Best ResponseYou've already chosen the best response.1Thats a lot of material, they're all just formulas, you just need to google them. I dont understand what you're looking for?

Best ResponseYou've already chosen the best response.0No like yeah its just formulas but apparently i am doing them wrong and thats what i need help with

natnatwebb

Best ResponseYou've already chosen the best response.1Well lets start with triangles then. a triangle's formula is (b)(h)(1/2) do you understand that?

Best ResponseYou've already chosen the best response.0Well I can pull up the questions so that way you can see exactly what im talking about but like I said once i open it i have to finish it so if you think you can help I will

Best ResponseYou've already chosen the best response.0thats not really what the questions are asking..I really just want to learn from the questions asked....no offense and I know that you put it up to teach it but honestly I have been sitting here for a few hours cause i need help with my question you know? i just keep reposting this not bumping but totally reposting it....

Best ResponseYou've already chosen the best response.1Thats because its not a question, you're asking me to explain the whole entire world of finding areas. thats a lot of different situations. I need something more specific that your'e struggling with.

Best ResponseYou've already chosen the best response.0Not trying to sound rude trust me not the intention and I appreciate the help with the one you posted but I just want to get mine done cause im frustrated with them and no there as specific question but I cant give it to you without opening it and then I have to do it so if I do and you say oh idk that one and I cant answer it correctly obviously i get it wrong

natnatwebb

Best ResponseYou've already chosen the best response.1if its not a quiz then what does it matter? Its to learn it and understand it. I understand the situation yoou're in, trust me i've been there dozens of times, but i cant help if i don tknow whats wrong. So, you can open your work folder and I can try to help but I'm going to explain it to understand it, not to get it done quickly.

Best ResponseYou've already chosen the best response.0cause it still counts as a grade , thats why it matters and no I literally click a link and it takes you to the question and it gets submitted and so on and so on but I cant just go grab the question and exit and im not in a rush to finish it once its started I just want to start it I dont really care how long it takes in the process of completing it

Best ResponseYou've already chosen the best response.1this is what the equation will look like

UmmmHELP

Best ResponseYou've already chosen the best response.0Oh so add them together then divide by 2

natnatwebb

Best ResponseYou've already chosen the best response.1\[9(\frac{ 8.5+26.9 }{ 2})\]

natnatwebb

Best ResponseYou've already chosen the best response.1Whats the formula for the finding the area of a triangle?

natnatwebb

Best ResponseYou've already chosen the best response.1right so just plug in your numbers

natnatwebb

Best ResponseYou've already chosen the best response.1right, then you need to convert to decimeters

Best ResponseYou've already chosen the best response.0A trapezoid has an area of 80.75 sq. in., and its two bases are 7 and 12 inches long. Find the height of the trapezoid. a.8.5 in. b.7 in. c.8.75 in. d.9.2 in. what about this?

natnatwebb
 one year ago
Best ResponseYou've already chosen the best response.1Okay so we just use our area formula for it and rearange it. so if our formula was h(bases/2)=A and we dont know the h, we just plug all the other numbers in a solve like an albegra problem.

UmmmHELP

Best ResponseYou've already chosen the best response.0but it says 2 bases so which one do i use

natnatwebb

Best ResponseYou've already chosen the best response.1both. Remember you need to add your bases together.

Best ResponseYou've already chosen the best response.1:) okay well work it like an algebra problem, what needs to be by itself on one side of the equation?

UmmmHELP

Best ResponseYou've already chosen the best response.1I'm doing the math. by hand okay? :) we have 9.5x=80.75 now tell me whats the next step?

UmmmHELP

Best ResponseYou've already chosen the best response.0okay! subtract 9.5 from 80.75

UmmmHELP

Best ResponseYou've already chosen the best response.0For an arts and crafts project, a student cut a triangle out of a rectangular piece of paper. If the triangle has a base of 6 inches and a height of 8 inches, and the rectangle has a length of 11 inches and a width of 12 inches, what is the area of the leftover paper after the triangle is cut out? a.108 in2 b.150 in2 c.174 in2 d.24 in2 almost done

natnatwebb

Best ResponseYou've already chosen the best response.1okay well we have three equations here. The area of the rectangle, the area of the triangle and then the area of the triangle subtracted from the area of a rectangle. Understand?

Best ResponseYou've already chosen the best response.0okay we will go back to it... Find the area of the trapezoid with vertices at the given points. (0, 2), (3, 2), (5, 0), (–1, 0) a. 11 units2 b. 12 units2 c. 9 units2 d. 7 units2

Best ResponseYou've already chosen the best response.1okay, the best way to do these is to actually graph them. Use a graphing calcuator or just do a quick sketch so you can see it. Then you just could your bases and plug in your equation
