First calculate the area of the floor, this would be 30*50 = 1500 square feet
Now multiply the area by the cost for each square foot, so 1500*0.5 = $750
Tan theta= opposite/adjacent = -12/5
csc theta = hypotenuse/opposite = -13/5
in the expressions above,the value of opposite side differs in both cases.
Hence,the statement is false <span />
Step-by-step explanation:
such candles are cylinders.
the volume of a cylinder is
pi×r²×height
the volume of candle 1 is
pi×3.1²×6.3 in³ = pi × 60.543 in³
the volume of candle 2 is
pi×3.9²×3.9 in³ = pi × 59.319 in³
so, candle 1 has the larger volume.
1 = 10
2 = 12
3 = 14
4 = 16
5 = 18
6 = 20
