(xii) NH₂ + Cl₂ →→→→NH₂CI+ N₂
(xiv) NaOH + Cl₂ →→ NaCl + NaCIO + H₂O
" (vi) CH, + 0,— CO, + H,0
xviii) C₂H₂ + O₂2 CO₂ + H₂O
(xx) Na + H₂O → NaOH + H₂
A (xxii) PbO₂ PbO + 0₂
xxiv) NH3 + CuO →→→ → N₂ + H₂O + Cu
xxvi) H₂S + Cl₂ →→→ HCI + S
xviii) H₂S + H₂SO4 → H₂O + SO₂ + S
(xxx) C + HNO3 → CO₂ + NO₂ + H₂O
2x^2-x+x^2-3x combine like terms
3x^2-4x set equal to zero and factor
x(3x-4)=0 solve each individual factor to find the solutions/roots
x=4/3, 0
Answer:
Step-by-step explanation:
v+2.5c=191.5 and c+v=103, so c=103-v, using this c in first equation gives you
v+2.5(103-v)=191.5
v+257.5-2.5v=191.5
-1.5v=-66
v=44
So 44 vegetarian wraps were sold.
Answer:
S = 3.92π
Step-by-step explanation:
The formula for area of a sector is
S = (Ф/360°)πr² where Ф is the angle of the sector in degrees, and r is the radius.
The radius is half of the diameter, so we have 5 = 5.6/2 = 2.8, and Ф = 180°
The area is
S = (180°/360°)π(2.8)²
S = (1/2)π(7.84)
S = 3.92π
