The pitcher for the Robin's throws faster. You know this because you can multiply 112.2 by 60 seconds to equal one minute. You want to get equal minutes, so multiply the answer of 112.2 x 60(6,732) by 60 once again to equal one hour, or sixty minutes. The answer you get(403,920), you divide by 5280 since there are 5280 feet in one mile. You should see that the Bluebird's pitcher throws 76.5 mph which s slower than the Robin's.
The answer is C. Because it takes 5730 years for half of a sample of carbon-14 atoms to decay. It says that 50% of the carbon atoms have decayed so that means that 5730 years have elapsed for that fossil.
I hope that helps.
Answer:
The person who receives the most will get $24
Step-by-step explanation:
Let
x ----> amount received by the first person
y ----> amount received by the second person
z ----> amount received by the third person
we know that
----> equation A

so

----> equation B

----> equation C
substitute equation B and equation C in equation A

solve for y

Find the value of x
Find the value of z

therefore
The person who receives the most will get $24
