total cost = 10 * adults + 6 * children
total cost = 10*2 + 6 * 3
total cost = 20 + 18
total cost = 38
Answer:
Given:
To calculate how many electrons have the same mass as one dust particle, divide the mass of a dust particle by the mass of an electron:
![\begin{aligned}\implies \dfrac{\textsf{Mass of a dust particle}}{\textsf{Mass of an electron}} & = \sf \dfrac{7.5 \times 10^{-10}}{9.1 \times 10^{-31}}\\\\& = \sf \dfrac{7.5}{9.1} \times \dfrac{10^{-10}}{10^{-31}}\\\\& = \sf 0.8241... \times 10^{(-10-(-31))}\\\\& = \sf 0.8241... \times 10^{21}\\\\& = \sf 8.2 \times 10^{20}\end{aligned}](https://tex.z-dn.net/?f=%5Cbegin%7Baligned%7D%5Cimplies%20%5Cdfrac%7B%5Ctextsf%7BMass%20of%20a%20dust%20particle%7D%7D%7B%5Ctextsf%7BMass%20of%20an%20electron%7D%7D%20%26%20%3D%20%5Csf%20%5Cdfrac%7B7.5%20%5Ctimes%2010%5E%7B-10%7D%7D%7B9.1%20%5Ctimes%2010%5E%7B-31%7D%7D%5C%5C%5C%5C%26%20%3D%20%5Csf%20%5Cdfrac%7B7.5%7D%7B9.1%7D%20%5Ctimes%20%5Cdfrac%7B10%5E%7B-10%7D%7D%7B10%5E%7B-31%7D%7D%5C%5C%5C%5C%26%20%3D%20%5Csf%200.8241...%20%5Ctimes%2010%5E%7B%28-10-%28-31%29%29%7D%5C%5C%5C%5C%26%20%3D%20%5Csf%200.8241...%20%5Ctimes%2010%5E%7B21%7D%5C%5C%5C%5C%26%20%3D%20%5Csf%208.2%20%5Ctimes%2010%5E%7B20%7D%5Cend%7Baligned%7D)
Therefore, approximately
electrons have the same mass as one dust particle.
