asha and sameule have book shelves of the same size partly feild with books . asha's shelf is full and sameule is also full . whose book shelf is more feild and by what fraction . |
|
Answer» Fraction of BOOKS in ASHA’s shelf =5/6 Fraction of books in Samuel’s shelf =2/5 We COMPARE the fractions to find WHOSE shelf is more full. LCM of 5 & 6 is 30 5/6 =5×5/5×6 =25/30 2/5 =2×6/5×6 =12/30 25/30>12/30 ⇒ 5/6>2/5 So, Asha’s shelf has more books and is more full. 5/6−2/5 =5×5/6×5−2×6/5×6 =25/30−12/30 =13/30 Asha’s shelf is more full and by =13/30 |

a train cover a distance of 90 km at a uniform speed had the speed been 15 km/h more, it could have taken 30 min less for the journey . find the original speed of the train |
|
Answer» Answer:1)distance covered = 90 km let the speed of the TRAIN = x km/hr time (t1 ) = distance /speed t1 = 90/x -----(1) 2) distance = 90 km speed = (x+15) km/hr t2 = 90 /(x+15) ----(2) given t1-t2 = 30 minutes 90/x - 90 / (x+15) = 1/2 hr [90(x+15) -90x]/x(x+15) = 1/2 [90x + 1350 -90x]/ (x^2+15X) =1/2 1350 *2= x^2+15x 2700 = x^2+15x x^2+15x-2700=0 x*x +60x -45x - 45*60=0 x(x+60) - 45(x+60)=0 (x+60)(x-45)=0 x+60=0 or x-45=0 x= -60 0r x= 45 x should not be NEGATIVE x= 45 therfore speed of the trainick to let others know, how helpful is it Answer:2 → Original speed of the train = 45 km/hr . Step-by-step EXPLANATION: Given:- → Distance = 90 km . Let the original speed of the train = x km/h . → Time taken to travel = 90/x hr . ∴ Then, new speed = ( x + 15 ) km/hr . ∵ Time taken to travel = 90/( x + 15 ) hr . Now, A/Q, ∵ 90/x = 90/( x + 15 ) + 1/2 . ⇒ 90/x - 90/( x + 15 ) = 1/2 . ⇒ 90[ 1/x - 1/( x + 15 )] = 1/2 . ⇒ x + 15 - x/x( x + 15 ) = 1/2 × 1/90 . ⇒ 15/x( x + 15 ) = 180 . ⇒ x( x + 15 ) = 15 × 180 = 2700 . ⇒ x² + 15x - 2700 = 0 . ⇒ x² + 60x - 45x + 2700 = 0 . ⇒ ( x + 60 )( x - 45 ) = 0 . ⇒ x + 60 = 0 or x - 45 = 0 . ⇒ x = 45 or - 60 . [ ∵ Speed can't be negative. ] ∴ Original speed = 45km/hr . Hence, it is solved . THANKS . |

Geometry construction with compass and straightedge or ruler or ruler Step 1 From point A, draw a line segment at an angle to the given line, and about the same length. The exact length is not important. Geometry construction with compass and straightedge or ruler or ruler Step 2 Set the compasses on A, and set its width to a bit less than one FIFTH of the length of the new line. Geometry construction with compass and straightedge or ruler or ruler Step 3 Step the compasses along the line, marking off 5 arcs. Label the last one C. Geometry construction with compass and straightedge or ruler or ruler Step 4 With the compasses' width set to CB, draw an arc from A just below it. Geometry construction with compass and straightedge or ruler or ruler Step 5 With the compasses' width set to AC, draw an arc from B crossing the one drawn in step 4. This intersection is point D.

Tofees are bought at ₹2 for a rupee and sold at 5 for ₹3. Find the gain or loss per cent. |
|
Answer» GIVEN : Toffees are bought at 2 for a RUPEE and sold at 5 for Rs 3. To find : find the gain or loss percent Solution : Finding the CP of 1 toffee :- 2 toffees = ₹ 1 1 toffee = 1/2 = ₹ 0.5 Finding the SP of 1 toffee :- 5 toffees = ₹ 3 1 toffee = 3/5 = ₹ 0.6. CP = ₹ 0.5 and SP = ₹ 0.6 SP is more so Gain occurred. Finding the Gain :- Gain = SP - CP Gain = 0.6 - 0.5 Gain = 0.1. Finding Gain Percentage :- Gain percentage = (Gain/CP) X 100 Gain Percentage = (0.1/0.5) x 100 Gain Percentage = 20 % HENCE, Gain Percentage = 20 % |

Tan 4 A = cot(A-20) find 3A |
|
Answer» GIVEN : Tan 4A = Cot(A - 20) Convert Tan 4A in the FORM of Cot using IDENTITIES. Cot ( 90 - 4A ) = Cot ( A - 20 ) [ Tan Ø = Cot ( 90 - Ø ) Cancel Cot on the both sides. Cot ( 90 - 4A) = Cot ( A - 20 ) 90 - 4A = A - 20 90 + 20 = A + 5A 110 = 5A A = 110/5 A = 22 If A = 22 Then, 3A = 3(22) = 66 Therefore, the VALUE of 3A is 66. |

एक चतुर्भुज ABCD का क्षेत्रफल ज्ञात कीजिए, जिसमें[tex]AB = 3cm , BC = 4cm ,CD = 4cm , DA = 5cm[/tex] और है। |
|
Answer» Answer: चतुर्भुज ABCD का क्षेत्रफल 15.2 सेमी² है।Step-by-step explanation: ΔABC में, AC² = AB² + BC² [पाइथागोरस प्रमेय से] 5² = 3² + 4² 25 = 25 अतः ΔABC समकोण त्रिभुज ,जिसमें ∠B = 90º है।
ΔABC का क्षेत्रफल = 1/2 आधार × ऊंचाई = ½ × AB × BC = ½ × 3 × 4 = 6 सेमी² समकोण ΔABC का क्षेत्रफल = 6 सेमी² ……..(1)
ΔACD में, दिया है : AC (a) = 5 सेमी , CD (b) = 4 सेमी , DA (c) = 5 सेमी त्रिभुज का अर्द्ध परिमाप, s = (a + b + c)/2 s = (5 + 5 + 4)/2 s = 14/2 s = 7 सेमी
हीरोन के सूत्र से, ΔACD का क्षेत्रफल , A = √[s (s - a) (s - b) (s - c)]A = √7(7 – 5) (7 – 5) (7 – 4) A = √7 × 2 × 2 × 3 A = 2√21 सेमी² [√21 = 4.6] A = 2 × 4.6 A = 9.2 सेमी² (लगभग) ……………….(2)
चतुर्भुज ABCD का क्षेत्रफल = समकोण ΔABC का क्षेत्रफल + ΔACD का क्षेत्रफल = 6 + 9.2 [समी (1) तथा (2) से] चतुर्भुज ABCD का क्षेत्रफल = 15.2 सेमी² अतः , चतुर्भुज ABCD का क्षेत्रफल 15.2 सेमी² है।आशा है कि यह उत्तर आपकी मदद करेगा। इस पाठ से संबंधित कुछ और प्रश्न : एक पार्क चतुर्भुज ABCD के आकार का है, जिसमें

|
Answer» Answer: 25 days Step-by-step explanation: a=b+C, a+b=10, c=50, b=? work done by a and b in 1 day=1/10 work done by c alone in 1 day=1/50 total work done by a,b,c in 1 day=(1/10)+(1/50)=(6/50)=(3/25) work done by a in 1 day = work done by b and c in 1 day = x therefore, x+x=(3/25) 2X=(3/25) x=(3/50) work done by b and c in 1 day = (3/50) work done by b alone in 1 day =(3/50)-(1/50)=(2/50)=(1/25) B alone can work in 25 days. |
