A survey found that 12 out of every 15 people prefer eating out over cooking. If 500 people took the survey, how many people pre

Artyom0805 [142]

Answer:

400 people

Step-by-step explanation:

15 = 12

500 = x

Cross multiply

15x = 12 × 500

Divide both sides by 15

$\frac{15x}{15}$ = $\frac{12 * 500}{15}$ (* means multiplication if you do not know)

$\frac{12 * 500}{15}$ = 100 × 4= 400 people

(PARABOLA? BRAINLIEST + 20 POINTS) A building has an entry the shape of a parabolic arch 22 ft high and 28 ft wide at the base.

Keith_Richards [23]

Check the picture below.

$\bf ~~~~~~\textit{parabola vertex form} \\\\ \begin{array}{llll} y=a(x- h)^2+ k\qquad \leftarrow \textit{let's use this one}\\\\ x=a(y- k)^2+ h \end{array} \qquad\qquad vertex~~(\stackrel{}{ h},\stackrel{}{ k}) \\\\[-0.35em] \rule{34em}{0.25pt}$

$\bf \begin{cases} h=0\\ k=0 \end{cases}\implies y=a(x-0)^2+0 \\\\\\ \textit{we also know that } \begin{cases} x=14\\ y=-22 \end{cases}\implies -22=a(14-0)^2+0 \\\\\\ -22=a(14)^2\implies -22=196a\implies \cfrac{-22}{196}=a\implies -\cfrac{11}{98}=a \\\\[-0.35em] ~\dotfill\\\\ y=a(x-0)^2+0\implies \boxed{y=-\cfrac{11}{98}x^2}$
