Answer:
Dimensions of:
Rectangle A are 6 cm by 4 cm.
Rectangles B are 6 cm by 2 cm.
Step-by-step explanation:
It is given that:
The area of square is 36 cm^2.
Hence, the side of the square is given as:
Hence, the side of square is 6 cm.
Now, as the area of two rectangles A and B are in the ratio:
2:1
This means that, the area of rectangle A is 24 cm^2.
and area of rectangle B is 12 cm^2.
( Since, 36/(2+1)=36/3=12
Area of rectangle A=2×12=24 cm^2.
Area of rectangle B=1×12=12 cm^2. )
Hence, the dimensions of A are:
6 cm by 4 cm.
and the dimensions of rectangle B are:
6 cm by 2 cm.
The value of the quantity after 99 months is 5228.58.
Given that, an initial value = 5900, rate of decay = 0.85% and time period = 7 years.
<h3>What is the exponential decay?</h3>The quantity decreases slowly after which the rate of change and the rate of growth decreases over a period of time rapidly. This decrease in growth is calculated by using the exponential decay formula.
The exponential decay formula formula is
Here, the value
= 5900×
= 5900×0.8862
= 5228.58
Therefore, the value of the quantity after 99 months is 5228.58.
