Answer: If he has 3 mystery books, and those are 1/8 of his whole collection, he has 24 books.
Step-by-step explanation:
3 = 1/8 × x
multiply both sides by the reciprocal of 1/8 which is 8/1 ("flipped fraction")
8 × 3 = 8/1(1/8) x <em>When you multiply a fraction by its reciprocal, it produces 1, so it "cancels" in the multiplication</em>
<em>24 = x </em>
<em>This may seem complicated, but understanding the process will help you solve more complicated questions like this in the future, I hope.</em>

The shapes below that have a constant cross-section between a pair of faces are cylinder, cube, sphere, hexagonal, and prism.
<h3>What is the definition of geometry?</h3>
It is concerned with the geometry, region, and density of various 2D and 3D shapes.
A cylinder is a closed solid with two parallel circular bases and a curving surface connecting them.
The shapes have a constant cross-section between a pair of faces like a cylinder.
Hence,cylinder, cube, sphere, hexagonal, and prism are the forms below that have a constant cross-section between a pair of faces.

2/9 chances of getting a yellow because 4 + 3 + 2 is 9 and there is 2 yellow marbles in the bag.
Answer:
143cm
Step-by-step explanation:
Area=2(l+b)
Substitute the values for the variables.
66=2(l+22/5)
66=2xl+2x<u>22</u>
5
66=2l+<u>44</u>
5
Cross multiply
66x5=2l+44
330=2l+44
Collect like terms
-2l = 44-330
-2l = -286
<u>-2l </u>=<u> </u><u>-286</u>
-2 -2
l=143
The missing length is 143m.
