Next you find the number of females doing phyisics 33-19=14 females
Next you find the number of females doing chemistry by 47-(18 + 14)=15 females
To get the number of males diong chemistry 21-15=6 males
Number of males doing biology 33-(19+6)=8
Then find the remaining totals

Answer: 13000 joules</h3>
This is equivalent to 13 kilojoules.
=======================================================
Work Shown:
m = 65 kg = mass
v = 20 m/s = velocity
KE = kinetic energy
KE = (1/2)*m*v^2
KE = (1/2)*65*(20)^2
KE = 13000 joules
This can be written as 13 kilojoules since "kilo" means "1 thousand"
The abbreviation of the unit "joules" is the letter J.

Answer: 5894.2
Step-by-step explanation:
You'll want to follow PEMDAS to simplify this expression.
1.) P - Parentheses
2.) E - Exponents
3.) M - Multiplication
4.) D - Division
5.) A - Addition
6.) S - Subtraction
We'll start with what's inside the parentheses:
(2.4 × 1018) + (3.4 × 1015)
(2,443.2) + (3,451)
Now all you have to do is add the values together to get your answer!
2,443.2 + 3,451
5894.2
