Anita is eating popcorn at the movies. She eats 24 kernels in 10 minutes and 72 kernels in 30 minutes. Which TWO other ratios ca

Neporo4naja [7]

Answer:

$\dfrac{96}{40}$ and $\dfrac{120}{50}$

Step-by-step explanation:

24 kernels in 10 minutes

In 1 minute she can eat $\dfrac{24}{10}=\dfrac{12}{5}\ \text{kernels}$

let $x$ be the number of popcorn and minutes so the rate of eating popcorn is of the form

$\dfrac{x12}{x5}$

So, when $x = 6$ we get

$\dfrac{6\times12}{6\times 5}=\dfrac{72\ \text{kernels}}{30\ \text{minutes}}$

$x$ can be any real number

$\dfrac{10\times 12}{10\times 5}=\dfrac{120\ \text{kernels}}{50\ \text{minutes}}$

$\dfrac{8\times 12}{8\times 5}=\dfrac{96\ \text{kernels}}{40\ \text{minutes}}$

Other two ratios can be $\dfrac{96}{40}$ and $\dfrac{120}{50}$ .

hree vertices of a triangle are located at A (4, 3), B (2, 1), and C (3, 4). Which shows the correct graph of the vertices? A. A

bagirrra123 [75]

Answer: Choice A

Point A is plotted 4 units to the right and 3 units above the origin. Point B is plotted 2 units to the right of and 1 unit above the origin. Point C is plotted 3 units to the right and 4 units above the origin

====================================================

Explanation:

The point A(4,3) means we start at the origin and move 4 units to the right and 3 units up. The x and y axis are separate number lines to mark a location

B(2,1) means we move 2 units to the right and 1 unit up

C(3,4) means we move 3 units to the right and 4 units up

Each time we plot a new point, we always start at the origin.

What is the slope of the line that passes through the points (-6, -8)(−6,−8) and (-14, 4) ?(−14,4)? Write your answer in simples

creativ13 [48]

Answer:

$\huge\boxed{slope=-\dfrac{3}{2}}$

Step-by-step explanation:

The formula of a slope:

$m=\dfrac{y_2-y_1}{x_2-x_1}$

We have two points (-6, -8) and (-14, 4).

Substitute

$x_1=-6,\ y_1=-8,\ x_2=-14,\ y_2=4$

$m=\dfrac{4-(-8)}{-14-(-6)}=\dfrac{4+8}{-14+6}=\dfrac{12}{-8}=-\dfrac{12:4}{8:2}=-\dfrac{3}{2}$
