Answer:
2960 ft.........is the difference between -40ft and 3000ft
9514 1404 393
Answer:
x = 22.5°
Step-by-step explanation:
Angle BED ≅ angle EBC = 6x, so angle BEA = 4x. The angles FEB and BEA form a linear pair, so we have ...
4x +4x = 180°
x = 22.5° . . . . . . divide by 8
_____
BED and EBC are "alternate interior angles" with respect to transversal BE crossing parallel lines DE and AC.
-2 negative 2 is the answer
Use this simple calcula tor to find the area and perimeter of a rectangle. ... Suppose the length is a = 6 inches and the width is b = 4 inches.
Answer:
B
Step-by-step explanation:
Our equation is as follows, B(c)=1000(1+r)^3. We are being asked to manipulate the equation and have it be r equals in order to solve for an interest rate when given a balance B. To solve the equation for the variable r, we must isolate r by completing order of operations or PEMDAS backwards.
SADMEP allows us to undo subtraction, addition, and etc in the correct order. We have no subtraction or addition outside of more complex operations. So we move to multiplication or division.
We divide both sides by 1000.

We simplify the right side.

We need to now undo the exponent of 3 by using the inverse, a cube root.
![\sqrt[3]{\frac{B}{1000}} =\sqrt[3]{(1+r)^{3}}](https://tex.z-dn.net/?f=%5Csqrt%5B3%5D%7B%5Cfrac%7BB%7D%7B1000%7D%7D%20%3D%5Csqrt%5B3%5D%7B%281%2Br%29%5E%7B3%7D%7D)
We simplify the right side.
![\sqrt[3]{\frac{B}{1000}} =(1+r)](https://tex.z-dn.net/?f=%5Csqrt%5B3%5D%7B%5Cfrac%7BB%7D%7B1000%7D%7D%20%3D%281%2Br%29)
We subtract 1 to both sides to get r alone.
![-1+\sqrt[3]{\frac{B}{1000}} =r](https://tex.z-dn.net/?f=-1%2B%5Csqrt%5B3%5D%7B%5Cfrac%7BB%7D%7B1000%7D%7D%20%3Dr)
For our last step, we simplify the denominator of the root because 10*10*10=1000.
![-1+\frac{\sqrt[3]{b} }{10} =r](https://tex.z-dn.net/?f=-1%2B%5Cfrac%7B%5Csqrt%5B3%5D%7Bb%7D%20%7D%7B10%7D%20%3Dr)
This is answer choice b.
