Answer: 68.852459016393 or 68.9 if you round up
Step-by-step explanation:
If you add all the students subjects together you get a total of 41. Then if you add up the total of students who study physics, chemistry, and both you get 20. Then I put those numbers is a percentage calculator then boom you got your answer.
Answer:
Firstly, rewrite the equation:
⅓ (18 + 27) = 81
Substitute x for the given number of it's supposed equivalent.
In this case x = 12.
⅓ (18(12) + 27) = 81
Solve using PEMDAS and simplify what is in the parenthesis first. Then, multiply.
(18 x 12) + 27 = 243
Now, solving using PEMDAS, multiply the total of what you got that was originally in the parenthesis by ⅓ .
⅓ (243) = 81
When you multiple these number they are equivalent to 81.
81 = 81
Since the equation given, when substituted x for 12, is equivalent to 81, this proves that substituting x for 12 makes this equation true.
Answer:
Therefore Nat deposited $500 when he opened the account.
Step-by-step explanation:
Given that Nat opened an account that earns 1.4% simple annual interest. He will earn $21 total interest after t years.
The simple interest formula is

I= interest= $21
P= Principal=?
t= time in year= 3 years.
r = rate of interest= 1.4%= 0.014



=$500
Therefore Nat deposited $500 when he opened the account.
