Answer:

Step-by-step explanation:

Given equation is,

a). y = $\frac{6}{x}$

x 0.5 1 2 3 4 5 6

y $\frac{6}{0.5}=12$ $\frac{6}{1}=6$ $\frac{6}{2}=3$ $\frac{6}{3}=2$ $\frac{6}{4}=1.5$ $\frac{6}{5}=1.2$ $\frac{6}{6}=1$

b). By plotting the input-output values on the graph we get the curve as shown in option C.

Therefore, Option C will be the answer.

A rectangle or piece of paper has a width is 3 inches less than its link it is cut in half along a diagonal to create two congru

kolezko [41]

The length and width of the rectangle is 11 in and 8 in respectively.

Step-by-step explanation:

Given,

The width of a rectangle is 3 in less than the length.

The area of each congruent right angle triangle = 44 in²

To find the length and width of the rectangle.

Formula

The area of a triangle with b base and h as height = $\frac{1}{2}$ bh

Now,

Let, the width = x and the length = x+3.

Here, for the triangle, width will be its base and length will be its height.

According to the problem,

$\frac{1}{2}$ ×(x+3)×x = 44

or, $x^{2} +3x = 88$

or, $x^{2} +3x-88 = 0$

or, $x^{2}$ +(11-8)x-88 = 0

or, $x^{2}$ +11x-8x-88 =0

or, x(x+11)-8(x+11) = 0

or, (x+11)(x-8) = 0

So, x = 8 ( x≠-11, the length or width could no be negative)

Hence,

Width = 8 in and length = 8+3 = 11 in

WILL GIVE BRAINLIEST!!!

Andrews [41]

The 13 stripes alternate red and white: 7 red and 6 white.
Each of 13 stripes is (39 in. / 13) = 3 in. wide.
4 of the 7 red stripes are 39 in. long. The other 3 are 65 in. long.

The total area (l*w) of the flag is (65 in.)*(39 in.)=2535 sq. in.

The red stripes make up an area (l*w) that is:
4*(area of short stripes) + 3*(area of long stripes)
Red area is 4*(39*3) + 3*(65*3) = 1053 sq in.

The fraction of the flag that is red is:
1053 sq. in. / 2535 sq. in.
