razones y proporciones. un pelotero profesional ha bateado 14 imparables , en 40 turnos al bate . hallar la razón entre las vece
ElenaW [278]

Answer:

El pelotero ha bateado imparables en el 35% de sus intentos.

Step-by-step explanation:

Dado que un pelotero profesional ha bateado 14 imparables en 40 turnos al bate, para hallar la razón entre las veces que ha bateado imparables y los turnos que ha tenido que batear se debe realizar el siguiente cálculo:

14 / 40 = X

0.35 = X

0.35 x 100 = 35

Por lo tanto, el pelotero ha bateado imparables en el 35% de sus intentos.

Can someone help me please?
Masja [62]

Given:

A line segment AB.

A point is \dfrac{3}{10} of the way from A to B.

To find:

The coordinates of that point.

Solution:

Section formula: If a point divide a line segment in m:n, then

Point=\left(\dfrac{mx_2+nx_1}{m+n},\dfrac{my_2+ny_1}{m+n}\right)

From the given figure, it is clear that the two end points of the line segment are A(-4,-5) and B(12,4).

Let the unknown point be P. The point is \dfrac{3}{10} of the way from A to B. It means,

\dfrac{AP}{AB}=\dfrac{3}{10}

Let AP and AB are 3x and 10x, then

\dfrac{AP}{PB}=\dfrac{AP}{AB-AP}

\dfrac{AP}{PB}=\dfrac{3x}{10x-3x}

\dfrac{AP}{PB}=\dfrac{3x}{7x}

\dfrac{AP}{PB}=\dfrac{3}{7}

It means, point P divided the line segment in 3:7.

Using section formula, we get

P=\left(\dfrac{3(12)+7(-4)}{3+7},\dfrac{3(4)+7(-5)}{3+7}\right)

P=\left(\dfrac{36-28}{10},\dfrac{12-35}{10}\right)

P=\left(\dfrac{8}{10},\dfrac{-23}{10}\right)

P=\left(0.8,-2.3\right)

Therefore, the coordinates of the required point are (0.8, -2.3).

Find the number of years it would take for $1200 to earn simple interest of $324 at an annual interest rate of 6% per year
topjm [15]

ANSWER

It would take 45 good years

<u>EXPLANATION</u>

We calculate simple interest using the formula,

I=\frac{P\times T\times R}{100}


From the question,


I=324 dollars


R=6%

and

P=120 dollars


We substitute into the above formula

324=\frac{120\times T\times 6}{100}


324=\frac{720\times T}{100}

324\times100=720\times T


\frac{324\times100}{720}=T



\frac{324\times10}{72}=T


45=T


Therefore it would take 45 years.
