In fraction form 12/8 = 30/x in fraction: cross multiply 12*x = 240; divide both sides by 12; x= 240/12; x = 20

Using the ratio of perfect squares method, what is square root of 14 rounded to the nearest hundredth? Do not use your calculato
Svetlanka [38]
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>

"What is the value of-3|15-s|+2^3 when s-=3"?
Serggg [28]
You probably made a typing error in writing s = -3 and wrote s - = 3 instead.

The given expression is:

-3|15-s|+ 2^{3}  \\  \\ &#10;-3|15-s|+8&#10;

Substituting the given value of s in the previous equation, we get:

-3|15-(-3)|+8 \\  \\ &#10;=-3|15+3|+8 \\  \\ &#10;=-3|18|+8 \\  \\ &#10;=-54+8 = -46

Thus the value of given expression becomes -46 for s = -3
