Solve the equation p^2 + 4p = 1 by completing the square.
igor_vitrenko [27]

Answer:

p = -2 ±sqrt( 5)

Step-by-step explanation:

p^2 + 4p = 1

Take the coefficient of p

4

Divide by 2

4/2 =2

Square it

2^2 = 4

Add it to each side

p^2 + 4p+4 = 1+4

(p+2) ^2 = 5

Take the square root of each side

sqrt((p+2) ^2) =±sqrt( 5)

p+2 = ±sqrt( 5)

Subtract 2 from each side

p+2-2 = -2 ±sqrt( 5)

p = -2 ±sqrt( 5)

A model of a submarine has a length of 6.6 meters. Use the scale 1:35 to find the length
kirill115 [55]
The scale 1:35 indicates that for every 1 meter on the scale model, there are really 35 meters in real life.

So if the scale model is 6.6 meters, you would do 35 * 6.6 to find the length in real life, which is 231 meters.

The answer is 231 meters.

joe has a ring weighing 14 grams made of an alloy of 14 % silver and the rest gold. he decides to melt down the rings and add en
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?
