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

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.

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.

Tell whether ratios form a propotion

18/24; 15/20
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.

On Monday, it snowed 30 inches in 16 hours. On Thursday, it snowed 21 inches in 6 hours. On which day did it snow at a greater rate each hour? How much more per hour?

Answers

Answer:

It snowed more on thursday because

Step-by-step explanation:

you just basically divide 30 by 16           30/16 = 1.9 (simplified)

Then you divide 21 by 6                           21/6 = 3.5

Answer/ Explanation:

It snowed more on thursday because when you divide 30 by 16 you get 1.9 inches an hour, then I divided 21 by 6 you get 3.5 inches of snow an hour. So therefore on thursday it snowed more every hour.

(I don't care if you use my words for the explanation)

The rate of snow deposition on Thursday is 1.625 inches per hour more than that on Monday.

What is the rate of change?

Rate of change is defined as the change in value with rest to the time is called rate of change.

here,

The rate of snow deposition is given as,
Rate = amount of snow/time


On Monday, it snowed 30 inches in 16 hours.
Rate = 30 / 16 = 1.875 inch per hour

On Thursday, it snowed 21 inches in 6 hours.
Rate = 21 / 6 = 3.5 inch per hour

Difference in rate = 3.5 - 1.875
                           = 1.625 inches per hour

Thus, the rate of snow deposition on Thursday is 1.625 inches per hour more than that on Monday.

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
