Hello,
A: 4 , 4 , 4 not right triangle
B: 4 , 6.93 , 8 or 4²+6.93²=64,0249 ≈64=8²
C: 11.2 , 16.2 , 19.2 or 11.2²+16.2²=387,88 =(19,69...)²
The best choice is B
Answer:
![P=\$65,062.35](https://tex.z-dn.net/?f=P%3D%5C%2465%2C062.35)
Step-by-step explanation:
we know that
The simple interest formula is equal to
![I=P(rt)](https://tex.z-dn.net/?f=I%3DP%28rt%29)
where
I is the interest Value
P is the Principal amount of money to be invested
r is the rate of interest
t is Number of Time Periods
in this problem we have
![t=(83/365)\ years\\ P=?\\ I=\$680.57\\r=0.046](https://tex.z-dn.net/?f=t%3D%2883%2F365%29%5C%20years%5C%5C%20P%3D%3F%5C%5C%20I%3D%5C%24680.57%5C%5Cr%3D0.046)
substitute in the formula above
![680.57=P(83/365)(0.046)](https://tex.z-dn.net/?f=680.57%3DP%2883%2F365%29%280.046%29)
![680.57*365=P(83)(0.046)](https://tex.z-dn.net/?f=680.57%2A365%3DP%2883%29%280.046%29)
![P=680.57*365/[(83)(0.046)]](https://tex.z-dn.net/?f=P%3D680.57%2A365%2F%5B%2883%29%280.046%29%5D)
![P=\$65,062.35](https://tex.z-dn.net/?f=P%3D%5C%2465%2C062.35)
Step-by-step explanation:
60 cookies with 4 cups
that means 60 per 4 = 60/4 = 15
and that means that he can make 15 cookies with 1 cup.
that is clear : from 60/4 we immediately know 15/1.
and now, as we know how many cookies can be made with 1 cup, it is easy to say how many cookies can be made with 3 cups. right, 3 times a much.
so, yes, we multiply 15 by 3 and get 45 cookies as answer.
