Answer:
0.0875 km²
Step-by-step explanation:
1km = 1000m
1km²=1000*1000=1000000m²
6500m²=6500/1000000 km²
= 0.0065 km²
total area= 0.0065+0.08=0.0875 km²
Answer:
a^18 - a^12 + a^6
Step-by-step explanation:
a^24 - a^18 + a^12
------------------------- = a^18 - a^12 + a^6
a^6
It could be radius, circumference, or diameter.<span />
P= k/Q
16.4= k/123
k= 16.4 * 123
k= 2017.2
Therefore, P= 2017.2/Q
Answer:
Isosceles
Step-by-step explanation:
Consider triangle ABC, BD is the median and the altitude drawn to the side AC. This segment (BD) divide the triangle ABC into two triangles: ABD and CBD.
In these triangles:
- AD=DC (because BD is the median);
- ∠ADB=∠CDB=90° (because BD is the altitude);
- BD is common side.
Thus, by SAS postulate, triangles ABD and CBD are conruent. Congruent triangles have congruent corresponding sides. Hence, AB=CB.
If in triangle ABC, AB=BC, then this triangle is isosceles.
