SashulF [63]

Answer:

B. 4√3

Step-by-step explanation:

\sin \: 60 \degree =  \frac{x}{8}  \\  \\  \therefore \:  \frac{ \sqrt{3} }{2}  = \frac{x}{8} \\  \\  \therefore \: x =  \frac{8 \times  \sqrt{3} }{2} \\  \\  \therefore \: x =  4 \times  \sqrt{3}\\  \\  \huge \purple{ \boxed{ \therefore \: x =  4 \sqrt{3} }}\\

You buy milk that contains 180 calories per 2 cups. Use a ratio table to find the number of calories in 5.5 cups.
Ludmilka [50]

Answer:

The number of calories in 5.5 cups are <u>495</u>.

Step-by-step explanation:

Given:

You buy milk that contains 180 calories per 2 cups.

Now, to find the number of calories in 5.5 cups.

Let the number of calories in 5.5 cups be x.

As, in 2 cups there are 180 calories.

2 cups is equivalent to 180 calories.

Thus, the ratio would be 2:180.

So, in 5.5 cups there are x calories.

5.5 cups is equivalent to x calories.

Thus, the ratio would be 5.5:x.

Now, we set proportion to get the number of calories in 5.5 cups:

2:180::5.5:x

\frac{2}{180} =\frac{5.5}{x}

<em>By cross multiplying we get:</em>

2x=990

<em>Dividing both sides by 2 we get:</em>

x=495.

Therefore, the number of calories in 5.5 cups are 495.
