Answer:
0.45 cm
Step-by-step explanation:
Actual length of the micro chip
![= \frac{1}{40} \times 18 \\ \\ =0.45 \: cm](https://tex.z-dn.net/?f=%20%3D%20%20%5Cfrac%7B1%7D%7B40%7D%20%20%5Ctimes%2018%20%5C%5C%20%20%5C%5C%20%20%3D0.45%20%5C%3A%20cm%20)
2/3 is the answer because 6 in is the model and 4 ft is the actual
let's firstly convert the mixed fractions to improper fractions, and then multiply.
![\bf \stackrel{mixed}{2\frac{1}{2}}\implies \cfrac{2\cdot 2+1}{2}\implies \stackrel{improper}{\cfrac{5}{2}}~\hfill \stackrel{mixed}{3\frac{1}{3}}\implies \cfrac{3\cdot 3+1}{3}\implies \stackrel{improper}{\cfrac{10}{3}} \\\\[-0.35em] ~\dotfill\\\\ -\cfrac{5}{2}\cdot -\cfrac{10}{3}\implies \cfrac{-5\cdot -10}{2\cdot 3}\implies \cfrac{50}{6}\implies \cfrac{25}{3}\implies 8\frac{1}{3}](https://tex.z-dn.net/?f=%5Cbf%20%5Cstackrel%7Bmixed%7D%7B2%5Cfrac%7B1%7D%7B2%7D%7D%5Cimplies%20%5Ccfrac%7B2%5Ccdot%202%2B1%7D%7B2%7D%5Cimplies%20%5Cstackrel%7Bimproper%7D%7B%5Ccfrac%7B5%7D%7B2%7D%7D~%5Chfill%20%5Cstackrel%7Bmixed%7D%7B3%5Cfrac%7B1%7D%7B3%7D%7D%5Cimplies%20%5Ccfrac%7B3%5Ccdot%203%2B1%7D%7B3%7D%5Cimplies%20%5Cstackrel%7Bimproper%7D%7B%5Ccfrac%7B10%7D%7B3%7D%7D%20%5C%5C%5C%5C%5B-0.35em%5D%20~%5Cdotfill%5C%5C%5C%5C%20-%5Ccfrac%7B5%7D%7B2%7D%5Ccdot%20-%5Ccfrac%7B10%7D%7B3%7D%5Cimplies%20%5Ccfrac%7B-5%5Ccdot%20-10%7D%7B2%5Ccdot%203%7D%5Cimplies%20%5Ccfrac%7B50%7D%7B6%7D%5Cimplies%20%5Ccfrac%7B25%7D%7B3%7D%5Cimplies%208%5Cfrac%7B1%7D%7B3%7D)
Answer:
Both zero
Step-by-step explanation:
Adding both eqs
2x+6y-2x-5y=0+0
y=0
Putting in first equation
2x=0
x=0
Answer:
The letter j because the points have to be functioned as a straight line
