The only number not divisible by anything except itself and 1, was C. 7
Answer:
$435.3
Step-by-step explanation:
Assuming simple interest
Interest, I=Pi/100 where P is principal amount and i is rate of interest in percentage
For $3500, the interest will be 3500*2.2/100=$77
From total target of $151, the person is less 151-77=$74
Taking x as principal and rate of interest as 17% then
0.17x=74
X=74/0.17=$435.2941176470
Rounded off as $435.3
Answer:
the mean is the average, so you would add up all the numbers and then divide by the amount of numbers
so the answer would be 67.5
Answer:
28 square units.
Step-by-step explanation:
Let us divide the shape into two rectangles and a right triangle. The resulting composite figure is attached.
As we see in the figure the area 
of the triangle is
.
The area 
of the bigger rectangle is (it's actually a square )
,
and the area of the smaller rectangle is
.
Therefore, the total area 
of the shape is
(0.4n)(16n) = (0.4)(16)(n)(n) = 6.4n²
Answer: 6.4n²
