12/3 = 4 ft
4x2=8inches
Each side of the rug on the scale drawing would be 8 inches long if 2inches is equivalent to 3 feet.
Answer:
It is the third option: (10C1) (20C1( / 50C2.
Step-by-step explanation:
The number of ways of selecting 2 marbles = the number of combination of any 2 marbles in the 50 marbles in the bag and this is 50C2. It is combinations because the order of drawing the marbles does not matter.
The number of combinations of one being red and the other blue = 10C1 times 20C1.
So the answer is (10C1) (20C1( / 50C2.
Answer:

Step-by-step explanation:
4.2*3000
Answer:
185
Step-by-step explanation:
It seems like you're using the Pythagorean theorem, which would mean that b is equal to 
, which is equal to 
. The number beneath the radical symbol is <u><em>185</em></u>.
2/3 = x/(3x + y)
2*(3x + y) = 3*x
2*3x + 2*y = 3x
6x + 2y = 3x
6x - 3x = - 2y
3x = -2y
x/y = -2/3
x : y = -2/3.
