Answer:
The irrational numbers are √1/2, √1/8 and √1/10
Step-by-step explanation:
Rational numbers are numbers that can be written as a simple ratio. If the ratio is simplified further into decimal, the numbers in the decimal do not occur repeatedly.
Irrational numbers are opposite. Irrational numbers are are numbers that cannot be written as a simple ratio. If the ratio is simplified further into decimal, the numbers in the decimal occur repeatedly.
Looking at the numbers given above,
1) √1/16 = 1/4 = 0.25
It is rational because it is expressed in simple ratio and the numbers in the decimal do not occur repeatedly.
2) √1/2 = 1/√2 = 0.70710678119
It is irrational because it cannot be expressed in simple ratio and the numbers in the decimal occur repeatedly.
3) √1/8 = 1/√8 = 0.35355339059
It is irrational because it cannot be expressed in simple ratio and the numbers in the decimal occur repeatedly.
4) √1/10 = 1/√10= 0.31622776602
It is irrational because it cannot be expressed in simple ratio and the numbers in the decimal occur repeatedly.
5) √1/4 = 1/4 = 0.5
It is rational because it is expressed in simple ratio and the numbers in the decimal do not occur repeatedly.
Answer:
84 ÷ -12 = -7
21 ÷ -3 = -7
Step-by-step explanation:
49 ÷ -7 = -7
Means that __ ÷ __ must equal -7
There are many options, here are a few:
84 ÷ -12 = -7
or -84 ÷ 12 = -7
21 ÷ -3 = -7 etc
The Venn diagram is given below. Then the number of students who have brother and sister will be 6.
<h3>What are sets?</h3>
A set is a group of clearly specified components. The number of items in a finite set is denoted by a curly bracket.
In a class of 20 students:
11 have a brother, 9 have a sister, and 6 have neither.
Then the Venn diagram will be
11 – a + a + 9 – a = 20 – 6
20 – a = 14
a = 6
The Venn diagram is given below.
