Joe found the area of a triangle by writing A=1/2(11 in.)(4 in.), while Kaitlin found the area by writing A=1/2(3 in.)(4 in.) + 1/2( 8 in.)(4 in.). explain how each student approached the problem.
Answers
Answer 1
Answer:
ok so remember distributive property
a(b+c)=ab+ac so
1/2(11)(4)=1/2(3)4+1/2(8)(4)
aka
(1/2*4)(11)=(1/2*4)(3+8)(1/2*4)(3)+(1/2*4)(8)
the 1/2*4 bit was the 'a' and the 3 was b and 8 was c
a(b+c)=ab+ac so
1/2(11)(4)=1/2(3)4+1/2(8)(4)
aka
(1/2*4)(11)=(1/2*4)(3+8)(1/2*4)(3)+(1/2*4)(8)
the 1/2*4 bit was the 'a' and the 3 was b and 8 was c

I=PRT
I=interst
P=present amount
R=interest rate
T=time in years
we know that
P=8000
R=2%=0.02
we also know that we want 400 in interst or I=400
we need to knw T
so
400=8000(0.02)(T)
400=160(t)
divide both sides by 160
2.5=T
