A girl of height 90cm is walking away from the base of a lamppost at a speed of 1.2m/s. If the lamp is 3.6 m above the ground, find the length of her shadow after 4 seconds. |
|
Answer» B Represent the lamp Post of height 3. 6m ⚫ The Girls Walk at a speed of 1. 2 m/s ⏩ In 4 Seconds She walks 4 × 1. 2 m = 4. 8 m And reaches D. ⏩ LET CD represent the girl of height 0.9 m and DE is her shadow of X METRE. Now, in ∆CDE and ∆ ABE ∆CDE = ∆ ABE... Each 90°E. = E Common=> ∆ CDE - ∆ ABE AA Similarity Criterion. => DE/BE = CD/AB ⏩ X/X+4. 8 = 0. 9/3. 6 ⚫ 4x = x + 4. 8 4x-x = 4. 8 3X. = 4. 8 X = 4. 8/3⏩ X. = 1. 6 m. So, length of the shadow after 4 seconds = 1. 6 m. |

A pit is 10 m long and 2 m wide is filled with 4.8 m cubed of sand. What is the depth of the pit |
|
Answer» 24 CM or 0.24 mStep-by-step explanation:LET the HEIGHT of pit be 'x'Assuming the pit to be cuboidal, we get that:VOLUME of Sand present = Volume of PitVolume of Pit = LENGTH × Breadth × Height⇒ 4.8 m³ = 10 m × 2 m × x⇒ 4.8 m³ = 20 m² × x⇒ x = 4.8 m³ / 20 m²⇒ x = 0.24 m or 24 cmHence the height is 24 cm.Thanks !! |

Two different rectangles having same perimeter then their areas are? |
|
Answer» -step explanation:ASSUME a square of SIDE s and rectangle with one side as a and b. Since, the perimeters are equal 4s = 2(a+b) b = 2s-a. The sides of rectangle can be rewritten as a and 2s-a. Areas are s² and (2s-a)a If they are equal :- s² = 2sa - a² s² -2sa + a² = 0 (s-a)² = 0 s=a So, only when s = a, both perimeter and AREA are equal. |

Find a quadratic polynomial each with the given numbers as the sum and product of its zeroes respectively. (i) 1/4,-1 |
|
Answer» 4x² - X - 4Step-by-step explanation:Sum of ZEROES = ¼Product of zeroes = -1Quadratic polynomial is of the form, => x² - x(sum of zeroes) + (PRODUCT of zeroes) = x² - x(¼) - 1= x² - x/4 - 1Multiply the above equation by 4,= 4(x² - x/4 - 1)= 4x² - x - 4Hope it helps |

What is the ratio of the area of the semicircle to the quarter circle . |
| Answer» REQUIRED ratio of semi - circle to quarter circle is 2 / 3.Step-by-step explanation:In the FIGURE, a square is there whose length is equal to the length of radius of the semi - circle. Let the radius of semi circle is a, and, diameter or AC is 2a.Also, let that the length of radius of quarter circle is r, In TRIANGLE ABC, length of AB and BC is equal to the length of radius of quarter circle or r, and length of AC is 2a( from above ).In triangle AOB and triangle COB, AO = OC ( radius of semi circle )AB = BC ( radius of quarter circle )OB = OB ( common )Hence triangle AOB is congruent to triangle COB. Thus, angle AOB or angle COB is 90*.Therefore, by Pythagoras theorem, = > AB^2 = AO^2 + OB^2= > r^2 = a^2 + OB^2= > r^2 - a^2 = OB^2 …( i )From the properties of square we know that the area formed by joining the two tangents ( also , radius ) is a square. Thus, by Pythagoras theorem,= > side^2 + side^2 = OB^2= > a^2 + a^2 = OB^2 ...( ii )Comparing the values of OB^2 from ( i ) and ( ii ),= > √{ r^2 - a^2 } = a√2= > r^2 - a^2 = 2a^2= > r^2 = 2a^2 + a^2= > r^2 = 3a^2= > 1 / 3 = a^2 / r^2= > 2 / 3 = (2 π a^2 ) / ( π r^2 )= > 2 / 3 = ( π a^2 ) / ( π r^2 / 2 )= > 2 / 3 = ( π a^2 / 2 ) / { π r^2 / ( 2 x 2 ) } = > 2 / 3 = ( π a^2 / 2 ) / ( π r^2 / 4 )= > 2 / 3 = Area of semi - circle / area of quarter circleHence the required ratio of semi - circle to quarter circle is 2 / 3. | |

What is NAV of a unit , if Rs.4725 has to be invested to purchase 300 units of a mutual fund? |
|
Answer» Net asset VALUE (NAV) is the price at which you buy the unit of a scheme, it is the value of a mutual fund scheme's assets minus the value of its liabilities per unit. for example , if you invest 10,000 Rs in a scheme with NAV of Rs. 200, you will RECEIVE (10000/200) = 50units Step-by-step explanation:The mathematical formula for calculating NAV is:Net Asset Value (NAV) = (Assets – Debts) / (Number of Outstanding units)In simple WORDS, NAV is the price which you PAY to buy a unit of mutual fund scheme when you invest. You also sell it on NAV, but the sell price can be lower than NAV if there is an exit load. Exit load is always CHARGEABLE as a percentage of the NAV. |

Answer» Step-by-step explanation:A trapezoid is not EVEN a parallelogram as you don't have two pairs of PARALLEL sides in the quadrilateral. A RECTANGLE is a parallelogram which also has RIGHT angles,NO. A trapezoid is defined (in North America) to be a quadrilateral that has exactly one pair of parallel sides. (This object is called a trapezium in British English.) A quadrilateral with two pairs of parallel sides is called a parallelogram; a parallelogram with right angles is a rectangle.-google |
