What is the percentage difference between 26 and 14?

topjm [15]

Answer:

0.12%

Step-by-step explanation:

Percent means out of hundred

therefore 26 in percentage is written as

$\frac{26}{100} = 0.26$

=0.26%

and 14 in percentage is written as

$\frac{14}{100}$

=0.14%

percentage difference between 26 and 14 , therefore

=0.26% - 0.14%

=0.12%

A certain motorcycle manufacturer has been building motorcycles for 98 years. Over that period, production has increased steadil

Reika [66]

Answer: The fraction would be 0.53.

Step-by-step explanation:

Since we have given that

$r(t)=A.(1.05)^t$

where, A is the constant initial production rate

t is the time.

For 98 years, the production rate in motorcycles per year would be

$r(98)=A.(1.05)^{98}\\\\r(98)=A.119.27$

For 13 years, the production rate in motorcycles per year would be

$r(98-13)=r(85)=A.(1.05)^{85}\\\\r(85)=A.63.25$

So, the fraction of their total production was built during the last 13 years would be

$\dfrac{r(85)}{r(98)}=\dfrac{63.25}{119.27}=0.53$

Hence, the fraction would be 0.53.
