Answer:
327.4
Step-by-step explanation:
All you have to do to simplify a number written in scientific notation is to move the decimal place to the left (if the number is negative) and to the right (if the number is positive).
Answer:
Your choice is correct.
Step-by-step explanation:
magnitude = √(6² +5²) = √61 ≈ 7.81
direction = arctan(5/6) ≈ 39.81°
The polar coordinates are (7.81, 39.81°).
22/7 = 3.142857...
Let's see if we can beat this using a fraction with 113 as its denominator.
-------
3 x 120 = 360
-------
So, let's try out x = 360:
360/113 = 3.185.... (Too high)
How about x=350:
350/113 = 3.097... (Too low)
Let's try out x = 355:
355/113 = 3.14159292 (Calculator value)
--------
Let's now compare 22/7 and 355/113 to pi:
22/7 = 3.142857...
355/113 = 3.14159292 (Calculator value)
π = 3.141592654
-------
As we can see, 355/113 provides us with a better approximation of π. This means that x=355.
Answer:
The answer is 160. There are 160 boys in the school. Take 360 divide by 9, then multiply by four.
Step-by-step explanation:
The key words you should notice when looking at this word problem are “less than.” This means that the order is flipped, so “3 less than k” means “k minus 3.”
The expression for the ratio is k-3:k+3
Hope this helps
