Answer:
m = 7
Step-by-step explanation:
3m + 8 + m = 36 , that is
4m + 8 = 36 ( subtract 8 from both sides )
4m = 28 ( divide both sides by 4 )
m = 7

Answer: Choice C</h3>
cos(a - b) = cos(a)cos(b) + sin(a)sin(b)
In this case, we'd have a = 180 and b = q, so,
cos(a-b) = cos(a)cos(b) + sin(a)sin(b)
cos(180 - q) = cos(180)cos(q) + sin(180)sin(q)
cos(180 - q) = -1*cos(q) + 0*sin(q)
cos(180 - q) = -cos(q) + 0
cos(180 - q) = -cos(q)
Step-by-step explanation:
Pythagoras : the lengths are the hypotenuses of the right-angled triangles created by the differences of the x and the y coordinates.
so,
AB² = (0 - -3)² + (2 - 8)² = 3² + (-6)² = 9 + 36 = 45
AB = sqrt(45) ≈ 6.7
CD² = (-2 - 0)² + (2 - -4)² = (-2)² + 6² = 4 + 36 = 40
CD = sqrt(40) ≈ 6.3
The answers is 59/20 because when you calculate it it say 2.95
Answer:
6 : 7
Step-by-step explanation:
Total books = 52
Fiction books = 24
Non-Fiction = Total - fiction
= 52 - 24
= 28
Therefore, the ratio from fiction to nonfiction would be
fiction : nonfiction
= 24 : 28
Simplify
= 12 : 14
= 6 : 7
