Answer: NO. if a/b > c/d, a/d is not greater than b/c

Step-by-step explanation: The the larger the number in the denominator, the smaller its value as it is represents fractional value, not a whole number. So when a "small" numerator is moved to a denominator, it increases in size, and the large number in the numerator moved to a denominator decreases in size.

Moving the denominator from a smaller fraction to the left side will diminish the value of the new fraction.

3/4 > 1/2 but 3/2 < 4/1

7/8 > 5/6 but 7/6 < 8/5

1/2 > 1/4 but 1/4 < 2/1

BEST GETS BRAINLEST.

We know that <span>the given side lengths are x and the height is x.

Therefore, the area of the base = </span> $A = x * x$

$Formula =\ \textgreater \ volume = length*width*height
$

$To \ find \ the \ volume \ of \ 1 \ slab, \ multiply \ by \ the \ height$ $x -3$

$= x*x*(x-3)$

$Volume \ of \ 25 \ slabs =$ $25*x^2*(x-3)=350000$

$350,000/25 = 14,000$ <span>
</span>
$x^3 - 3x^2 - 14000$ <span>
</span>
$= 25.14$
<span>
</span> $
Rounded => x=25$

Global mean temperature was changing the most rapidly in 2005. How quickly was the temperature changing in 2005

AysviL [449]

The temperature was changing at a rate of 2.925 degrees Celsius in 2005

<h3>How to determine the rate in 2005</h3>

From the graph (see attachment), we have the following ordered pair

(x,y) = (5,14.625)

The above means that, the temperature in 2005 is 14.625 degrees Celsius

So, the rate in 2005 is:

$Rate = \frac{14.625}{5}$
