Find the length ofthe zip(ii) A second zip is to be sewn along NK such thatNK is the perpendicular from N to OH. Calculatethe length of the second zip.
Answer» Answer: Part 1. OH. = 9.22 cm Part 2. NK = 5.86 cm Step-by-step explanation: we KNOW that A rectangle has OPPOSITE sides parallel and congruent and the measure of the internal angles is equal to 90 degrees each Part 1) Find the length of the zip OH In the right triangle OLH find out the length side of the hypotenuse OH Applying the Pythagoras Theorem OH sq = LH sq + LO sq We Have, LH = LM - HM LH = 9 - 2 = 7 cm LO = MN = 6 cm substitute the values OH sq = 7 sq + 6 sq OH sq = 85 OH = $\sqrt 85cm$ OH = 9.22 cm Part 2) Find the length of the zip NK we know that The measure of ANGLE LOH is equal to the measure of angle ONK, because triangle KON is a right triangle In the right triangle LOH find the cosine of angle LOH cos(∠LOH)=LO/OH -----> adjacent side to angle LOH divided by the hypotenuse substitute the values cos(∠LOH)=6/√85 -----> equation A In the right triangle KON find the cosine of angle ONK cos(∠ONK)=NK/ON -----> adjacent side to angle ONK divided by the hypotenuse substitute the values cos(∠ONK)=NK/9 -----> equation B Remember that cos(∠LOH)=cos(∠ONK) equate equation A and equation B $6/\sqrt85 = NK /9\\NK = 9(6/\sqrt85)\\NK = 5.86 cm$

The top surface of a pouch is in the shape of arectangle LMNO with sides 9 cm and 6 cm.(1) A zip is to be sewn along OH such that H is apoint on LM and HM = 2 cm. Find the length ofthe zip(ii) A second zip is to be sewn along NK such thatNK is the perpendicular from N to OH. Calculatethe length of the second zip.

Answer»

Answer:

Part 1. OH. = 9.22 cm

Part 2. NK = 5.86 cm

Step-by-step explanation:

we KNOW that

A rectangle has OPPOSITE sides parallel and congruent and the measure of the internal angles is equal to 90 degrees each

Part 1) Find the length of the zip OH

In the right triangle OLH find out the length side of the hypotenuse OH

Applying the Pythagoras Theorem

OH sq = LH sq + LO sq

We Have,

LH = LM - HM

LH = 9 - 2 = 7 cm

LO = MN = 6 cm

substitute the values

OH sq = 7 sq + 6 sq

OH sq = 85

OH = $\sqrt 85cm$

OH = 9.22 cm

Part 2) Find the length of the zip NK

we know that

The measure of ANGLE LOH is equal to the measure of angle ONK, because triangle KON is a right triangle

In the right triangle LOH find the cosine of angle LOH

cos(∠LOH)=LO/OH -----> adjacent side to angle LOH divided by the hypotenuse

substitute the values

cos(∠LOH)=6/√85 -----> equation A

In the right triangle KON find the cosine of angle ONK

cos(∠ONK)=NK/ON -----> adjacent side to angle ONK divided by the hypotenuse

substitute the values

cos(∠ONK)=NK/9 -----> equation B

Remember that

cos(∠LOH)=cos(∠ONK)

equate equation A and equation B

$6/\sqrt85 = NK /9\\NK = 9(6/\sqrt85)\\NK = 5.86 cm$

6.	What are the advantages of MCB
Answer» Answer: fuses. They immediately detect any abnormality and switch off the electrical circuit automatically. This prevents any permanent damage to electrical appliances and human beings. The MCB detects any excess CURRENT and breaks the circuit MCB Miniature Circuit Breakers (MCBs) are more advanced than fuses in that they are electromechanical DEVICES that prevent CIRCUITS from overcurrent. Modern MCBs such as that from HPL come with changeover switches that make them particularly good at securing the terminal connection. Unlike fuses, MCBs need not be replaced after a fault and therefore can be reused. MCBs are an improvement over fuses and remove any large operating costs. The main advantages that MCBs have over fuses are as follows: MCBs are more sensitive to current than fuses. They immediately detect any abnormality and switch off the electrical circuit automatically. This prevents any permanent damage to electrical appliances and human beings. The MCB detects any excess current and breaks the circuit. This is reflected in the tripping of the MCB. The fault in the electrical circuit can be identified easily if MCB switch is used. In this case, the Off position needs to be found. However, in a fuse, the entire wire needs to be checked. But this is not all! The fuse grip requires to be opened to identify the faulty zone making the work a little more tedious. Another advantage to using MCB is that the power supply can be resumed almost immediately. The techno MCB changeover switch needs to be pushed backed to the On position. In the case of a fuse, the WHOLE wire will have to be replaced first. Using and handling an MCB is much easier than using a fuse. This is because unlike the fuse, the user is not exposed to any live wires or parts. But replacing a fuse is a tedious process, one which exposes the person to live current. The best property of an MCB is that it can be used again and has minimal replacement and maintenance costs. This is not the case with fuses where the whole apparatus may require replacement when a fault is identified. HPL's changeover switches are an innovative design with TWO Pole and Four Pole versions and have a secure terminal connection.

11.	Find the perimeter of a triangle whose side are 6.3 cm , 5 cm and 4.7 cm
Answer» Step-by-step EXPLANATION: In chemistry, a SOLUTION is a special type of homogeneous mixture composed of two or more substances. In such a mixture, a SOLUTE is a substance dissolved in ANOTHER substance, known as a solvent. The mixing process of a solution happens at a scale where the effects of chemical polarity are involved, resulting in interactions that are specific to solvation. The solution usually has the state of the solvent when the solvent is the larger fraction of the mixture, as is commonly the case. One important PARAMETER of a solution is the concentration, which is a measure of the amount of solute in a given amount of solution or solvent. The term "aqueous solution" is used when one of the solvents is water.[1]

Define area of a plane closed figure. The length and breadth of a room are 6 meter and 5 meter respectively. How many square meters of carpet costs rupees 240 per square meter how much will it cost to cover the entire room

Answer»

Answer:

DEFINE AREA of a plane closed figure. The length and BREADTH of a room are 6 meter and 5 meter respectively. How many square meters of carpet costs rupees 240 per square meter how much will it cost to cover the entire room

Step-by-step EXPLANATION:

Length of the room = 13 m

Breadth of the room = 9 m

Area of the room = l × b = 13 × 9 = 117 sq m

Let the length of the carpet required = 'l' m

Width of the carpet = 75 cm = 0.75 m

Area of the carpet = Area of the room

⇒ l × 0.75 = 117

⇒ l = 117 / 0.75

⇒ l = 156 m

Length of the carpet required = 156 m

Cost of the carpet per metre = Rs 105

Total cost of the carpet = 156 × 105 = Rs 16380.

30.	the length and the breadth of a rectangular piece of land are 400m and 250m respectively. what is the cost of the land at ₹1000per square metre
Answer» The COST of the land at Rs. 1000 PER m² = Rs. 100000000. Given : The length of a rectangular piece = 400 m. The BREADTH of a rectangular piece = 250 m. To Find : The cost of the land at Rs. 1000 per m². Solution : We have to find the cost of the land at Rs. 1000 per m². So, for finding the cost of the land at Rs. 1000 per m². First we NEED to find the are of a rectangular piece. We know that, $\huge{ \blue{ \bf{ \star}}} \: \: \large \boxed{ \pink{ \bf{A = l \times b}}}$ Where, Area is denoted with A. Length is denoted with l. Breadth is denoted with b. We have, l = 400 m. b = 250 m. Now, substitute both the given values in the formula of the area of the rectangle. $\bf \implies 400 \: m \times 250 \: m \\ \\ \\ \bf \implies 100000 \: {m}^{2}$ Hence, the area of a rectangular park is 100000 m². Now, we can find the cost of the land at Rs. 1000 per m². Cost of 1 m² of land = Rs. 1000 Here we have to find the cost of 100000 m² of land. $\bf \implies Rs. \: 1000 \times 100000 \\ \\ \\ \bf \implies Rs. \: 100000000$ Hence, The cost of the land at Rs. 1000 per m² is Rs. 100000000.

the length and the breadth of a rectangular piece of land are 400m and 250m respectively. what is the cost of the land at ₹1000per square metre

Answer»

The COST of the land at Rs. 1000 PER m² = Rs. 100000000.

Given :

The length of a rectangular piece = 400 m.
The BREADTH of a rectangular piece = 250 m.

To Find :

The cost of the land at Rs. 1000 per m².

Solution :

We have to find the cost of the land at Rs. 1000 per m².

So, for finding the cost of the land at Rs. 1000 per m².

First we NEED to find the are of a rectangular piece.

We know that,

$\huge{ \blue{ \bf{ \star}}} \: \: \large \boxed{ \pink{ \bf{A = l \times b}}}$

Where,

Area is denoted with A.
Length is denoted with l.
Breadth is denoted with b.

We have,

l = 400 m.
b = 250 m.

Now, substitute both the given values in the formula of the area of the rectangle.

$\bf \implies 400 \: m \times 250 \: m \\ \\ \\ \bf \implies 100000 \: {m}^{2}$

Hence, the area of a rectangular park is 100000 m².

Now, we can find the cost of the land at Rs. 1000 per m².

Cost of 1 m² of land = Rs. 1000

Here we have to find the cost of 100000 m² of land.

$\bf \implies Rs. \: 1000 \times 100000 \\ \\ \\ \bf \implies Rs. \: 100000000$

Hence,

The cost of the land at Rs. 1000 per m² is Rs. 100000000.

Factorixe 6x²-9x-10..................

Answer»

Factorising 6x²-9x-10

The first term is, 6x² its coefficient is 6 .

The MIDDLE term is, -9x its coefficient is -9 .

The last term, "the constant", is -10

Step-1 : Multiply the coefficient of the first term by the constant 6 • -10 = -60

Step-2 : FIND TWO factors of -60 whose sum equals the coefficient of the middle term, which is -9 .

-60 + 1 = -59

-30 + 2 = -28

-20 + 3 = -17

-15 + 4 = -11

-12 + 5 = -7

-10 + 6 = -4

-6 + 10 = 4

-5 + 12 = 7

-4 + 15 = 11

-3 + 20 = 17

-2 + 30 = 28

-1 + 60 = 59

Observation : No two such factors can be found !!

35.

Find SP, when1: CP = 2360 Rs. and Profit = 8%. 2: CP = 380 Rs. and loss = 7.5%

Answer»

1. CP = 2360/-

PROFIT = 8%

SP = (100+GAIN)*CP/100

= (100+8)*2360/100

= 2548.8/-

2. CP = 380/-

LOSS = 7.5%

SP = (100-LOSS)*CP/100

Answer»

$\huge{\boxed{\boxed{\underline{\rm{\purple{<klux>ANSWER</klux>}}}}}}$

10x + 10y - 2z is the solution.

Step-by-step explanation:

We have to subtract the SUM of 9x - 5y + 4Z and 6x+2y+3Z from the sum of 10x -3y+4z and 3x+6y-5z.

(10x - 3y + 4z) + ( 3x + 6y - 5z) - (9x - 5y + 4z) + ( 6x + 2y + 3z)

10x + 3x - 9x + 6x = 10x [x terms]

-3y +6y + 5y + 2y = 10y [y terms]

4z - 5z - 4z +3z = -2z [z terms]
