HELLPPP????? PLEASEEEESSSS
Verdich [7]

Answer:

\boxed{43.48 \, \%}

Step-by-step explanation:

The formula for calculating percentage is

\text{Percentage} = \dfrac{\text{Part }}{\text{Whole}} \times 100 \, \%

The "part" is the number of single-shot espressos

The "whole" is the total number of espressos.

\begin{array}{rcl}\text{Total espressos} & = & 46\\\text{-Single-shot espressos} & = & 26\\\text{Double-shot espressos} & = & 20\\\end{array}

\text{ \% Double-shot}=\dfrac{20}{46} \times 100 \, \% =\mathbf{43.48 \, \%}\\\\\boxed{\mathbf{43.48 \, \%}} \text{ of the espressos were double-shot}

Let $r$ and $s$ be the roots of $3x^2 + 4x - 12 = 0.$ Find $r^2 + s^2.$
Paul [167]

We can factorize the quadratic as

3x^2 + 4x - 12 = 3 (x - r) (x - s)

and expand the right side to get

3x^2 + 4x - 12 = 3x^2 - 3(r + s) x + 3rs

\implies r + s = -\dfrac43 \text{ and } rs = -4

Then we find

(r + s)^2 = r^2 + 2rs + s^2 \implies r^2 + s^2 = \left(-\dfrac43\right)^2 - 2(-4) = \boxed{\dfrac{88}9}
