Answer:
The answer s below
Step-by-step explanation:
a) The element is going to stay as a liquid if its temperature (t) is within the range: melting point ≤ t < boiling point.
Therefore the inequality for each element is given as:
For Gold:
1064 ≤ t < 2856
For Copper:
1085 ≤ t < 2562
For Iron:
1538 ≤ t < 2861
For lead:
327 ≤ t < 1749
and for Aluminium:
660 ≤ t < 2519
b) To get the element that would be liquid for the longest time, we need to calculate the difference between the melting and boiling points (i.e boiling point - melting point).
For Gold:
Difference = 2856 - 1064 = 1792°
For Copper:
Difference = 2562 - 1064 = 1498°
For Iron:
Difference = 2861 - 1538 = 1323°
For lead:
Difference = 1749 - 327 = 1422°
and for Aluminium:
Difference = 2519 - 660 = 1859°
Since Aluminium has the largest difference between the melting and boiling points, hence it will remain liquid for the longest amount of time.
c) The element with the smallest difference between the melting and boiling points would reach the boiling point first. Therefore iron with a difference of 1323° would reach its boiling point first.
Divide the number that visited the gorilla by the total students at the zoo then multiply by 100
90/150 = 0.6
0.6 x 109 = 60%
The answer is 60%
Answer:
m∠XMN = 80°
Step-by-step explanation:
you know that:
4x + 5 + 6x - 10 = 145
solve for x:
10x - 5 = 145
10x = 150
x = 15
Use this information to solve for m∠XMN
6(15) - 10
90 - 10
80
m∠XMN = 80°

0<5xb<5 divide all terms by 5
0<xb<1 divide all terms by x
0<b<x
If you meant 5b as in 5*b then:
0<5b<5 divide all terms by 5
0<b<1
b is infinitely many values between 0 and 1.
