42% ----> 42/100 -----> 21/50

answer is 21/50

gcf  =  5xy

Ther's like 72 now or so

Chicken soup

2 + 2 x 17

2 + 34

36

answer is 36

m< A  =  (1/2) [ measure of arc DE -  measure of arc BC ]  =

(1/2)  [ 123 - 55 ]  =

(1/2) [ 68 ]  =

34°

Ok whats with the 3 hour long discussion on how many people are online?

1 meter  ≈ 3.28 ft

1 mile  = 5280 ft

So

5280 / 3.28   ≈  1610 meters

I searched "Scientific calculator" in Google.

good question

-2/7*x - 5/6 = -2/3        

Multiply through by the common denominator of  7, 6 and 3  =  42

-12x - 35  =  -28      add  35 to both sides

-12x  =  7               divide both sides by -12

x  = - 7 / 12

(4/7)n  = n + 2    multiply through by 7

4n =  7n + 14     subtract 7n from both sides

-3n   =  14         divide both sides by -3

n  =  - 14 / 3

i like that song

Extend UR through to some point P

Then....the measure of amgle PRS   = (1/2)minor arc RS   =  (1/2)(82)  = 42°

And by the exterior angle theorem, m< PRS  =  m< U + m< S....so......

42°  = m< U  + 30°     subtract 30° from each side

12°   =   m< U

hi how r u

it can posiblly be c=3 also idk how to spel derp  soo funy

Dude, just calm down. No one has to get hurt here.

2. What is the value of x?

sin(x+37)dg=cos(2x+8)dg

The sine and cosine are co-functions.....so......the sum of their angles  = 90°  .......so....

x + 37 + 2x +  8   = 90   simplify

3x + 45  = 90       subract 45 from both sides

3x   = 45    divide both sides by 3

x = 15°

3. Given cos x 12/13 and sin x 5/13, what is the ratio for tan x? Answer as a fraction in simplest form.

tan x   = sin x /  cos x     =  (5/13) / (12 / 13)    =    5 / 12

4. When two chords intersect each other inside a circle, the products of their segments are equal.

So....

7 * 4  =  5 * z     divide both sides by 5

[7 * 4 ] / 5   = z

28 / 5  =   z   =     5 + 3/5   =   5.6 

5. We can find the radius as follows :

6 / sin 120   =  radius / sin 30

6 / [  √3 / 2]   =  radius  / [ 1 / 2 ]

6 /  √3   =   radius  ≈ 3.46

And the diameter is twice this  ≈ 6.92  ≈  6.9

What?

Good luck to your team. I hope that your school will win the track meet.

Thanks

1.

sin 64º = cos xº

sin 64º = sin(90º - xº)

64º = 90º - xº

64º + xº = 90º

x = 90º - 64º

x = 26º
