Travka [436]

Answer:

Price of rice per gram =  $ 0.006  per gram or 0.6 cents per gram .

Step-by-step explanation:

Given: David wants to make 10 servings, where each serving has 75 grams of rice.

Total quantity of rice required = 10 x 75 = 750 grams

Overall, David spends 4.50 dollars on rice.

i.e. cost of 750 grams of rice = 4.50 dollars

Price of rice per gram =(cost of 750 grams of rice ) ÷ 750

= (4.50 dollars )  ÷ 750

=  $  0.006  per gram.

Price of rice per gram =  $ 0.006  per gram.

What are the coordinates of each point after quadrilateral ABCD is reflected across the y-axis and then translated 2 units down?
dezoksy [38]

Answer:

A" = (3,2)\ \ B" = (-1,1)\ \ C" =(-3,4)\ \ D =(-1,4)

Step-by-step explanation:

Given [Missing]

A = (-3,4)

B = (1,3)

C =(3,6)

D =(1,6)

The first transformation: reflection across the y-axis.

The rule is: (x,y)==>(-x,y)

So:

A = (-3,4) ==>A' = (3,4)

B = (1,3) ==> B' = (-1,3)

C =(3,6) ==> C' = (-3.6)

D =(1,6) ==> D' = (-1,6)

Translation 2 units down

The rule is: (x,y)==>(x,y-2)

So:

A' = (3,4) ==> A" =(3,4-2) =(3,2)

B' = (-1,3) ==> B" = (-1,3-2) = (-1,1)

C' = (-3.6) ==> C" = (-3,6-2) = (-3,4)

D' = (-1,6) ==> D" =(-1,6-2) = (-1,4)

Hence:

A" = (3,2)\ \ B" = (-1,1)\ \ C" =(-3,4)\ \ D =(-1,4)
