Answer:
Step-by-step explanation:
Given a number n then the multiplicative inverse is 
The product of a number and it's multiplicative inverse = 1
Given 2, then multiplicative inverse is
15% off means 85% on so I would use .85x · 6 = total monthly cost to represent this problem. The dot represents times (I did not want to confuse things by using x)
Other ways to express this:
6 x .85x
6(.85x)
.85x (6)
Answer:
Step-by-step explanation:
The given expression is
(4×10^8)(4×10^-7)/(4×10^8)
Considering the property of exponents which is expressed as
y^a × y^b = y^(a + b)
Applying the above rule to the denominator of the given expression, it becomes
4×10^8 × 4×10^-7 = 16 × 10^(8 + - 7)
= 16 × 10^(8 - 7)
= 16 × 10 = 160
The expression becomes
16 × 10/(4×10^8)
We would apply the property of exponents which is expressed as
y^a ÷ y^b = y^(a - b)
It becomes
16/4 × 10^(1 - 8)
= 4 × 10^-7
a. A future yen is expected to buy more dollars. It is expected to get stronger.
b. There is insufficient information to determine the difference in inflation rates. We can determine that the expected rate of inflation over the next 3 months in the US is about 102.20/101.19 times that in Japan, higher by a factor of 1.00998. Annualized, this is 1.00998⁴ ≈ 1.04053. That is, the annual rate of inflation in the US is expected to be about 1.0405 times that in Japan, or about 4.05% higher than in Japan. (This will be the approximate difference if the rate of inflation in Japan is given the value 1.)
