Answer:
Part A: That 6 pounds of rice costs $18
Part B: (1,3) represents the unit price
Part C: 4 pounds of rice, because $12/3 equals 4
Step-by-step explanation:
Part A: The first point, 6, is on the amount of rice axis and the second point, 18, is on the total cost axis.
Part B: The unit price means the price for just 1 of something, so if you go to 1 pound of rice on the graph, you see it's at 3 on the total cost axis. Which means that 1 pound of rice costs $3.
Part C: From Part B you know that 1 pound of rice equals $3. So if you spend $12, then you can divide that by $3 to see how many pounds of rice you bought. 12/3 equals 4, so you bought 4 pounds of rice. Or you can count by 3's until you get to 12: 3, 6, 9, 12. That's 4 times so that means you bought 4 pounds of rice.
Answer:
The weight of the package is 1 kilograms.
It will cost $ 13 by both the couriers services.
Step-by-step explanation:
Let the weight of her package is x kilograms
Now, according to the question:
The charges of first Courier = $10 + $3(x)
and The charges of Second Courier = $7 + $6(x)
Also, for x kilograms, both the charges are equal
⇒ $10 + $3(x) = $7 + $6(x)
or, 10 + 3x = 7 + 6x
or, 10 -7 = 6x - 3x
⇒ 3x = 3, implies x = 3/3 = 1
⇒ The weight of the package is 1 kilograms.
It will cost : 10 + 3(1) = $ 13 = 7 + 6(1) by both the couriers services.
Answer:
8 square units and 
square units
Step-by-step explanation:
The area of the triangle ABC is 24 square units.
1. Triangles ABC and FBG are similar with scale factor 
then
2. Triangles ABC and DBE are similar with scale factor 
then
3. Thus, the area of the quadrilateral DFGE is
and the area of the quadrilateral ADEC is
(20,000-18,000)÷20,000=0.1=10%
