Erin earned 6191.50 -6100 = 91.50 in interest in 6 months on a 6100 principal. Then the annual interest rate is ...
I = Prt
r = I/(Pt) = 91.50/(6100·6/12) = .03 = 3%
The interest rate was 3%.
Answer:
If the volume of a cube is 64 cm3, then the side length is 4 cm, because 4x4x4 = 64.
If the side length is 4cm, then the area of one side is 16cm2, and the surface area is 96cm2

Answer:
4x^5+9x^3-5x^2+2x-10
Step-by-step explanation:
(x^2+2)(4x^3+x-5)
4x^5+x^3-5x^2+8x^3+2x-10
4x^5+x^3+8x^3-5x^2+2x-10
4x^5+9x^3-5x^2+2x-10
Answer:
x = 3
Step-by-step explanation:
The triangles are similar.
x + 9 is twice 2x.
x + 9 = 2(2x)
x + 9 = 4x
9 = 3x
x = 3
