Brainliest to first answer correct.

suter [353]

Answer:

Option A is correct.

Step-by-step explanation:

The height of the rectangular pack is h1 = 4r

The height of the parallelogram = 2r + the height of equilateral triangles with a side of 2r

The height of equilateral triangle with a side of 2r = (side)/2*√3

=(2r)/2 *√3 = r√3

The height of the parallelogram h2 = 2r+r√3 = r(2+√3)

So,the ratio of h1 to h2 is :

4r : r(2 +√3)

Cancelling r we get

Hence, the ratio is 4 : 2 +√3

Which inequality matches the graph?

Papessa [141]

Given:

The dotted boundary line passes through the points (-3,-8), (1,-2) and (9,10).

Above line is shaded.

To find:

The inequality for the given graph.

Solution:

Consider any two points on the line. Let the two points are (1,-2) and (9,10). So, the equation of the line is:

$y-y_1=\dfrac{y_2-y_1}{x_2-x_1}(x-x_1)$

$y-(-2)=\dfrac{10-(-2)}{9-1}(x-1)$

$y+2=\dfrac{10+2}{8}(x-1)$

$y+2=\dfrac{12}{8}(x-1)$

$y+2=\dfrac{3}{2}(x-1)$

Multiply both sides by 2.

$2(y+2)=3(x-1)$

$2y+4=3x-3$

$2y-3x=-3-4$

$-3x+2y=-7$

Above line is shaded and the boundary line is a dotted line. So, the sign of inequality must be >.

$-3x+2y>-7$

This inequality is not in the equations. So, multiply both sides by -1 and change the inequality sign.

$(-3x+2y)(-1)$

$3x-2y$

Therefore, the correct option is D.
