Round down to 10. 13 goes to 10.

3 0

You round numbers to the nearest 10 based on the unit value. If it's 5 or above (5, 6, 7, 8, 9), you round up, to the next ten. If it's 4 or below (4, 3, 2, 1, 0), you round down to the same ten.

So 13 has a unit value of 3, so you round down to the same ten, which is literally just the number 10.

Therefore, your final answer is 10 :)

Omar has 2 3/4 cups of dough to make Dumplings. If he uses 3/16 cup of dough for each dumpling,how many whole dumplings can Omar
Brrunno [24]

Omar can make 14 whole dumplings. You change 2 3/4 cups to an improper fraction ( multiply the denominator and add the numerator ) and you get 11/4. Since you need 3/16 cups for one dumpling you have to find the greatest common denominator which is 16. You multiply 4 by 11 to get the numerator and end up with 44/16. Since you need 3/16 for one whole dumping you divide 44 by 3 and get 14.6 repeating. You cannot have a fraction of a dumpling so you round down and get the answer 14.

Find the Values of k for which the following simultaneous equations have no solutions:
iVinArrow [24]

Answer:

k=-\frac{2}{7}

Step-by-step explanation:

The two equations given represent two straight lines in 2-D graph.

The two lines will not intersect if they are parallel.

Hence the two equations will not have solution if the lines are parallel and not coincident.

The condition for 2 lines given by the equations :

ax+by+c=0

dx+ey+f=0 to be parallel but not coincident is:

\frac{a}{d}=\frac{b}{e}\neq\frac{c}{f}

here a=2  b=-3k  c=-1  d=4  e=k+2  f=-5

\frac{2}{4}=\frac{-3k}{k+2}\\k+2=-6k\\k=-\frac{2}{7}

But also:

\frac{-3k}{k+2}\neq\frac{1}{5}

Hence the value of k is -2/7.
