Tell whether ratios form a propotion
1/4; 3/12
54/10; 81/15
18/24; 15/20
someone help me pls:(
Answer: Ratios form a proportion if they are equal when cross-multiplied.
1/4 and 3/12
Cross-multiply these ratios to compare them: 1/4 * 12 = 3, 3/12 * 4 = 3.
So they are equal and form a proportion.
54/10; 81/15
Cross-multiply these ratios to compare them: 54/10 * 15 = 81, 81/15 * 10 = 54.
So they are equal and form a proportion.
18/24; 15/20
Cross-multiply these ratios to compare them: 18/24 * 20 = 15, 15/20 * 24 = 18.
So they are equal and form a proportion.
Hence, all the ratios mentioned above form a proportion.

Gordon attends Brown Deer College. This year's tuition costs $15,660. Gordon has a baseball scholarship that will pay $4,500 this year. His parents have saved $3,200 that he can use for this year's tuition. Gordon will need to borrow the rest. How much money will he need to borrow in student loans this year?
Tuition = $15,660
Baseball scholarship pays = $4,500
Parents pay = $3,200
$4,500 + $3,200 = $7,700 = How much is payed so far
$15,660 - $7,700 = $7,960
$7,960 is how much money he will need to borrow in student loans this year.

A basketball player made 40 out of 50 free throws in last week's games.
a) Find the player's free-throw
percentage. (I believe it's 80%)
b) If the player averages eight free throws
per game, how many of them should she expect to make?
Answer:
a) The player's free-throw percentage is 80%
b) If the player averages 8 free throws per game, she should expect to successfully make 6.4 or about 6.
Step-by-step explanation:
Make the percent (80%) a fraction, 80/100.
Since the total amount of throws she makes is 8, put 8 as the denominator (bottom of the fraction) and an x as the numerator (top of the fraction) since the amount of throws she will make is unknown.
Because 80/100 is her free throw percentage, it should be consistent with the 8 she throws each game. Due to that, the x/8 is equal to the 80/100.
With the equation 80/100 = x/8, multiply diaganolly and you should get 640/100x.
When you divide that, you get 6 40/100 or 6.4 free throws made per every 8 throws. Because you can't make 0.4 of a throw, you round therefore making it 6.
I hope this helps!!! :)
a) To find the player's free-throw percentage, divide the number of successful free throws (40) by the total number of attempted free throws (50) and multiply by 100.
Free-throw percentage = (Successful free throws / Total attempted free throws) * 100
= (40 / 50) * 100
= 0.8 * 100
= 80%
Therefore, the player's free-throw percentage is 80%.
b) If the player averages eight free throws per game, we can use the free-throw percentage to determine the expected number of successful free throws.
Expected successful free throws = (Free-throw percentage / 100) * Number of attempts
Number of attempts = 8 (since the player averages eight free throws per game)
Expected successful free throws = (80 / 100) * 8
= 0.8 * 8
= 6.4
Therefore, the player should expect to make approximately 6 to 7 free throws per game.

Answer:
D) -5 1/4
Step-by-step explanation:
In this problem there is -3/4 foot change every year and you are trying to see how much changes over 7 years. That means you are multiply the 7 by -3/4. To do that you need to change the 7 into a fraction.
7= 7/1, now you are going to mulitpy the two fractions.
This line represents the numerators: 7 times -3= -21
This line represents the denominators: 1 times 4 = 4
Now that we know our fraction is -21/4 we simplify.
The simplest form you can get is -5 1/4.
I hope this helped, let me know if you have any questions!! :)

what is the answer help im having a mental breakdown
Please please please help me
Answer:
Step-by-step explanation:
Since all the answers are 100s I assume the sizes are 10, 10 and 20.
This would mean there are 2 sides of 10x10 and 4 of 10x20
The total area would be 2*100+4*200=1000. Since that's obviously not one of the answers. We can assume it's probably 15 since it should give us a full 100 number. We know the other two are probably 10 due to their sizes and them obviously being two digits. This would mean it would be 2*100+4*150=800
Answer: 800?

In a wildlife preserve, a random sample of the population of 150 raccoons was caught and weighed. The results, given in pounds, were 17, 19, 20, 21, 23, 27, 28, 28, 28 and 32. Jean made the inference, "the average weight of the raccoon population is 25 pounds". Is this statement reasonable? Explain.
Answer:
First you add all of the results together for a sum of 243. Then, you divide that sum, 243 by 10, the number of results in total. That means the average weight of 10 random raccoons out of 150 raccoons in that wildlife preserve, is 24.3 pounds. Her statement is not reasonable because Jean stated the average weight of ALL raccoons is 25 pounds.
