Answer:
AC = 12 cm
Step-by-step explanation:
AB=9 centimeters, you figure out what times what is 9. in this case, it is 3 for A and B. Then you go to BC=12 and 3 for B and 4 for C making it 12 So AC would equal 3x4.

Answer:
An account with 2% annual interest rate and no fees
Step-by-step explanation:
The lowest fee is also associated with the lowest interest rate, so that is the account that is the best deal:
An account with 2% annual interest rate and no fees (2nd choice)
Answer:
Step-by-step explanation:
The formula for the volume of a sphere is given by :
Where
r is the radius of the sphere
The formula for the volume of a cylinder is given by :
Where
r and h is the radius and height of the cylinder
The formula for the volume of a cone is given by :
Where
r and h is the radius and height of the cone
Assuming that angles X and Z are the same as A and C, the Y angle must be 75 degrees. It's because the sum of all three angles in any triangle give us 180 degrees, so:
180 - 45 - 60 = 75 degrees
Answer:
- Yes it is a right triangle
- The side lengths satisfy the Pythagorean theorem equation
Step-by-step explanation:
We can test these numbers to see if they satisfy the Pythagorean theorem equation:
15² = 9² + 12²
225 = 81 + 144 . . . . true
Since the numbers satisy the Pythagorean theorem relation, they belong to a right triangle.
____
You can recognize that the ratio of side lengths is ...
9 : 12 : 15 = 3 : 4 : 5
Further, you can recognize that the side lengths 3, 4, 5 belong to the right triangle with the smallest integer side lengths that satisfy the Pythagorean theorem. Hence the 9 : 12 : 15 triangle is similar (by a scale factor of 3) to a right triangle, thus is a right triangle.
