What is a rational number?

A rational number is a type of real number, which is in the form of p/q where q is not equal to zero. Any fraction with non-zero denominators is a rational number.

Some of the examples of rational numbers are 1/2, 1/5, 3/4, and so on.

The number “0” is also a rational number, as we can represent it in many forms such as 0/1, 0/2, 0/3, etc. But, 1/0, 2/0, 3/0, etc. are not rational, since they give us infinite values.

Answers

Answer:

m = ± 5

Step-by-step explanation:

Given

4² + 2² - (- 3²) = m² - (- 1²) + ([tex]\sqrt{3}[/tex])² ← evaluate exponents

noting that - 3² = - 9 and - 1² = - 1

16 + 4 - (- 9) = m² - (- 1) + 3, that is

20 + 9 = m² + 1 + 3

29 = m² + 4 ( subtract 4 from both sides )

25 = m² ( take the square root of both sides )

m = ± 5

Answer:

1. m∠B=110°

2. 560 cm3

3. Numerical data

4. 2000 cm3

5. 50%

Step-by-step explanation:

1. The explanation of part 1 is given in the attachment.

2. Given dimensions : 10 cm, 8 cm, and 7 cm.

Let Length of cuboid =10 cm

breadth/width of cuboid  =8 cm

height of cuboid = 7cm

Volume of cuboid = length *width* height

=( 10 *8*7) cm3

=(560) cm3

3. Age, Birth date  and weight are the types/examples of "Numerical Data" because these all are describe in terms of numeric values.

4. 1 liter = 1000 cm3   or   1 cm3 = 0.001 liter

1.5 liters =(1.5*1000) cm3 = (15*100) =1500 cm3

1 dm3 =1000 cm3

0.35 dm3 = (0.35*1000) cm3 = (35*10) cm3 =350 cm3

Given expression: 1.5 litre + 0.35 dm3 + 150 cm3 =               cm3

1500 cm3 + 350 cm3 +150 cm3 = 2000 cm3

Answers

Answer:

the answer is b beacause

Step-by-step explanation:

when you multiply 14.95 times 6 it equals b

Answer: 65

Step-by-step explanation:

Let the number of games be x, this means that the cost of x games will be 0.69x.

There is also a one-time registration fee of $14.95 , this means that for Sammy to register and buy game with $60 , the equation will be

14.95 + 0.69x =60

subtract 14.95 from both sides

0.69x = 60 - 14.95

0.69x = 45.05

divide through by 0.69

x = 45.05/0.69

x = 65.28985507

Therefore , the maximum number of games she can buy is 65
