If the cost of the cardboard is Rs. 4 for 1000 cm2, find the cost of cardboard required for supplying 300 boxes of each kind.
Answer» Given:- The bigger of dimensions 25 cm× 20 cm× 5 cm and the smaller dimensions 15 cm× 12 cm×5cm. all the overlaps, 5% of TOTAL surface area is REQUIRED extra. the cost of cardboard is rs 4 for 1000 cm square. To FIND:- Find the cost of cardboard required for supplying 250 boxes of each kind. Solutions:- Length of bigger box = 25cm Breadth of bigger box = 20cm Height of bigger box = 5cm Total surface area bigger box = 2(lb + bh + hl) = 2(25 × 20 + 20 × 5 + 5 × 25) = 2(500 + 100 + 125) = 2 × 725 = 1450cm² Extra area required for overlapping = 1450 × 5 / 100 = 1450/20 = 72.5cm² While considering all overlaps total of 1 bigger box. = 1450 + 72.5 = 1522.5cm² Area of cardboard sheet required for 250 such bigger boxes. = 1522.5 × 250 = 380625cm² Total surface area of smaller box. = 2(15 × 12 + 15 × 5 + 12 × 5) = 2(180 + 75 + 60) = 2 × 315 = 630 Therefore, Extre area of required for overlapping. = 630 × 5 / 100 = 63/2 = 31.5cm² Total surface area of 1 smaller box while considering all overlaps. = 630 + 31.5 = 661.5cm² Area of cardboard sheet required for 250 smaller boxes. = 250 × 661.5 = 165375cm² Total cardboard sheet required = 380632 + 165375 = 546000cm² Cost of 1000cm² cardboard sheet = Rs 4. Cast of 546000cm² cardboard sheet. = Rs (546000/1000 × 4) = Rs 546 × 4 = Rs 2184 Hence, the cost of cardboard sheet required for 250 such boxes of each will be Rs 2184.

Shanti Sweets Stall was placing an order for making cardboard boxes for packing their sweets. Two sizes of boxes were required. The bigger of dimensions 25 cm × 20 cm × 5 cm and the smaller of dimensions 15 cm × 12 cm × 5 cm. For all the overlaps, 5% of the total surface area is required extra. If the cost of the cardboard is Rs. 4 for 1000 cm2, find the cost of cardboard required for supplying 300 boxes of each kind.

Answer»

Given:-

The bigger of dimensions 25 cm× 20 cm× 5 cm and the smaller dimensions 15 cm× 12 cm×5cm.

all the overlaps, 5% of TOTAL surface area is REQUIRED extra.

the cost of cardboard is rs 4 for 1000 cm square.

To FIND:-

Find the cost of cardboard required for supplying 250 boxes of each kind.

Solutions:-

Length of bigger box = 25cm

Breadth of bigger box = 20cm

Height of bigger box = 5cm

Total surface area bigger box = 2(lb + bh + hl)

= 2(25 × 20 + 20 × 5 + 5 × 25)

= 2(500 + 100 + 125)

= 2 × 725

= 1450cm²

Extra area required for overlapping = 1450 × 5 / 100

= 1450/20

= 72.5cm²

While considering all overlaps total of 1 bigger box.

= 1450 + 72.5

= 1522.5cm²

Area of cardboard sheet required for 250 such bigger boxes.

= 1522.5 × 250

= 380625cm²

Total surface area of smaller box.

= 2(15 × 12 + 15 × 5 + 12 × 5)

= 2(180 + 75 + 60)

= 2 × 315

= 630

Therefore,

Extre area of required for overlapping.

= 630 × 5 / 100

= 63/2

= 31.5cm²

Total surface area of 1 smaller box while considering all overlaps.

= 630 + 31.5

= 661.5cm²

Area of cardboard sheet required for 250 smaller boxes.

= 250 × 661.5

= 165375cm²

Total cardboard sheet required = 380632 + 165375

= 546000cm²

Cost of 1000cm² cardboard sheet = Rs 4.

Cast of 546000cm² cardboard sheet.

= Rs (546000/1000 × 4)

= Rs 546 × 4

= Rs 2184

Hence, the cost of cardboard sheet required for 250 such boxes of each will be Rs 2184.

Answer» Step-by-step explanation: Human-induced climate change has contributed to changing patterns of extreme weather across the GLOBE, from longer and hotter heat waves to heavier rains. From a BROAD perspective, all weather EVENTS are now connected to climate change. While natural variability continues to play a key role in extreme weather, climate change has shifted the odds and changed the natural limits, making certain types of extreme weather more frequent and more intense. While our understanding of how climate change affects extreme weather is still developing, evidence SUGGESTS that extreme weather MAY be affected even more than anticipated. Extreme weather is on the rise, and the indications are that it will continue to increase, in both predictable and unpredictable ways.

Step-by-step explanation:

To find → Height of tower (AB)

Let AB =h m

In △ABC, by Trigonometry

)m

Since BCDE is a ||gm, so BC=DE and CD = BE

∴DE=(

h−40

h=3h−120

2h=120m

h=60m

Height of tower = 60 m.

To find → HORIZONTAL Distance from point of observation (BC)

BC=

Answer»

$\large\underline{\sf{Formula \: Used-}}$

$\bf \: \dfrac{d}{dx} <klux>X</klux> = 1$

$\bf \: \dfrac{d}{dx} {e}^{x} = {e}^{x}$

$\bf \: \dfrac{d}{dx} logx = \dfrac{1}{x}$

$\bf \: \dfrac{d}{dx} u.v = v \: \dfrac{d}{dx} u \: + \: u \: \dfrac{d}{dx} v$

$\bf \: {x}^{y} = {e}^{y \: logx}$

$\large\underline{\sf{Solution-}}$

$\rm :\longmapsto\: {x}^{y} + {y}^{x} = 12$

$\rm :\longmapsto\: {e}^{ylogx} + {e}^{xlogy} = 12$

On DIFFERENTIATING W. R. t. x, we GET

$\rm :\longmapsto\:\dfrac{d}{dx}( {e}^{ylogx} + {e}^{xlogy}) =\dfrac{d}{dx} 12$

$\rm :\longmapsto\: {e}^{ylogx} \dfrac{d}{dx} (ylogx) + {e}^{xlogy} \dfrac{d}{dx} (xlogy) = 0$

$\rm :\longmapsto\: {e}^{ylogx} (y\dfrac{d}{dx} logx + logx\dfrac{d}{dx} y) + {e}^{xlogy} (x\dfrac{d}{dx} logy + logy\dfrac{d}{dx} x) = 0$

$\rm :\longmapsto\: \sf \: {x}^{y} \bigg(\dfrac{y}{x} + logx\dfrac{dy}{dx} \bigg) + {y}^{x}\bigg(\dfrac{x}{y}\dfrac{dy}{dx} + logy \bigg) = 0$

$\rm :\longmapsto\: y{x}^{y - 1} + {x}^{y} logy\dfrac{dy}{dx} + {xy}^{x - 1} \dfrac{dy}{dx} + {y}^{x} logy = 0$

$\rm :\longmapsto\: {x}^{y} logy\dfrac{dy}{dx} + {xy}^{x - 1} \dfrac{dy}{dx} = - {y}^{x} logy - y{x}^{y - 1}$

$\rm :\longmapsto\: ({x}^{y} logy + {xy}^{x - 1}) \dfrac{dy}{dx} = - ( {y}^{x} logy + y{x}^{y - 1} )$

$\rm :\longmapsto\: \dfrac{dy}{dx} = \dfrac{ - ( {y}^{x} logy + y{x}^{y - 1} )}{ ({x}^{y} logy + {xy}^{x - 1})}$

$\rm :\longmapsto\: \dfrac{dy}{dx} = \dfrac{ - y( {y}^{x - 1} logy + {x}^{y - 1} )}{x ({x}^{y - 1} logy + {y}^{x - 1})}$
