the perimeter of an isosceles triangle is 10 3 by 4 cm if one of its equal side is 2 5 by 6 find the third side​

Answer»

Answer:

The perimeter of an isosceles TRIANGLE =10- 3/4 or we can also WRITE 43/4cm

If one of the EQUAL SIDE is 2-5/6 or 17/6cm

Then the third side will be =43/4-34/6

=(258-136)/24

=122/24

=5-1/12cm.

If 1/a+1/b+1/c =0then a^2+b^2+c^2=​

Answer»

ANSWER:

GIVEN THAT a+B+C =0 -------1²

now, 1/a²+b²+c² + 1/b²+c²-a²  + 1/c²+a²-b²

=1/a²+(b+c)(b-c)  + 1/b²+(c+a)(c-a) + 1/c²+(c+b)(a-b)

=1/a²+(-a)(b-c) + 1/b²+ (-b)(c-a) + 1/c²+ (-c)(a-b)    (from 1)

=1/a(a-b+c) + 1/b(a+b-c) = 1/c(c-a+b)

=1/a(a+c-b) + 1/b(a+b-c) + 1/c(b+c-a)

=1/a(-b-b) + 1/b(-c-c) + 1/ c (-a-a)                             (from

1)

=1/-2ab + 1/-2bc + 1/-2ac 

= 1/-2 (1/ab + 1/bc+ 1/ac )

= -1/2 (a+b+c/abc)

=-1/2 (0)  (from 1)

= 0

Find two integers whose sum is 16 and product is 55

Answer»

Since the sum of the two numbers is 16, let ONE AMONG them be \sf{x}, so that the other will be \sf{16-x.}

Given that their product is 55. Then,

\longrightarrow\sf{x(16-x)=55}

\longrightarrow\sf{16x-x^2=55}

\longrightarrow\sf{x^2-16x+55=0}

\longrightarrow\sf{x^2-11x-5x+55=0}

\longrightarrow\sf{x(x-11)-5(x-11)=0}

\longrightarrow\sf{(x-11)(x-5)=0}

\Longrightarrow\sf{x=11\quad OR\quad x=5}

If \sf{x=11,} then the other number will be \sf{16-11=5.}

If \sf{x=5,} then the other number will be \sf{16-5=11.}

However, \bf{11} and \bf{5} are the numbers.

Two blocks A and B of same masses attatched with a light spring are suspended by a string as shown in figure .Find the acceleration of block A and block B just after cut the string .​

Answer»

Answer :-

\implies \boxed{ \sf{a_{A} = 2g \: or \: 20 \: \frac{m} {{s}^{2} } }} \\ \implies \boxed{ \sf{ a_{B} = 0}} \:

To Find :-

→ Acceleration of block "A" and "B" .

Explanation:-

According to the question -

→ Mass of both blocks is same .

(1) Before cut the string ( refer to attachment )

Before cut the string TENSION (T) , spring force (kx) and gravitational force (mg) is working on block "A" ,

Before cut the string there is no acceleration in both blocks .

hence ,

→ T - kx - mg = 0 .....eq.(1) ( on block A)

and ,

→ kx - mg = 0 ( on block B)

→ kx = mg [ put in eq.(1) ]

→ T - mg - mg = 0

→ T = 2mg

now,

(2) Just after cut the string ( refer to the attachment )

After cutting the string these is Acceleration in both block .( After cut the string Tension is REMOVED on block "A" )

hence ,

\sf{ Let \:acceleration\:of\:block\:A\:is\:a_{A}}\\ \sf{and\:of\:B\:is\:a_{B}}

• On block "B"

\implies \sf{ kx - mg = ma_{B} } \\ \\ \implies \sf{mg - mg =m a_{B} } \\ \\ \implies \boxed{ \sf{ a_{B} = 0}}

• On block "A"

\implies \sf{ mg + kx = ma_{A}} \\ \\ \implies \sf{ma_{A} = 2mg} \\ \\ \implies \boxed{ \sf{a_{A} = 2g \: or \: 20 \: \frac{m} {{s}^{2} } }}

Note - After cut the string these is no normal CONTACT force .( so NEGLECT it )

If a-b = -1 and a-b = -12 ,find a^3 - b^3​

Answer»

Answer:

Step-by-step explanation:

Before going into a representation of the decimal expansion of rational numbers, let US UNDERSTAND what rational numbers are. Any number that can be REPRESENTED in the form of p/q, such that p and q are integers and q ≠ 0 are known as rational numbers. So when these numbers have been simplified further, they result in decimals. Let us LEARN here how to expand such decimals.

EXAMPLES: 6,−8.1,45 etc. are all examples of rational numbers.

एक कार्य 40 दिनों में पूरा करना था तथा इसके लिए 24 आदमी काम पर लगाये गये 28 दिनों के बाद 11 आदमी और काम पर लगा दिए गये।और काम निश्चित समय पर समाप्त हो गया। यदि अतरिक्त आदमी काम पर नही लगाये गये होते ।तो काम कितने दिन विलम्ब से समाप्त होता।​

Answer»

Answer:

Step-by-step explanation:

एक दिन।

मान लीजिए 1 आदमी 1 दिन में 1 यूनिट काम कर सकता है

25 दिन = 750 इकाई में 30 पुरुषों द्वारा किया गया कार्य

काम कुल 37 दिनों में पूरा हो जाता है। इसलिए 35 आदमियों ने 12 और दिनों के लिए काम किया

35 * 12 = 420 यूनिट

अब क्या होगा अगर 5 अतिरिक्त पुरुषों को रोजगार नहीं मिलेगा,

420 इकाइयों (420/30) को पूरा करने में 30 पुरुषों को 14 दिन लगेंगे

30 पुरुषों को 25 + 14 = 39 दिन लगते हैं। वे 38 दिनों में काम करने वाले थे। तो काम में 1 दिन की देरी हो जाती।

ek din.

maan leejie 1 aadamee 1 din mein 1 yoonit kaam kar sakata hai

25 din = 750 ikaee mein 30 purushon dvaara kiya gaya kaary

kaam kul 37 dinon mein poora ho jaata hai. isalie 35 aadamiyon NE 12 aur dinon ke lie kaam kiya

35 * 12 = 420 yoonit

ab kya hoga agar 5 atirikt purushon ko rojagaar NAHIN milega,

420 ikaiyon (420/30) ko poora karane mein 30 purushon ko 14 din lagenge

30 purushon ko 25 + 14 = 39 din lagate HAIN. ve 38 dinon mein kaam karane vaale the. to kaam mein 1 din kee deree ho jaatee.
