The calorie density d, in calories per ounce, of a food that contains c calories and weighs w ounces is given by the formula d=c/w. ten ounces of a particular beverage contains 195 calories. find the calorie density of the beverage.

19.5 calories per ounce.

Step-by-step explanation:

Given : The calorie density D, in calories per ounce, of a food that contains c calories and weighs w ounces is given by the formula :

Also,  Ten ounces of a particular beverage contains 195 calories.

Then put w=10 and c = 195 in the above equation, we get

Hence, the calorie density of the beverage = 19.5 calories per ounce.

what graph

step-by-step explanation:

the answer is:

the correct option:

b.

to solve the problem, we need to remember how to operate to simplify exponential expressions using the logarithms.

we are given the equation:

then, using placing logarith with base 7 on both sides of the equation, we have:

so, rounding the obtained result to two decimal places (nearest hundreth), we have:

hence, we have that the correct option:

b.

have a nice day!
