Answer:
31.5 squared cm
Step-by-step explanation:
Let's start with the triangle part :)
We have a base half a base of 3, so let's add 3 more to make it complete, which gives us 6.
6cm (base) x 6 cm (height) = 36 cm.
Since it's a triangle, we must divide by 2 which gives us 18 cm.
Now let's move on to the circle.
we have a radius of 3.
in order to find area of a circle, we have to do pi x r squared.
We have a radius of 3 so let's square it, which give us 9. after that we multiply 9 by pi.
In the directions, it says use 3 for pi. So we do
3 x 9 which equals 27.
But WAIT- it's a <u>half</u> circle so we <u>divide 27 by 2</u> which gives us <u>13.5 </u><u>cm.</u>
Let's add the two
<u>1</u><u>8</u><u> </u><u>cm </u><u>+</u><u> </u><u>1</u><u>3</u><u>.</u><u>5</u><u> </u><u>cm</u> <u>=</u><u> </u><u> </u><u>3</u><u>1</u><u>.</u><u>5</u><u> </u><u>cm </u><u>squared</u> <u>(</u><u>remember</u><u> </u><u>to </u><u>square </u><u>it </u><u>since </u><u>it's </u><u>area!</u><u>!</u><u>)</u>
<u>I </u><u>hope </u><u>this </u><u>helped!</u><u>!</u><u>!</u><u> </u><u><</u><u>3</u>

Answer:
y > x + 2 and x + 2y < 4
Step-by-step explanation:
The graph to y >x+2 is shown in the attached picture, as well as the graph for 2x+2y<4, which is the same inequality as 0.5x-4< y
When you merge the 2 inequalities you get the graph that you are trying to get, the interception of the 2 regions.
You get these graphs by remembering how to inequalities are drawn, you must leave one variable on one side of the inequality sign, and the rest of terms to the other side.
Then you consider what sign you have, if is a < sign, then, is the region below the terms to the other side of the inequality, and vice versa.
Answer:
If u add probabilities of all possible outcomes that should be one, because classical definition of probability is number of possible out comes divided by total number of outcomes. When you add all probabilities numerator and denominator are equal so answer is one.
