Why is a/0 not defined?

1 answer:

3 0

For division operations that are defined, multiplication is the inverse operation. That is if
a/b = c
then
a = b*c

Division by 0 is undefined because it has no inverse operation. If
a/0 = c
it is not true that
a = 0*c

Explain how the Venn diagrams in this lesson show that all integers and all whole numbers are rational numbers

Vinvika [58]

The Venn diagram shows that rational numbers include all integers (-3, -2, -1, 0, 1, 2, 3,) and all whole numbers (0, 1, 2, 3, 4, 5). Inside the <u>rational </u><u>numbers</u> circle is the <u>integer circle</u>, and the <u>whole numbers </u>circle, which concludes that all integers and whole numbers are rational numbers.

Which two triangles are congruent? Complete the congruence statement.

anygoal [31]

Answer:

△ VUW = △ KJI

Step-by-step explanation:

In △ VUW, △ KJI,

UW = JI ( Sides are equal )

∠ VUW = ∠ KJI ( From the diagram )

∠ UWV = ∠ KIJ ( From the diagram )

By ASA rule of congruency,

△ VUW is congruent to △ KJI.

Ted tossed a coin several times and recorded the number of heads and tails in the following table:

sineoko [7]

<h2>Answer:</h2>

Option: D is the correct answer.

D. 0.45

<h2>Step-by-step explanation:</h2>

The results of the experiment are given as follows:

Coin Experiment Side of Coin Number of Tosses

Heads 18

Tails 22

This means that total 40 experiments were performed.

( Since 18+22=40)

Also, the number of times head turn up=18

Hence, the experimental probability of getting heads is:

Ratio of number of times head turn up to the total number of experiments performed.

Hence,

$Probability=\dfrac{18}{40}\\\\\\Probability=0.45$

Hence, the experimental probability of getting head is:

0.45

A number hidden by spilt ink multiplied by 12 equals sixteen thousand, eight hundred and thirty-six. Sixteen thousand, eight hun

Nezavi [6.7K]

Answer:

Step-by-step explanation:

Assume the hidden number is x;

So, if x*12= 16,836

Next, divide both sides by 12 to solve for x;

x= 16,836 / 12

x= 1,403

So the number hidden by spilt ink is 1,403.

Next, to answer the question, divide 16,836 by the hidden number,1403;

16,836 / 1403 = 12

Therefore, it will be equal to 12 which is basically the reverse of the first equation.
