Why do we use a coeficient to remove the propotionality

1 answer:

5 0

Constant is the scale term in proportionality. Suppose one variable is dependent on the other and one variable become twice, other becomes also twice and if one becomes half, other too becomes half., but they are two different variables which are no-where linked (like cost(money) vs quantity). Quantity and cost are two different things but they abridge a mathematical relation of proportionality. So in the mathematics to abridge these two different variables, we need something. Constant serves that purpose.

Answer:

$\frac{(\frac{3}{5}*1000) }{6}$

Step-by-step explanation:

First, let's find out how many words Maria has left to write. If she has already finished 2/5 of her essay, she has 3/5ths left to write. We can do 3/5 times 1000 to find out how many words are left.

$\frac{3 }{5} * \frac{1000}{1}$

$\frac{3000}{5}$

$600$

Thus, there are 600 words left to write.

Now to find the amount of time, we can find how take to write 600 words at a pace of 6 words per minute by dividing 600 by 6.

$\frac{600}{6}$

$100$

It will take 100 minutes for Maria to write the rest of her essay. Now let's think about an expression that tells us this information. It sounds like your questions is supposed to have options, but I doesn't seem like you've posted them, no worries however.

So first, the amount she has left to write.

$(\frac{3}{5} * 1000)$

We know this is 600, but we don't have to simplify it for the expression.

Now thinking back to how we found the time, we can divide this '600' by 6.

$\frac{(\frac{3}{5}*1000) }{6}$

This is the expression that shows the amount of time it will take to write the rest of the essay.

$\frac{((1-(\frac{2}{5})*1000) }{6}$ is also a valid solution.

Which list of numbers is in order from least to greatest?<br> 3/6 3/10 3/7

lapo4ka [179]

The list of numbers from least to greatest is

3/10 , 3/7, 3/6

This is because the numerator stays the same across all three of these fractions. However, the denominator is changing, and this proves to be a large difference.

Think about it this way: If you cut a pie into ten pieces, then those slices are going to be smaller than if you cut the pie into seven or six pieces.

Answer:

y=.12x+20

Step-by-step explanation:

The flat rate for the ride is $20, so that will be added on no matter how far you go. The distance is actually extra information in this problem, as it doesn't actually ask for you to solve, so ignore the 50 miles from the airport. It is $0.12 per mile, meaning that actually does depend on the number of miles travelled, so it must be the x coefficient. This leaves you with y=.12x+20.
