First you need to know how many cups of powder you are going to need for the 496 cups of paint you already have
We write this as a ratio
for the 496 cups of paint you will need 99.2 cups of powder.
Continue by seeing how may grams there are in 99.2 cups
write it as a ratio and solve for x again.
now find how many vials you will need
write the ratio and solve
If each sets comes with 12 sets, write the ratio and find the number of sets you will need
you will need 98 sets for this amount of paint.
Answer:
0
Step-by-step explanation:
Quadratic equation
The discriminant is the part of the quadratic formula within the square root symbol: . The discriminant indicates if there are two solutions, one solution, or none.
The discriminant can be positive, zero or negative which determines how roots exist for the given quadratic equation.
So, a positive discriminant tell us that the quadratic has two different real solutions.
A discriminant of zero tell us that the quadratic has two real and equal solutions.
And a negative discriminant tell us that none of the solutions are real numbers.
In this case: 25x^2-10x+1=0
We can see that
a= 25 b=-10 c=1
Using:
We have
the answer is zero, so the quadratic has two real and equal solutions
