The answer is <span>C.) 2
The general form of formula is
y = a </span><span>• r^x
y - the total number of bacteria after x period of time
a - the initial number of bacteria
r - growth rate
x - period of time
Let's compare:
</span>y = a • r^x
<span>y = 280 • 2^x
Since r = 2, the growth rate is C.) 2</span>
Answer:
29.97 square feet
Step-by-step explanation:
Given
The length of rectangle = 9 ft
The width of rectangle = 40 in
We have to bring the length and width in same unit. As the area is required in square feet so we will convert width in feet
The width will be divided by 12 to be onverted into feet
So,
Width = 40/12 = 3.33 feet
Now
Area = Length * width
= 9 * 3.33
= 29.97 square feet ..
