At a party guests drank 2/3 of the cranberry punch and 5/6 of the orange punch, They drank the same amount of each. How many ounces of each punch might there have been at the start of the party?

Answers

Final answer:

To find the starting amounts of cranberry and orange punch, we equate 2/3 of the cranberry punch to 5/6 of the orange punch. After setting up the equation 2/3 * C = 5/6 * O, we can solve for either C or O given a specific amount for one.

Explanation:

Understanding Proportional Quantities in Punch

To determine how many ounces of cranberry and orange punch might have been at the start of the party, given that guests drank 2/3 of the cranberry punch and 5/6 of the orange punch, and that they drank the same amount of each, we can set up an equation. Let's label the amount of cranberry punch initially as C ounces and the amount of orange punch initially as O ounces. According to the problem, 2/3 of C is equal to 5/6 of O; therefore:

2/3 * C = 5/6 * O

We can find a common multiple of the denominators 3 and 6 to solve the equation. For simplicity, let's assume that the common multiple is 6. If we multiply both sides of the equation by 6 to get rid of the fractions, we have:

4 * C = 5 * O

This means that the amount of cranberry punch is always 5/4 times the amount of orange punch. For example, if there were 20 ounces of orange punch at the start (O = 20), then there would have been 5/4 * 20 = 25 ounces of cranberry punch (C).

Final answer:

The party guests drank equal amounts of 2/3 of cranberry punch and 5/6 of orange punch. By setting up an equation and choosing a common multiple of the denominators (6), we conclude that one possible starting amount for each type of punch is 18 ounces, demonstrating that whenever x is chosen, y will be equal to x.

Explanation:

The student's question involves solving a problem where two quantities are compared to find out how much of each was present initially. Since the guests drank the same amount of cranberry punch and orange punch, with the proportions being 2/3 and 5/6 respectively, we can set up an equation to solve for the initial amounts.

Let x represent the original amount of cranberry punch and y represent the original amount of orange punch. According to the question:

2/3 of cranberry punch = 5/6 of orange punch

(2/3)x = (5/6)y

To find multiple answers, we could assume a common multiple of both denominators 3 and 6, which is 6. Then, if we let x = 6 and y = 6, we have:

(2/3)×6 = 4(5/6)×6 = 5

However, these amounts are not equal. We need to find a value for x and y that, when substituted into the proportion, yields an equal amount for both types of punch. Multiply both sides of the equation by 3/2 to isolate y:

y = (3/2) × (2/3)xy = x

Now, we can select any multiple of 6 for x to represent the initial amount. If we choose multiple of 6 such as 18 ounces for x, then y would also be 18 ounces. Thus, the starting amount of both cranberry punch and orange punch could have been 18 ounces each as one of the possible answers.

the statue of liberty is 305.5 feet tall from the foundation of its pedestal to the top of its torch. Isla is building a model of the statue. the model will be one hundredth times as tall as the actual statue, how tall will the model be?

Answers

The model will be 3.055 feet

Answer: 3.055 feet

Step-by-step explanation:

Given : The statue of liberty is 305.5 feet tall from the foundation of its pedestal to the top of its torch.

Its model will be one hundredth times as tall as the actual statue.

Now , One hundredth = [tex]\dfrac{1}{100}=0.01[/tex]

According to the statement,

The height of the model will be = [tex]\dfrac{1}{100}\times\text{Height of original statue}[/tex]

[tex]=\dfrac{1}{100}\times305.5=3.055\text{ feet}[/tex]

Hence, the height of the model will be 3.055 feet.

in a science class students water a plant with the same amount of water each day for 28 consecutive days. if students use a total of 23.8 liters of water over the 28 days, how many liters of water did they use each day. how many milliliters did they use each day.

Answers

Keywords:

Water, plant, water, liters, daily, milliliters, divide

For this case we must find the amount of liters of water that students used daily, for 28 days, to water a plant, knowing that they used a total of 23.8 liters of water at the end of 28 days. For this, we must divide and the result convert it to milliliters. So:

Let "x" be the number of liters of water that students used per day:

[tex]x = \frac {23.8\ liters} {28\ days}\\x = 0.85\ liters\ per\ day.[/tex]

Thus, the students used 0.85 liters of water per day.

On the other hand, we know that: 1 liter equals 1000 milliliters. Then, by rule of three:

1 L -------------> 1000 mL

0.85L ---------->?

Where "?" represents the amount of daily water watered in milliliters

[tex]? = \frac {0.85 * 1000} {1}\\? = 850\ mL[/tex]

Thus, the students used 850 milliliters of water per day.

Answer:

850 milliliters of water per day.

They use 0.85 liters = 850 mililiters each day.

Asked

The amount of water used in a day

Answer

From this we can make a comparison:

[tex]28~days=23.8~liters[/tex]

[tex]1~day=x~liter[/tex]

[tex]\displaystyle \frac{1~day}{28~day} =\frac{x~liters}{23.8}[/tex]

Tabitha was shooting free throws in gym class. She completed 6 of the shots, which was a third of 5 more than Joan completed. How many shots did Joan complete?

Answers

Final answer:

Joan completed 13 free throws. This was determined by solving the equation derived from the information that Tabitha's 6 completed shots were a third of 5 more than Joan's completed shots.

Explanation:

Tabitha completed 6 free throws, which is stated to be a third of 5 more than Joan completed. This means that if J represents the number of shots Joan completed, then 6 is one-third of J plus 5. Therefore, we can express this relationship in an equation: 6 = (J + 5) / 3.

To find out how many shots Joan completed, we solve for J as follows:

Multiply both sides of the equation by 3 to eliminate the fraction: 18 = J + 5.

Subtract 5 from both sides to solve for J: J = 18 - 5.

Calculate the result: J = 13.

Hence, Joan completed 13 free throws.

Draw a line through each point using the given slope. What do you notice about the two lines? Slope = 1/2
Number 3 please

Answers

I believe what it is asking is that you draw a line through one point using the given slope. Then you do the same for the second.

If you did this right you should notice that the lines are parallel die to the fact that they have the same slope.
Final answer:

When you draw a line through each point with a slope of 1/2, the two lines you create will be parallel to each other because they both have the same slope and increase at the same rate.

Explanation:

In mathematics, a slope of 1/2 means that for every 2 units you move to the right (horizontally), you will move up 1 unit (vertically). When you draw a line through each point using this slope, you'll notice that the two lines will be parallel to each other. That's because they both have the same slope, which means they're increasing at the same rate. Therefore, they never intersect and remain an equal distance apart from each other at all points.

Hope this helped it probbaly didnt just have a nice day

Final answer:

The percent error in Clara's estimate of the hiking trail length is calculated using the difference between actual and estimated lengths, resulting in an 8.0% error. Option B is correct.

Explanation:

To calculate the percent error in Clara's estimate of the hiking trail's length, we use the formula: percent error = (|Actual length - Estimated length| / Actual length) × 100. Clara estimated the length to be 5.75 km, while the actual length is 6.25 km.

First, calculate the absolute difference between the actual and estimated lengths: |6.25 km - 5.75 km| = 0.5 km.

Then, divide this difference by the actual length: 0.5 km / 6.25 km = 0.08.

Finally, convert this to a percentage by multiplying by 100: 0.08 × 100 = 8.0%.

Therefore, the percent error in Clara's estimate is 8.0%, making option B the correct answer.

Answers

Final answer:

The ratios 10/20 and 30/60 both simplify to 1/2, showing they form a proportion as they equal the same value when reduced to simplest form.

Explanation:

Proportion is a mathematical concept where two ratios are equivalent.

For example, the ratios 10/20 and 30/60 form a proportion.

We can show this by finding a common multiplier and simplifying the ratios.

10/20 can be simplified by dividing both the numerator and denominator by their greatest common divisor, which is 10.

This yields:

10 ÷ 10 = 1 and 20 ÷ 10 = 2. So, 10/20 simplifies to 1/2.

Similarly, 30/60 can be simplified by dividing both the numerator and denominator by 30, resulting in:

30 ÷ 30 = 1 and 60 ÷ 30 = 2. This simplifies to 1/2, the same as the first ratio.

Since both ratios simplify to 1/2, we can say that 10/20 and 30/60 form a proportion because they both equal the same value when reduced to simplest form.
