Here, She invests in a CD with an annual interest rate of 6.90% compounded quarterly.
Let the initial amount or principal = P
And, Let after t years it is doubled.
Therefore,

Answer:
x = 55
y = 70
Step-by-step explanation:
since it's all sides are equal its an equilateral triangle
each angle of an equilateral triangle is 60°
therefore,
y - 10 = 60 => y = 60 + 10
y = 70
x + 5 = 60 => x = 60 - 5
x = 55

Answer:
81 1-inch cubes
Step-by-step explanation:
Cube root of 729 is 9
9 x 9 = 81
Further explanation:
A cube has 3 measures (there are all the same) to solve for the volume. If the volume is 729, and it is a cube, you would solve for the cube root, because all the numbers are the same. Then, we would get 9. Now, since a cube is made up of faces, and each one is a square, we do 9 x 9 to get the area, which is the answer, because 1-inch cubes are literally just units.
