Answer:
27.2mm²
Step-by-step explanation:
Area of a triangle =
* base * height
Base of this triangle = 8mm
Height = 6.8mm
Area = 
= 4mm * 6.8mm
= 27.2mm²

Answer:
21 Feet Long
Step-by-step explanation:
You just reverse how you find a percentage.
1) 40 / 100 = .40
2) .40 * 15 = 6
3) 6 + 15 = 21
I did it this way because I need to find what 40% is to 15. But the trailer isn't 40% of the truck, it's 40% longer than the truck. So, we must add those 2 numbers together getting 21 Ft.

Step-by-step explanation:
Answer:
The answer is D, The objects have the same temperature.
Usually, if two objects are touching each other, the one with the higher temperature may transfer heat to the other object by a method called conduction. During this process, the one with the higher temperature loses heat, while the cooler one gains heat. Their temperature will change until they both have the same temperature, and this can be called thermal equilibrium.
As in "equilibrium", this word means same/balanced, and "thermal" is heat, so size is not related, and changing temperature also does not match with these 2 words. Therefore, the answer should be D.
