X is the son's age = 20

1 + 3x
= 1 + 3(20)
= 1 + 60
= 61

so father's age = 61
son's age = 20

A cylindrical well is 15 meters deep and has a diameter of 1.6 meters. Approximately how many cubic meters of soil were dug out

Lisa [10]

We can dig out the soil from the well equal to volume of well.

Height(h) of well is = 15 meters.

Diameter = 1.6 meters.

So radius(r) = $\frac{1.6}{2} = 0.8$ meter.

As well in cylindrical shapes.

So volume of well = $\pi r^2h$
                               = $\pi * (0.8)^2 * 15$
                                $= 9.6 * \pi$
In general $\pi = 3.14$

So volume of well is = $9.6 * 3.14$
   $= 30.144$ cubic meter.

So we can dig out 30.144 cubic meter soil from well.

Suppose that an individual has a body fat percentage of

KonstantinChe [14]

Namely, how much is 18.3% from 188? well if we take 188 to be 100%, then

$\bf \begin{array}{ccllll}
amount&\%\\
\text{\textemdash\textemdash\textemdash}&\text{\textemdash\textemdash\textemdash}\\
188&100\\
x&18.3
\end{array}\implies \cfrac{188}{x}=\cfrac{100}{18.3}\implies \cfrac{188\cdot 18.3}{100}=x$

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
