Answer:

$12 \: cm$

Step-by-step explanation:

$Given, volume \: of \: cube = 1728 {cm}^{3}$

$Let \: x \: be \: the \: side \: of \: the \: cube.$

$Volume \: of \: the \: cube = {x}^{3}$

${x}^{3} = 1728 {cm}^{3}$

$x = \sqrt[3]{1728}$

$x = 12 \: cm$

Which point on the unit circle corresponds to -pi/6 ?

xeze [42]

Answer:

(srt(3)/2, -1/2)

Step-by-step explanation:

x = rcos theta

r = 1 on unit circle

x = 1 cos (-pi/6)

x = sqrt(3)/2

y = r sin theta

y =1 sin (-pi/6)=

y = -1/2

Solve the quadratic equation by completing the square x^2+5x-3=0

PIT_PIT [208]

${\tt{x = \frac{ -b± \sqrt{ {b}^{2} - 4ac } }{2a} }}$

${\tt{ x = \frac{ - 5±\sqrt{{5}^{2} - 4 \times 1 \times ( - 3)} }{2 \times 1} }}$

${\tt{x = \frac{ - 5±\sqrt{25 + 12} }{2} }}$

${\tt{x = \frac{ - 5 ±\sqrt{37} }{2} }}$

$\: \:$

${\tt{x = \frac{ - 5 + \sqrt{37} }{2} }}$

${\tt{x = \frac{ - 5 - \sqrt{37} }{2} }}$

Nataliya [291]

With the help of the ratio method, we conclude that 72 grams of sugar should be added.

<h3>What is Ratio Method?</h3>

In the ratio method, we compare two quantities by equating their two ratios; this equation is also referred to as a proportion.
The cross-multiplication method will be used to solve it.

So, 'n=5' will be the number of rings.

'w = 18 grams' will be the weight of each ring.
Total weight: w₀ = n × w = 5 × 18 = 90 grams

Let 's' be silver. Then,

New weight: wₙ = s + 90
Old % of gold: p₀ = 90% = 0.9
New % of gold: pₙ = 50% = 0.5

Now, use the ratio method as follows:

$\frac{w_o}{w_n}=\frac{p_n}{p_o}$
$\frac{90}{s+90}=\frac{0.5}{0.9}$
90 × 0.9 = 0.5 × (s + 90)
81 = 0.5s + 0.5 × 90
81 = 0.5s + 45
81 - 45 = 0.5s
36 = 0.5s
36/0.5 = s
72 = s
So, s = 72

Therefore, with the help of the ratio method, we conclude that 72 grams of sugar should be added.

The correct question is given below:
A jeweler has five rings, each weighing 18 grams, made of alloys of 10% silver and 90% gold. He decides to melt down the rings and add enough silver to reduce the gold content to 50%. How much silver should he add?
