Answer:
steps below
Step-by-step explanation:
sin θ + cos θ / sec θ + cosec θ
= (sin θ + cos θ) / (1/cos θ+1/sin θ)
= (sin θ + cos θ) / ((sin θ + cos θ)/sin θ*cos θ)
= sin θ * cos θ
3/4(2) + 1/4x = 4
1 1/2 + 1/4x = 4
-1 1/2 -1 1/2
1/4x = 2 1/2
----- ------
1/4 1/4
x= 10 laps
Answer: D

4 rth answer is correct if it is wrong plz comment
Step-by-step explanation:
=14-3/21
=11/21
=
2-1/6
1/6
4-3/12
1/12
1 hour each day is used for test
so 8-1=7 used per day
so commercial is 1 in the 4:2:1 so
4+2+1=7
ok, so 7 units, 7 hours
4 hour for private
2 hour for research
1 hour of commerical
4*5=20=private
2*15=30=research
1*4=40=commercial
20+30+40=90
percent from commercial
40/90=0.44444444444≈44.44% about 44%
