Here we use the formula for compound interest given by:
A=p(1+r/100*n)^(nt)
where:
A=amount=
p=principle=12000
r=rate=0.1
n=# terms=2
t=time=10 years
thus;
A=12000(1+0.1/2)^(2*10)
A=31839.6
Answer:
67
Step-by-step explanation:
PEMDAS
For y
since both triangles are congruent,
6y-8=2y+8
4y=16
y=4
For x
5x-5y=2y+7
since y is 4, substitute y to 4
so,
5x-5(4)=2(4)+7
5x-20=15
5x=35
x=7
See how many 5s there are in 47? There are 9 and also a leftover 2 which is your remainder.<span />
Y-9 + y/2 = 180
Add nine to each side
y+y/2=189
Multiply each side by two
2y+y=378
Add the y's together
3y=378
Divide it all by three
y=126
so, Angle B is 126 degrees
I hope that helps!
