12lb of Apples
Every Pound is 3$
So, 12lb*3$
12*3 = 36$
Two 20$ bills is.... 20*2 = 40$
40$ - 36$ = 4$
So, she will receive $4.00 in change.

That is adjacent and huptonuse
soh cah toah
so that is cos
cos(x)=15/21
so tehrfor
cos⁻¹(15/21)=x
where cos⁻¹ means inverse not 1/cos
use your calculator to evaluate cos⁻¹(15/21) in degrees
it is about 44.4153 degres, rounded to 44 degrees
The two angles with x in them are the same. Set them equal to each other and solve for x:
4x-5 = 3x + 11
Add 5 to both sides:
4x = 3x +16
Subtract 3x from both sides:
x = 16
Now solve for the angle next to y:
4x - 5 = 4(16) -5 = 64 -5 = 59
Y + 59 make a straight line and equals 180, so subtract 59 from 180 to get y:
y = 180 - 59 = 121
Answers:
X = 16, y = 121
angle S = (Angle TR - Angle WX )/2
Replace the known angles:
34 = (93 - Angle WX) /2
Multiply both sides by 2:
68 = 93 - Angle WX
Solve for WX:
WX = 93 - 68
WX = 25
The answer is 25 (:
Multiply the diameter by PI which is 3.14 so that means the circumference would be 15.7.
