How could you increase the mass of a wooden block?

None of the above. The mass does not change if you change the gravitational constant (moving to Jupiter or Moon), only the weight changes. By cutting it in half you decrease the mass, you do not increase it.

Answer:

$y=\frac{24}{x}$

Step-by-step explanation:

We have been given that a certain function is an inverse proportion. We are asked to find the formula for the function if it is known that the function is equal to 12 when the independent variable is equal to 2.

We know that two inversely proportional quantities are in form $y=\frac{k}{x}$ , where y is inversely proportional to x and k is constant of variation.

Upon substituting $y=12$ and $x=2$ in above equation, we will get:

$12=\frac{k}{2}$

Let us solve for constant of variation.

$12\cdot 2=\frac{k}{2}\cdot 2$

$24=k$

Now, we will substitute $k=12$ in inversely proportion equation as:

$y=\frac{24}{x}$

Therefore, the formula for the given scenario would be $y=\frac{24}{x}$ .

So assuming that the book is 100% the student has read 45% of the book so far in a time of 37 minutes so if you divide 45 by 37 you get 1 minute and 22 seconds per 1% of the assignment
If you multiply this by 100% you get 122 minutes for the total assignment

zvonat [6]

Answer:

3.5 tons

Step-by-step explanation:

Divide the pounds for the male by the amount of tons it is.

8000/4 = 2000

This is how many pounds are in one ton. Divide the weight of the female by this.

7000/2000 = 3.5

The female weighs 3.5 tons.
