Answer:
50 atoms have decayed during that time
Explanation:
The radioactive decay is represented as
Where N is the amount of radioactive element after a certain time period
N0 is the amount of radioactive element during the initial time period
X is the half life of the radioactive element
Substituting the given values in above equation, we get:
atoms
So, 50 atoms of carbon-14 remain are left after decaying for 5700 years.
Hence, atoms of carbon-14 that decay during 5700 years are 100-50 - 50
Answer:
the melting point of ice cream is 74 degrees farenhiet.
Explanation:
How long was each sprinkler used is 30 hours.
<h3>How long was each sprinkler used </h3>
Let x represent how long each sprinkler was used
Hence:
40(x)+15(55-x)=1575
40x+825-15x=1575
Collect like terms
40x+-15x=1575-825
25x=750
Divide both side by 25x
x=750/25
x=30 hours
Therefore the Jenkins used the sprinklers for 30 hours while Green's used it for 25.
The complete question is:
The Jenkins family and the Moore family each used their sprinklers last summer. The water output rate for the Jenkins family's sprinkler was 40l per hour. The water output rate for the Moore family's sprinkler was per 15l hour. The families used their sprinklers for a combined total of 55 hours, resulting in a total water output 1575 of .
