Answer:
Step-by-step explanation:
N = 3rt^4 - 5rz
now factor r out
N = r(3t^4-5z)
divide by r on both sides
N/r = (3t^4 - 5z)
subtract (3t^4)
N/r - 3t^4 = -5z
now divide by -5 to isolate the variable (z)
= z
Well, if we look at a calculator and ask, what is 8% of 3000$ we get the answer of 240 dollars.
3000 - 8% = 2760 therefor we know it removes 240 dollars. So the commission is 240 dollars.
B, because thats 50 grams either direction of the given weight.
The volume of the area is Length x width x height:
25 x 35 x 2/12 = 145.83 cubic feet.
1 cubic foot = 0.037 cubic yards:
145.83 x 0.037 = 5.40 cubic yards.
5.4 cubic yards x 1050 lbs/ cubic yard = 5,665.6 pounds.
Note:
Rounding and conversion may change the answer slightly, but I believe I rounded everything as it should be.
