Answer:
There are 12 pentapods and 8 Tripods, which in total add up to 84 feet.
Step-by-step explanation:
Given that both the Tripods and the Pentapods have, at least, 3 feet (the Pentapods have 5), and that in total between both groups they add 20 heads and 84 feet, the following logical reasoning can be made:
If there are 20 heads, there are 20 Martians in all. Each of them has, at least, 3 feet, with which in principle the 20 Martians would add up to a total of 60 feet (20 x 3). Therefore, there is a surplus of 24 feet (84 - 60).
If the Pentapods have 2 feet more than the Tripods, the number of Pentapods in the total Martians is determined by that difference. Thus, if there are 24 feet left, there are 12 Pentapods (24/2).
Therefore, in the group of Martians there are 12 pentapods (12 x 5 = 60) and 8 Tripods (8 x 3 = 24), which in total add up to 84 feet (60 + 24).
Answer:
3
Step-by-step explanation:
The radius is half of the diameter so 6/2 is 3
Answer:
192.1%
Step-by-step explanation:
The formula for the amount of interest is ...
i = Prt . . . . . where i is the interest amount, P is the principal, r is the annual rate, and t is the number of years. (Here, we have a fraction of a year.)
Solving for the rate, we have ...
r = i/(Pt)
For "exact" interest, we use 365 days in the year. So, for a time of 19 days of 365, the interest rate is ...
r = $35/($350·19/365) ≈ 1.921 = 192.1%
Answer:
64
Step-by-step explanation:
-4(m-n)^2
when m=3 and n=-1
-4(3-(-1))^2=
-4(3+1)^2=
-4(4)^2=
-4(16)=-64
correct answer is -64
