Vic is standing on the ground at a point directly south of the base of the CN Tower and can see the top when looking at an angle
mel-nik [20]

Vic and Dan are 2, 897m apart.

<h3>How to determine the distance</h3>

It is important to note that the distance between Vic and Dan is the base of CN

Let's say the distance to Dan is x

The distance to Vic is y

Using cosine ratio, we have

cos α = opposite / adjacent

α = 72°

opposite = 553. 3cm

Adjacent = x

cos  72° = \frac{553. 3}{x}

Cross multiply

cos 72 × x = 553. 3

0. 3090x= 553. 3

x = \frac{553. 3}{0. 3090}

x = 1, 790. 61 m

The distance to Vic is y

Using the cosine ratio, we have

cos 60 = \frac{553. 3}{y}

Cross multiply

0. 5y = 553. 3

y = \frac{553. 3}{0. 5}

y = 1,106. 6m

To determine how far apart Vic and Dan, we use = x + y

= 1790. 61 + 1106. 6

= 2, 897. 21m

= 2, 897m

Thus, Vic and Dan are 2, 897m apart.

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.
