(2 − 3)(1 − ) − (3 − )(3 + )
Lostsunrise [7]

Answer:

your equation is wrong!! the answer is 10

Step-by-step explanation:

the correct order of the equation is:

(2-3)(-1)-(-3)(3)

first, solve in the parentheses from left to right:

(2-3)(-1)-(-3)(3)=\\(-1)(-1)-(-3)(3)=\\1-(-3)(3)=\\

If we have 2 negative signs then we will change them to positive :

1-(-3)(3)=\\1+3(3)\\

now we have an equation with parentheses, we will multiply 3(3)\\ because the parentheses go first.

1+3(3)=\\1+9=10

An experimenter is studying the effects of temperature, pressure, and type of catalyst on yield from a certain chemical reaction
irga5000 [103]

Answer:

90

12

0.0154

Step-by-step explanation:

a) #Possible experimental run=#Temp x #pres x #cat=3x5x6=90

b) #Possible experimental run=(Temp. lowest) x 2.pres x #cat=1x2x6=12

c) C="different catalyst is used on each run"

In the first, I can choice 6 of 6 catalysts, in the second 5 of 6,...

then: P(C) = 6/6 x 5/6 x 4/6 x 3/6 x 2/6 x 1/6 = 5/324 = 0.0154

Hamburger sells 3 pounds for six dollars if Samantha 510 pounds of hamburger how much will she pay
Lina20 [59]
I believe you meant to say that if Samantha bought 510 pounds of hamburger, how much will she pay?
 
Now from the information we already have, we know that 3 pounds of hamburger will cost 6 dollars. 

The next thing we need to know is how much one pound of hamburger will cost. This will help us calculate  how much the rest will cost.

we now form an equation to assist us.
3 = 6
1= x

(where x represents the unknown price of one pound of hamburger)

Now we must cross-multiply:

3 * x = 6 x 1

3x = 6 

x = 6/3

x = 2

therefore one pound of hamburger costs 2 dollars.

Now, If one pound costs 2 dollars, how about 510 pounds?

We simply multiply:  510 x 2 = 1,020

Therefore  Samantha will pay 1, 020 dollars for 510 pounds of hamburger.

Verify the following <br> i.[ -3/4]3 = -27/64<br> ii. [-2/3]6 = 64/ 729
Juliette [100K]

Answer:

The relationships are correct and valid

Step-by-step explanation:

The correct question is as follows;

Verify the following

i.[ -3/4]^3 = -27/64

ii. [-2/3]^6 = 64/ 729

We have the solution as follows;

i) we have;

(-3/4)^3

That means ;

-3^3 = -3^3 = -27

4^3 = 64

so;

(-3/4)^3 = -27/64

ii) (-2/3)^6

(-2)^6 = 64

3^6 = 729

Thus;

(-2/3)^6 = 64/729
