The fraction that x represents would be; 3/10

A fraction represents a part of a number or any number of equal parts. When the numerator is less than the denominator, the fraction is called proper fraction, otherwise it is called improper fraction.

There is a fraction, which contains numerator(upper value) and denominator(lower value).

WE have shown the x variable on the number line.

The total points on the number line from 0 to 1 is 8.

According to this number line.

the line is divided into 10 interval, Hence fraction that the expression represent as;

Fraction =  0.1. + 0.1 + 0.1

Fraction = 1/10 + 1/10 + 1/10

Fraction = 3/10

Hence the fraction that x represents is; 3/10

Therefore, the value of x would be;

x = 3/10

Hello Athena...

Any of the 40 cars can finish first

Any of the 39 cars can finish second

Any of the 38 cars can finish third

40 x 39 x 38 = 59,280

Answer - There are 59,280 ways the top 3 cars can finish the race.

The number of ways that the top three cars can finish the race will be 59280 ways.

This is a question relating to permutations and combinations. Based on the information given in the question, the calculation will be solved thus:

= 40!/(40 - 3)!

= 40!/37!

= 40 × 39 × 48

= 59280

Therefore, the number of ways that the top three cars can finish the race will be 59280 ways.

There are 3 cats in each cage. They way you get this answer is by dividing the total amount of cats (15) by the total amount of cages (5). hope this helps

We find that there are 3 cats in each cage.

To find out how many cats are in each cage, we need to divide the total number of cats by the number of cages. There are 15 cats ready for new homes and 5 cages. If each cage has the same number of cats, we perform the following calculation:

Count the total number of cats: 15 cats.

Count the total number of cages: 5 cages.

Divide the total number of cats by the number of cages: 15 cats / 5 cages = 3 cats per cage.

Therefore, there are 3 cats in each cage.

The answer is 3.88888888889

The answer is 35/9

You first would remove the parentheses

Next you see that there is a subtraction symbol and a negative symbol right beside each other. You cant have 2 negatives side by side, so you change the symbol to addition

The problem then looks like this: 5/9 + 3 1/3

To make the problem easier you change the mixed number (3 1/3) to an improper fraction which is 10/3

Because its 5/9 + 10/3 you multiply 10 and 3 and get 30, and you keep the LCD (least common denominator) which is 9

Finally you add 5 + 30 = 35 and have 9 as your denominator

35/9 or 3 8/9

add 24, 22, and 6. for the ratio see if they all match up to the prices to the number of pairs  of jeans. then just look at ur table for jeans and see which one has the greatest value. by equivalent it means are they the same as the one that is greatesst on table D and  see if any of them are equivalent to the one you chose for E. for F all you would have to do is divide the number in A by 7. then just look at ur previous tables and find ur ratio

Tim will pay the same amount whether buying locally or online, without considering sales tax. The price per jeans remains constant in both local and online stores. When sales tax is applied, the ratio of number of pairs to price changes, increasing the cost per pair.

Each part of the problem step by step:

Part A:

Tim wants to buy three pairs of jeans. He can either purchase them at a local store for $24 each or online for $22 each plus a $6 shipping fee per order.

Part B:

For the local store, the ratio of the number of pairs of jeans (3) to the cost per pair ($24) is 3/24 = 1/8.

Part C:

The ratios calculated in Part B are not equivalent. As the number of pairs of jeans increases at the local store, the cost decreases proportionally.

Part D:

For the online store, the ratio of the number of pairs of jeans (3) to the cost per pair ($22) plus the shipping fee ($6) is 3/(22+6) = 3/28.

Part E:

The ratios calculated in Part D are not equivalent either. As the number of pairs of jeans increases online, the cost per pair decreases due to the shipping fee.

Part F:

To find the cost of jeans at the local store with a 7% sales tax, multiply the cost by 1.07 (since it's an increase of 7%). The table can be filled accordingly.

Part G:

Now, calculate the ratio of the number of pairs of jeans (3) to the cost with sales tax for each row in the table.

Part H:

The ratios calculated in Part G are not equivalent. The relationship between the number of pairs of jeans and the cost with sales tax applied at the local store shows that as the number of pairs increases, the cost with tax also increases proportionally.

The domain of the graph is {-3, -1, 1, 4}. The range of the graph is {-4, -1, 1, 4}

The domain of the set of ordered pairs is {-4, -3, 1}. The range of the set of ordered pairs is {1, 3, 4}

====================================================

Recall that the domain is the set of allowed x values. All we do is list the unique x coordinates of each point which are -3, -1, 1 and 4. The range is the set of y values so we just list the unique y coordinates of each point which are -4, -1, 1 and 4.

The same will happen with the other problem as well. The set of points listed is pretty much identical to the first problem, but the points haven't been graphed, but instead their coordinates have been listed out. The first coordinate is the x coordinate. The second coordinate is the y coordinate. Each point is in the form (x,y).

Solve for x by simplifying both sides of the equation, then isolating the variable.

x = 5

To solve the equation 5(2x-1)/3 - 4 = 11 for x, you need to isolate the term containing x on one side and perform basic algebraic operations to find that x = 5.

The mathematical equation in question is 5(2x-1)/3 - 4 = 11, which you can solve to find the value of x. First off, you should isolate the term including x on one side to simplify the equation. Multiply both sides by 3 to get rid of the division by 3. The equation then becomes: 5(2x-1) - 4*3 = 11*3, which simplifies to 5(2x-1) - 12 = 33. Then, add 12 to both sides to isolate the term containing x on one side: 5(2x-1) = 45. Next, divide both side by 5 so the equation becomes: 2x-1 = 9. Finally, add 1 then divide by 2 to solve for x, and you get x = 5.

let's firstly, convert the mixed fractions to improper, and then multiply.

[tex]\bf \stackrel{mixed}{3\frac{2}{5}}\implies \cfrac{3\cdot 5+2}{5}\implies \stackrel{improper}{\cfrac{17}{5}}~\hfill \stackrel{mixed}{2\frac{1}{3}}\implies \cfrac{2\cdot 3+1}{3}\implies \stackrel{improper}{\cfrac{7}{3}} \\\\[-0.35em] \rule{34em}{0.25pt}\\\\ \cfrac{17}{5}\cdot \cfrac{7}{3}\implies \cfrac{17\cdot 7}{5\cdot 3}\implies \cfrac{119}{15}\implies 7\frac{14}{15}[/tex]

This is a procedure to multiply mixed numbers. Then multiply the fractions and simplify the resulting fraction into a mixed number.

The problem asked here is a multiplication problem with mixed numbers. First, let's convert 3 2/5 and 2 1/3 to improper fractions. For 3 2/5, multiply 5 (the denominator) and 3 (the whole number), then add 2 (the numerator). We get 17/5. For 2 1/3, multiply 3 (the denominator) and 2 (the whole number), then add 1 (the numerator). We get 7/3.

Now let's multiply the fractions. The resulting fraction is (17/5) x (7/3) = 119/15. This simplifies to 7 14/15.

So, 3 2/5 multiplied by 2 1/3 equals 7 14/15.
