Answer:

A). F = $\frac{9C}{5}+32$

B). 374°F

Step-by-step explanation:

A). Formula to convert the temperature from degree centigrade to °F is,

C = $\frac{5}{9}(F-32)$

We have to solve the formula to get the value of F,

9 × C = $9\times \frac{5}{9}(F-32)$

9C = 5(F - 32)

$\frac{9C}{5}=\frac{5(F-32)}{5}$

$\frac{9C}{5}=(F-32)$

F = $\frac{9C}{5}+32$

B). In this part we have to find the value of 190° C in °F.

From the formula given in part (A),

F = $\frac{9\times 190}{5}+32$

= 374°

Therefore, 190°C = 374°F

Assume that a company sold 5.75 million motorcycles and 3.5 million cars in the year 2010. The growth in the sale of motorcycles

OverLord2011 [107]

Answer:

Final answer is approx 6.644 years.

Step-by-step explanation:

Given that a company sold 5.75 million motorcycles and 3.5 million cars in the year 2010. The growth in the sale of motorcycles is 16% every year and that of cars is 25% every year.

So we can use growth formula:

$A=P\left(1+r\right)^t$

Then we get equation for motorcycles and cars as:

$A=5.75\left(1+0.16\right)^t$

$A=3.5\left(1+0.25\right)^t$

Now we need to find about when the sale of cars will be more than the sale of motorcycles. So we get:

$3.5\left(1+0.25\right)^t>5.75\left(1+0.16\right)^t$

$3.5\left(1.25\right)^t>5.75\left(1.16\right)^t$

$\frac{\left(1.25\right)^t}{\left(1.16\right)^t}>\frac{5.75}{3.5}$

$\left(\frac{1.25}{1.16}\right)^t>1.64285714286$

$t\cdot\ln\left(\frac{1.25}{1.16}\right)>\ln\left(1.64285714286\right)$

$t>\frac{\ln\left(1.64285714286\right)}{\ln\left(\frac{1.25}{1.16}\right)}$

$t>6.6436473051$

Hence final answer is approx 6.644 years.
