Answer:
The interest After 6 years is $ 79.03
Step-by-step explanation:
Given as :
The principal amount deposited in account = $ 700
The rate interest earn = 1.8 % per year
The Time period = 6 years
<u>From Compounded Method </u>
Amount = Principal × 
Or, Amount = $ 700 × 
Or, Amount = $ 700 × 
Or, Amount = $ 700 × 1.1129
∴ Amount = $ 779.03
Now , Interest = Amount - Principal
I.e Interest = $ 779.03 - $ 700 = $ 79.03
Hence The interest After 6 years is $ 79.03 , Answer
Answer:
x² + 4xy + 4y²
Step-by-step explanation:
(x + 2y)² = (x + 2y)(x + 2y)
Each term in the second factor is multiplied by each term in the first factor
(x + 2y)(x + 2y)
= x(x + 2y) + 2y(x + 2y) ← distribute both parenthesis
= x² + 2xy + 2xy + 4y² ← collect like terms
= x² + 4xy + 4y²
Answer:
x=22.5°
Step-by-step explanation:
∵it's a rhombus
∴each 2 opposite sides are parallel
∴the angel adjecent angle the angle 3x is equal to the angle 6x
∴ 3x+6x=180
8x=180
⇒x=22.5
