What value of x will make the faction equivent 3/5=x/36

amid [387]

Answer:

x = 21.6

Step-by-step explanation:

<u>Solution by Cross Multiplication</u>

For the equation

35=x36

The cross product is

3×36=5×x

Solving for x

x=3×365

and reducing

x=21.6

<u>Solution by Proportion</u>

Since the equation is an equality

36 ÷ 5 = 7.2

Then it is true that

x ÷ 3 = 7.2

Solving for x

x = 3 × 7.2

x = 21.6

A professor gave her students six essay questions from which she will select three for a test. A student has time to study for o

Alenkinab [10]

The probability that of the questions studied, all three were the test questions selected by the professor is 0.05.

<h3>How to find the probability?</h3>

We can find the probability by dividing the total number of favorable events by the total number of events.

The total number of events is given by $6C_{3}$ .

The total number of favorable events is given by $3C_{3}$ .

The probability is given by = Favorable events/Total number of events

= $\frac{3C_{3}}{6C_{3}}$

= $\frac{1}{\frac{(6)(5)(4)}{(1)(2)(3)} }$

= $\frac{1}{(5)(4) }$

= 0.05

The probability that all three questions are selected by the professor for the test is found to be 0.05.

Therefore, we have found that the probability that of the questions studied, all three were the test questions selected by the professor is 0.05.

1. Point S lies in plane H.

irinina [24]

Points, lines, planes are all undefined terms of geometry

<h3>Point S line in plane H</h3>

To do this, we draw a plane H (represented by a rectangle), and then add a point on the rectangle

<h3>Plane I contains line EL</h3>

To do this, we draw a plane I (represented by a rectangle), and then draw a line on the rectangle

<h3>Plane A, B and C are collinear</h3>

This means that a line passes through points A, B and C or in other words, points A, B and C are on the same line

<h3>Lines x and y intersect at a point M</h3>

This means that point M is a common point on lines x and y or in other words, point M lies on both lines

<h3>Plane A and R intersect at line JI</h3>

This means that line JI lies on both planes

See attachment for the illustration of the 5 activities
