Independent variables, which can be controlled or manipulated; dependent variables, which (we hope) are affected by our changes to the independent variables
1.2+I that the answer is correct
Answer:
D
Step-by-step explanation:
D. All of the terms in set D are rational, as they can be expressed as decimal/fractions. sqrt25 is rational, because it simplifies to 5, which is rational.
Answer:
Step-by-step explanation:
d = distance from hive to flowers, in feet
flying time = 23 min - 18 min = 5 min = 300 sec
time flying to flowers = d ft × (1 sec)/(10 ft) = (d/10) sec
time flying to hive = d ft × (1 sec)/(6 ft) = (d/6) sec
d/10 + d/6 = 300 sec
:::::
d/10 + d/6 = 3d/30 +5d/30 = 8d/30 = 300
d = 300×30/8 = 1,125 ft
<span>Sin (x) = Cos (90 - x)</span>
<span>sin(2A) = cos (90 - 2A)
=cos (3A)
90 - 2A = 3A
5A=90
A=18</span>
