He would have $6,760 in his account after year one.
Do 6,500*0.04=260
6,500+260=6,760
A square field that is 1/4 mile long and 1/4 mile wide has area

So, to know how many of these fields fit in the biggest field, you have to divide their areas:

So, if the farmer divides his land into square fields that are 1/4 mile long and 1/4 mile wide, he will have 16 of these smaller fields.
A.
F(10)= (10)^2-3(10)-5
F(10)=100-30-5
F(10)=65
B.
F(-3)=(-3)^2-3(-3)-5
F(-3)=9+9-5
F(-3)=13
C.
G(2)= -6(2)+1
G(2)= -12+1
G(2)=-11
D.
G(10)=-6(10)+1
G(10)= -60+1
G(10)= -59
#1---> let the number you are trying to find be x for the following questions
30%*x=15
x=15/30%
x=50
#2
10%*x=14
x=14/10%
x=140
#3
(4/32)*100
is the same as (1/8)*100= 12.5%
#4
1%* x=11
x=11/1%
x=1100
by the way * means multiply
