Answer:
204,335,880 way's
Step-by-step explanation:
590 ways for the 1 st contestant
589 ways for the 1 st contestant
588ways for the 1 st contestant
590×589×588
204,335,880 way's
4 + 100 = 104/ 4+ 10 = 14
We have the equation:
![9x^2-12x+4=0](https://tex.z-dn.net/?f=9x%5E2-12x%2B4%3D0)
so:
![a=9\qquad b=-12\qquad c=4](https://tex.z-dn.net/?f=a%3D9%5Cqquad%20b%3D-12%5Cqquad%20c%3D4)
and:
![\Delta=b^2-4ac=(-12)^2-4\cdot9\cdot4=144-144=\boxed{0}](https://tex.z-dn.net/?f=%5CDelta%3Db%5E2-4ac%3D%28-12%29%5E2-4%5Ccdot9%5Ccdot4%3D144-144%3D%5Cboxed%7B0%7D)
This equation has one solution.
Answer:
Fred has saved $115 while Wilma had saved $230
Step-by-step explanation:
Let the amount saved by Fred be F while the amount saved by Wilma be W
Together, they have saved $345
Mathematically;
F + W = 345 •••••••(i)
We are also told that Wilma has have twice as much money as Fred;
Hence; W = 2F ••••••••(ii)
To get the amount of money they both have, we need to solve the equations simultaneously
Substitute ii into i
F + 2F = 345
3F = 345
F = 345/3
F = 115
But W = 2F
W = 2 * 115
W = 230
