Answer:
(0,12) are the correct y-intercepts.
Answer: 5.5. if you divide you will clearly see it is 5.5 so D
Step-by-step explanation:
Answer:
Length = 10 cm
Step-by-step explanation:
The scaled down diagram would be proportional to the original diagram. That means, we can write a ratio of Length : Width for both and find the unknown.
Let the length of the reduced diagram be "x", thus we can say,
If 30 is to 10 (length is to width), then x is to 4
We can translate this into algebraic equation (ratio) as shown below:
Now, we cross multiply and solve for x:
So,
the reduced diagram has a leaf with length 10 cm
If 4 adults are already in the log, then 150*4 = 600
600 + 100C + 200 = 1500
Re-arranged, 100C = 1500 - 600 - 200
Or simply
100C = 700
Divide each side by 100 to isolate C
So C = 7
So a maximum of 7 children can be seated in the log
All the groups except group 3 can be in the log
