In a given radioactive nuclide, we can easily find the mass number, mass of proton and neutron by subtracting the mass of proton from the mass number. The mass number, mass of proton and mass of neutron of the radioactive nuclide are 131, 56 and 75 respectively.
<h3>Properties of an atom</h3>Data;
In a given atom, the mass number of an atom comprises of the mass of proton and mass of neutron. The atomic number of the element or atom is equal to the mass of the proton.
In this case,
mass number = mass of proton + mass of neutron.
From the calculation above, the mass number, mass of proton and mass of neutron of the radioactive nuclide are 131, 56 and 75 respectively.

Answer:
The percent change in salary from one job to the next is 88.57%.
Step-by-step explanation:
The previous salary of per hour = $8.75 per hour
The current salary of per hour = $16.50 per hour
Change in the salary rate per hour = Current salary - Previous Salary
= $16.50 per hour - $8.75 per hour
=$7.75 per hour
⇒The change in the salary per hour rate is $7.75
Now,
=
or, the change in salary percentage is 88.57%
Hence, the percent change in salary from one job to the next is 88.57%.
Using the graph, it is found that 976 passengers had carry-on luggage that weighed less than 20 lb.
<h3>Graph:</h3>The graph is not given in this problem, but an internet search indicates that the information it contains is as follows:
Hence, the number of passengers with luggage below 20 lb is:
976 passengers had carry-on luggage that weighed less than 20 lb.
