joaquin reached the end of the trail in 2 hours and 15 minutes. Write the amount of hours he spent on the trail as a mixed number and as an improper fraction.
Final answer:
Joaquin's time on the trail is represented as the mixed number 2 1/4 hours and the improper fraction 9/4 hours.
Explanation:
Joaquin reached the end of the trail in 2 hours and 15 minutes. To express this amount of time as a mixed number and as an improper fraction, we need to convert the 15 minutes into a fraction of an hour since 60 minutes make up an hour.
First, as a mixed number, 2 hours and 15 minutes can be written as 2 1⁄4 hours because 15 minutes is a quarter (1/4) of an hour.
Next, to express it as an improper fraction, multiply the whole number (2) by the denominator (4) and add the numerator (1) from the mixed number. This gives us 8 + 1 = 9 quarters, hence 9⁄4 hours.

Mary had some cookies.she gave 2/9 of them to matthew and ate 1/3 of them. she had 8 cookies left. how many did she have at first?
Mary originally had 18 cookies. This is determined by creating and solving a ratio based on the fractions of cookies Mary had left after giving some away and eating some.
Explanation:The subject of this question is mathematics and it involves fractions. We can think of Mary's original number of cookies as 1 whole or 100%. We're told she gave away 2/9 of them and ate 1/3 of them, which means she hasn't touched 1 - 2/9 - 1/3 of the cookies.
First, we calculate the common denominator, which is 9. So, we must convert 1/3 to 3/9. Now, we have 1 whole - 2/9 - 3/9. This addition simplifies to: 9/9 - 2/9 - 3/9 = 4/9.
The 4/9 is equal to the 8 cookies she has left over. To find the original amount of cookies, we set up the following ratio: 4/9 = 8/x. Solve this ratio for x (which represents Mary's original number of cookies) by cross multiplying: 4x = 72. Divide both sides by 4 to get: x = 18 cookies.

A farmer wants to fence in a section of land for a horse pasture. Fencing costs $29 per yard. How much will it cost to fence the pasture?
Final answer:
To find the cost of fencing a horse pasture, calculate the total length needed and multiply it by the cost per yard.
Explanation:
A farmer wants to fence in a section of land for a horse pasture. Fencing costs $29 per yard. How much will it cost to fence the pasture?
To calculate the cost of fencing the pasture, you need to determine the total length of the fencing needed in yards. Once you have the total length, you can multiply it by the cost per yard to find the total cost.
Example:
Assuming the total length of fencing needed is 100 yards.Multiply the total length by the cost per yard: 100 yards x $29 = $2900.Therefore, it will cost $2900 to fence the pasture.A number devised by six is 306. What is the number?

What triangle has 0 reflectional symmetries?
Answer:
A. right scalene triangle
A triangle with 0 reflectional symmetries is a scalene triangle. Equilateral triangles, such as those on an icosahedron, have multiple symmetries. Symmetry in different contexts, like physics and chemistry, can result in a net effect of zero.
Explanation:A triangle that has 0 reflectional symmetries is a scalene triangle, where all three sides and all three angles are of different lengths and magnitudes, respectively. An equilateral triangle, like the ones that form the faces of an icosahedron, has multiple lines of symmetry because of its equal sides and angles. On another note, in vector algebra, a null vector has all components equal to zero, which implies it has no direction or magnitude. Similarly, the molecular geometry of BF3 is described as trigonal planar and possesses symmetry, resulting in a net dipole moment of zero despite having polar B-F bonds.
In physics-related symmetry, charges or forces can cancel each other out leading to a net force of zero. For instance, if equal charges are placed at the corners of a square with a charge at the center, the net Coulomb force on the center charge will be zero due to the symmetry. Similarly, in collisions, certain angles or scenarios can result in a term becoming zero, like having a head-on collision where the incoming ball stops (v1 = 0), or the balls deflect at a 90-degree angle resulting in cos(θ1 - θ2) being zero.

A machine that fills bottles with a beverage has a fill volume whose mean is 25.01 ounces, with a standard deviation of 0.02 ounces. a case consists of 24 bottles randomly sampled from the output of the machine. find the standard deviation of the total volume of the beverage in the case.
The standard deviation of the total volume of beverage in a case of 24 bottles, each with a standard deviation of 0.02 ounces, is approximately 0.098 ounces. This is calculated by multiplying the standard deviation of one bottle by the square root of the number of bottles in the case.
Explanation:The question involves finding the standard deviation of the total volume of beverage in a case of 24 bottles, given that each bottle has a fill volume with a mean of 25.01 ounces and a standard deviation of 0.02 ounces. To calculate the standard deviation of the total volume in the case, we multiply the standard deviation of a single bottle by the square root of the number of bottles in the case. This is because the standard deviation of the sum of independent random variables (in this case, the volume of each bottle) is equal to the square root of the sum of their variances.
Step-by-step Solution:
Standard deviation of one bottle = 0.02 ounces.
Number of bottles in a case = 24.
Total standard deviation = 0.02 ounces * √24.
Calculate the square root of 24, which is approximately 4.898.
Multiply the standard deviation of one bottle by this value to get the total standard deviation of the case: 0.02 * 4.898 = 0.098 ounces (approximately).
Therefore, the standard deviation of the total volume of beverage in a case of 24 bottles is approximately 0.098 ounces.

Kiera wanted to find the approximate number of historical books at the library she works at. She used the computer to randomly take a sample of 80 books and found that 6 of them were considered historical books. There are 21,360 books at this library. What is the best estimate of the amount of historical books at this library?
A sample of 80 books was taken randomly using a computer and 6 of them were considered to be historical books.
It means probability of sample would be 6 out of 80 i.e. P = 6 over 80 = 0.075 or 7.5%.
It says there are 21,360 books in the library, so Population would be 21,360 books. We can use outputs of the sample survey to represent complete collection of books in the library.
So best estimate of total historical books in the library would be 7.5% of total population.
Best estimate = 7.5% of 21,360
Best estimate = 0.075 x 21,360
Best estimate = 1602 books.
Hence, there are approximately 1602 historical books in the entire library.

Step-by-step explanation:
herman draws a scale model of one-half of the side house based on hermans scale model,what is the actual area of the entire side of the house?
The actual area of the entire side of the house is four times the area of Herman's scale model, as Herman's model represents only one-half of the side. So, if the area of Herman's model is A, then the actual area is 4A.
To find the actual area of the entire side of the house based on Herman's scale model, we need to follow these steps:
Understand the Scale: If Herman's scale model represents one-half of the side of the house, it means the scale is 1:2. This implies that every unit on the scale model represents two units in reality.
Find the Area of Herman's Model: Let's assume the area of Herman's scale model is A. Since it represents one-half of the side of the house, the actual area of one side of the house (let's call it X) would be 2A.
Calculate the Total Area of the Side of the House: Since there are two sides to a house, we need to double the area of one side: 2 * 2A = 4A.
Finalize the Answer: Therefore, the actual area of the entire side of the house is 4 times the area of Herman's scale model.
In summary, to find the actual area, we first double the area of Herman's scale model (as it represents only one-half of the side), then multiply it by 2 again to account for both sides of the house. This gives us a total of 4 times the area of Herman's model.
Here's the complete question:
"Herman draws a scale model of one-half of the side of a house. Based on Herman's scale model, what is the actual area of the entire side of the house?"
