The value of nickels is $76.80.
The height of each nickel is 6.25 / 100 = 0.0625 inches.
Divide 8 feet by 0.0625 inches to find that there are
8×12 / 0.0625 = 1536 nickels in an 8 ft stack.
Their value is $76.80.
Nickel is a chemical detail with the symbol Ni and atomic range 28. It is silvery-white lustrous steel with a mild golden tinge. Nickel belongs to the transition metals and is hard and ductile.
Pure nickel, powdered to maximize the reactive surface vicinity, indicates a widespread chemical interest, but large pieces are slow to react with air underneath fashionable conditions because an oxide layer paperwork at the floor stops further corrosion (passivation).

Solution- x=6
15+ 4.5x =42
4.5x = 27
X=6
Answer:
The answer is 1767.15cm^3
Step-by-step explanation:
The formula for finding the volume of a spherical object is 4/3(π)(r^3),where r is the radius of the object. But here only the diameter was given. And diameter=2(r), where r is radius.
So to find the radius, divide the diameter by 2. Since by making r the subject of the equation you get r=diameter/2.
Using the formula
4/3(π)(r^3)=(4π((15/2)^3))/3
=(4π(7.5^3)/3
=(4π(421.875))/3
Since π is 3.141592654
(4π(421.875))/3=1/3(4(3.141592654)(421.875))
=1/3(5301.437603)
=1767.145868
But I rounded off the answer to 2 decimal places and so I got 1767.14
The correct comparison for Weeks 5-8 is higher than Week 1-4, hence, the job satisfaction for Week 5-8 is 17% higher.
<u>Job Satisfaction Score</u> :
- Week 1 = 3.50
- Week 2 = 3.40
- Week 3 = 3.30
- Week 4 = 3.60
- Week 5 = 4.20
- Week 6 = 4.00
- Week 7 = 4.10
- Week 8 = 3.90
<u>Job Satisfaction for week 1 - 4</u> :
- Week 1 + Week 2 + Week 3 + Week 4
- (3.50 + 3.40 + 3.30 + 3.60) = 13.80
<u>Job Satisfaction for Week 5 - 8</u> :
- Week 5 + Week 6 + Week 7 + Week 8
- (4.20 + 4.00 + 4.10 + 3.90) = 16.20
<u>Difference</u><u> between the two categories</u> :
[(Week 5 - 8) - (Week 1-4)] / Week 1-4] × 100%
(16.20 - 13.80) / 13.80 × 100%
(2.4 / 13.80) × 100%
0.1739 × 100%
= 17.39%
Therefore, the job satisfaction for Week 5 - 8 is about 17% higher than Week 1 - 4
