john lee's savings account has a balance of $1509.After 9 years, what will the amount of interest be at 6% compounded annually?
serious [3.7K]

Answer: $2549

<u>Step-by-step explanation:</u>

A = P(1 + r)ˣ  ; where P is Principal, r is rate, and x is time

Given:

  • P = 1509
  • r = 6%  = 0.06
  • x = 9

A = 1509(1 + 0.06)⁹

   = 1509(1.06)⁹

   = 1509(1.6895)

   = 2549.42

Answer:

  (c)  144 m²

Step-by-step explanation:

The surface area can be calculated from ...

  SA = 2(LW +H(L+W))

  SA = 2((6 m)(6 m) +(3 m)(6 m +6 m))

  = 2(36 m² +(3 m)(12 m)) = 2(36 m² +36 m²) = 2(72 m²)

  SA = 144 m²

_____

<em>Additional comment</em>

The units of area are square meters (m²). The units of volume are cubic meters (m³).

If the side length of a cube is 40 what is the surface area
Elodia [21]
A cube has 6 sides.

A cube is all made up of squares.

So, we need to find the area of one cube and multiply that by 6.

Length * width= area

40*40= 1,600

Multiply that by 6.

1,600*6= 9600

Whatever the unit is after that: in, feet, cm, m, etc- put that after the number with ^2.

9,600 (the unit) ^2

I hope this helps!
