I already have mine too, but I finished all my work and asked if i could go play dodgeball in the gym. 

I wish i couldplay dodgeball.... I already have my PE credits

I got some people out, then a guy was just like "Yo, Hayley!!" I look, and he throws the ball straight in my face.

Did you mange to put anybody "out"  before you got put "out"  ????..........or.........were you the only one standing at the end???

Nice answer, Spawn........let me prove that it doesn't matter about the order in which we take the discount / tax

Taking the discount first and then applying the tax, we have

80 * .80  * 1.10  = $70.40

Taking the tax first and then applying the discount, we have

80 * 1.10 * . 80  = $70.40

The reason for this is that   A*B*C   = A*C* B

LOL, Spawn........!!!!!!

The answer is 69 pounds of baby liver

Could you be clear please?

This is like asking, how tall is the Christmas tree if it is Valentines day.

WOW

SUCH GOOGLE

MUCH SKILL

To find the mass of the sun, you multiply the density by the volume

In the sun's case, the density is 3109 pounds per 10.7639 feet.

The volume has been measured at 4.94405334100840254e+37 cubic feet

Multiply these together and you get 4.38499439485721481e+30 pounds or 1.989 X 10^30 kg

It's a little unclear as to what you have, but.....I'll give it a shot :

-4=4sin([360/70](x-12.5))-2      add 2 to both sides

-2  = 4 sin [(36/7)x - 450/7]     divide both sides by 4

-1/2  = sin [(36/7)x  - 450/7]

The sin  =  -1/2 at  210°  and at 330°

So  solving

(36/7)x - 450/7  = 210

36x - 450   =  1470

36x = 1920

x = [160/3]°   ≈ 53.333°......     with the 3s repeating

And solving

(36/7)x - 450/7  = 330

36x - 450 = 2310

36x  = 2760

x = [230/3]° ≈  76.666°.......  with the 6s repeating

The more general solutions......as shown by this graph......   https://www.desmos.com/calculator/gh9a73uifc .....    are

x = [160/3]°  + n*70°     where n is an integer      and

x = [230/3]° + n*70°   where n is an integer

X is a variable used throughout all of math, from the basic building blocks to the highest form. X can be subsituted for any number

Solve for x:
-4 = 4 sin((36 (x-12.5))/7)-2

4 sin((36 (x-12.5))/7)-2 = 4 sin(36/7 (x-25/2))-2:
-4 = 4 sin(36/7 (x-25/2))-2

-4 = 4 sin(36/7 (x-25/2))-2 is equivalent to 4 sin(36/7 (x-25/2))-2 = -4:
4 sin(36/7 (x-25/2))-2 = -4

Add 2 to both sides:
4 sin(36/7 (x-25/2)) = -2

Divide both sides by 4:
sin(36/7 (x-25/2)) = -1/2

Take the inverse sine of both sides:
36/7 (x-25/2) = (7 pi)/6+2 pi n_1  for  n_1  element Z
   or  36/7 (x-25/2) = (11 pi)/6+2 pi n_2  for  n_2  element Z

Multiply both sides by 7/36:
x-25/2 = (49 pi)/216+(7 pi n_1)/18  for  n_1  element Z
   or  36/7 (x-25/2) = (11 pi)/6+2 pi n_2  for  n_2  element Z

Add 25/2 to both sides:
x = 25/2+(49 pi)/216+(7 pi n_1)/18  for  n_1  element Z
   or  36/7 (x-25/2) = (11 pi)/6+2 pi n_2  for  n_2  element Z

Multiply both sides by 7/36:
x = 25/2+(49 pi)/216+(7 pi n_1)/18  for  n_1  element Z
   or  x-25/2 = (77 pi)/216+(7 pi n_2)/18  for  n_2  element Z

Add 25/2 to both sides:
Answer: | x = 1.22173 n+12.3982 and n element Z  and x = x = 1.22173 n+13.2127 and n element Z

You usually apply a tax before a discount so lets do the math

Forget the price right now

10% is the same as .1 so you can write a tax of $X amount of money by writing .1X

Lets apply that to the $80.8*88 = 70.4

Y is the tax and price

Y=1.1($80)

this is 110% of the $80

Then, you take a 20% discount

Write that as .8X, it will give you 80% of the price

.8($88) = $70.40

Let CPhill take this one

Da answer is 12 Pineapples.

d would equal 18 because you take both sides and multiply them by 30 in order to seperate 30 from d. so d= 18 

6/10 is her speed

150/10 is the entire time limit

(150/10)/(6/10)

Simplify by multiplying by 1 since 10/10=1

150/6 is the amount of times she could pronounce her name

150/6 = 25

Btw, that is really fast.

1. 22/36 can be simplified by 2=11/18

Would end up as 6 1/2

2. simplify 21/30 with 3=7/10

Would end up as 18

3. 72/120 with 12 =7/10

Would end up as 3 1/2

4. no simplifying

Just 11 1/2

5. no simplifying

Just 1 1/2

6. no simplifying

Just 1 1/2

7. just 7

8. We know 12 is 1/4th of 48, so 11 is less than 1/4th, so round down

Just 12

9. 28 is more that half of 45 but less than 2/3 so round down to .5

Just 9 1/2

10. 7 is more than 3/4ths of 9 so round up

Just 3 

When they are: SUBTRACTED, DIVIDED  and MULTIPLIED.

Easy enough

Take total price and divide by total amount of units and you get unit price

In this case 28.75/11528.75/115 = 0.25

28.75/115 = 0.25​
