Question 199895: One of your tutors was kind enough to help me with this problem. I'm very new to algebra and cant get a handle on this figure and how it added up to be there can oneone assist me to have a better understanding please .0255
.046(500 - x) + .0715x = .05(500)
:
All you need now is some basic algebra
Multiply what's inside the brackets
23 - .046x + .0715x = 25
:
.046x + .0715x = 25 - 23
:
.0255x = 2
x = 2/.o255
x = 78.43 hl removed and 78.43 hl of 7.15% added
Thank you for your help

Question 204056: Find the area of the shaded portion of the circle. Use 3.14 for π. Figure not drawn to scale.
The figure is an uncircumscribed circle with a square in it that says 10cm inside the square.The shaded portion is everything outside of the square, so portions of(in) the circle. I do not know if this question can be answered without the figure, but I have tried to figure this out and I have given up, it is over my head. Or if you could just give an example of an uncircumscribed circle and the shaded portion, would be helpful also. Thank you very much for your time.

Question 204158: Use Euler's formula to answer the question.
A polyhedron has 15 vertices and 31 edges. How many faces does it have?
(I know that the formula is v+f=E+2, would I just subtract 33 from 15 to get the correct number of faces?)
Thank you so much for your help on this problem...

Question 205504: My niece is being home-schooled (8th grade) and has gotten into some algebra and geometry problems that she is clueless with. The lessons give few examples and then when you finally get used to doing that particular set of problems they throw another monkey wrench in there, just to mess with you. I have been trying to help her, as I am the only one who has taken any of this stuff, but it has been 18 years since I have seen geometry and algebra, so need a crash course. Some of it is coming back fine, but I have hit a brick wall on 2 problems. These are pretty much identical (same idea just different numbers) so if I can have one explained, maybe it will make sense and I can explain it to her. I am trying to do this step-by-step and letting her solve for herself and just checking her answers, so please keep this in mind. She is smart and grasps relatively easily, but I am not a teacher, so I need the easiest concept to be able to get this across. Thanks in advance for your time!
The problem is: Enter the dimensions of a particular rectangle that has the volume of
50x cubed - 3 - 2x + 75x^
The answer should have three (3) sets of parentheses ( )x ( ) x( ) according to the "help screen" on her schoolwork.
