Answer:
a.$7,096
Step-by-step explanation:
- total amount A = s(\frac{(1+\frac{r}{n}) ^{n*t}-1 }{\frac{r}{n} } )[/tex]
[this is the formula used when certain amount is added at regular intervals and if the interest is COMPOUNDED]
(here,
s=deposit added at the end of each quarter= $500
n= number of times interest is compounded per unit 't'=4
t=total time = 3 years
r=interest rate ( expressed in decimal or fraction not in %) = 12/100 = 0.12 )
- A= 500(\frac{(1+\frac{0.12}{4}) ^{4*3}-1 }{\frac{0.12}{4} } )[/tex]
A 
( [1.03]^12= 1.42576 ( approximately) { use calculator for exact values})

Answer:
8
Step-by-step explanation:
68/8.2=8
Roni and Allie are mowing the
grass at the soccer field. Roni has a riding lawn mower and can mow the field
in 30 minutes. Allie is pushing a lawn mower and can mow the field in 75
minutes. This can be solve by
(x/30)+(x/75) =1
X =21.43
<span>So ronie can mow 21.43/30 =
0.71 of the field</span>
So we can add similar exponents
19x^3 can be aded with 4x^3 butnot with 14x
so we use the property that says
a+(b+c)+(a+b)+c
and the other one that says
a+b=b+c to do
a+(b+c)=(a+c)+b so
19x^3+(14x+4x^3)=
(19x^3+4x^3)+14x=
23x^3+14x
