Find the sum and the product of the roots of the equation: x^2−37x+27=0

lawyer [7]

Answer:

Sum of the Roots = 37

Product of the Roots = 27

Step-by-step explanation:

Here, the given expression is $x^{2} - 37x + 27 = 0$

Now the general Quadratic Equation is of the form:

$ax^{2} + bx + c = 0$

Here, Sum of the Roots = $-(\frac{b}{a} )$

and the Product of the Roots = $(\frac{c}{a} )$

So, comparing the general equation with the given equation, we get:

a = 1, b = -37 and c = 27

So, Sum of the Roots = $-(\frac{-37}{1} )$ = 37

and the Product of the Roots = $(\frac{27}{1} )$ = 27

A recipe for casserole calls for 2 cups of rice. The recipe makes 6 servings of casserole. how many cups of rice will you need t

ss7ja [257]

You will need 3.333.... cups of rice to make 10 servings of casserole.

Explanation

The recipe which makes 6 servings of casserole, needs 2 cups of rice.

Suppose, you need $x$ cups of rice for making 10 servings of casserole.

Now, the equation according to the ratio of "cups of rice" to the "servings of casserole" will be.....

$\frac{x}{10}=\frac{2}{6}\\ \\ 6x= 2*10=20\\ \\ x=\frac{20}{6}=3.333.....$

So, you will need 3.333.... cups of rice to make 10 servings of casserole.
