en un grupo de estudiantes de tercero de secundaria, 38 son diestros y 6 son zurdos. encuentra la razon de diestros con relacion
svetlana [45]

Answer:

The ratio is \frac{19}{3}

Step-by-step explanation:

The question in English is

In a group of high school third graders, 38 are right-handed and 6 are left-handed. find the ratio of right-handed to left-handed

Let

x -----> number of students that are  right-handed

y -----> number of students that are  left-handed

we know that

To find out the ratio of right-handed to left-handed, divide the number of students that are  right-handed by the number of students that are  left-handed

so

\frac{x}{y}

we have

x=38\ right-handed\\y=6\ left-handed

substitute

\frac{38}{6}

Simplify

\frac{19}{3}

What is the height of an equilateral triangle if the sides are 10
4vir4ik [10]

Answer:

The height of the equilateral triangle is 5\sqrt{3}\ units

Step-by-step explanation:

we know that

An equilateral triangle has three congruent sides, and three congruent angles that each measure 60 degrees

To find out the height of an equilateral triangle, apply the Pythagoras Theorem in the right triangle ABD

Remember that the height of an equilateral triangle bisects the base.

see the attached figure to better understand the problem

AB^2=AD^2+BD^2

substitute the given values

10^2=5^2+BD^2

Solve for BD

100=25+BD^2

BD^2=100-25

BD^2=75

BD=\sqrt{75}\ units

simplify

BD=5\sqrt{3}\ units`

therefore

The height of the equilateral triangle is 5\sqrt{3}\ units
