B, because percent means per 100.
Answer:
District 221221221. I'm not really sure cause last days of snow each school district some of the school tallied
C = -5
8c-6=2c-36
8c-2c=-36+6
6c=-30
Answer:
The lenght of the first piece is 6 feet.
The lenght of the second piece is 18 feet.
The lenght of the third piece is 30 feet.
Step-by-step explanation:
Let be:
the lenght of the first piece (in feet).
the lenght of the second piece (in feet).
the lenght of the third piece (in feet).
You know that the total lenght of the piece of siding is 54 feet. This means that:
Having this expression, you can solve for "x":
Therefore, the lenght of the first piece is 6 feet.
Then:
(The lenght of the second piece is 18 feet)
(The lenght of the third piece is 30 feet)
Those two numbers can't be directly added as long as they're in
radical form. The only way to add them is to find both square roots,
and then add those.
Another twist is the fact that every number has two square roots ...
one positive and the other negative. So there are four possible sums
of (√3 + √4) .
√3 = + or - 1.732051 (rounded)
√4 = + or - 2 (exactly)
The four sums are:
(+1.73205) + (+2) = <em>3.732 </em>(rounded)
(+1.73205) + (-2) = <em>-0.268</em> (rounded)
(-1.73205) + (+2) = <em>+0.268</em> (rounded)
(-1.73205) + (-2) = <em>-3.732</em> (rounded)
