I think the answer is 16 sorry if wrong
So as you know, one gallon has 16 cups, and there's 7 days in a week. So, if you multiple 1.5 by 7 you would get 10.5 cups per week, then divide that by 16 and get .65625 gallons per week.
Answer:
Pythagorean theorem: a^2 + b^2 = c^2
1. we have to find a. b is 12 and c is 15 because the right angle is pointing towards 15 so that is the hypotenuse. then we simply plug the info in the equation we have above.
a^2 + 12^2 = 15^2
a^2 + 144 = 225
a^2 = 81 --> sqaure root to find the answer basically.
a = 9
- we put AD as a so AD = 9
final answer : 9
2. to find AC, simply add AD and DC.
9 + 16 = 25
final answer: AC = 25
3. ABC is not a right triangle because it does not have a right angle. the smaller triangles do, but that does not mean that ABC is a right triangle.
-- let me know if you need any further explanations.
4,500 plus 15% is 5,175 minus 4% is 4,968 so your answer is 4,968.
