Hello from MrBillDoesMath!
Answer: Choice b
Discussion:
Look for corresponding parts in each figure. In this case, the we find
10/ 8 is the ratio of the heights
and
425/x is the ratio of the widths
So 10/8 = 425/x which is choice b.
Thank you,
MrB
It is 1/5 because it is 1 difference on the top and a 5 difference on the bottom number
Inequality:
(3/10) ≥ k - (3/5)
Add 3/5 to both sides:
k ≤ (3/10) + (3/5)
Use LCD:
k ≤ (3/10) + (6/10)
Combine:
k ≤ 9/10
Answer:
255.50
Step-by-step explanation:
If each day the number is doubled, then all you must do is keep on doubling to the ninth day and then add it all together
