Answer:
The sum of age of the two new boys = 56 years
Step-by-step explanation:
The average age of a group of 13 boys = 13
The sum of age of the 13 boys = 13 * 13 = 169
The average age of a group of 15 boys = 15
The sum of age of the 15 boys = 15 * 15 = 225
The sum of age of the two new boys = 225 - 169 = 56 years
50 x 50= 2500.............

Answer:
Shaquille O'Neal's height= 2,160,000,000 nm
= 2.16 × 10^9 nm
Completed question;
The basketball player Shaquille O'Neal is 7 feet 1 inch tall, which is equivalent to 216 centimeters a nanometer (nm) is a unit of measurement that is one-billionth of a meter, convert his height to nanometers.
Step-by-step explanation:
Given;
Shaquille O'Neal's height= 216cm = 216 × 1/100 m = 2.16m
Since, a nanometer (nm) is a unit of measurement that is one-billionth of a meter.
1 m = 1 billion nanometers
So,
2.16m = 2.16 billion nm = 2160000000 nm
Shaquille O'Neal's height= 2160000000 nm
= 2.16 × 10^9 nm
