Answer:
D. 1 x 10^2 times
Step-by-step explanation:
F(x)=250+40x
x=number of weeks.
if x=6; then:
f(6)=250+40(6)=250+240=490
Answer: Rosa would save $490.
For the first die, 5 out of 6 are not 1.
That is 5/6.
For the second die, 3 out of 4 are not 1.
That is 3/4.
Multiply 5/6 by 3/4 to get the probability.
5/6 x 3/4 = 20/72
Simplify once to get 10/36.
Do it again to get 5/18.
In decimal form it is 0.2777 and in percent form it is 27.77%.
Hope this helps!
Answer: 12 ROSES
Step-by-step explanation:
If we translate the problem to numbers you will see something like this:
![x*9=108](https://tex.z-dn.net/?f=x%2A9%3D108)
Where:
![x=the number of roses for each arrangements\\9=the amount of arrangements made\\108= the total of roses cut](https://tex.z-dn.net/?f=x%3Dthe%20number%20of%20roses%20for%20each%20arrangements%5C%5C9%3Dthe%20amount%20of%20arrangements%20made%5C%5C108%3D%20the%20total%20of%20roses%20cut)
So you have to solve the equation:
Its a first grade equation, you have to past the value with his product inverse, so the product transform into a division.
Then you have to solve the division between 108 and 9 to obtain the value:
![x=\frac{108}{9} \\\\x= 12](https://tex.z-dn.net/?f=x%3D%5Cfrac%7B108%7D%7B9%7D%20%5C%5C%5C%5Cx%3D%2012)
And thats all.
To verify, now you can replace the x on the equation for the obtained value.
![12*9=108](https://tex.z-dn.net/?f=12%2A9%3D108)
