Write the following ratios in their lowest terms: Mixing pink paint uses 3 litres of white paint and 1 litre of red. What is the ratio of white to red?

Answers

Answer 1

The simplified ratio is: 3 : 1. This means that for every 3 liters of white paint, 1 liter of red paint is used in the mixture.

To find the ratio of white paint to red paint, we need to compare the amounts of white paint and red paint used. The given information states that mixing pink paint requires 3 liters of white paint and 1 liter of red paint.

The ratio of white paint to red paint can be expressed as:

White : Red

To simplify this ratio to its lowest terms, we need to find the greatest common divisor (GCD) of the two numbers (3 and 1) and divide both numbers by it.

The GCD of 3 and 1 is 1, as there are no common factors other than 1. Therefore, we divide both numbers by 1:

3 ÷ 1 = 3

1 ÷ 1 = 1

The ratio 3 : 1 represents the proportional relationship between white paint and red paint in terms of liters. It indicates that for every 3 liters of white paint, only 1 liter of red paint is needed to achieve the desired mixture.

This ratio is already in its simplest form since the GCD of 3 and 1 is 1, and there are no further common factors to divide both numbers by.

In conclusion, the ratio of white paint to red paint in the mixture is 3 : 1.

A car dealership buys a used car for $18,790. They mark-up the car by 20%. How much are you as the buyer going to pay?

Answers

Therefore, as the buyer, you will pay $22,548 for the used car after the dealership marks it up by 20%.

To calculate the price you, as the buyer, will pay after the car dealership marks up the car by 20%, you need to add the markup amount to the original price.

Markup amount = 20% of $18,790

Markup amount = 0.20 * $18,790

Markup amount = $3,758

The markup amount is $3,758.

To determine the final price you will pay, you need to add the markup amount to the original price:

Final price = Original price + Markup amount

Final price = $18,790 + $3,758

Final price = $22,548

Janis needs 3 gallons of lemonade for a party she has 4/4 six prints and 4 cups of lemonade or ready-made how many more cups of lemonade does Janice need

Answers

Janis needs 3 gallons of lemonade for the party. She already has 4/4 six-packs and 4 cups of ready-made lemonade. The task is to determine how many more cups of lemonade Janis needs to meet the required amount.

To find the answer, we need to convert the gallons of lemonade into cups. Since 1 gallon is equal to 16 cups, 3 gallons would be equal to 3 * 16 = 48 cups.

Janis already has 4 six-packs, which means she has 4 * 6 = 24 cups of lemonade from the six-packs. Adding the 4 cups of ready-made lemonade, Janis has a total of 24 + 4 = 28 cups of lemonade.

To determine how many more cups of lemonade Janis needs, we subtract the cups she already has from the required amount. Thus, 48 - 28 = 20 more cups of lemonade are needed for the party.

Select a value to tell how each pair of angles is related.

Answers

The value to determine the relationship between each pair of angles is their sum. we can determine whether they are complementary (90 degrees), supplementary (180 degrees), or explementary (360 degrees), which helps us understand their relationship and properties.

To determine the relationship between two angles, we can consider their sum. If the sum of two angles is equal to 90 degrees, they are complementary angles. Complementary angles are pairs of angles that, when added together, result in a right angle. For example, if Angle A measures 40 degrees and Angle B measures 50 degrees, their sum is 90 degrees, so they are complementary angles.

If the sum of two angles is equal to 180 degrees, they are supplementary angles. Supplementary angles are pairs of angles that, when added together, result in a straight angle. For instance, if Angle C measures 120 degrees and Angle D measures 60 degrees, their sum is 180 degrees, so they are supplementary angles.

On the other hand, if the sum of two angles is equal to 360 degrees, they are explementary angles. Explementary angles are pairs of angles that, when added together, result in a complete revolution or a full circle. For example, if Angle E measures 120 degrees and Angle F measures 240 degrees, their sum is 360 degrees, so they are explementary angles.

By considering the sum of the angles, we can determine whether they are complementary (90 degrees), supplementary (180 degrees), or explementary (360 degrees), which helps us understand their relationship and properties.

Answers

a) The gradient of the line passing through the points (0,6) and (3,0) is -2. b) The gradient of the line perpendicular to this line is 1/2. c) The equation for the line passing through point a and perpendicular to the line ab can be determined using the point-slope form of a linear equation.

a) To find the gradient (slope) of the line passing through (0,6) and (3,0), we use the formula: gradient = (change in y) / (change in x). Substituting the coordinates, we get (-6) / (3-0) = -2.

b) The gradient of a line perpendicular to another line is the negative reciprocal of the original gradient. Therefore, the gradient of the line perpendicular to the given line is 1/2.

c) To find the equation of the line passing through point a and perpendicular to line ab, we can use the point-slope form of a linear equation: y - y1 = m(x - x1), where (x1, y1) is point a and m is the gradient of the perpendicular line.

Santos takes the train into the city five days a week for work. For one work week he kept track of how many minutes the train ride was : 48,51,48,48,50


Calculate the mean median range in the range of the train ride times for the week

Answers

The mean train ride time for the week was 49.4 minutes, with a median of 48 minutes. The range of the train ride times was 3 minutes.

The mean, median, and range of Santos' train ride times for the week were as follows:

Mean: 49.4 minutes

The mean is calculated by adding up all the values and dividing the sum by the total number of values. In this case, the sum of the train ride times (48 + 51 + 48 + 48 + 50) is 245 minutes. Dividing this sum by the total number of days (5), we get the mean of 49.4 minutes.

Median: 48 minutes

The median is the middle value in a sorted list of numbers. To find the median, we arrange the train ride times in ascending order: 48, 48, 48, 50, 51. Since there is an odd number of values, the middle value is the median. In this case, the median is 48 minutes.

Range: 3 minutes

The range is the difference between the largest and smallest values in a set. To calculate the range, we subtract the smallest value (48 minutes) from the largest value (51 minutes). In this case, the range of the train ride times for the week is 3 minutes.

In summary, the mean train ride time for the week was 49.4 minutes, with a median of 48 minutes. The range of the train ride times was 3 minutes. These metrics provide insights into the average, central tendency, and variability of Santos' train rides throughout the week.

Leo made a 69, 84, 67, and an 81 on the first four tests. What score would he have to make on the 5th test in order to make at least a B in the course? Based on your answer, is it likely that Leo will make a B? Why or why not?​

Answers

Leo would need to score at least 99 on the 5th test to achieve at least a B in the course. The likelihood of Leo making a B would depend on his individual abilities, preparation, and performance on the 5th test.

To determine what score Leo would need on the 5th test to achieve at least a B in the course, we first need to know the grading scale or criteria for the course. Different educational institutions and instructors may use different grading scales, so without that information, it is not possible to provide an exact answer.

However, assuming a common grading scale where:

A: 90-100

B: 80-89

C: 70-79

D: 60-69

F: Below 60

We can calculate the average score Leo needs to achieve a B. To find the average, we sum up the scores and divide by the total number of tests:

(69 + 84 + 67 + 81 + x) / 5 >= 80

Simplifying the equation:

301 + x >= 400

x >= 400 - 301

x >= 99

Therefore, Leo would need to score at least 99 on the 5th test to achieve at least a B in the course.

As for whether it is likely that Leo will make a B, it depends on various factors. If Leo has consistently performed well in the course and has a history of earning high scores on tests, it is possible that he can achieve a score of 99 or higher on the 5th test. However, if Leo has struggled in the course or has not performed well on previous tests, it may be challenging for him to score high enough on the 5th test to reach a B. The likelihood of Leo making a B would depend on his individual abilities, preparation, and performance on the 5th test.

Cindy has scores of 72, 82, 83 and 89 on her Biology tests. The Final Exam counts as two tests and she will receive a C in the course if her average is from 77-84. What score must she receive on her Final Exam to earn a C in Biology?

Answers

Cindy has scores of 72, 82, 83 and 89 on her Biology tests. Cindy must score between 68 and 89 on her final exam to earn a C in Biology.

Cindy's current average score in Biology is:

(72 + 82 + 83 + 89) / 4 = 81.5

Since the final exam counts as two tests, we can calculate the total number of points Cindy can earn in the course as follows:

Total points = 4 tests + 2 tests = 6 tests

To earn a C in the course, her average score must be between 77 and 84. Let's assume she needs to score x on her final exam to achieve a C. Then her total points would be:

Total points = 72 + 82 + 83 + 89 + x + x

Simplifying this equation, we get:

Total points = 326 + 2x

To earn a C, Cindy's average score must be between 77 and 84. Therefore, we can set up an inequality:

77 <= (326 + 2x) / 6 <= 84

Multiplying both sides by 6, we get:

462 <= 326 + 2x <= 504

Subtracting 326 from all sides, we get:

136 <= 2x <= 178

Dividing by 2, we get:

68 <= x <= 89

Therefore, Cindy must score between 68 and 89 on her final exam to earn a C in Biology.

The area of a rectangle is 400 square inches and its length is 4 times its width how many inches wide is the rectangle

Answers

The width of the rectangle is 10 inches, as it is calculated by finding the square root of the ratio of the area to the length.

Let's denote the width of the rectangle as "w" inches. According to the given information, the length of the rectangle is 4 times its width, so the length can be expressed as "4w" inches.

The formula for the area of a rectangle is length multiplied by width. In this case, the area is 400 square inches, so we have the equation:

Area = Length × Width

400 = (4w) × w

400 = 4w^2

To find the width, we can rearrange the equation and solve for "w":

4w^2 = 400

w^2 = 100

w = √100

w = 10

Answers

The expression (f times g)(x) represents the product of the functions f(x) and g(x). In this case, f(x) = x - 1/3 and g(x) = 3x + 1. To find the product, we substitute g(x) into f(x) and simplify the expression.

When we substitute g(x) into f(x), we get:

(f times g)(x) = f(g(x)) = f(3x + 1)

Now, substituting the expression for f(x) into f(g(x)), we have:

f(g(x)) = (3x + 1) - 1/3

Simplifying further, we combine like terms:

= 3x + 1 - 1/3

Thus, the product of f(x) and g(x), (f times g)(x), simplifies to:

How much was the phone before the discounted price?

Answers

The original price of the refurbished phone before the 35% discount was £120. If a refurbished phone is sold at a 35% discount with a final price of £78.

To find the original price of a refurbished phone before the discount of 35%, let's use the following formula:

discount = original price - discounted price

35% of the original price can be represented as 0.35 times the original price. This will result in the equation below:

0.35x = original price - 78

Where x is the original price. So, to find the value of x, we can rearrange the equation to get:

0.35x + 78 = original price

Now we substitute the given values into the equation above:

0.35x + 78 = original price

0.35x + 78 = x - 44.1 (if x represents the original price)

Let's subtract 0.35x from both sides to isolate the x variable:

78 = 0.65x

Then, let's divide both sides by 0.65 to solve for x (the original price):

The area of the Pacific Ocean is 165 million km2. If we imagine an area of 11 million km2, what is the ratio of this area to the area of the Pacific Ocean? Enter your answer as a fraction.

Answers

To find the ratio of the area of 11 million km² to the area of the Pacific Ocean (165 million km²), we can express it as a fraction:

Ratio = Area of 11 million km² / Area of the Pacific Ocean

Ratio = 11 million km² / 165 million km²

To simplify the fraction, we can divide both the numerator and the denominator by 11 million:

Ratio = (11 million km² / 11 million km²) / (165 million km² / 11 million km²)

Ratio = 1/15

Therefore, the ratio of the area of 11 million km² to the area of the Pacific Ocean is 1/15.

Kiran poured 15 cups of water into equal-sized pitchers and filled 1 1\2 pitchers. How much water was in the full pitcher? Multiplication equation: Division equation:

Answers

Step-by-step explanation:

15 cups of water fill 1 1/2 pitchers. that is 3/2 pitchers.

in one pitcher we have then 1 / 3/2 the amount of water of the 3/2 pitchers.

that means

15 × 1 / 3/2 = 15/1 × 1/1 / 3/2 = 15/1 × 2/3 = 30/3 = 10

so, in one pitcher are 10 cups of water.

Researchers measured the data speeds for a particular smartphone carrier at 50 airports. The highest speed measured was 76. 9 Mbps. The complete list of 50 data speeds has a mean of x overbar equals17. 21 Mbps and a standard deviation of sequals 32. 78 Mbps. A. What is the difference between​ carrier's highest data speed and the mean of all 50 data​ speeds? b. How many standard deviations is that​ [the difference found in part​ (a)]? c. Convert the​ carrier's highest data speed to a z score. D. If we consider data speeds that convert to z scores between minus 2 and 2 to be neither significantly low nor significantly​ high, is the​ carrier's highest data speed​ significant?

Answers

a) The difference between the carrier's highest data speed (76.9 Mbps) and the mean of all 50 data speeds (17.21 Mbps) is 59.69 Mbps.

b) To determine how many standard deviations the difference found in part (a) represents, we can use the formula: z = (x - μ) / σ, where z is the number of standard deviations, x is the data point, μ is the mean, and σ is the standard deviation. In this case, the difference of 59.69 Mbps can be divided by the standard deviation of 32.78 Mbps to find the number of standard deviations.

c) To convert the carrier's highest data speed (76.9 Mbps) to a z score, we use the formula: z = (x - μ) / σ. By substituting the values into the formula, we can calculate the z score.

d) If we consider data speeds that convert to z scores between -2 and 2 to be neither significantly low nor significantly high, we can compare the z score calculated in part (c) with this range to determine if the carrier's highest data speed is significant. If the z score falls within the range of -2 to 2, it is not considered significantly low or significantly high.

Answers


The Apostle Paul demonstrates humility in Acts 15:36-39 and 2 Timothy 4:11 through his willingness to resolve differences. In these passages, Paul's actions and attitudes reflect his humility and his desire for reconciliation and unity among believers.


In Acts 15:36-39, Paul and Barnabas had a disagreement regarding taking John Mark on a missionary journey. Barnabas wanted to bring John Mark along, but Paul did not because John Mark had previously left them on a previous journey. Despite the disagreement, Paul shows humility by accepting Barnabas' decision and allowing him to take John Mark as his companion, while Paul chooses Silas as his own companion. This act demonstrates Paul's willingness to prioritize unity and reconciliation over personal preferences.

In 2 Timothy 4:11, Paul shows humility by reconciling with John Mark. He requests Timothy to bring Mark with him because Paul considers Mark to be helpful in his ministry. This shows a change in Paul's attitude towards Mark, indicating that he was willing to put aside any past differences and extend forgiveness and acceptance. Paul's willingness to reconcile and work alongside Mark reveals his humility and his understanding of the importance of resolving differences for the sake of the Gospel and the unity of believers.

Overall, both passages highlight Paul's humility through his willingness to resolve differences and prioritize unity, showcasing his desire for reconciliation and harmony among fellow believers.
