Best ResponseYou've already chosen the best response.0dw:1345312296169:dw Use pythagoras theorem \(a^2+a^2=7^2\) \(2a^2=49\) Area=\(a^2\) find \(a^2\) from \(2a^2=49\)

Best ResponseYou've already chosen the best response.0So 2a=49 and then divide both sides eright?

Best ResponseYou've already chosen the best response.0divide the diagonal by \(\sqrt{2}\) to get the length of the side, then square the result

Best ResponseYou've already chosen the best response.0ok gotchu Next question. Two sqaure are similar. The ratio of a set of sides is 2:4. whatis the ratio of their area?

anonymous

Best ResponseYou've already chosen the best response.0if you call the diagonal \(d\) then the length of the side is \(\frac{d}{\sqrt{2}}\) and area is \(\frac{d^2}{2}\)

Best ResponseYou've already chosen the best response.0dw:1345313796722:dw This is what the information gives us so far. It splits our square into 2 triangles and we can do pythageoren theorem what the sides are. A^2+B^2=7^2. is the formula for the pythageroen theorem. A^2+B^2=49. We simplified this here. They are both the same thing however because the sides of a square are equal so we really have 2A^2=49. We divide both sides by 2, and get A^2=24.5 Now we have to do the opposite of squaring, and that's square root. Now we have A^2= \[\sqrt{24.5} \] This is one side of the square, and we would do \[\sqrt{24.5}*\sqrt{24.5}\] to get our area of this square

Best ResponseYou've already chosen the best response.0Lol i got the answer xD thanks man :) Next question Two sqaure are similar. The ratio of a set of sides is 2:4. whatis the ratio of their area?

Best ResponseYou've already chosen the best response.0dw:1345314609037:dw with the info. above, that's what we get and for the first square, let's find the area. Area= 2*2; Area=4. So that means for our 1st square we have an area of 4. Now we do the same for the 2nd square, we do Area= 4*4; Area=16. That means the area of both squares is 4 & 16. We put this into a ratio, and we have 4:16, which can be simplified to 1:4 if needed.

Best ResponseYou've already chosen the best response.0K. so yeah that's the square and you labelled it corretly :). We would do the same thing as we would with regular numbers, and we will multiply (2x+10)(4), and that would give us 8x+40=80. Do you know how to do the rest? :)

anonymous

Best ResponseYou've already chosen the best response.08x+40=80 40 40 8x=40 x=5<3

anonymous

Best ResponseYou've already chosen the best response.0and if you wanted to double check this problem, you would put x back into the probolv e. 5 and solve. (2(5)+10)=20, and 20*4=80 so this would be correct :)

Best ResponseYou've already chosen the best response.0K :) All you would do here, is find the area of the bigger rectangle first. 200*140=28000. Now we find the area of the pool. 30*15=450. Finally all we do is subtract them, 28000450=answer ft.^2

Best ResponseYou've already chosen the best response.0K so all we do is D1*D2/2=Area. D1=Diagonal 1 & D2= Diagonal 2

anonymous

Best ResponseYou've already chosen the best response.0K so the formula of a parallelogram is Area=Base*Height. From the info above, we got 228=b*12. Can you find the base now? :)

anonymous

Best ResponseYou've already chosen the best response.0Yep. divide 12 on both sides and get b=228/12

Best ResponseYou've already chosen the best response.0Find the missing diagonal of the rhombus that has an area of 12 feet sqaures and one diagonal of 6ft. If you may can you explain this one to me so i can understand alittle bit

anonymous

Best ResponseYou've already chosen the best response.0K. To find the area of a rhombus we do D1+D2/2=Area. The D1/2 are the diagonals. Using the info. we have we get 6+D2/2=12

anonymous

Best ResponseYou've already chosen the best response.0So do we subtract 126? and then thats the D2?

anonymous
 4 years ago
Best ResponseYou've already chosen the best response.0No, here we multiply the 2 on both sides, so we get 6+D2=24. Then we subtract both sides by 6 and get D2=18 :)

Best ResponseYou've already chosen the best response.0wait but 18 isnt an answer ..

anonymous

Best ResponseYou've already chosen the best response.0Wait whoops yeah I made a mistake sry let me see.

anonymous

Best ResponseYou've already chosen the best response.0No wait if we doublecheck what we got, in the formula D1+D2/2=12 and put 6 & 18 in, 18+6/2=12;24/2=12;12=12 it's right.

anonymous
