If you are allowed to use a calculator then you only need to press the buttons.
Assuming you cannot use a calculator you need to use approximation techniques. First let us begin by finding the two closest numbers that are perfect squares. In this case 11^2 and 12^2 are the closest square numbers to 129.
11^2 = 121
12^2 = 144
We can already tell that the square root of 129 is closer to 11 than to 12.
Now we need to get even closer.
If you try squaring a number like 11.5 then you can get even closer to 129. When you square 11.5 you get 132.25. Already you can tell that the square root of 129 is close to the square root of 132.25 or 11.5
Now we can get even closer square the number 11.25 and keep on going until one of these numbers when squared is almost or exactly 129. I hope I helped, there really isn't a great way to do this without a calculator, or by using the graph of y=x^2
Answer:
5+2 + 12/5 = $9.40
Step-by-step explanation:
Answer:
let the first and second table box as 12345 and abcde
1,a
2,c
3,e
4,b
5,d
Step-by-step explanation:
you can use
y=mx+b form m is slope , b is y intercept
m with variable x and b without any variable I.e it is real value
He eats 5 peas in 7 minutes. We need to find time taken to eat 60 peas.
So, Time taken to eat 60 peas = (60*7)/5 = 84 minutes or 1 hour 24 minutes.
5 + 4.5 + 2.5 = 12 ÷ 3 = 4
how I know mean is when you add each together then divide it by how many things you added together so we added 3 things together so just divide your answer by 3.
