Give an example of a number that is a whole number, but NOT a natural number.
PLEASE HELP
Answers
Answer:
0
Step-by-step explanation:
Natural numbers or the counting numbers is all the positive, non-decimal numbers. They are 1, 2, 3... and so on. Natural numbers does not include 0.
Whole numbers are all the natural numbers with the addition of 0. In other words, whole numbers are: 0, 1, 2, 3... and so on.
Therefore, the only number that is a whole number and that's not a natural number is 0.
Answer: 0
Step-by-step explanation: The set of counting numbers, {1, 2, 3, 4, ...}
is called the set of natural numbers.
When we include 0 in the set of natural numbers,
the new set, {0, 1, 2, 3, ...} is called the set of whole numbers.
Notice that all natural numbers are
included within the set of whole numbers.
We can represent the relationship between these two
sets of numbers using the diagram shown below.
In fact, 0 is the only whole number that's not a natural number.

The value of the trigonometric ratio cos60 is 1 / 2.
What is trigonometry?The branch of mathematics that sets up a relationship between the sides and the angles of the right-angle triangle is termed trigonometry.
The trigonometric functions, also known as a circular, angle, or goniometric functions in mathematics, are real functions that link the angle of a right-angled triangle to the ratios of its two side lengths.
Given that the value of sin 30° is 1 over 2. The value of cos(90-30) will be calculated as:-
sin(30) = cos(90-30) = cos60
sin(30) = cos(90-30) = 1 / 2
Hence, the value of the cos60 is 1 / 2.

The answer is 90 degrees
Step-by-step explanation:
Both A and B make a right angle, which is 90 degrees.
Hope it helped :)
The value of m∠A + m∠B is 90°
What are vertically opposite angles?It is defined as the angles when two lines intersect each other and at the intersecting point, some pair of angles are formed which we call vertically opposite angles, as the name describes that they have vertically opposite angles.
Three lines intersect to form 5 angles such that:
From the top left ∠B made and after this 90° made.
∠D = 124°
From the figure, we can clearly see ∠A = ∠C (vertically opposite angles)
We can calculate ∠C = 360°-90°-90°-124° ⇒ 56°
Also ∠A = 56°
and ∠B = 90° - 56° ⇒ 34°
Now we can calculate the sum of the angle ∠A+∠B = 56+34 ⇒ 90°
Thus, the value of m∠A + m∠B is 90°

on a scale of map, 5cm represent 60km. if the distance between two points on the map is 8cm, find the actual distance between these points?
Answers
[tex]60 \div 5 = 12[/tex]
[tex]8 \times 12 = 96km[/tex]
Answer:
96 kilometers
Step-by-step explanation:
Let's set up a proportion using the following setup.
scale / actual = scale / actual
The scale is 5 cm to 60 km.
5cm / 60 km= scale/ actual
The distance on the map is 8 cm, but the actual distance is unknown. Therefore, we can say the actual distance is x km.
5 cm/ 60 km= 8 cm/ x km
5/60=8/x
Cross multiply. Multiply the numerator of the first fraction by the denominator of the second. Then, multiply the denominator of the first by the numerator of the second.
(5*x)=(8*60)
5x=8*60
5x=480
5 and x are being multiplied. The inverse of multiplication is division. Divide both sides of the equation by 5.
5x/5=480/5
x=480/5
x=96
x= 96 km
The actual distance between the two points is 96 kilometers.
Find the area of the parallelogram with vertices:________.
P(0,0,0), Q(4,-5,3), R(4,-7,1), S(8,-12,4).
Answers
Answer:
97.98
Step-by-step explanation:
The area of the parallelogram PQR is the magnitude of the cross product of any two adjacent sides. Using PQ and PS as the adjacent sides;
Area of the parallelogram = |PQ×PS|
PQ = Q-P and PS = S-P
Given P(0,0,0), Q(4,-5,3), R(4,-7,1), S(8,-12,4)
PQ = (4,-5,3) - (0,0,0)
PQ = (4,-5,3)
Also, PS = S-P
PS = (8,-12,4)-(0,0,0)
PS = (8,-12,4)
Taking the cross product of both vectors i.e PQ×PS
(4,5,-3)×(8,-12,4)
PQ×PS = (20-36)i - (16-(-24))j + (-48-40)k
PQ×PS = -16i - 40j -88k
|PQ×PS| = √(-16)²+(-40)²+(-88)²
|PQ×PS| = √256+1600+7744
|PQ×PS| = √9600
|PQ×PS| ≈ 97.98
Hence the area of the parallelogram is 97.98

tan45° = 1 , tan60° = [tex]\sqrt{3}[/tex] , then
