A terminating decimal means a number that repeats if that helps !
Percent means parts out of 100
x/100=x%
roosters=6
x=percent
6/15=x/100
2/5=x/100
times both sides by 100*5
200=5x
divide both sides by 5
40=x
answer is 40%
To solve for sin(-135), the reference angle will be obtained as follow:
sin(-135)
=-sin(135)
=-sin(180-135)
=-sin 45
hence
the reference angle θ=45°
Answer:
4
Step-by-step explanation:
its 4 because 4x4 is 8 to multiplicity divine fracture root 7/7+4x=4
100% - 30%=70%
70% : $308 = 100% : x
70x = 308x100
70x = 30800
X = $440
Original =$440
