In this question, we've given that using a broken ruler that is missing the first several inches, a student sets the ruler against a nine segment such that the endpoints of the segment are 4 and 5 eighths and 9 and 3 8 respectively.
00:32
What is the length of this segment? so this is a broken ruler.
00:36
And that the segment starts at this point and ends at this point so this point is 4 and 5 eighth while this point here is 9 and 3 16th so we want to get the length of this segment let's call it ab so to get the length of ab we'll take 9 and 3 18 minus 4 and 5 8 this can be written as as follows, you can change this into proper fraction.
01:20
So 9 times 16 is 144.
01:24
So 144 plus 3 is 147.
01:27
So 147 over 16 minus 32 times 5 is 37 8.
01:37
So this will be 147 over 16 minus 37 times 2, which is 74 over 16.
01:48
So let's subtract.
01:50
147 minus 74 is 73 over 16.
01:55
So 73 over 16 can be rewritten as 4 and 9 over 16.
02:07
So the correct answer is the third option 4 and 9 over 16 is the correct length.

In question 2, we are going to draw a 3d ship.
02:20
That has been, that has a given direct views on a isometric dot paper.
02:31
We label the front face and write in the figure the number of cubes needed to make 3d shape.

Okay then this is needed and it's supposed to be uploaded from onedrive and so maybe so that your teacher can see...
