Suppose 40 cars start at a car race. In how many ways can the top 3 cars finish the race?
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.

For every point I have
Part A Tim wants to buy three pairs of jeans. He compares the prices at a store in his neighborhood and at an online store. He finds that a pair of jeans costs $24 at the local store. If he buys online, each pair would cost $22, and he would have to pay a shipping fee of $6 per order.
Part B Look at the table that represents the local store. For each row in the table, find the ratio of the number of pairs of jeans to the cost of the jeans.
Part C Are the ratios that you calculated in part B equivalent? Based on these ratios, what can you conclude about the relationship between the number of pairs of jeans that Tim buys at the local store and the cost?
Part D Next, look at the table that represents the online store. For each row in the table, find the ratio of the number of pairs of jeans to the cost of the jeans.
Part E Are the ratios that you calculated in part D equivalent? Based on these ratios, what can you conclude about the relationship between the number of pairs of jeans that Tim buys at the online store and the cost?
Part F The local store where Tim shops charges a 7% sales tax for clothing. Complete the table by figuring the cost of the jeans after sales tax is applied. The first row has been done for you.
Part G From part F, find the ratio of the number of pairs of jeans to the cost with sales tax for each row in the table. Part H Are the ratios that you calculated in part G equivalent? Show your work to support your answer. What does this tell you about the relationship between the number of pairs of jeans and the cost with sales tax applied?
Please, I'm giving all of my points for this
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.

There are 15 cats ready for new homes at the pet store. There are 5 cages with cats in the store. If each cage has the same number of cats, how many cats are in each cage?
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.

Ron made 2/3 of a quart of hot chocolate. Each mug holds 1/3 of a quart. How many mugs will ron be able to fill ?
pretty sure its 2 mugs
Answer:
2 mugs.
Step-by-step explanation:
We have been given that Ron made [tex]\frac{2}{3}[/tex] of a quart of hot chocolate. Each mug holds [tex]\frac{1}{3}[/tex] of a quart.
To find the number of mugs that can be filled by [tex]\frac{2}{3}[/tex] quart of hot chocolate, we will divide [tex]\frac{2}{3}[/tex] by [tex]\frac{1}{3}[/tex] as:
[tex]\frac{2}{3}\div\frac{1}{3}[/tex]
Now, we will convert the division problem to multiplication problem by flipping the 2nd fraction as:
[tex]\frac{2}{3}\times\frac{3}{1}[/tex]
[tex]\frac{2\times 3}{3\times 1}[/tex]
[tex]\frac{2\times1}{1\times 1}[/tex]
[tex]2[/tex]
Therefore, Ron will be able to fill 2 mugs.

Answer:
The expression 3 + 4y – y(9 – 2y) + 5 is equivalent to 2y² -5y + 8 .
Option (B) is correct .
Step-by-step explanation:
As the expression given in the question be
= 3 + 4y – y(9 – 2y) + 5
First open the bracket
= 3 + 4y – 9y +2y² + 5
= 2y² -5y + 8
Therefore the expression 3 + 4y – y(9 – 2y) + 5 is equivalent to 2y² -5y + 8 .
Option (B) is correct .

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
