Answer» Correct Question :
GIVEN :
TO FIND :
SOLUTION :Distance between school and house : ➨ 1km + 875 m. ➨ 1000 m + 875 m (1 km = 1000 m) ➨ 1875 m Distance covered each day : ➨ 1875 × 2 ➨ 3750 m Distance covered in 6 days : ➨ 3750 × 6 ➨ 22500 m Therefore, total distance covered in 6 days is 22,500 m. Converting in kilometer :➨ 1000 m = 1 km ➨ 1 m = 1/1000 km ➨ 22500 m = 22500/1000 km ➨ 22500 m = 22 km 500 m Hence, the total distance is 22 km 500 m. |

Two supplimentry angles are such that one is two-third of another. find them |
|
Answer» They are supplement MEANS x+y=180 ∘
Now one angle is two third of another which means x=2y/3 PUTTING in to equation 2y/3 +y=180 ∘
⇒ 2y+3y/3=180 ∘
⇒5y=180×3 ⇒y= 180×3/5
⇒y=108 y=108 x= 2y/3
= 2⋅108/3
=72 ∴x=72 and y=108. |

Show that each of the following numbers is a perfect square . in each case , find the number whose square is the given number1 12252 59263 8281 |
|
Answer» Step-by-step explanation: A perfect square can always be expressed as a product of equal FACTORS. (i) Resolving into prime factors: 441=49×9=7×7×3×3=7×3×7×3=21×21=(21)2 Thus, 441 is a perfect square. (II) Resolving into prime factors: 576=64×9=8×8×3×3=2×2×2×2×2×2×3×3=24×24=(24)2 Thus, 576 is a perfect square. (iii) Resolving into prime factors: 11025=441×25=49×9×5×5=7×7×3×3×5×5=7×5×3×7×5×3=105×105=(105)2 Thus, 11025 is a perfect square. (iv) Resolving into prime factors: 1176=7×168=7×21×8=7×7×3×2×2×2 1176 cannot be expressed as a product of two equal NUMBERS. Thus, 1176 is not a perfect square. (v) Resolving into prime factors: 5625=225×25=9×25×25=3×3×5×5×5×5=3×5×5×3×5×5=75×75=(75)2 Thus, 5625 is a perfect square. (vi) Resolving into prime factors: 9075=25×363=5×5×3×11×11=55×55×3 9075 is not a product of two equal numbers. Thus, 9075 is not a perfect square. (vii) Resolving into prime factors: 4225=25×169=5×5×13×13=5×13×5×13=65×65=(65)2 Thus, 4225 is a perfect square. (viii) Resolving into prime factors: 1089=9×121=3×3×11×11=3×11×3×11=33×33=(33) |

In right triangle ABC, right angled at C, M is the mid-point of hypotenuse AB. C is joined to M and produced to a point D such that DM = CM. Point D is joined to point B.Show that: (i) ΔAMC ≅ ΔBMD (ii) ∠DBC is a right angle. (iii) ΔDBC ≅ ΔACB (iv) CM = 1/2AB Please give me the answer,urgently needed |
|
Answer» Solution:- (i) In ΔAMC and ΔBMD, AM = BM (M is the mid-point of AB) ∠AMC = ∠BMD (Vertically opposite angles) CM = DM (Given) ∴ ΔAMC ≅ ΔBMD (By SAS congruence RULE) And, ∠ACM = ∠BDM (By CPCT) (ii) ∠ACM = ∠BDM However, ∠ACM and ∠BDM are alternate interior angles. Since alternate angles are equal, It can be said that DB || AC
iii) In ΔDBC and ΔACB, DB = AC (Already proved) ∠DBC = ∠ACB (Each 90) BC = CB (Common) ∴ ΔDBC ≅ ΔACB (SAS congruence rule) (iv) ΔDBC ≅ ΔACB ∴ AB = DC (By CPCT)
