Answer:
9
Step-by-step explanation:
The ratio is 1/2 so the next term would always be half of the previous one.
- 72 times 1/2 is 36
-36 times 1/2 is 18
-18 times 1/2 is 9. So the answer is 9
The square root of 14 rounded to the nearest hundredth without using the calculator can be done this way. Follow these steps:
<span>1. Guess
2. Divide
<span>3. Average
</span></span>
GUESS.
1. Make good guess. We'll just use 2
DIVIDE.
2. Divide 14 by our guess of 2 = 7.
AVERAGE.
3. Average 7 and 2: (7+2)/2 = 4.5
Here, we repeat step 2 using 7 as our new guess, 4.5
2. 14/4.5 = 3.1
3. (3.1 + 4.5)/2 = 3.8
<span>
2. 14/3.8 = 3.7
3. (3.7 + 3.3)/2 = 3.5
2. 14/3.5 = 4
3. (3.5 + 4)/2 = 3.75
2. 14/3.75 = 3.7
3. (3.75 + 3.7)/2 = 3.725
so on and so forth until the pattern remains in 3.7</span>
