Answer:

<u>For 1 quart of orange juice:</u>

Calories =  448

Vitamin C =  387.6 mg

Carbohydrates  = 107.56 mg

Step-by-step explanation:

The following information is given about 1 CUP of orange juice:

<h2>Calories</h2><h3>112</h3><h2>Vitamin C</h2><h3>96.9 mg</h3><h2>Carbohydrates</h2><h3>26.89 mg</h3>

Now, we have to estimate the 3 values for 1 quart of orange juice. Remember, 4 cups is 1 quart, so we need to multiply each value by 4 to get the values for 1 quart.

Calories = 112 * 4 = 448

Vitamin C = 96.9 * 4 = 387.6 mg

Carbohydrates = 26.89 * 4 = 107.56 mg

I GIVE BRAINLIEST FOR EXPLANATION AND CORRECT ANSWER EXTRA POINTS 3

Answer:

x=8

Step-by-step explanation:

The best way to go about this is to use a trig identity. You have the unknown opposite the angle and the hypotenuse, so its best to use the sine identity: sin(x)=\frac{O}{H}, where O is the opposite side, and H is the hypotenuse.

Set up the equation as:sin(27)=\frac{x}{17}, and solve for X.

I got x=7.718, rounded to x=8.

If I helped, a brainliest answer would be greatly appreciated!
