someone help me pls:(

Answers

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.

Help ;/ 4.3 is 12.5% of what number?

Answers

Answer:

let x represent the number

12.5n/100=4.3

12.5n=4.3x100

12.5n=430

n= 430/12.5

n= 34.4

4.3 is 12.5% of 290.7
So...
X% times 4.3 equals 12.5
12.5 divided by 4.3 would give you 2.9069...
Now... it’s a percentage so multiply that by 100 and that would give you 290.69 or 290.7.

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?

Answers

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.

ANSWER: $7,960

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?

Answers

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!!! :)

The player's free-throw percentage is 80%.The player should expect to make approximately 6 to 7 free throws per game.

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.

To solve this all you have to do is multiply seven by the numerator. -3×7 = 21, so, -21/4 simplified would be -5 1/4. so D is correct.

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.

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

To make iced coffee, Sara puts her hot coffee into a refrigerator when it’s temperature is at 130 ℉ . The temperature of the coffee drops 4 ½ ℉ each hour. What is the temperature of the coffee after 5 hours?

PLEASE HELP I’M CONFUSED

Answers

To solve this all you need to do is multiply 4 1/2 x 5 and then subtract the Sun by 130°F. So 4 1/2×5 equals 22.5. 130-22.5=107.5. so the temperature of the coffee after five hours is 107.5°F.
If the coffee starts a 130 degrees and it cools if 4 1/2 degrees an hour and is in the fridge for 5 hours so 5 X 4 1/2 and that equals 22 1/2 so you would subtract 130 by 22 1/2 which would equal 107 1/2 degrees or 107.5 degrees

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.

Answers

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.

Step-by-step explanation:

hope this helps :)

No, because the average weight of the raccoons is 24.3 pounds.

Step 1) 17+19+20+21+23+27+28+28+28+32=243

Step 2)
