A software company keeps a ratio of 2.5 testers to every 10 software developers. If the company hires 20 developer in one year,
pochemuha

Answer:

They will need to hire 5 testers.

Step-by-step explanation:

This question can be solved using a simple rule of three.

For each 10 developers, we need 2.5 testers. So how many testers are needed for 20 developers?

10 developers - 2.5 testers

20 developers - x testes

10x = 20*2.5

10x = 50

x = \frac{50}{10}

x = 5

They will need to hire 5 testers.

Ndicate the equation of the line through (2, -4) and having slope of 3/5.
lord [1]

\bf (\stackrel{x_1}{2}~,~\stackrel{y_1}{-4})~\hspace{10em} slope = m\implies \cfrac{3}{5} \\\\\\ \begin{array}{|c|ll} \cline{1-1} \textit{point-slope form}\\ \cline{1-1} \\ y-y_1=m(x-x_1) \\\\ \cline{1-1} \end{array}\implies y-(-4)=\cfrac{3}{5}(x-2) \implies y+4=\cfrac{3}{5}x-\cfrac{6}{5} \\\\\\ y=\cfrac{3}{5}x-\cfrac{6}{5}-4\implies \implies y=\cfrac{3}{5}x-\cfrac{26}{5}

Volume of a cylinder is \pi r^2h, where r is the radius and h is the height.

This comes from the area of a circle being \pi r^2. A cylinder is the area of the base circle multiplied by its height.

Using this formula, the volume of the given cylinder is
\pi r^2(3r) \\
=  3 \pi r^3

Find the compound interest on ₹ 31,250 at 12% pa for 2 1/2 years
IRISSAK [1]

Answer:

42,183

Step-by-step explanation:

We will use the Continuous Compounding Interest since a regular interval was not stated.

P(t) = Pe^(rt)

We will plug in the variables to the formula

P(t) = 31250 * e^(.12 * 2.5)

We can simplify and evaluate the compound interest.

P(t) = 42183.08
