You can set up a ratio of side lengths as follows:
$\frac{63}{x} = \frac{42}{50}$

Now we just solve for x (by cross-multiplying):
$63*50 = 42x$
$x = \frac{63*50}{42} = 75$

So, x = 75 units.

Jerry has been learning to multiply decimals by Integers.

Bogdan [553]

Answer:

Yes

Step-by-step explanation:

Multiplying an integer by 0.01 is the same as Dividing such as :

0.01 = 10^-2

100= 10

For instance :

A number, n = 5 is multiplied by 10^-2

5 * 0.01 = 0.05

Thus, divide the number, n by 100;

5 / 100 = 0.05

Hence, the proof.

In what position would you find the 'leading' runner in a race? In what position do you suppose you would find the 'leading coef

TEA [102]

Since the "leading" runner in a race would be found in the first position, because he or she is in the lead, it means they are first, then I suppose I would find the "leading coefficient" in the first place in a polynomial as well.
