Jody has 2 red marbles, 7 blue marbles, and 8 yellow marbles. what is the ratio of red marbles to blue marbles? a. 17: 2 b. 2: 7 c. 7: 2 d. 2: 17

Thereare 2 red marbles and 7 blue marbles so the ratio of red to blue is B) 2:7

B.2:7

Step-by-step explanation:

Since there are 2 red marbles and 7 blue marbles, you can make a ratio of 2:7.

for ex: the reciprocal of 3/4 is 4/3. it is the opposite.

reciprocal definition:

a mathematical expression or function so related to another that their product is one; the quantity obtained by dividing the number one by a given quantity.

given that triangle abc is transformed two times to get triangle

a"b"c"

first abc is transformed in to a'b'c' as follows:

the coordinates of a are (1,-1) and transformed into a'(-1,1)

similarly b (4,-2) became b'(-4,2) and

c(7,-2) became c'(-7,2)

i.e. (x,y) becomes (-x,-y)

this is nothing but reflection about a point here origin.

thus first transformation is reflection on the origin.

next is exactly shifting 3 units down
