Yes.
30 x .30 = 9 cm is a 30% decrease
30-9= 21 cm
Earnings (total) = $75 (bonus) + wt, where w are the hourly wages (a unit rate) and t represents the number of hours worke.
Example: John works 17 hours at $8.90 per hour.
John's wages will be $75 + ($8.90 / hour) (17 hours) = $75 + $151.30.
Answer:
400 divided by 5 is how you get the answer.
Step-by-step explanation:
400 / 5 = 80
80 batches of soup.
Cobalt has an atomic number (Z) of 27, which means the nuclei of all its isotopes have 27 protons. Cobalt 60 has an atomic mass of 60, so it has 60-27 = 33 neutrons.
The mass of 27 isolated protons plus the mass of 33 isolated neutrons would be:
27*(1.007825 u) + 33*(1.008665 u) = 60.497220 u
The actual mass of the nucleus of 60-Co is 59.933820 u.
Mass defect: 60.497220 u - 59.933820 u = 0.563400 u
The mass defect is equal to the binding energy of a nucleus.
using the fact that 1 u = 931.5 MeV/c^2
(0.563400 u)*(931.5 MeV/u) = 524.807 MeV
I got the last answer.
Y = 2x - 2
