Answer:
D.x = 6; m∠XOY = 18°
Step-by-step explanation:
Supplementary angles add to 180 and complementary angles add to 90
∠WOZ + ∠WOX = 180
108 + ∠WOX = 180
∠WOX + ∠XOY = 90
∠WOX + 3x = 90
∠WOX = 90 -3x
Replace WOX in the first equation
108 + ∠WOX = 180
108 + 90 -3x = 180
Combine like terms
198 -3x = 180
Subtract 198 from each side
-3x = 180-198
-3x = -18
Divide by -3
-3x/-3 = -18/-3
x = 6
∠XOY = 3x = 3*6 = 18
Answer:
Volume of round cake pan = volume of cylinder
Volume of a cylinder = 
(where r is the radius and h is the height)
Radius = 
diameter ⇒ 
⇒ volume of round cake pan = 
= 76.97 in³ (nearest hundredth)
Volume of rectangular cake pan = volume of rectangular prism
volume of rectangular prism = 
(where w is the width, l is the length and h is the height)
⇒ volume of rectangular cake pan = 6 x 9 x 2 = 108 in³
As 108 > 76.97, the rectangular cake pan has a larger volume
5,600
8000*.10(y)
8000*.10(3)
8000*.3
5600
She could withdraw $25 for 12 weeks and would have $200 left
Subtract 2
y-2=1/2 x
Multiply by 2 to cancel out the denominator and to get 1 in front of x
2(y-2)=x
You can stop there or you can multiply out.
2y-4=x
