Thank you for answering, however the correct answer is 16398.

391.45 in^2. 

d. open circle + moving right from 1/2

The sum of all difference is 17,496.

1. 4*12=48

2. 16*-8=-256/2=-128

3. 4*11=44

nvm, i got it

There will be 36 line segments.

The answer is (-2) + 0 + 3 = 1.

The area of triangle QCA is 12 - 2p.

I get the same answer, so I think you're right!

Hey there!

Here you want to use tangent to solve for the angle since tan(theta)=opposite/adjacent, so:

tan(theta)=4/9

theta=tan^-1 (4/9)

theta=23.96 degrees

You want the nearest tenth, thus your answer is

x = 24.0 degrees

Hope this helped :)

Hey there.

Here we have 2 unknowns and 2 variables so you need two equations.

Let x=number of adult tickes purchased

Let y=number of student tickets purchased

we know that 1181 tickets were sold and $2845 was raised. Given that we get the two equations:

x+y=1181

5x+y=2845

Here we can use elimation by taking the first equation from the second:
 

4x=1664

x=416 adults

Now you sub this back in to get y:
 

416+y=1181

y=765 students

Thus you have 416 adult tickets and 765 student tickets

Hope this helped :)

\(x-11=7\)

Add 11 to both sides: \(x-11+11=7+11\)

Simplify: \(\boxed{x=18}\)

\(x^2+13^2=85^2\quad :\quad x=84,\:x=-84\)

Hey there!

Here we know 2 angles of the left triangle will be 75 and 45. using this, the bottom right angle will be 60

Now we can find the bottom left angle of the triangle on the right, which will be 41.

Again, since a triangle has 180 degrees alltogether, the bottom right angle of the right triangle will be 71.

Finally, using this you know that ?=180-71=109

Hope this helped :)

Good Job!

Two angles of a triangle measure 30 and 45 degrees. If the side of the triangle opposite the 30-degree angle measures 6√2 units, what is the sum of the lengths of the two remaining sides? Express your answer as a decimal to the nearest tenth.

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

∠A = 30º        ∠B = 45º         ∠C = 180 - 30 - 45 = 105º

a = 6√2

a/b = sin∠A / sin∠B             b = 6√2 * sin45º / sin30º         b = 12

a/c = sin∠A / sin∠C             c = 6√2 * sin105º / sin 30º       c ≈ 16.4

b + c ≈ 28.4          (This answer is ≈ correct)

Pleeeeease, don't post this question again. 

thanks

What is x-11=7?  Just a fun question to ask :D     

The expression  x – 11 = 7  is called an equation.  It's a simple equation.  In this instance it means that x is equal to 18.  

_.

12 days is   3 half lives

2 ---------  4 ---------   8  --------  16  mg initially

5 weeks =  5 x 7 = 35 days             35 days / 4days/half life = 8.75 half lifes

16 mg (1/2)^8.75   = .03716 mg

2*c = 2 * 12

o = 16

4 *h = 4*1 = 4

24 + 16 + 4 = 44                  molecular weight   176        176/44 =  4     so there is   4  empirical in the molecular
