Answer:
1/3
Step-by-step explanation:
Gradient=3/9=1/3
8 ÷ (2 3/4) = 32/11
248 ÷ (32/11) = B. 85 1/4 cubic feet
The cofunction of cos is sin(90-x)
90 degrees is equal to PI/2
The cofunction becomes sin(PI/2 - 2PI/9)
Rewrite both fractions to have a common denominator:
PI/2 = 9PI/18
2PI/9 = 4PI/18
Now you have sin(9PI/18 - 4PI/18)
Simplify:
Sin(5PI/18)
Answer:
x=52
Step-by-step explanation:
160=4+3x
Subtract 4 from both sides
156=3x
Divide 3 from both sides
x=52
56. and 1.6^4
