Answer:

66 in

Explanation:

the circumference can be calculated as:

$C=d\cdot\pi$

Where d is the diameter and π is 22/7.

So, replacing the values, we get:

$C=21\cdot\frac{22}{7}=\frac{21\cdot22}{7}=\frac{462}{7}=66\text{ in}$

Therefore, the circumference is 66 in.

Mr. Nielsen invested $250,000 in two different automobile companies. The first earned a 5% profit, and the second earned a 10% p

dem82 [27]

Answer: $100,000

Step-by-step explanation:

Let P be the amount he invested in 5% profit .

then 250,000-P be the amount he invested in 10% profit .

The total profit he earns at 5% =5% of P

⇒The total profit he earns at 5 %=0.05P

Now, The total profit he earns at 10% =10% of (250,000-P)

⇒The total profit he earns at 10%= $0.1(250,000-P)=25,000-0.1P$

According to the question,

$3(0.05P)=25,000-0.1P\\\Rightarrow\ 0.15P=25,000-0.1P\\\Rightarrow\ 0.25P=25,000\\\Rightarrow\ P=\frac{25000}{0.25}\\\Rightarrow\ P=100,000$

Thus, the money he invest in the company that made 5%= $100,000
