The ratios of corresponding sides and corresponding angles are equal. The measurement of one side or angle in either triangle or additional information that allows us to set up proportions and solve for the unknowns.
To find the unknown measures in the similar triangles ▵XYZ ~ ▵PQR, we need to determine the corresponding sides and angles that are proportional.
Corresponding sides:
Corresponding side XY in ▵XYZ corresponds to side PQ in ▵PQR.
Corresponding side XZ in ▵XYZ corresponds to side PR in ▵PQR.
Corresponding side YZ in ▵XYZ corresponds to side QR in ▵PQR.
Corresponding angles:
Angle X in ▵XYZ corresponds to angle P in ▵PQR.
Angle Y in ▵XYZ corresponds to angle Q in ▵PQR.
Angle Z in ▵XYZ corresponds to angle R in ▵PQR.
Based on the similarity of the triangles, we can set up proportions using the corresponding sides or angles. Let's denote the measures of the corresponding sides as follows:
XY = x, PQ = y
XZ = a, PR = b
YZ = c, QR = d
Using the corresponding side lengths, we can write the following proportions:
XY / PQ = XZ / PR = YZ / QR
Substituting the values, we have:
x / y = a / b = c / d
Similarly, using the corresponding angles, we can write the following proportions:
Angle X / Angle P = Angle Y / Angle Q = Angle Z / Angle R
Now, without specific measurements or additional information about the triangle, we cannot determine the exact values of the unknown measures in ▵XYZ and ▵PQR. However, based on the given similarity, we know that the ratios of corresponding sides and corresponding angles are equal.
Therefore, to find the unknown measures, we need either the measurement of one side or angle in either triangle or additional information that allows us to set up proportions and solve for the unknowns.

Emily can walk 3/4 of a mile in 1/4 of an hour. At the same rate, time taken to walk 1 mile =1/3 of an hour.
Mathematical representation
We know that, Emily can walk 3/4 of a mile in 1/4 of an hour.
Meaning,
Time taken to walk 3/4 of a mile = 1/4 of an hour
Distance covered = 3/4 mile
We need to find the time taken by Emily to walk 1 mile.
The rate is defined as the distance covered in unit time. So,
Rate = Distance / Time
We know that Rate of Emily = 3/4 ÷ 1/4

Maija is building a square sandbox with sides 2 feet long. She wants to put sand 1.55 feet deep in the box. How much sand should Maija order?
To calculate the amount of sand Maija should order, we need to find the volume of the sandbox. The sandbox is in the shape of a cube, so its volume is determined by multiplying the length, width, and height.
Given that the sides of the square sandbox are 2 feet long and the desired depth of the sand is 1.55 feet, we can calculate the volume as follows:
[tex]\[ \text{Volume} = \text{Length} \times \text{Width} \times \text{Height} \][/tex]
Since all sides of the sandbox are equal in length (2 feet), the formula simplifies to:
[tex]\[ \text{Volume} = \text{Side}^3 \][/tex]
Substituting the values:
[tex]\[ \text{Volume} = 2 \, \text{ft} \times 2 \, \text{ft} \times 1.55 \, \text{ft} \][/tex]
[tex]\[ \text{Volume} = 6.2 \, \text{cubic feet} \][/tex]
Therefore, Maija should order 6.2 cubic feet of sand for her sandbox.

We often read that iq scores for large population are centered at 100.What percent of these 78 students have scores above 100?
It is not possible to determine the percentage of students with scores above 100 without additional information, such as the mean and standard deviation of the IQ scores of the population.
To determine the percentage of students with scores above 100, we need to know the mean and standard deviation of the IQ scores of the population. IQ scores are standardized such that the average score is set to 100, with a standard deviation of 15. However, without information about the distribution of the scores, it is not possible to provide an accurate percentage.
Assuming the distribution of IQ scores follows a normal distribution, we can use a table or a statistical calculator to estimate the percentage. For example, if we know the mean and standard deviation of the IQ scores, we can calculate the z-score for an IQ score of 100. The z-score measures the number of standard deviations a particular score is away from the mean.
Once we have the z-score, we can consult a standard normal distribution table or use a statistical calculator to find the corresponding percentage of scores above the given z-score. This percentage represents the proportion of students with IQ scores above 100.

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
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.

The area of a rectangle is 400 square inches and its length is 4 times its width how many inches wide is the rectangle
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
Therefore, the width of the rectangle is 10 inches. This means that the length of the rectangle is 4 times the width, which is 40 inches.

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.

To convert 1 gallon to liters, we multiply by the conversion factor of 3.79 L/gal.
1 gal. * 3.79 L/gal = 3.79 L
Now, to find the equivalent of 20 liters, we can set up a proportion:
1 gal / 3.79 L = x gal / 20 L
Cross-multiplying and solving for x, we get:
x = (1 gal / 3.79 L) * 20 L = 20 / 3.79 gal
Rounding to the nearest tenth, we have:
x ≈ 5.3
Therefore, the answer is d. 5.3.

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?
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.

Refurbished phone 35% off
Now only £78
How much was the phone before the discounted price?
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):
x = £120

What are the new diminsions of a 4x6 photo enlarged 2:3
Answer:
Step-by-step explanation:
To enlarge a 4x6 photo with a ratio of 2:3, we can multiply the dimensions of the photo by the enlargement ratio to find the new dimensions.
Original photo dimensions: 4 inches x 6 inches
Enlargement ratio: 2:3
To find the new dimensions, we can multiply the original dimensions by the enlargement ratio:
New width = 4 inches x 2 = 8 inches
New height = 6 inches x 3 = 18 inches
Therefore, the new dimensions of the enlarged photo would be 8 inches x 18 inches.

Brandon is running errands for his mother. It is 1 4 mile from his house to the library and 2 3 mile from the library to the grocery store. Brandon claims that he walks a total of 11 12 mile if he goes from his house to the library to the grocery store. Which of the following shows whether Brandon is correct and why? A. Yes; the correct distance is 11 12 mile, because 1 4 2 3 = 3 12 8 12 = 11 12. B. No; the correct distance is 10 12 mile, because 1 4 2 3 = 4 12 6 12 = 10 12. C. No; the correct distance is 1 mile, because 1 4 2 3 = 4 12 8 12 = 12 12 = 1. D. No; the correct distance is 1 1 12 miles, because 1 4 2 3 = 4 12 9 12 = 13 12 = 1 1 12.
The correct answer is D. No; the correct distance is 1 1/12 miles, because 1/4 + 2/3 = 4/12 + 8/12 = 12/12 = 1 1/12.
To solve this problem, we first need to convert the mixed numbers to fractions. 1 4 = 4 12 and 2 3 = 8 12. Then, we can add the fractions together. 4 12 + 8 12 = 12 12 = 1 1 12.
Therefore, Brandon is incorrect. He walks a total of 1 1/12 miles, not 11 1/2 miles.
