A recipe uses 4 cups of milk to make 12 servings. If the same amount of milk is used for each serving, how many servings can be made from three gallons?  
 
Before you try that problem, answer the question below.

How many cups will you need to find the number of servings for?

144

Step-by-step explanation:

I start by multiplying 16 (the number of cups in a gallon) by 3. This gives us 48. Then, I divide it by 4 to find how many batches of the recipe can be made, giving us 12. Afterwards, because we know that every batch makes 12 servings, I multiply 12 * 12, giving us our final total of 144.

answer:  

step-by-step explanation:

here x represents the height of the pole,

and, the height of the shadow of the pole is 12 feet.

also, the angle of elevation from the top of the pole is 40°,

therefore,

by the low of sine,

which is the required equation for finding the value of x,
