So we can calculate the area in the entire box first which is a 5 by 5 box meaning it has an area of 25(5*5 = 25)

Then we just find the other three right triangles and just find the area of each one of them and then subtract the area from 25.

So the first right triangle is 1*5 = 5/2 = 2.5

second right triangle is 2*4 = 8 /2 = 4

the last one 5*3 = 15/2  = 7.5 

now add these areas together and get 7.5+4+2.5=14. now we do 25-14 = 11. we get 11 as our answer!

Hint: area of a triangle=(h_b*b)/2

First plug in, the numbers and then simplify.

Yes, can you figure something out from that?

I used triangles to find the ratio of the areas.

no?      

Great use mozilla in the future for images, and happy mozzerella earting!

Think about the area for a triangle.

What is the formula?

This is not the official way to do it but this is the way I did it and it is correct.

I hope I am not too late to the party!

Let ABCD be a trapezoid with bases AB and CD. Let AD=5 and BC=7, and let P be a point on side CD such that CP/PD=7/5. Let X and Y be the feet of altitudes from P to AD and BC respectively. Show that PX=PY

Please fix your latex and I will give you a hint on your writing problem.

The remainder is f(x) = -x^2 + 4x + 5.

This simplifies to \sqrt[3]{4} + 1.

Using recursion, we find that there are 5,681 ways.

Sorry that isn't correct.

An equilateral triangle with side length s is positioned with one vertex on the center of a circle with radius r. Find the quotient s/r that causes the area inside the triangle but outside the circle to be the same as the area of the circle.

If it's flagged, it means you may have put some offensive language... not that offensive, just use regular language and not rude ones, and don't put italics.

You aren't in trouble....

Hope melody has cleared your "confuzzledness"!

Pythog triples...

345...

If AD is the 4, so then we have side lengths 9, 12, 15.

Maybe?

5,12,13...

Maybe for the ADC...

In that case DC is 5... BD is 9...

but this is pure guesswork

Do you ahve any other information?

thank you!

we do 6*6/2=18 so we get 18/100=18% and it is 18% of this 100-square grid

you mean Mozilla Firefox Oh yeah I have that I even have Filezilla

I have seen questions like this beore so here are a coupple hints and steps!!!

1. Start by labeling your diagram with the information already known.

2. After that  can you use similar triangles and ratios of the different numbers?? Just a thought

I dont really know what they mean science but try those 2 hints and see if you can figure out an explnation just explaning those steps!

If you need more help please ask agian.
