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:
x=6
Step-by-step explanation:
When you have 7x+5=5x+17, you try to get the variables on one side and the constants on the other. Subtract 5x from the right and from the left: 2x+5=17. Next, subtract 5 from the left and from the right: 2x=12. The last step is to get rid of the coefficient of x and to do that divide it by the coefficient(in this case divide both sides by 2). After dividing 2x and 12 by 2 you get x=6.
Answer:
27,050
Step-by-step explanation:
Thousand is three zeroes, so we start with 27,000
Hundred is two zeroes, so we add 300
Ones have no zeroes, so we add 5
27,305
but then this is times 10 which adds another zero, so our final result is
27,050
Answer:
12
Step-by-step explanation:
Pythagorean Theorem states that
a² + b² = c²
plug in your terms
9² + b² = 15²
81 + b² = 225
then subtract 81 from 225 to get your b²
b² = 144
then find the square root of 144
the square root is 12 because 12 x 12 = 144
Answer:
x = 9
∠M = 85°
∠N = 85°
Step-by-step explanation:
360 = 95 + 95 + (10x-5) + (8x + 13)
reduce:
18x = 162
x = 9
∠M = 85°
∠N = 85°
