5. A bar of metal contains 20% silver and another bar contains 12% silver. A jeweller wants toValue Based make a mixed metal using these two types of metal bars, How many grams ofQuestion cach metal bar should he use to make a 40 g bar containing 14 % silver? Whatvalues are represented by the jeweller?​

Answer»

Answer:

10 & 30 gm

Step-by-step explanation:

A bar of metal CONTAINS 20% silver and ANOTHER bar contains 12% silver. A JEWELLER wants to  Value Based make a mixed metal using these two types of metal bars, How many grams of  Question Each metal bar should he use to make a 40 g bar containing 14 % silver

A Bar  Contains  Silver = 20%  & non Silver = 100-20 = 80 %

Another Bar Contains Silver = 12%  & non-Silver = 100-20 = 88%

Let Say X gm of A bar is taken and 40 - X gm of another bar is taken

then total Silver = (20/100)X + (12/100)(40-X)

= (1/100)( 20X + 480 - 12X)

= (480 + 8X)/100  gm

14 % of 40 g  = (14/100) * 40  =  5.6 g

(480 + 8X)/100 = 5.6

=> 480 + 8X = 560

=> 8X = 80

=> X = 10 gm

A bar = 10 gm

Another Bar = 30 gm

1. Three numbers are in the ratio 2 : 3:4. The sum oftheir cubes is 72171. Find the numbers.​

Answer»

Step-by-step explanation:

Let the numbers be 2x, 3X and 4X

then

(2x) ^3 + (3x) ^3 + (4x) ^3 = 72171

8x^3 + 27x^3 + 64x^3 = 72171

take x^3 common

then

x^3(8 + 27 + 64) = 72171

x^3(99) = 72171

x^3 = 72171/99

x^3 = 729

x = ³√729

x = 9

Numbers are

2x = 2 * 9 = 18

3x = 3 * 9 = 27

4x = 4 * 9 = 36

Hope it will be HELPFUL

√3x sq. − 2√2x− 2√3 = 0 Spitting the middle term​

Answer»

\huge \mathfrak  \green {|hello \: buddy|  } \\  \small \red {your \: answer}

√3 x² - 2√2 X - 2√3 = 0

Multiplying √3 and 2√3 = 6

now, SPLIT this in such a way that it's sum of DIFFERENCE will be -2√2

i.e. -3√2 +√2 = -2√2

√3 x²-3√2x +√2x -2√3 =0

=√3x(x -√6) +√2(x -√6) =0

=(x-√6)(√3x +√2) =0

So, (x-√6)=0 or (√3x +√2) =0

x = √6 or x= -√(2/3)= -√6/3

Find the zeros of the polynomial 2 x square - 3 x minus 2​

Answer»

p(x)= 2x²-3x-2

To Find : The zeroes of the above polynomial.

Solution :

2x²-3x-2 = 0

The classification of POLYNOMIALS can be DONE in two ways :

• On the basis of degree :

★ Linear Polynomial - The polynomial having the degree = 1

★ Quadratic Polynomial - The polynomial having the degree = 2

★ Cubic Polynomial - The polynomial having the degree = 3

• On the basis of terms :

★Monomial : The polynomial having a single term only.

★ Binomial : The polynomial having two terms.

★ Trinomial : The polynomial having 3 terms.
