Step-by-step explanation:
Rate of growing of weed mile-a-minute = 2 ft per day
To find:
Rate of growth of weed in inches per hour ?
Solution:
First of all, let us have a look at the following units conversion:
1 ft contains 12 inches
and 1 day is equal to 24 hours.
Rate of growth of weed is Length divided by number of days.
2 ft per day means Length of 2ft divided by 1 day.
i.e.
\(\dfrac{2\ ft}{1\ day}\)
Let us put the units for conversion as discussed above:
\(\dfrac{2\times 12\ inches}{24\ hours}\\\Rightarrow \dfrac{24\ inch}{24\ hours}\\\Rightarrow \bold{1\ inches/hr}\)
So, the answer is: 1 inch/hour

A set of data contains five values. The smallest value is 0 and the range is 10
If the smallest value is 0 and the range is 10, then the largest value can be found by adding the smallest value to the range:
Largest value = smallest value + range
Largest value = 0 + 10
Largest value = 10
Therefore, the largest value in the data set is 10.
In statistics, the range is a measure of dispersion that represents the difference between the maximum and minimum values in a dataset. It is a simple and easy-to-understand way to describe the spread or variability of the data.
To calculate the range, you subtract the smallest value in the dataset from the largest value.

Carlos and Aisha take the same bike route home from school each day. Aisha lives 3 miles from school and Carlos lives 1 mile further along the path. Sometimes Aisha bikes all the way to Carlos' place before going home. Write an absolute value equation that represents how far Aisha bikes after school each day.
Answer:
|x - 4|
Step-by-Step explanation:
Let's say that the distance that Aisha bikes after school each day is represented by the variable "x". We want to write an absolute value equation that represents the distance that Aisha bikes, given that Carlos lives 1 mile further along the path.
If Aisha bikes directly home, then the distance she bikes is just the distance from school to her home, which is 3 miles. If she bikes all the way to Carlos' place before going home, then the distance she bikes is the total distance from school to Carlos' place and then from Carlos' place to her home. This total distance is equal to:
|x - (3 + 1)|
where "x - (3 + 1)" represents the distance from school to Carlos' place (which is equal to the distance that Aisha bikes beyond her home), and the absolute value symbols ensure that the expression inside the absolute value is positive.
Therefore, the absolute value equation that represents the distance that Aisha bikes after school each day is:
|x - 4|

Calculate minimum and maximum frequency for acoustic
and optic mode.
( short question (
The specific range depends on the material properties and the energy levels involved.
The minimum and maximum frequencies for the acoustic and optic modes depend on the specific system or material under consideration. However, I can provide some general information.
Acoustic Mode:
The acoustic mode refers to the propagation of sound waves or vibrations in a material. In a solid, the acoustic mode can have different types, such as longitudinal and transverse modes.
The minimum frequency for the acoustic mode is typically determined by the size and physical properties of the material. In general, it can be close to zero for macroscopic objects or materials with low elasticity.
The maximum frequency for the acoustic mode depends on factors such as the speed of sound in the material and the characteristic dimensions of the system. It can range from a few kilohertz to several gigahertz.
Optic Mode:
The optic mode is related to the interaction of light with a material. It typically refers to the vibrations of charged particles (such as electrons) in a solid or the oscillations of electric or magnetic fields associated with photons.
The minimum frequency for the optic mode is typically determined by the energy gap between electronic states in the material. For example, in a semiconductor, the minimum frequency is usually in the infrared range.
The maximum frequency for the optic mode is not strictly defined, as it can extend into the terahertz, infrared, visible, ultraviolet, X-ray, and even gamma-ray regions. The specific range depends on the material properties and the energy levels involved.
It's important to note that these frequency ranges are general guidelines and can vary depending on the specific system or material being studied.

We have;
T + N = 10
1 + A + U = 10
1 + S + S = 7
Therefore, S = (7 - 1)/2 = 3
S = 3
A + U = 10 - 1 = 9
A + U = 9
Therefore, A = 4 or 5 (2 choices)
From T + N = 10
T = 1, 2, 8, or 9 (4 choices) similarly, N = 1, 2, 8, or 9 (4 choices)
Therefore, the number of numeric values that SAT represent is given as follows;
(S = 1 choice) × (A = 2 choices) × (T = 4 choices) = 1 × 2 × 4 = 8 numeric values

The distribution of the number of occurrences of the letter t on the pages of a book is found to be a normal distribution with a mean of 44 and a standard deviation of 18. If there are 500 pages in the book, which sentence most closely summarizes the data?
Answer:
The letter t occurs more than 26 times on approximately 420 of these pages.
Step-by-step explanation:
1 standard deviation below mean = M - SD
= 44 - 18 = 26
This implies that that "26" is 1 s.d. below the mean, which is at the 16th percentile.
Thus, there is a 0.16 chance that "t" will occur less than 26 times on any single page.
consequently, there is a 0.84 chance that it will occur more than 26 times on any single page.

why couldn't Pythagoras use the pythagorean theorem as we know it?
Pythagoras was an ancient Greek mathematician who founded the Pythagorean school of thought. The Pythagorean theorem is a fundamental concept in mathematics that is attributed to Pythagoras and his followers.
It states that in a right-angled triangle, the square of the length of the hypotenuse is equal to the sum of the squares of the other two sides. While this theorem is considered a cornerstone of mathematics today, it is important to understand that Pythagoras did not have access to the advanced mathematical tools and methods that we have today.
He had to rely on geometric constructions and reasoning to prove his theorem. Furthermore, Pythagoras believed that all numbers could be expressed as ratios of whole numbers, which is not always true in reality. Despite these limitations, the Pythagorean theorem has stood the test of time and continues to be a crucial tool in mathematics and other fields.
