Step-by-step explanation:
I = prt is the formula for simple interest
400 = 8000* .02 * t
400 = 160 * t
2.5 = t

Answer:
C
Step-by-step explanation:
Let length of rectangle be "l"
Let width of rectangle be "w"
We know,
LENGTH is 2 MORE THAN WIDTH, we can write:
l = w + 2
Also, note the perimeter is the sum of all 4 sides of a rectangle, thus:
length + width + length + width
Now,
The perimeter is given as 72, so we can write:
l + l + w + w = 72
2l + 2w = 72
We have 2 equations that we need to solve and find the length (l).
The first equation is:
l = w + 2
Rearranging, we have:
w = l - 2
We put this into 2nd equation and find the value of l:
The length is 19 meters, the correct answer is C

Step-by-step explanation:
Given that,
The radius of a circl is 11 m
We need to find the area of the circle. The forcemula for the area of a crcle is given by :
Put all the values,
So, the area of the circle is equal to .
The domain is the list of first numbers: {-4, 2, 6, 7}.
The range is the list of second numbers: {-4, 0, 6, 7}.
_____
It is convenient for many reasons to list the numbers in order, but it is not strictly necessary.
