Now

\\ \sf\longmapsto y+40=180

\\ \sf\longmapsto y=180-40

\\ \sf\longmapsto y=140

Now

\\ \sf\longmapsto x+y=140+50=190

Ashley uses 1/4 package of raisin for a fruit cake. She then uses 1/9 of the remainder for muffins. What fraction of the package
Flura [38]
\text {Fruit cake = } \dfrac{1}{4}

\text {Raisin left = } 1 -  \dfrac{1}{4} = \dfrac{4}{4} - \dfrac{1}{4} = \dfrac{3}{4}

\text {Muffins  = } \dfrac{1}{9}  \times  \dfrac{3}{4} =  \dfrac{3}{36} =  \dfrac{1}{12}

\text {Raisin left = } \dfrac{3}{4}  - \dfrac{1}{12} =\dfrac{9}{12}  - \dfrac{1}{12} = \dfrac{8}{12}  -= \dfrac{2}{3}

Answer: She has 2/3 of the package left.

You can use the _______ of a quadratic equation to determine the number and type of solutions
Dennis_Churaev [7]

Answer: Discriminant.


Step-by-step explanation:

1. The quadratic formula is:

x=\frac{-b+/-\sqrt{b^{2}-4ac}}{2a}

2. And the discriminant is inside the square root:

b^{2}-4ac

2. Then, if the discriminant is negative, the quadratic equation does not have real solutions, it has two imaginary solutions. If the discriminant is zero the quadratic has one solution. If the discriminant is positive, the quadratic equation has two distinct solutions.
