So just divide 100 by 25 which equals 4 then divide 120 by 30 which also equals to 4 and if the rest equal 4 then its proportional (1)
And then same for 2 and 3 just divided the bottom by the top and if they all get the same answer they are proportion and if one is not the same then it’s not
For the grids if the dots are line diagonally straight and it starts at the 0 then it’s proportional if not then it’s not
Hope this helps :)
The distance around the bulletin board would be 20 feet, because you multiply 6ft 2x and 4ft 2x.
To "rationalize the denominator" is another way to say, getting rid of that pesky radical at the bottom.
we'll simply start by multiplying top and bottom by the "conjugate" of the denominator, recall difference of squares, anyhow, let's do so
Answer:
Step-by-step explanation:
<u>Volume of a cone:</u>
<u>We have:</u>
- V = 1200 cm³
- r = 6 cm
- h = ?
<u>Substitute values and solve for h:</u>
- 1200 = 1/3*3.14*6²h
- 1200 = 37.68h
- h = 1200/37.68
- h = 31.8 cm (rounded)
None of the choices is correct
2x < 18.
The solution to the inequality would then be x < 9.
