David cuts a bread into two equal pieces and cuts one half into smaller pieces of equal size. Each of the small pieces is twenty grams in weight. If he has seven pieces of the bread all with him, how heavy is the original cake? |
|
Answer» Answer: 240 gm. If she has 7 PIECES TOTALLY, it means that one of those pieces is the uncut half, and the other half is CUT into 6 pieces. Each of those 6 pieces has a weight of 20 gm which totally weighs 6*20= 120gm. If one half is 120 gm, then so is the other. |

2. Joseph jogs from one end A to the other end B of a strug300 m road in 2 minutes 30 seconds and then turns arounand jogs 100 m back to point in another 1 minute WhatanJoseph's average speeds and velocities in jogging (a) from AB and (b) from A to C? |
|
Answer» Step-by-step explanation: Velocity = dispacement / time Speed = DISTANCE / time a) when he jogs from A to B on a straight road, DISPLACEMENT = distance = 300m time = 2 MINUTES 30 seconds = 150 s velocity = 300/150 = 2 m/s speed = 300/150 = 2m/s b)when he jogs from A to B and turns back to C, displacement = 300-100 = 200m distance = 300+100 = 400m time = 3 minute 30 second = 210 s velocity = 200/210 = 20/21 m/s speed = 400/210 = 40/21 m/s |

if x: yis the duplicate ratio of a:b, a nd a:b is the sub-duplicate ratio of a+x:a-y, then the ratios 3x:a and x-y:y will be equal |
|
Answer» Answer:Since x : y is duplicate ratio of (x + z) and ( y + z) ∴ x : y = (x + z)2 : (y + z)2 x(y + z)2 = y (x + z)2 On simplifying we get xy2 + xz2 = yx2 + yz2 ⇒ X2Y – xy2 = xz2 – yz2 ⇒ xy(x – y) = z2(x – y) ⇒ xy = z2 (x ≠ y) ⇒ x : z : : z : y Hence proved. |

The parallel sides of a trapezium are 40 cm and 70 cm. If the non-parallelsides are equal, each being 25 cm, find the area of the trapezium. |
|
Answer» ANSWER:Area of Trapezium is 1100 sq.cm. Step-by-step explanation: We have DRAWN the DIAGRAM for your reference. Given: The parallel sides of trapezium are 40 cm and 70 cm. hence ACCORDING to diagram: AD = 40 cm BC = 70 cm Also Given: Its non parallel sides are equal 25 cm each. AB = 25 cm CD =25 cm So first we will draw imaginary lines AE and DF which are perpendicular BC such that; EF = AD = 40 cm so, BE = FC = 15 cm each Now In triangle Δ AEB. m∠E = 90° Hence By Pythagoras theorem we get; Substituting the values we get; Now Taking Square root on both side we get; Now we need to find the Area of trapezium. Area of trapezium is equal to half times sum of parallel side times distance between them. framing in equation form we get; Area of trapezium = Hence Area of Trapezium is 1100 sq.cm.

14. Find the smallest number by which 2925 must be difind the square root of the perfect square so obtained.15. 1225 plants are to be planted in a garden in such a way that each row contains asmany plants as the number of rows. Find the number of rows and the number of plants in |
|
Answer» 1. First, we NEED to do prime factorization of 2925. 2925 ⇒ ∴ 13 doesn't have a PAIR. So 13 is the smallest number that can be divided by 2925 to get a perfect square. Now lets prime factorize 225 to get the square root. 225 ⇒ Now we need to TAKE one number from each pair to find the square root. ∴So the square root of the perfect square is ⇒ 2. Number of plants ⇒ 1225 Number of plants in each row ⇒ To find 1225 ⇒ Now we need to take one number from each pair to find the square root. ∴ 35 plants will be in each row. |
