Kendra drank a 15-fluid-ounce bottle of water before tennis practice. After practice, she drank 3 cups of water. What is the total amount of water Kendra drank?

39 fluid ounces OR 4.875 cups

Step-by-step explanation:

To solve this problem, we need to find out how many fluid ounces are in one cup.

1 cup = 8 fluid ounces

3 cups = 24 fluid ounces

15 fluid ounces + 3 cups = 15 fluid ounces + 24 fluid ounces = 39 fluid ounces

OR

1 fluid ounce = 0.125 cup

15 fluid ounces = 1.875 cup

15 fluid ounces + 3 cups = 1.875 cup + 3 cups = 4.875 cups

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,
