Ratio works for the blank space. Since scale factor and ratio are synonyms. They both refer to the rate of change of something.

If two objects have the same shape, they are called "similar." When two figures are similar, the ratios of the lengths of their corresponding sides are equal so the word would be ratio

If mike gets paid today , than mike with go to the bank . Mike did not get paid today .

Bumek [7]

Remark
The problem with A and B is that one or the other is always possible. So one of them should be your answer.

Comment
This problem depends on whether or not you believe the two statements are connected in some way.

Does he go to the bank to deposit money, or is that the only time he can go to the bank is on the days that he gets paid?

The problem is not clear enough to make a decision. So your answer is either B or D.

I would say your safest choice is D. You don't know for certain what his motivations are.

D <<<<<<< answer.

A sound wave travels through iron at a rate of 5120\,\dfrac{\text{m}}{\text{s}}5120

kipiarov [429]

Answer:

$18432\,km/h$

Step-by-step explanation:

Given: A sound wave travels through iron at a rate of $5120\,m/s$

To find: rate at which the sound wave travel in $km/h$

Solution:

Use the following units conversions.

$1\,m=\frac{1}{1000}\,km$

$1\,s=\frac{1}{3600}\,h$

Now convert $5120\,m/s$ into $km/h$

Therefore,

$5120\,m/s=(\frac{5120}{1000})(3600)\\ =512(36)\\=18432\,km/h$

Suppose X and Y are random variables with joint density function. f(x, y) = 0.1e−(0.5x + 0.2y) if x ≥ 0, y ≥ 0 0 otherwise (a) I

Hatshy [7]

a. $f_{X,Y}$ is a joint density function if its integral over the given support is 1:

$\displaystyle\int_{-\infty}^\infty\int_{-\infty}^\infty f_{X,Y}(x,y)\,\mathrm dx\,\mathrm dy=\frac1{10}\int_0^\infty\int_0^\infty e^{-x/2-y/5}\,\mathrm dx\,\mathrm dy$
