It is 40 becuase points and due
Answer: 34
Step-by-step explanation: 2/5 = 4/10 = 12/30 This means that the machine cuts out 12m lengths for every roll now you just take 400/12 and you get your answer. Now 400/12 will be 33,333... So just round it up to how many she needs aka 34
Answer:
The answer is 12 units.
Step-by-step explanation:
Looking at the figure we see that
![(1).9^2+x^2=SR^2](https://tex.z-dn.net/?f=%281%29.9%5E2%2Bx%5E2%3DSR%5E2)
and
![(3).SR^2+RQ^2=(9+16)^2](https://tex.z-dn.net/?f=%283%29.SR%5E2%2BRQ%5E2%3D%289%2B16%29%5E2)
Now from equations (1) and (2) we have values for
and
so we put those into the equation (3) and get:
![9^2+x^2+16^2+x^2=(9+16)^2](https://tex.z-dn.net/?f=9%5E2%2Bx%5E2%2B16%5E2%2Bx%5E2%3D%289%2B16%29%5E2)
![\rightarrow 337+2x^2=625](https://tex.z-dn.net/?f=%5Crightarrow%20337%2B2x%5E2%3D625)
![\boxed{\therefore x= 12.}](https://tex.z-dn.net/?f=%5Cboxed%7B%5Ctherefore%20x%3D%2012.%7D)
Therefore the answer is 12 units.
