Answer:
V = 40 1/2cm^3 OR 40.5cm^3
Step-by-step explanation:
A Prism is given it's name from the nature of it's base.
If it's a triangular base, it's call a TRIANGULAR PRISM.
If the base is of a rectangle shape, it's called a RECTANGULAR PRISM and so on!
From the question given, we'll treat the prism as a RECTANGULAR PRISM.
The volume of a prism is expressed as:
V = Bh
B means the BASE AREA
h means the height
Base Area for the prison is RECTANGLE.
Area of a rectangle (A) = lw
l means height
w means weight.
From the dimensions given in the question:
Length = 4 1/2cm
Width = 6cm
Height = 1 1/2cm
Let's start with the BASE AREA of the Rectangle
A = lw
A = 4 1/2cm * 6cm
A = 9/2cm * 6cm
A= 27cm^2
Volume = Base Area (A) * height (h)
V = Bh
V= 27cm ^2 * 1 1/2 cm
V = 27 * 3/2
V = 81 / 2
V = 40 1/2cm^3 OR 40.5cm^3
Answer:
cos (a+b)= cos a cos b - sin a sin b

I had to answer this question too, but I don't know the explanation. I just saw it in this Khan Academy video. https://www.khanacademy.org/math/precalculus/x9e81a4f98389efdf:trig/x9e81a4f98389efdf:angle-addition/v/cosine-addition-identity-example
Answer:
Th number of pages is 33
Step-by-step explanation:
The ratio of the number of pages of text shown in the illustration is 3:2. This implies that for every 2 pages of illustrations, there are 3 pages of text. Therefore, for 22 pages of illustration we shall have;
2 page of illustration = 3 page of text
Then
22 page of illustration = x pages of text
Then by Cross multiplication
![22 \times 3 = x \times 2](https://tex.z-dn.net/?f=22%20%5Ctimes%203%20%3D%20x%20%5Ctimes%202)
![66 = 2x](https://tex.z-dn.net/?f=66%20%3D%202x)
x =![\frac{66}{2}](https://tex.z-dn.net/?f=%5Cfrac%7B66%7D%7B2%7D)
x = 33
