Answer»

⟹ $\dfrac{\sqrt[4]{1250} }{ \sqrt[4]{2} }$

⟹ $\dfrac{ {(1250)}^{ \frac{1}{4} } }{ {(2)}^{ \frac{1}{4} } }$

⟹ ${ (\dfrac{1250}{2}) }^{ \frac{1}{4} }$

Now , 625×2 = 1250

⟹ ${ (625) }^{ \frac{1}{4} }$

we KNOW :- 625= 5×5×5×5 = 5⁴

⟹ ${ (5 \times 5 \times 5 \times 5) }^{ \frac{1}{4} }$

⟹ ${( {5}^{4} )}^{ \frac{1}{4} }$

⟹ ${( 5) }^{ \frac{1}{4} \times 4}$

⟹ $5$

Answer :- 5

18.	If the lab technician needs 30 liters of a 25% acid solution, how many liters of the 10% and the 30% acid solution should she mix to get what she needs?
Answer» ong>Answer: The answer is 7.5% of 10 LITER acid and 22.5 liters of 30% is required to make 30 liters of 25% acid. Step-by-step explanation: Let there be x liters of 10% acid solution and y liters of 30% acid solution. So, we can WRITE the equation as: x + y = 30 or y = 30 x x liters of 10% solution and y liters of 30% solution will add up to GIVE 30 liters of 25% acid solution. We can set up another equation as: x liters of 10% acid + y liters of 30% acid = 30 liters of 25% acid Changing percentage to decimals: 0.1(x) + 0.3(y) = 0.25(30) By PUTTING the values we get 0.1x + 0.3(30-x) = 7.5 0.1x + 9 -0.3x = 7.5 - 0.2x = - 1.5 x= 7.5 liters y = 30 - x = 30 - 7.5 = 22.5 liters Thus 7.5% of 10 liter acid and 22.5 liters of 30% is required to make 30 liters of 25% acid.

18.

If the lab technician needs 30 liters of a 25% acid solution, how many liters of the 10% and the 30% acid solution should she mix to get what she needs?

Answer»

ong>Answer:

The answer is 7.5% of 10 LITER acid and 22.5 liters of 30% is required to make 30 liters of 25% acid.

Step-by-step explanation:

Let there be x liters of 10% acid solution and y liters of 30% acid solution.

So, we can WRITE the equation as:

x + y = 30

or

y = 30 x

x liters of 10% solution and y liters of 30% solution will add up to GIVE 30 liters of 25% acid solution.

We can set up another equation as:

x liters of 10% acid + y liters of 30% acid = 30 liters of 25% acid

Changing percentage to decimals:

0.1(x) + 0.3(y) = 0.25(30)

By PUTTING the values we get

0.1x + 0.3(30-x) = 7.5

0.1x + 9 -0.3x = 7.5

- 0.2x = - 1.5

x= 7.5 liters

y = 30 - x = 30 - 7.5 = 22.5 liters

Thus 7.5% of 10 liter acid and 22.5 liters of 30% is required to make 30 liters of 25% acid.

23.

a planet has half the mass of 20% more than that of the earth and radius is 20% less than that of the earth then find the accleration due to gravity

Answer»

ong>Answer:

FORCE due to gravity at EARTH's surface on a mass m:

F = GMm/R2

F = Gravitational Force

G = Gravitational Constant

M = Earth's Mass

m = mass of body

R = Earth's radius

The acceleration is F/m:

g = F/m = GM/R2

For a planet with 0.9M and 1.2R:

a = G(0.9M)/(1.2R)2 = 0.625 (GM/R2) = 0.625g (62.5% of Earth's acceleration due to gravity)

The directions on the test are not very specific; however, they do say to give an exact solution. Stephanie is not sure if she should submit a decimal approximation or a simplified radical as the answer. 4x^3 = 756 1. What recommendation can you make to Stephanie regarding her answer to the cubic equation above? In your recommendation, explain what the term "exact" indicates with regards to the solution. 2. Solve the cubic equation from Stephanie’s test. Submit two solutions for the equation- a) your answer as a decimal approximation, rounded to the nearest hundredth, and b) as a simplified radical. Use substitution to check each version of your solution in the original equation. 3.

$\sf And, \: the \: units\: digit\: of \: the \: number \: be \: y$

$\sf The\: original \: number = 10x + y$

$\sf The\: number \: obtained \: by \: interchanging \: the \: digits = 10y + x$

$\bf\underline{\pink{Case\: 1:-}}$

The sum of the two digits number is 8.

$\sf \implies x + y = 8..…..(i)$

$\bf\underline{\orange{Case\: 2:-}}$

The number obtained by interchanging the digits exceeds original number by 18.

$\sf Reversed\: number - Original\: number = 18$

$\sf \implies 10y + x - (10x + y) = 18$

$\sf \implies 10y + x - 10x - y = 18$

$\sf \implies 9y - 9x = 18$

$\sf Divide\: the \: equation \: by \: 9$

$\sf \implies y - x = 2......(ii)$

$\underline{\sf Adding \: equations\: (i) \: and \: (ii)}$

$\sf \implies x + y + y - x = 2 + 8$

$\sf \implies 2y = 10$

$\sf \implies y = 5$

$\underline{\sf Substituting\: y = 5\: in \: equation\: (i)}$

$\sf \implies x + y = 8$

$\sf \implies x + 5 = 8$

$\sf \implies x = 8 - 5$

$\sf \implies x = 3$

$\sf The \: original \: number = 10x + y$

$\sf = 10(3) + 5$

$\sf = 30 + 5$

$\sf = 35$

Mother is 25 year older than her son.Find son's age if after 8 years ratio of son's age to mother's age will be 4:9

Answer»

$\boxed{\rm{\red{Solution \longrightarrow }}}$

Let present age of son be X years.

and mother be = (X+25) yrs.

After 8 years age of son= (X+8) yrs.

and mother's = (X+25+8) = (X+33) yrs.

Now ;

⇒ X+ 8 / X + 33 = 4/9

⇒ 9 ( X + 8 ) = 4 ( X + 33 )

⇒ 9X + 72 = 4X + 132

⇒ 9X - 4X = 132 - 72

⇒ 5X = 60

∴ X = 60/5

⇒∴ X = 12 yrs.

∴ Present age of son = X = 12 Years.

And mother = X + 25 = 12 + 25 = 37 years.
