Step-by-step explanation:
The order of the top three are
- Silver
- Copper
- Gold
In that order. Copper is used where there is some tolerance for corrosion for it much cheaper than the other two. Gold is used where corosion is a consideration because Gold does not tarnish. Silver is used when conductivity is the primary concern.

Answer:
Pure silver is best conductor of electricity.
Step-by-step explanation:
Conductivity is the property of materials to which extent a material allows electric current to flow through it.
Metals is defined as the substance which is good conductor of heat and electricity.
Given are list of highly conductive metals,
Pure silver
Pure copper
Pure gold
Aluminium
The presence of free electrons determines a metal’s conductivity.
Silver and copper are metals with single, free-moving electrons.
Pure silver is the most conductive metal of all metals

Answer:
(A) Linear pair postulate
Step-by-step explanation:
Given: AB intersects DE at point C.
To prove: ∠DCB≅∠ECA
Proof:
Statements Reasons
1. AB intersects DE at point C. given
2. ∠DCB and ∠BCE are a linear pair Definition of linear pair
3. ∠DCB is supplementary to ∠BCE Linear pair postulate
4. ∠BCE and ∠ECA are a linear pair Definition of linear pair
5. ∠BCE is supplementary to ∠ECA Linear pair postulate
Thus, from statement 2 and 5, we have
∠DCB+∠BCE=180° and ∠BCE+∠ECA=180°
⇒∠DCB+∠BCE=∠BCE+∠ECA
⇒∠DCB≅∠ECA
Hence proved
thus, option A is correct.

We have then:
19/50 = 0.38
13/20 = 0.65
Then, to know the percentage, we must multiply this value by 100.
0.38 * 100 = 38%
0.65 * 100 = 65%
answer
the equivalent percent for each fraction are
38%
65%
respectively

Answer:
If my math is correct, the answer is about 57.14 grams
Step-by-step explanation:
The fact that one kilogram is about 35 ounces is a conversion factor, so if you use that in the equation, it goes something like this
2 ounces /1 x 1 kg/35 ounces x 1000g/1kg
To make the equation balance out, you need to end in grams, which is what the question asks. To get ounces to cancel, you need to use the conversion factor, 35 ounces on the bottom (since ounces over ounces cancels), then you have kilograms left, which you need to convert to grams. You can do this by using the metric system line, which goes Kilo, Hecta, Deca, The unit, Deci, Centi, and milli, each unit increasing by ten as it goes along. Thus, one kilogram equals 1000 grams. Combining this all together, you get 57.14 grams.
Hope this helps!

Step-by-step explanation:
If you find two numbers that multiply to 24, you have three sets of numbers, but 6 and 4 are the only numbers that are two centimeters apart
Final answer:
The question is about finding the length of a rectangle. By creating and solving a quadratic equation with provided information, the width and length of the rectangle are 4 cm and 6 cm respectively.
Explanation:
The problem involves finding the length of a rectangle. To solve this, we need to consider the fact that we know information about the dimensions and area of the rectangle. The area of a rectangle is obtained by performing the multiplication of the length and the width. In this specific problem, it's stated that the length is 2 cm more than the width, and we also know that the area of the rectangle is 24 cm2.
Let's represent the width by x. Therefore, the length would be x+2. Since the area is the length multiplied by the width, we create the equation x*(x+2) = 24, which simplifies to x2+2x=24. Subtracting 24 from both sides, we get x2+2x-24 = 0.
This a quadratic equation and we'll solve for x using the quadratic formula, which results in x = 4 or x = -6. Since the width cannot be negative, x = 4 cm. After this, substitute the width (x) into the length equation. The length (x + 2) is 4 cm + 2 cm = 6 cm.
