Answer:

Number of  jars can be filled from 15kg of the salt = 468 or 469 jars (Approx.)

Step-by-step explanation:

Given:

Amount of salt containing in jar = 32 gram

Total amount of salt in jar = 15 kg

Find:

Number of  jars can be filled from 15kg of the salt

Computation:

Total amount of salt in jar = 15 kg

Total amount of salt in jar (in grams) = 15 x 1000 g

Total amount of salt in jar (in grams) = 15,000 g

Number of  jars can be filled from 15kg of the salt = Total amount of salt in jar (in grams) / Amount of salt containing in jar

Number of  jars can be filled from 15kg of the salt = 15,000 / 32

Number of  jars can be filled from 15kg of the salt = 468.75

Number of  jars can be filled from 15kg of the salt = 468 or 469 jars (Approx.)

One of the roots of the quadratic equation x2−5mx+6m2=0 is 36. Find the greatest possible value of the second root. Help needed
Ivenika [448]
<h2>The greatest possible value of the second root, β = 54 </h2>

Step-by-step explanation:

The given quadratic equation:

x^2-5mx+6m^2=0

Let α and β be the roots of the given quadratic equation.

α = 36

To find,  the greatest possible value of the second root ( β) = ?

∴ The sum of the roots,

α + β = \dfrac{-b}{a}

⇒ 36 + β = \dfrac{-(-5m)}{1}

⇒ 5m = 36 + β               ............. (1)

The product of the roots,

α.β = \dfrac{c}{a}

⇒ 36.\beta=\dfrac{6m^2}{1}

⇒ 6.\beta=m^2                   ............. (2)        

From equations (1) and (2), we get  

⇒ (\dfrac{36+\beta}{5})^{2}=6\beta

⇒ \beta^2-78\beta+1296=0

⇒ \beta^2-54B\beta-24B\beta+1296=0

⇒ β(β - 54) - 24(β - 54) = 0

⇒ (β - 54)(β - 24) = 0

⇒ β - 54 = 0 or, β - 24 = 0

⇒ β = 54 or, β = 24

∴  The greatest possible value of the second root, β = 54

What are the answers??
Anettt [7]
2x + 5x + 4 = 25
7x + 4 = 25
7x +4 (-4) = 25 (-4)
7x = 21
7x/7 = 21/7
x = 3

26 = 3b - 2 - 7b
26 = 4b - 2
26 + 2 = 4b - 2 (+2)
28/4 = 4b/4
b = 7

5m/8 - 6/8 +3m/8 = 2/8
8m/8 = 8/8
m = 1
