If each edge of a cube in doubled. (a) how mony times will its surface area increase ?(b) how many times will its volume increase ? |
|
Answer» Answer: a) Four times b) Eight times Step-by-step explanation: Given-----> Each edge of CUBE is DOUBLED To find-----> a) How many times wii its surface area INCREASE b) how many times will its volume increase Solution-----> Let initially edge of cube be x Surface area of cube ( S₁ ) = 6 ( edge )² S₁ = 6 ( x )² S₁ = 6 x² Volume of cube ( V₁ ) = edge³ V₁ = x³ Now , edge of cube is doubled so, Edge of new cube = 2x Now , surface area of new cube ( S₂ ) = 6 ( new edge )² S₂ = 6 ( 2x )² = 6 ( 4x² ) S₂ = 24 x² Volume of new cube = ( New edge )³ V₂ = ( 2x )³ V₂ = 8x³ a) S₂ = 24x² = 4 ( 6x² ) S₂ = 4 ( S₁ ) It MEANS surface area increase four times . b) V₂ = 8x³ V₂ = 8 ( V₁ ) It means volume is increased eight times . |

the volume and curved surface area of a cylinder are 1650 cm cube and 60 CM square respectively find radius and height of the cylinder |
|
Answer» Answer: It is given that VOLUME of a cylinder = 1650cm. pir^2h = 1650 ---- (1) It is given that CURVED surface area of cylinder = 660cm. 2pirh = 660cm. ----- (2) On solving (1) and (2) we get R/2 = 1650/660 r = 1650/330 r = 5cm. Substitute r = 5 in (2), we get 2pirh = 660 2 * 22/7 * 5 * h = 660 2 * 22 * 5 * h = 660 * 7 220 * h = 4620 h = 4620/220 h = 21cm Therefore the radius of the cylinder = 5cm. the height of the cylinder = 21cm.

Factorise the above equation:(The answer must be : (ax+by)(a+1-ax-by) |
Answer» Step-by-step EXPLANATION:Given : ax + a²x + ABY + by - (ax + by)² Rearranging the terms, we get → ax + by + a²x + aby - (ax + by)² → (ax + by) + a²x + aby - (ax + by)² TAKING COMMON terms out from a²x + aby, we get → (ax + by) + a(ax + by) - (ax + by)² Now, taking out (ax + by) as common, we get → (ax + by) [1 + a - (ax + by)] On further solving, we get → (ax + by)(1 + a - ax - by) |

Proof that LOG 96+ 5 LOG 2=LOG3 |
|
Answer» hey dear, assuming that your question should ACTUALLY be Log 96= 5 log 2 + log 3... here's your proof... we know that LCM of 96 = 2^5 x 3 and USING log identity logb x + logb y = logb(xy) ... we have log 96 = log 2^5 + log 3 i,e.... log (2^5 x 3) = log 2^5 + log 3 (or) Log 96= 5 log 2 log 3... ∴ it has been proved that Log 96= 5 log 2+ log 3... |

farhan order one plate of seafood from restaurant which offers discount of 25%and mark up price of food is $9.50 there is service charges of 10%,and Gst is 7%,how much he paid |
|
Answer» Answer: Answer: The TOTAL AMOUNT of money he has to pay for the dish is $8.3861. Step-by-step explanation: Here, the marked PRICE of the seafood fried rice = $9.50 Now, discount on the marked price = 25% CALCULATING 25% of $9.50 = So, the discount offered = $2.375 Now, the Selling Price of dish = Marked Price - Discount = $9.50 - $2.375 = $7.125 Now, here the service charge applied here = 10% Calculating 10% of $7.125 = So, the service charge applied = $0.7125 So, the new Selling Price of dish = Selling Price + Service Charge = $7.125 + $0.7125 = $7.8375 Again, here the GST applied here = 7% Calculating 7% of $7.8375 = So, the GST applied = $0.5486 So, the new Selling Price of dish = Selling Price + GST = $7.8375 + $0.5486 = $8.3861 Hence, the total amount of money he has to pay for the dish is $8.3861.

Answer» Answer: a2 + b2 = C2 PROOF of Pythagoras Theorem Given: A ∆ XYZ in which ∠XYZ = 90°. To prove: XZ² = XY² + YZ² Construction: Draw YO ⊥ XZ Proof: In ∆XOY and ∆XYZ, we have, ∠X = ∠X → common ∠XOY = ∠XYZ → each equal to 90° Therefore, ∆ XOY ~ ∆ XYZ → by AA-similarity ⇒ XO/XY = XY/XZ ⇒ XO × XZ = XY²----------------- (i) In ∆YOZ and ∆XYZ, we have, ∠Z = ∠Z → common ∠YOZ = ∠XYZ → each equal to 90° Therefore, ∆ YOZ ~ ∆ XYZ → by AA-similarity ⇒ OZ/YZ = YZ/XZ ⇒ OZ × XZ = YZ² ----------------- (ii) From (i) and (ii) we GET, XO × XZ + OZ × XZ = (XY² + YZ²) ⇒ (XO + OZ) × XZ = (XY² + YZ²) ⇒ XZ × XZ = (XY² + YZ²) ⇒ XZ² = (XY² + YZ²) |

|
Answer» Answer: Answer: number of shares sold by him is 40 Step-by-step explanation: Let number of shares sold be s Nominal value = 100 Rate of DIVIDEND = 10% Hence Annual income(A) = Rate of dividend x nominal value x number of shares => A = 10/100 x 100 x s = 10s.....................eq1 As each share is sold at a discount of 25% selling price of ONE share = RS 75 selling price of s number of shares = Rs 75s Given that nominal value = 100 Market value = 80 rate of dividend = 16 % Number of shares bought = selling price of OLD shares/market value = 75s/80 Hence new annual income (B) B = Rate of dividend x nominal value x number of shares => B = 16/100 x 100 x 75s/80 => B = 15s Given that his annual income increases by Rs 200 => 15s - 10s = 200 => 5s = 200 => s = 40 Hence number of shares sold by him is 40 Plz mark brainliest ❤️❤️ |
