Question

The melting point of aluminum is 1220 degrees Fahrenheit. This is 1.96 times the melting point of lead. What is the melting point of lead?

Answer 1

Answer:

The melting point of led is: 622.45 Fahrenheit

Step-by-step explanation:

Given that

The melting point of aluminum is 1220 degrees Fahrenheit.

Let a be the melting point of aluminum and l be the melting point of lead.

The according to given statement, we can write that

$a = 1.96l$

Putting the value of a

$1220=1.96l$

dividing both sides by 1.96

$\frac{1220}{1.96} = \frac{1.96l}{1.96}\\l = 622.4489...$

Rounding off to nearest hundredth

$l = 622.45$

Hence,

The melting point of led is: 622.45 Fahrenheit
