A culinary club earns $1116 from a dinner service. They sold 32 adult meals and 60 student meals. An adult meal costs twice as much as a student meal.

What is the cost of an adult meal? Please explain and show all steps! The answer is 18, but I don't get how.

Answers

Well first, 32 x 18 = 576
Second 18 divided by 2 = 9
Third 9 x 60 = 540
Fourth 540 + 576 = 1116
Fifth Cost of adult meal 18
Sixth Cost of Student meal 9

Answer:

  $18

Step-by-step explanation:

Let x represent the cost of an adult meal (the value we want to know). The cost of a student meal is half that, or x/2. The total cost of all the meals is ...

  60(x/2) +32x = 1116

  62x = 1116 . . . . . collect terms

  x = 1116/62 = 18 . . . . divide by 62

The cost of an adult meal is $18.

_____

Additional comment

You can instead use a variable for the cost of a student meal, or you can use variables for both:

  a = 2s

  32a +60s = 1116

It makes sense here to solve this by eliminating the s variable in any of several ways, since you ultimately want to know the value of 'a'.

x<2.1 is the simplified inequality.

What is an inequality?

An inequality is an inequation separated by <,>≥,≤. In Mathematics, the relationship between two values that are not equal is defined by inequalities. Inequality means not equal. Generally, if two values are not equal, we use “not equal symbol (≠)”

Given here: The inequality -4x>8.4

 multiplying by -1/4 both sides we get

4x/4 < -8.4/4

x<-2.1

               

Hence, x<2.1 is the simplified inequality.

how the flibberdoodle do you graph decimals on a coordinate graph?!!

Answers

Plotting coordinates can be a little confusing, but it doesn't have to be as long as you remember a few important details. The first number in the coordinate set tells you how far right (for a positive number) or left (for a negative number) you need to travel on the x-axis. The second number in the coordinate set tells you how far up (for a positive number) or down (for a negative number) you need to travel on the y-axis. Any set of coordinates can be represented by the variables x and y. If you picture (x, y), it will help you remember the x-coordinate comes first, so you will travel either right or left before travelling up or down.

Answer:

When graphing decimals it is good to remember that a decimal is just part of a whole number. For example, 0.5 is half of 1. Therefore, if you were to plot 0.5 you would draw a dot in between 0 and 1.

6.5 would be in between 6 and 7

7.12 would be a little bit closer to 7 but it would still be in between 7 and 8

what is
7 less than the product of 30 and a number r

Answers

Step-by-step explanation:

Take your clues from the question itself.

"5 less than," tells you that you're going to have "minus 5" AFTER something else.

"Product" always means multiplication. "Unknown number" is your variable. (Usually x or n.) So "the product of 7 and an unknown number" means "7 times x." Or just "7x."

And of course, you know what "is equal to 42" means. ;-)

Now put it all together.

I know that my "minus 5" has to go second. And I know that my "is equal to" has to go last. So the "product" part has to go first.

The product of 7 and a number minus 5 is equal to 42.

7x - 5 = 42

1) s≤$15,000      2) t<35°F

Step-by-step explanation:

For the first one, you can have 15,000 but not more. So we will use this sign:

s≤$15,000

For the second one, it cannot include 35 so we will use this sign:

<

t<35°F

t >6 t 15.000 t>46 is the answer

A figure shows a triangle drawn inside a square. The area of the triangle is 40 cm², and the area of the square is 64 cm². A point on the figure is randomly selected, and its location is recorded.

After 150 trials, the randomly selected point was in the triangle 105 times.

How does the experimental probability of a randomly selected point being in the triangle compare to the theoretical probability of the event?

The experimental probability of the event is
Choose...
and the theoretical probability of the event is
Choose...
. Therefore, the experimental probability is

the theoretical probability.

Answers

Answer:

1) 70%

2) 62.5

3) GREATER THAN

Step-by-step explanation:

I TOOK THE QUIZ TOO I KNOW ITS RIGHT

The theoretical probability is less likely than the experimental probability.

What is probability?

Probability is a number that expresses the likelihood or chance that a specific event will take place. Both proportions ranging from 0 to 1 and percentages ranging from 0% to 100% can be used to describe probabilities.

The experimental probability of a randomly selected point being in the triangle is found by dividing the number of times the point was in the triangle by the total number of trials. In this case, the experimental probability is:

Experimental probability = Number of times point was in triangle / Total number of trials

Experimental probability = 105 / 150

Experimental probability = 0.7

To find the theoretical probability, we need to divide the area of the triangle by the area of the square, since the point could be selected from anywhere in the square. In this case, the theoretical probability is:

Theoretical probability = Area of triangle / Area of square

Theoretical probability = 40 cm² / 64 cm²

Theoretical probability = 0.625

Comparing the experimental probability and the theoretical probability, we can see that:

Experimental probability = 0.7

Theoretical probability = 0.625

Therefore, the experimental probability is greater than the theoretical probability.
