The formula for simple interest is
I=PRT
here P=$1200
R=5% or 0.05
T=4 years
plugging in the formula we get
I=1200*0.05*4=240
Balance after four years =1200+240=$1440
I belive its number one :)
Answer:
<h3>The estimate would be 3-0= nothing, so her answer is not reasonable.</h3>
Step-by-step explanation:
Given the expression written by Elizabeth as 3.3 - 0.21= 1.2, to check if Elizabeth expression is reasonable or not, we need to check if her answer is close to or equal to the answer of the diiferebce between 3.3 - 0.21.
Converting 3.3 and 0.21 to fraction
3.3 = 33/10
0.21 = 21/100
Taking the difference of both fractions

Hence 3.3 - 0.21 = 3.09 ≈ 3.0 (to nearest whole number). Comparing Elizabeth answer which is 1.2 to the answer f=gotten, it can be seen that her answer is far from the right answer with a difference of about 1.8 (3.0-1.2). <u>This large difference makes Elizabeth answer unreasonable.</u>
Answer:
Area of Paris is approximately 28.26 square miles.
Step-by-step explanation:
Given:
Radius of Paris = 3 miles
We need to find the approximate area of Paris.
Also Given:
City of Paris has an almost circular road that goes around the edge.
hence Considering it as Circle we will find the area of circle.
Area of Circle is equal to π times square of the radius.
Framing it in equation form we get;
area of Paris =
Substituting the value of radius we get;
Area of Paris = 
Hence Area of Paris is approximately 28.26 square miles.
