Hope I understood the problem correctly, but here's an idea: You could split it into three different triangles and solve each one using the pythagorean theorem (a^2 + b^2 = c^2) to find the perimeter of the entire fire. Then once the entire perimeter is found, divide the fire line length by the total fire perimeter and multiply that answer by 100. This should give you the percentage of the fire contained.

HELP!!!

Hello!

To find the circumference of a circle, use the formula: C = 2πr. Since the radius is given, we can substitute that into the formula.

C = 2(36)π

C = 72π

Therefore, the circumference of the circle is 72π inches.

I dont understand can someone help?

First you need to find area of square which is side x side which is 8x8 which is 64. Then you find the side of the triangle which is 14-8 which is 6 then you need to find the height of the dotted line I’m pretty sure there’s a formula but it looks like it’s 8 because it looks like a square so then the formula of a triangle is base times height divided by two so the base is 6 and height is 8 so 6x8 which is 48 and divided by two is 24 then you add the area of the triangle and the area of the square which is 64 so 64+24 which is 88 so I’m pretty sure the area is 88 then just put whatever units after :)

Original price of a cell phone is 154.99$ the discount is 20% what's the price off
Irina-Kira [14]
To get 10 % you have to divide by 10 .
so 154.99 ÷ 10 = 15.499.
that's 10% but you want 20% so you times 10% by 2.
15.499 X 2 = 30.998.
154.99 - 30.998 = 123.992.
you then need to round the answer so you get $123.99
Hope this helps!!

A string of decorative lights is 28 feet long. The first light on the string is 16 inches from the plug. If the lights on the st
lilavasa [31]
Well if there is 28 feet, that would be (12x28) 336 inches,  and 16 inches between the plug and the first light, there would be only 320 inches left for lights. therefore, if there are 4 inches between each light, we divide 320 by 4.  the answer we get is 80. there are 80 lights.
