HELP ME OUT how to I Graph 12 + 8y < -20 on a lumber line

Vedmedyk [2.9K]

Answer:

Checkout the screenshot below the explanation.

Step-by-step explanation:

1. First, we have to simplify the inequality.

Step 1: Subtract 12 from both sides.

$8y + 12 - 12 < -20 - 12$
$8y < -32$

Step 2: Divide both sides by 8.

$\frac{8y}{8} < \frac{-32}{8}$
$y < -4$

2. Now that we simplified our inequality down to y < -4, that means that all the values of y are less than -4.

A circle with radius of 5 cm sits inside a 11 cm * 11 cm rectangle.

Nadusha1986 [10]

Answer:

42.43 $cm^{2}$

Step-by-step explanation:

Given:

A circle with a radius of 5 cm sits inside a 11 cm x 11 cm rectangle.

Question asked:

What is the area of the shaded region as shown in the figure ?

Solution:

First of all calculate area of circle and then area of rectangle:-

$Area\ of\ cirle=\pi r^{2}$

$=\frac{22}{7} \times5\times5\\ \\ =\frac{550}{7}\\ \\=78.571\ cm^{2}\\$

<u>As here length an width both are 11 cm, we can say that this is a square.</u>

<u /> $Area\ of\ square=(Side)^{2}$

$=11\times11=121\ cm^{2}$

Now, area of shaded region = Area of square - Area of circle

= 121 - 78.571 = 42.429 $cm^{2}$

Therefore, the area of the shaded region will be 42.43 $cm^{2}$
