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;

  • Mass Number = 131
  • Atomic Number = 56

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.

131=56 + neutron\\neutron = 131 - 56\\neutron = 75

From the calculation above, the mass number, mass of proton and mass of neutron of the radioactive nuclide are 131, 56 and 75 respectively.

3 + 1/3 equals b - 23 State the problem
Viefleur [7K]

Answer:

b=\frac{79}{3} or b=26.33

Step-by-step explanation:

Assuming the question to be finding the value of b.

3+\frac{1}{3}=b-23

Solution:

Rewrite the equation as.

b-23=3+\frac{1}{3}

first we solve right side of the equation.

b-23=\frac{3\times 3+ 1}{3}

b-23=\frac{9+ 1}{3}

b-23=\frac{10}{3}

Add 23 both side of the equation.

b-23+23=\frac{10}{3}+23

b=\frac{10+23\times 3}{3}

b=\frac{10+69}{3}

b=\frac{79}{3}

or

b=26.33

Therefore, the value of b=\frac{79}{3} or b=26.33

Phil had 2 quarters, 1 dime and 3 pennies = 63 cents
Paul had 2 nickles = 10 cents

Total 63 + 10 = 73 cents

If Paul had 1 cent more than Phil, then Paul would have 37 cents and Phil would have 36 cents
but Paul had 10 cents 
10 cents + 27 cents = 37 cents

so 
1 quarter and 2 pennies Phil gave to Paul, total 27 cents

Answer

Phi gave Paul 1 quarter and 2 pennies.
