On Thursday, Movietown Theater made \dfrac45
Oliga [24]

Answer:

11 Pounds

Step-by-step explanation:

Let the total pounds of popcorn made by Movietown Theater=x

On Thursday, they made \dfrac{4}{5} of their popcorn with butter.

The remaining fraction of the butter will be: 1-\dfrac{4}{5} =\dfrac{1}{5}

The remaining 35.2 Ounces was made without butter.

Let us convert from ounces to pounds.

  • 1 Ounce =0.0625 Pound
  • 35.2 Ounce=35.2 X 0.0625 =2.2 Pounds

Therefore:

\dfrac{1}{5} \text{of the total pounds of popcorn} = 2.2\\\dfrac{1}{5}* x = 2.2\\x=2.2* 5\\x=11 $ Pounds

Therefore, the total pounds of popcorn made by Movietown Theater on Thursday is 11 Pounds.

How do you convert units within a measurement system
Crazy boy [7]
You have to know how the value of one unit corresponds to the value of the other unit. For example you have to know that there are 100 cm in 1 m or 1000 m in 1 km. It's easy in metric measurement system because it's all about multiplying/dividing by 10 or its multiplications. But in American/English system you just have to learn the values.

For example:

1 km = 1000 m = 10000 dm = 100000 cm = 1000000 mm

But:

1 mile = 1760 yards = 5280 feet = 63360 inches

If f(x) = x^3 – 10x^2 + 29x – 30 and f(6) = 0, then find all<br> of the zeros of f(x) algebraically.
tino4ka555 [31]
Step 1: 1

(((x3) - (2•5x2)) + 29x) - 30 = 0

Step 2 2.1 x3-10x2+29x-30 is not a perfect cube

Step 3 Factoring: x3-10x2+29x-30

Thoughtfully split the expression at hand into groups, each group having two terms :

Group 1: 29x-30
Group 2: -10x2+x3

Pull out from each group separately :

Group 1: (29x-30) • (1)
Group 2: (x-10) • (x2)
