of\: it's\: sides}}$

⟹70=X+Y+29

⟹70-29=X+Y

⟹41=X+Y---------(2)

⟹Y=41-X

Using, substituting method here

Now, putting the value of Y=41-X in EQ 1

⟹29²=X²+Y²

⟹29²=X²+(41-X)²

⟹841=X²+1681-82X+X²

⟹841=1681-82X+2X²

⟹2X²-82X+840=0

Dividing by 2 on both sides

⟹X²-41X+420=0

Splitting the middle term here

⟹X²-20X-21X+420=0

⟹X(X-20)-21(X-20)=0

⟹(X-21)(X-20)=0

Therefore, X-21=0 X=21 X-20=0 X=20

Putting the value of X=21 in EQ 2

⟹41=X+Y

⟹41=21+Y

⟹Y=41-21

⟹Y=20

Hence,

The other two sides are 21units and 20units

48.	Find the amount and the compound intrest on 8000 at 5 % per annum for 2 yrs
Answer» Answer: Step-by-step explanation: FORMULA For compound interest $C.A= Principal(1+\frac{Rate}{100} )^{Time}$ So, I am Given that:- Principal= 8000* Rate=5 % p.a Time= 2 years To find Amount Compound Interest Solution By using the above formula $C.A=8000*(1+\frac{5}{100} )^{2}$ So, I GET my Compound Interest as 9724.05 Also we know that $Amount = C.A - Principal$ So, Amount= 9724.05-8000 Amount= 1724.05

48.

Find the amount and the compound intrest on 8000 at 5 % per annum for 2 yrs

Answer»

Answer:

Step-by-step explanation:

FORMULA For compound interest

$C.A= Principal*(1+\frac{Rate}{100} )^{Time}$

So, I am Given that:-

Principal= 8000

Rate=5 % p.a

Time= 2 years

To find

Amount
Compound Interest

Solution

By using the above formula

$C.A=8000*(1+\frac{5}{100} )^{2}$

So, I GET my Compound Interest as 9724.05

Also we know that

$Amount = C.A - Principal$

So, Amount= 9724.05-8000

Amount= 1724.05
