The hundredth is the second number to the right of the decimal point. Also, if the number directly to the right of it is 5 or larger, you will have to round up by one.

23.558 becomes 23.56.

In 2004, it was reported that "the relationship between body mass, M, and standard metabolic rate, B, among living organisms rem

lesya692 [45]

The answer is 8884.37 times

In many cases, B is approximately proportional to the three-quarters power of M:
 $B= M^{3/4}$

Elephant:
M1 = 4.6 mt = 4.6 * 1,000,000 g = 4,600,000 g
 $B1= 4600000^{3/4}=99327.24$

Mouse
M2 = 25 g
$B2= 25^{3/4}=11.18$

determine how many times greater the metabolic rate of an elephant is than that of a mouse:
B1/B2 = 99327.24 / 11.18 = 8884.37 times

The equation 2x + 4k − 9 = kx − k + 1 is really a family of equations, because for each value of k, we get a different equation

Olegator [25]

You haven't shared "the given value of x," or, if you have, you haven't drawn attention to it.

Just suppose we were to choose x = 4 as a possible solution and then try to find a value of the parameter k that would make x = 4 an actual solution.

2(4) + 4k - 9 = (4)(4) - (4) + 1

Then 8 + 4k - 9 = 16 - 4 + 1, or 4k - 1 = 13. Then 4k = 14, and k = 14/4, or (after reduction) k = 7/2

If the parameter k equals 7/2, then x = 4 is a solution to the given equation.

To check this out further, start with the proposed solution x = 5 and find k.
