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.

The point C at a coordinate of (-3, 4) is the center of dilation of shapes WXYZ to W'X'Y'Z'

<h3>How to determine the center of dilation?</h3>

The coordinates are given as:

  • W = (-4, 3) X = (-2, 3) Y = (-4, 1) Z = (-2, 1)
  • W' = (-6, 1) X' = (0, 1) Y' = (-6, -5) Z' = (0, -6)
  • A = (-5, 4) B = (-3, 6) C = (-3, 4) D = (-1, 4)

Next, we plot the points on a coordinate plane

From the plane (see attachment), we can see that the point C at a coordinate of (-3, 4) is at the center of both shapes, and it is 1 unit from WXYZ and 3 units from W'X'Y'Z'.

Hence, the point C is the center of dilation

Solve 4 - 2(-5a - 10)=30 and justify each step
Sergeeva-Olga [200]
First you would do parenthesis according to the PEMDAS(Parenthesis, Exponents, Multiply, Divide, Add, Subtract) Rule

4 -2(-5a -10) = 30

4 + 10a + 20 = 30

Now you need to add 4 and 20 because they are on the same side

24 + 10a = 30

Now subtract 24 on both sides

24 + 10a = 30

-24. -24


10a = 6

Last divide 10 from both sides


10a/10. = 6/10

a= 6/10

Last simplify (optional but recommended)

a = 3/5 or 0.6


Hope this helped :)
