Answer:
Step-by-step explanation:
Lets illustrate one method by an example:
Find the square root of 12:
The 2 perfect squares around 12 are 3^2 and 4^2 so the square root of 12 is going to be between 3 and 4.
We might predict it to be 3.5
If we square 3.5 we get 12.25 so we are pretty close.
It is less than 3.5 so we might try 3.4 .
Working 3.4^2 out we get 11.56 so we know the square root is between 3.4 and 3.5 Since 12.25 is closer to 12 than 11.56, the square root is closer to 3.5 than 3.4 so we might try 3.46.
This is called the method of trial and improvement and requires you to do long multiplications.
Answer: The correct answer is D
8.4282 * 10⁸
Step-by-step explanation:
(8.47 * 10⁸) - ( 4.18 * 10⁶)
= (8.47 * 10⁸) - (0.0418 * 10⁸)
= 8.4282 * 10⁸

Answer:
The IRS considers them to be part of your employee business expenses, which fall under the category of miscellaneous deductions. Add the cost of tolls, parking, your other car expenses to your other employee business expenses and combine that amount with other miscellaneous expenses.
Step-by-step explanation:
.875 seconds
a=360t
b=280t+(280*.25)
360t=280t+(280*.25)
360t=280t+70
80t=70
t=.875
Answer:
280cm^2
Step-by-step explanation:
I am only looking for the shaded region which is 20 and 14 and 20*14=280
so my final answer will be 280cm^2
