Answer:- $0.75 per kg and $0.50 per kg

let the price of sugar and rice be X and y respectively.

now ,

according to question,

3x + 2y = 3.25 $_____eq.(I)

2x + 2y = 2.50 $______eq.(II)

subtracting eq(II) from eq(I) , we get

2y will be cancelled and remains

X = 0.75 $

therefore , the price of sugar = 0.75 $ per kg.

and

substituting X = 0.75 in eq.(II) , we get

2*0.75 + 2* Y = 2.50

or, 2Y = 2.50- 1.50

or,. Y = 1/2= 0.5

hence , the price of rice is 0.5 $ per gram.

Suppose you work for a large coffee distribution that has a secret coffee blend it sells to local stores. Gazebo blend with Kona
KATRIN_1 [288]

Answer:

12 Pounds

Step-by-step explanation:

The proportion of the secret blend is 90/27. When there is only 40 pounds of gazebo, your proportion looks like this:  40/X. X being pounds of Kona. When you are to simplify 90/27 you're left with 10/3. Cross multiply 10/3 and 40/X to and simply to get 10x = 120, leaving you with 12 as your final answer. Hope this explanation helps.

Which vector best describes the translation below?
Nimfa-mama [501]
<h3>Answer: Choice A)  <9,0></h3>

Explanation:

Focus on one of the points in the figure on the left. Let's say we go for the upper left corner point (-7, 4)

Notice it moves to the corresponding image point (2,4). It has shifted 9 units to the right to follow the translation rule (x,y) \to (x+9, y). We've added 9 to the x coordinate, and the y coordinate stays the same.

This notation can be shortened to <9, 0>

In general, the notation (x,y) \to (x+a, y+b) is shortened to the translation vector notation < a, b >. In this case, a = 9 and b = 0.
