y= is the dependent quanty=the amount virtual money that a player.
x=is the indepennt quanty=number of races won.

This function represents the amount of virtual money

Answer:

Given scenario is :

The game gives each player an initial amount of $5,000 in virtual money, means this is the total money. This $5000 is fixed.

Afterwards, a player gets $500 in virtual money for each race won.

Now we have to tell the following:

The independent quantity (x) is : the number of races won

And the dependent quantity f(x) or y is : the total virtual money

Also we need to tell the function that represents the amount of virtual money a player has in terms of the number of races won is. So, the function becomes:

f(x)=500x+5000 or y=500x+5000 where x is the number of races won.

Which set is closed under subtractionWhich answer choice shows that the set of irrational numbers is not closed under addition
vovikov84 [41]

Answer:

(a) Set of rational numbers

(b) \pi + (-\pi) = 0

Step-by-step explanation:

Solving (a): Set that is closed under subtraction

The solution to this is rational numbers.

For a set of number to be closed under subtraction, the following condition must be true

a -b = c

Where

a, b, c are of the same set.

The above is only true for rational numbers.

e.g.

1 - 2 = -1

5 - 5 = 0

\frac{1}{2} - \frac{1}{4} = \frac{1}{2}

4 - 2 = 2

The operations and the result in the above samples are rational numbers.

Solving (b): Choice not close under addition[See attachment for options]

As stated in (a)

For a set of number to be closed under subtraction, the following condition must be true

a -b = c

Where

a, b, c are of the same set.

In the given options (a) to (d), only

\pi + (-\pi) = 0 is not close under addition because:

\pi is irrational while 0 is rational

<em>In other words, they belong to different set</em>

Tim and Jane both work for a company that sells boxes of breakfast cereal. the boxes of cereal cost £3.00 and the amount of cere
Alenkasestr [34]

Answer:

25%

Step-by-step explanation:

As the given situation the parameters are below:-

Cost of each box = 3 pounds

Amount of cereal in each box = 160 g

now,

160 g of cereal = 100%

and

25% of 1 box of cereal = 25% of 160 g which is

= \frac{25}{100} \times 160 g= 40 g

As per the question,  it is mention that Jane need her idea to give the equal value of amount as Tim's idea, provided

160 g of cereal costs 3 pounds

and

1 g of cereal will cost

=  \frac{3}{60}\ pounds

40 g of cereal will cost 40\times \frac{3}{160}  = \frac{3}{4}\ pounds

So, the percentage of \frac{3}{4} the pound is of 3 pounds is 3 ÷ 4 ÷ 3 × 100

= 25%

Therefore as the situation, Jane need to decline the amount by 25% for the same amount as Tim's idea.
