Answer:
$4320
Step-by-step explanation:
12 divided by 2 is 6
720 x 6 = 4320
The answer is A.
If you factor it out it becomes
2x^2+10x-3x-15.
Simplify
2x^2+ 7x -15
A) k=55
b) 55t=w
c) It will take elizabeth seventeen minutes.
B because when you reflect over the y axis, the y value stays the same but the x value changes to the opposite of what it was before (for example, the value of x was 8 but when you reflect over the y axis, it changes to -8)
This will involve finding an arctangent.
We'll consider the woman's height as the "opposite" side of a triangle and the shadow as the "adjacent" side. The angle that the Sun makes equals the arc tangent of that angle.
tan (Sun's angle) = 71" / 36"
tan (Sun's angle) =

1.9722222222

when we determine the arc tangent of 1.9722222222, it will equal the Sun's angle.
arc tangent of 1.9722222222 = 63.113 degrees
