Melinda earned $550 in one month and saved 30% of her earnings. She is saving for a new bicycle which costs $825. How much has Melinda saved so far? At this rate, how long will it take her to save enough money to buy the bicycle?

$165, 5 months total, 4 more months

Step-by-step explanation:

First find 30% of 550 by converting 30% into a decimal to get 0.30. Then multiply 550 by 0.3 to get 165 as her savings each month. To find how ling she has to save, divide 825/165 to get 5 month. She must save for 5 month total or 4 more months to get the bike

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
