114°+x°=180
Subtract 114° for both side
x=66°. Hope it help!
<span>The first part of the quadratic formula, x = - b/2a, is the equation of the axis of symmetry, and the x-coordinate of the vertex. </span>
<span>In standard form: - 2x² + 8x - 5 = 0, a = - 2, b = 8, c = - 5 </span>
<span>The axis of symmetry: x = - 8/2(- 2) = - 8/- 4 = 2 </span>
<span>Go back and solve for y to find the y-coordinate of the vertex. </span>
<span>y = - 2(2)² + 8(2) - 5 </span>
<span>y = - 2(4) + 16 - 5 </span>
<span>y = - 8 + 16 - 5 </span>
<span>y = 3 </span>
<span>Vertex is (2, 3)</span>
Answer:
T=3
Step-by-step explanation:
4-T = 3(t-1) -5
4-t=3T -3-5
^^ distribute
-T=3T-12
^^combine like terms and subtraction prop. of equality.
-4T=-12
^^ subtraction property of equality
(-4T=12)/-4
^^ thats just getting rid of the -sign, then its also simpliying
T=3
Total food produces => 3.9 billion
total consumed = 2.6 billion
remaining = 1.3billion tons .
therefore %ve of food wasted = 1.3/3.9×100 = 33.33%
hence 33.33% food waste every year .
option b) is right answer .
