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.
