Answer:
Least cost per kilogram is "$5 for 2.0 kg"
Step-by-step explanation:
To get cost per kilogram, we divide the cost given by the kg given.
1. We need to divide 4 by 1.5 to get cost per kilogram.
Cost/Kg = 
2. We need to divide 5 by 2.0 to get cost per kilogram.
Cost/Kg = 
3. We need to divide 7 by 2.5 to get cost per kilogram.
Cost/Kg = 
4. We need to divide 8 by 2.5 to get cost per kilogram.
Cost/Kg = 
As we can see, the second option costs the least per kilogram.

Answer:
Yes they are similar. Triangle ABC is similar to Triangle FED. The scale factor from large to small is 3/4 or small to large is 4/3.
Step-by-step explanation:
To determine if two triangles are similar, their corresponding sides create equal ratios.
This ratio is the scale factor depending on which is the pre-image. 3/4 or 4/3.
The two numbers would be 12 and 8 because 12 is 4 more than 8 and so the sum of 12 and 8 is 20.
Answer:
Part 1) An equation is 15.7=3p+1
Part 2) The approximate population in 1950 was 4.9 million people
Step-by-step explanation:
Let
p -----> the population in 1950 in million people
y -----> the population in 2003 in million people
we know that
y=3p+1 -----> equation A
y=15.7 ----> equation B
substitute equation B in equation A and solve for x
15.7=3p+1
3p=15.7-1
3p=14.7
p=4.9
therefore
The approximate population in 1950 was 4.9 million people
