3x=4+13x=5x=5/32x=2* 5/32x=10/3
1 dozen = 12
144 / 12 = 12 dozen
12 dozen/ 3 = 4
They need 4 times the amount of flour:
3 1/4 x 4 = 13
They need 13 cups of flour
The a and b determine how big or small the shape of the conic section is.
<span>For the different conic sections given through the equations </span>
<span>Circle: x^2/a^2 + y^2/a^2=1 </span>
<span>Ellipse: x^2/b^2+y^2/a^2 = 1 </span>
<span>Hyperbola: x^2/a^2 - y^2/b^2 = 1 </span>
<span>When trying to isolate cos and sin from those equations to get cos^2t + sin^2 t = 1 you can determine the conic section when substituting cos t = x/a and sint = y/b into cos^2t+sin^2t square it and then refer to the conic section equations to determine the conic section. x defines the major axis and y is the minor axis. a and b provide the coordinate pairs</span>
Answer:
25 degrees
Step-by-step explanation:
85 +x-10 + 2x=180
85-10+3x=180
75+3x=180
3x=105
x=35
35-10=25
