Answer:
2
Step-by-step explanation:
<span>The meeting point of the 3 </span>perpendicular bisectors<span> of a triangle's sides is called </span><span>the circumcenter.
</span><span><span>The circumcenter of an </span>acute triangle<span> is always </span>inside<span> the triangle.
so the answer is "a"

10.5 in the form of a/b = 105/10 = 21/2
Answer:
1, 3, 7
Step-by-step explanation:
A rational number can be written as a ratio or fraction.
1) I wasn't able to determine a fraction for what I'm assuming you meant by 0.878787878787 going on and on so it must be irrational
2) 3.624 can be written as 3 78/125
3) The square root of two is irrational
4) 0.6666666 going on and on can be written as 1/3
5) -5.6 can be written as a fraction too
6) 1/3 is already a fraction
7) Pi is irrational
Hope that helps!
Given is a composite figure where we have a semicircle and a triangle.
To find the area of the semicircle, we need diameter of the circle which is the distance between two given points (2,4) and (2,-3). So the diameter is 4-(-3) = 7 and radius would be 3.5 units.
Area of circle = π·r² = 3.14 × (3.5)² = 38.465
squared units.
So, area of semicircle = 38.465 ÷ 2 = 19.2325
squared units.
To find the area of the triangle, we need base and height of the triangle. The base is same as diameter = 7 and the height would be distance between given point (5,0) and (2,0), so height is 5-2 = 3.
Area of triangle 1/2 * 7 * 3 = 10.5
squared units.
Total area = Area of triangle + Area of semicircle = 10.5 + 19.2325 = 29.7325 squared units.
So, final answer is 29.7325 squared units.
