At a particular restaurant, each onion ring has 65 calories and each slider has 250 calories. A combination meal with onion ring

andre [41]

Answer:

The number of onion rings is 3 in the combination meal and the number of sliders is 2 in the combination meal.

Step-by-step explanation:

Given:

At a particular restaurant, each onion ring has 65 calories and each slider has 250 calories. A combination meal with onion rings and sliders has a total of 5 onion rings and sliders altogether and contains 695 calories.

Now, to find the number of onion rings in the combination meal and the number of sliders in the combination meal.

Let the number of onion rings in the combination meal be $x.$

And let the number of sliders in the combination meal be $y.$

So, the total number of onion rings and sliders are:

$x+y=5\\\\y=5-x\ \ \ .....(1)$

Now, the total number of calories each onion rings and sliders has:

$x(65)+y(250)=695$

Substituting the value of $y$ from equation (1) we get:

$x(65)+(5-x)(250)=695\\\\65x+1250-250x=695\\\\1250-185x=695$

Subtracting both sides by 1250 we get:

$-185x=-555$

Dividing both sides by -185 we get:

$x=3.$

The number of onion rings in the combination meal = 3.

Now, substituting the value of $x$ in equation (1) we get:

$y=5-x\\\\y=5-3\\\\y=2.$

The number of sliders in the combination meal = 2.

Hence, the number of onion rings is 3 in the combination meal and the number of sliders is 2 in the combination meal.

Which of the following of ordered pairs represent a function?

Julli [10]

A represents a function because each of the input values {-5, -2, 2, 5} has one and only one output (y-) value associated with it.

The same could be said of B: Each of the four input values {4, 3, 9, 11} has one and only one output (y-) value associated with it.

Thus, in both cases the given relations are also functions.

Answer:

b, d, c, a, e

Step-by-step explanation:

A formula should always come with a definition of the variables it uses. Here, you're supposed to somehow magically figure out what the variables are.

A = P(1 +r/n)^(nt)

A is the amount of the investment of principal P after t years, compounding annual rate r n times per year.

Then your blanks get filled like this:

1. A -- b the value

2. P -- d the principal

3. r -- c the annual interest rate

4. n -- a number of times compounded per year

5. t -- e number of years
