andrew11 [14]

The relationship between the two variables is inverse proportionality, that is, the greater the number of people, the less the amount of money earned.

Since visitors to a carnival are invited to guess the number of beans in a jar, and the person who guesses the correct number wins $ 300, but if multiple people guess correctly, the prize will be divided evenly among them, to determine what is the relationship between the number of people who guess correctly and the amount of money each person will recieve the following logical reasoning must be performed:

Since the prize is a fixed number, 300, it is a value that will not change. In turn, the more people who have guessed right, the lower the amount of money that each of them will win (because the number 300 will be divided by a greater number).

Therefore, the relationship between the two variables is inverse proportionality, that is, the greater the number of people, the less the amount of money earned.

A bedroom has a length of x+ 3 feet and a width of x-1 feet. Write a polynomial to express the area of the bedroom. Then calcula
jekas [21]

Answer:

Step-by-step explanation:

Length = x+3

Width = x-1

Area = l*b

where l is the length of the bedroom

and b is the breadth or width of the bedroom

The polynomial can be written as:

Area=(x+3)(x-1)

Now we will find the area of the room when x=10

First we will find the values of length and width.

Length = x+3

Length = 10+3 = 13

Width = x-1

Width = 10-1=9

Now put the values in the formula:

Area=l*b

Area=13*9

Area = 117 square feet....

I need help with dividing fractions
iVinArrow [24]

When you divide fractions, you want to use keep change flip.

You keep the 1st fraction, change the division sign into a multiplication sign, then flip the last fraction.

Let’s use 3/4 ÷ 2/3

Keep 3/4 the same, change the division sign into a multiplication sign, and flip 2/3 so that it is 3/2

It’ll look like this

3/4 x 3/2

Now just multiply the numerators, 2 x 3, then multiply the demoninators, 4 x 2.

You get 6/8

Simplify this number and you get 3/4.

If you have any further questions feel free to ask.

Hope this helps.
