27%=27/100
so 27/100=81/x
27x=8100 divide by 27
x=300
that the answer
Answer:
7/12
Step-by-step explanation:
7+5=12
12-5=7
7/12
F(x) = x/4
so
f(-8) = -8/4 = -2
answer
f(-8) = -2
Answer:
18pi units³ or 56.5 units³ (3 sf)
Step-by-step explanation:
pi×r²×h - (4/3)(pi×r³)
r = 3 h = 2r = 6
pi(3²×6 - (4/3)(3³))
18pi units³
Answer:
x = 23
Step-by-step explanation:
the sum of the 3 angles in a triangle = 180°
the third angle forms a straight angle with 100°, hence
third angle in triangle = 180° - 100° = 80°
Summing the 3 angles gives
2x + 3 + 80 + 51 = 180
2x + 134 = 180 ( subtract 134 from both sides )
2x = 46 ( divide both sides by 2 )
x = 23
