Answer:
Triangle ADB is an isosceles triangle that has been split in half. Isosceles triangles are triangles whose base angles are equal and has 2 equal side lengths. For example triangle ADB has AD and DB equal along with m<a and m<b equal
Therefore, if we split this triangle into two half's then they are congruent (the same)
Right triangles have a 90° angle, usually marked by a square
this means that m<DCA is 90°;AD=DB=14m; CB=AC=11; AB=AC+CB=22

Answer: 25 in³
Step-by-step explanation:
We can calculate the volume of the pyramid by first calculating the volume of a prism with the same dimensions, and then dividing by 3 (all pyramids a volume that's of the volume of a prism with the same dimensions).
The volume of a prism is its base area times its height. The base would be a square, so its area is 5², which is 25. The height is 3 inches, making the prism's volume 75 in³.
The volume of the pyramid would be one-third of this value, which is 75 which is 25 in³.

Step-by-step explanation:
A "unit" rate is one that has a denominator of 1 unit.
12 apples : 3 baskets has a denominator of 3, so is not a unit rate. It could be made into a unit rate of 4 apples : 1 basket by dividing the numbers by 3.
Similarly, $5 for 4 muffins has a denominator of 4, so is not a unit rate. The equivalent unit rate is ($5/4) per muffin, or $1.25 per muffin.
All of the other offered choices are unit rates. (See list above.)
