Like containing a fire?
then use anything to cut out the oxygen (like a bucket or a spoon if it’s a tiny flame)

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.

Solve for x. 3x ^2 -4 = 8

LenKa [72]

Answer:

x = ±2

Step-by-step explanation:

3x ^2 -4 = 8

Add 4 to each side

3x ^2 -4+4 = 8+4

3x^2 =12

Divide each side by 3

3x^2 =12

3x^2/3 = 12/3

x^2 = 4

Take the square root of each side

sqrt(x^2) = ±sqrt(4)

x = ±2

Firlakuza [10]

Part 1) Find the measures of angle BGE
we know that
The inscribed angle measures half of the arc it comprises.
so
angle BGE=(1/2)*[arc EB]

Part 2) Find the angle BDG
we know that
The measure of the external angle is the semi-difference of the arcs that it covers.
so
angle BDG=(1/2)*[arc GEB-arc GB]

THIS IS 8TH GRADE MATH (Pre-Algebra).

gtnhenbr [62]

First you need to set up a formula. Underline all of your givens:

Spent 1/2 on clothes
$6 more for washing windows
Ended with $10.

now you need to set up an equation.

You know she ended up with $10. So that will be what it equals. Then you know that she earned $6 in addition to her allowance. So this would be (x= allowance) (x+6)/2 = 10.

Now you need to solve for x.
Multiply both sides by 2.

x+6=20
Now subtract both sides by 6 to get x alone:

x=$14
