1) 0.62² = 0.38442) cost price = Sp - gain%sp = (448- 0.12*448) =394.24

3) (p-9)(p+2) = p²+2p-9p-18 = p²-7p-184) ordinate of a point is the value of its y co-ordinate

if angle A is = 90° , then using Pythagoras theorem

a² = b²+c²

=> c² = a²-b² = (25)²-(7)² = 625-49= 574 => c = 24cm

now, assuming angle c is at base

so, cosC = 7/25 , sinC = 24/25 , tanC = 24/7

similarly cosB = 24/25, sinB = 7/25 , tanB = 7/24

3x + 4y = 10 2x - 2y = 2 3x + 4y + 4x - 4y = 10 + 4 7x = 14 x = 2 3(2) + 4y = 10 6 + 4y = 10 4y = 4 y = 1

Length of the room = 10mBreadth of the room= 7.5m

Area of the room = lxb = 10 x 7.5 = 75m^2

Now, 75 / 1.25 = 60m^2 area covered by carpet width

cost of onem^2 =250∴ cost of 60 m^2 = 250 x 60 = Rs 1500

Angle-Side-Angle (ASA) Rule. Angle-side-angle is a rule used to prove whether a given set of triangles are congruent. If two angles and the included side of one triangle are equal to two angles and included side of another triangle, then the triangles are congruent.

Using this we can say that ADB is congruent to ADC

write in simple word

please

let x= k, y= 3k and z=5kSo, x+y+z = 90°hence, k+3k+5k=90°which gives k= 10°So, x= k= 10° y= 3k= 30° z=5k= 50°

Given is graph of x = 5

Present time is 2:tMinutes required for time to be 3 pm = t^2 /4 - 3

Then,t + t^2/4 - 3 = 604t + t^2 - 12 = 240t^2 + 4t - 252 = 0t^2 + 18t - 14t - 252 = 0t(t + 18) - 14(t + 18)= 0(t - 14)(t +18)=0t = 14, - 18

As t can not be negativeSo value of t = 14

Given time needed by the minutes hand show (t2/4) – 3Hence the quadratic equation becomes, (t2/4) – 3 = 60 – t(t2– 12)/4 = 60 – t(t2– 12) = 240 – 4 tt2– 12 – 240 + 4 t = 0t2+ 4t – 252 = 0t2+ 18t – 14t – 252 = 0t(t + 18) – 14(t + 18) = 0(t + 18)(t – 14) = 0(t + 18) = 0 or (t – 14) = 0∴t = - 18 or t = 14Since t cannot be negative, t = 14

6b is the correct answer

3√3 is Right answer........

No tangent line can be drawn through a point within a circle, since any such line must be a secant line. However,twotangent lines can be drawn to a circle from a pointPoutside of the circle.

Your answer is right bro 👍👍
