The minimal set of coordinates required to represent any point inside a mathematical space is known as the dimension of the space in physics and mathematics.
What is 3D and 2D ?The terms 2D and 3D describe the precise sizes of a computer workstation. Using the horizontal and vertical (X and Y) axes, 2D is "flat," meaning that there are only two dimensions to the picture, which becomes a line when rotated to the side. The depth (Z) dimension is added in 3D.A two-dimensional form known as a "2D shape" is characterised by its horizontal and vertical axes (x-axis and y-axis)The three spatial dimensions of width, height, and depth are referred to as three dimensions, or 3D. The physical world is three dimensional, as is everything that can be seen there.The rectangle, square, circle, triangle, and any other polygon are a few examples of 2D forms. Cuboid, cube, sphere, cone, prism, cylinder, pyramid, etc. are a few examples of 3D forms.Fill in blanks :
A point has no dimension. it is an abstract idea of a location in space.
A vertex is where two edges meet at a point
A line has edge dimension - length . An edge is a line segment where two faces meet.
A flat plane figures has a 2 dimension - length and width
The 3 points of a 3D object is a plane.
Three dimensional objects have vertices, edges and faces unless they are the geometric solids like cylinders, cones and sphere.
when we talk about line we are looking at the measure of a one dimensional figure.
when we talk about area we are looking at the space inside of a two dimensional figure.
when we talk about volume we are looking at the total space enclosed by a three dimensional figure.

Answers
Answer:
384Step-by-step explanation:
Given,
Dimensions of the rectangular prism = 9ft, 12ft and 4ft
Therefore,
Surface area of the rectangular prism
= 2( lb + bh + lh)
[tex] = 2(12 \times 9 + 9 \times 4 + 12 \times 4) {ft}^{2} [/tex]
[tex] = 2(108 + 36 + 48) {ft}^{2} [/tex]
[tex] = 2 \times 192 {ft}^{2} [/tex]
[tex] = 384 {ft}^{2} [/tex]
Hence,

Answers
Answer:
319 calories
Step-by-step explanation:
Steps to answering this question :
Determine the amount of calories burnt per minute Multiply the answer gotten in the above step by 29 minutes to determine the total calories burnt in 29 minutesCalories burnt per minute = total calories / minutes
220 / 20 = 11 calories
275 / 25 = 11 calories
385 / 35 = 11 calories
11 calories is burnt per minute
Total calories burnt in 29 minutes = calories burnt per minute x 29 minutes
11 x 29 = 319 calories

If p varies jointly as q and r, and p = 150 when q = 18 and r = 5, find q when p = 345 and r = 9.
Answers
Answer:
Step-by-step explanation:
P varies jointly as q and r
p=k* q r
150 =k *(18)(5)
150 = k*(90)
150/90 = k
5/3 = k
find q when p=345 and r =9
p=k* q r
345 = (5/3) * q *9
345 = 45 q / 3
1035 = 45 q
q=23
The required value of the q in the proportionality relationship is given as q = 23.
Given that,
p varies jointly as q and r, and p = 150 when q = 18 and r = 5, find q when p = 345 and r = 9.
What is proportionality?proportionality is defined as between two or more sets of values, and how these values are related to each other in the sense are they directly proportional or inversely proportional to each other.
P varies jointly as q and r
p =k × q r - - - - - (1)
150 =k × 18× 5
k = 5 / 3
Put k = 5/3, p = 345 and r = 9 in equation 1
345 = (5/3) × q ×9
q = 23
The required value of the q in the proportionality relationship is given as q = 23.
