3.

a pullover is on sale for Rs 280 in a sport store display 30% discount on all items at what price was the pullover begin sold before the discount

Answer»

GIVEN,

SP = RS. 280

D% = 30%

MP = ?

WE KNOW THAT,

SP = (1-(D%/100))*MP

280 = (1-(30/100))*MP

280 = (70/100)*MP

MP = ((280*100)/70)

MP = Rs. 400

Please let me know if the answer is correct.

5.	how to find the value of cos 5.37 radians give stepwise answer ( calculator se to mujhe bhi karna aata Hai :)
Answer» For COS(5.37) radian first we will get SIN(5.37) radian So => sin(5.37) = -0.79154 => sin(5.37) radian = -0.79154 The sin of 5.37 radian is -0.79154 the same as sin of 5.37 degree . To change 5.37 radian to degree multiply 180/pi = 307.67834 degree . => sin(5.37) radian = -0.79154 _-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_ NOW TRIGONOMETRIC IDENTITY :- $= > {sin}^{2} \alpha + {cos}^{2} \alpha = 1 \\ \\ so \\ \\ = > {sin}^{2} 5.37(radian) + {cos}^{2} 5.37 (radian) = 1 \\ \\ = > {cos}^{2} 5.37(radian) = 1 - {sin}^{2} 5.37(radian) \\ \\ = > cos5.37(radian) = \sqrt{1 - {sin}^{2}5.37(radian) } \\ \\ = > cos5.37(radian) = \sqrt{1 - {( - 0.79145)}^{2} } \\ \\ = > cos5.37(radian) = \sqrt{1 - {(0.79145)}^{2} }$ _______________________[ANSWER] ===================================== DEVIL_KING ▄︻̷̿┻̿═━一

7.	in a two digit number the digit in the unit place is twice of the digit in the tenth place . if the digits are reversed the new number is 27 more than the given number. find the number
Answer» LET the tens digit be x and the UNITS digit be y. So the number be =10x+y A.q. =>y=2x (equation 1) Also,(10y+x)-(10x+y)=27 =>10y+x-10x-y=27 =>9y-9x=27 =>9(y-x)=27 =>y-x=27/9 =>y-x=3 From equation 1 y=2x And y=2(1)=2 So the number is 12.

12.	HiiFind the order of given Differential equation :-y = A sinx + B cos(x+c)__________________need a proper solution no spam :)
Answer» $\bold{Answer :}$ Given that, y = A sinx + B cos (x + c) ...(i) To find the required differential equation and its order, we need to eliminate the ARBITRARY constants A, B and c So, DIFFERENTIATING both sides of (i) with respect to x, we get dy/dx = d/dx {A sinx + B cos (x + c)} ⇒ dy/dx = d/dx (A sinx) + d/dx {B cos (x + c)} ⇒ dy/dx = A cosx - B sin (x + c) ...(ii) Here, d/dx (sinx) = cosx d/dx (cosx) = - sinx d/dx {k f(x)} = k d/dx {f(x)}, where k is any constant d/dx {sin (MX + c)} = m cos (mx + c) d/dx {cos (mx + c)} = - m sin (mx + c) d/dx (u + V) = du/dx + dv/dx, where u and v are functions of x Again, differentiating both sides of (ii) with respect to x, we get d/dx (dy/dx) = d/dx {A cosx - B sin (x + c)} ⇒ d²y/dx² = d/dx (A cosx) - d/dx {B sin (x + c)} = - A sinx - B cos (x + c) = - {A sinx + B cos (x + c)} = - y, using (i) no. equation ⇒ d²y/dx² + y = 0 ...(iii) which is the required differential equation The order of the differential equation (iii) is 2 because the HIGHEST order of the derivative term d²y/dx² is 2 # $\bold{MarkAsBrainliest}$

45.	a can complete a piece of work in 8 hours b can complete in 10 hours and c in 12 hours. if a b c start the work together but a leaves after 2 hours. find the time taken by b and c to complete the remaining work.
Answer» TOTAL unit work = 1/8 + 1/10 + 1/12 = (15 + 12 + 10)/120 = 37/120 Work done by all three in 2 hours = 237 / 120 = 74/120 Remaining work = 1 - (74/120) = 120 - 74 / 120 = 46/120 = 23/60 Now work done by B and C in 1 day = 1/10 + 1/12 = (6 + 5) / 60 = 11/60 So B and C will take = 60/11 23/60 = 23/11 days

45.

a can complete a piece of work in 8 hours b can complete in 10 hours and c in 12 hours. if a b c start the work together but a leaves after 2 hours. find the time taken by b and c to complete the remaining work.

Answer»

TOTAL unit work = 1/8 + 1/10 + 1/12 = (15 + 12 + 10)/120 = 37/120

Work done by all three in 2 hours = 2*37 / 120 = 74/120

Remaining work = 1 - (74/120) = 120 - 74 / 120 = 46/120 = 23/60

Now work done by B and C in 1 day = 1/10 + 1/12 = (6 + 5) / 60 = 11/60

So B and C will take = 60/11 * 23/60 = 23/11 days
