Mr. Gardener's annual interest rate is 8%.
40,000/500,000 = 0.08
155-130=$25
250-125=$125
125/25=5 hours
when 5 hour later it will be the same price, 6 hours later will be higher if using company B hope that helps
The way that i learned this was first set > to = worry about it later
so 9x-7i=3(3x-7u)
so 9x-7i=9x-21u
the x cancel out
so 7i= -21u
now isolate the variable
so
7i/-21=u
so
u=-i/3
<u>Answer</u>
1.156 × 10⁰
<u>Explanation</u>
In indexes,
a⁰ = 1 ⇒ ㏒aⁿ = ㏒1
n㏒a = ㏒ 1
n = ㏒1/㏒a
but ㏒1 = 0
n = 0/㏒a
= 0
∴ So to represent 1.156 to the power of 10 it will be;
1.156 = 1.156 × 10⁰
