The cost price of cloth that John bought per meter is Php 46.00 (Option C). To find the cost price per meter, divide the total cost by the number of meters of cloth.
In this case, the total cost is Php 425.50 and the number of meters is 9.25. By dividing the total cost by the number of meters, we get Php 46.00 per meter. This means that John paid Php 46.00 for every meter of cloth he bought. This is the cost price per meter and it is option C, Php 46.00.
The specific value that corresponds to the unit price that was purchased is reflected in retail systems by the cost price. In some stock market theories, this value is used to determine the value of stock holdings, and it is used as a key factor in determining profitability.

What are dimensions?The minimal number of coordinates required to specify each point within a mathematical space (or object) is known as the dimension in physics and mathematics.
Because only one coordinate is required to identify a point on a line, such as a point at 5 on a number line, a line is said to have one dimension (1D).
Because two coordinates are necessary to identify a point on a surface, such as the perimeter of a sphere or cylinder, it is referred to as having a dimension of two (2D).
For instance, a point on the surface of a sphere requires both a latitude and a longitude to be located.
So, we can use a scale of 2:5 as a conversion factor to identify the table's missing dimensions.
For instance, the model's length in the second row is 2 inches, but the real length is 5 inches.
This implies that the model's 1 inch corresponds to the actual object's 5 inches.
The actual depth is 10 5 = 50 km because the model's depth is 10 km.
Since the model's length is not specified in the fourth row, we are unable to determine its true length.
Therefore, the model on the fifth row has a diameter of 32.5 meters, hence the actual diameter is 32.55 = <<32.55=162.5>>162.5 meters.

Your family drives 126 miles from Key West to the Florida mainland about 15% of this distance is spent on bridges how many miles of the bridges do you come travel over
Answer:
Step-by-step explanation:
The 15% of 126 is 18.96 thus, my family travels 18.96 miles over the bridge.
What is the percentage?
The percentage is defined as a given amount in every hundred. It is a fraction with 100 as the denominator percentage is represented by the one symbol %.
The percentage is also called the indicating hundredths. Thus, 2% is two-hundredth, which means 2%=2/100=0.02.
As per the given,
Total travel = 126
Percentage travel over the bridges = 15% of 126
15% of 126 = (15/100)126 = 18.96 miles
Hence "The 15% of 126 is 18.96 thus, my family travels 18.96 miles over the bridge".

if a state wants each of its license plates to contain any 7 digits, how many different license plates are possible?
There are 10 million possible 7-digit license plates that a state can issue.
This is because each digit position can be filled with any of the 10 digits (0-9), giving us 10 options for each digit position.
By multiplying these 10 options for each of the 7-digit positions,
we get 10 * 10 * 10 * 10 * 10 * 10 * 10 = 10^7.
This amount is sufficient to guarantee that every citizen can have a distinctive license plate number.
It is significant to note that some restrictions, such as those that constitute a profane word or imply an official status, may prevent the issuance of particular license plate numbers.

santa clara county, ca, has approximately 27,873 japanese-americans. what percentage of the community is under age 35?
The percentage of Japanese-Americans under 35 in Santa Clara County, CA is approximately 11.3%.
Santa Clara County, CA is home to approximately 27,873 Japanese-Americans. To determine what percentage of this population is under age 35, it is necessary to first calculate the total number of Japanese-Americans under 35. To do this, we can subtract the estimated number of Japanese-Americans over age 35 from the total population of Japanese-Americans. We can then divide this number by the total population of Japanese-Americans to find the percentage of Japanese-Americans under age 35. In Santa Clara County, CA, the estimated number of Japanese-Americans over age 35 is 24,672, and the total population of Japanese-Americans is 27,873. Subtracting 24,672 from 27,873 yields 3,201 Japanese-Americans under age 35. We can then divide 3,201 by 27,873 to get a percentage of 11.3%. Therefore, approximately 11.3% of the Japanese-American population in Santa Clara County, CA is under age 35.

are square with side lengths 11
3 feet. How many tiles are needed to cover the entire
floor? Show your reasoning.
165 tiles are needed to cover the entire floor of the room.
First, we need to find out the area of the room in square feet. We do this by multiplying the length and width of the room:
12 feet x 15 feet = 180 square feet
Next, we need to find out the area of one tile in square feet. We do this by squaring the length of one side of the tile:
11 3/11 feet x 11 3/11 feet = 128/121 square feet
Now, we can divide the total area of the room by the area of one tile to find out how many tiles are needed:
180 square feet / (128/121 square feet) = 180 x 121/128 = 165 tiles
So, 165 tiles are needed to cover the entire floor of the room.

an arithmetic sequence with first term 1 and common difference not equal to 0 has second, tenth, and thirty-fourth terms that form a geometric sequence. what is the thirty-fourth term of the arithmetic sequence?
The thirty-fourth term of the arithmetic sequence is the thirty-second term plus the common difference, which is not equal to 0.
The thirty-fourth term of the arithmetic sequence is calculated by adding the common difference to the thirty-second term. The common difference is the amount by which each successive term increases or decreases. As the common difference is not equal to 0, the thirty-fourth term is not the same as the tenth or second terms. The second, tenth, and thirty-fourth terms form a geometric sequence, which means that the ratio between any two successive terms is always the same. This ratio is determined by the common difference of the arithmetic sequence, and the thirty-fourth term can be calculated by adding the common difference to the thirty-second term.

The 98% confidence interval to estimate the true cost of a gallon of milk is $2.73 to $3.23.
What do you mean by standard error?The standard error is a measure of the variability or spread of a set of sample values. In statistics, the standard error is used to quantify the precision of an estimate of a population parameter, such as the mean or standard deviation. It is calculated as the standard deviation of the sampling distribution of a statistic, usually the mean. The standard error is a useful measure because it provides a way to compare different estimates of a population parameter, and it can be used to construct confidence intervals, which provide a range of values within which the true population parameter is likely to lie with a specified degree of confidence.
The 98% confidence interval to estimate the true cost of a gallon of milk can be calculated using the following formula:
CI = (sample mean) ± (critical value) * (standard error)
Where critical value can be obtained from a standard normal distribution table, corresponding to a given level of confidence.
For 98% confidence, the critical value is 2.33.
CI = $2.98 ± 2.33 * $0.10 = $2.98 ± $0.23 = $2.73 to $3.23
Therefore, the 98% confidence interval to estimate the true cost of a gallon of milk is $2.73 to $3.23

Answer:
273/4
Step-by-step explanation:
We know
A company’s stock opened at 68 3/8 dollars per share
68 3/8 = 547/8
The stock dropped 1 7/8 dollars on Monday
1 7/8 = 15/8
547/8 - 15/8 = 532/8
The stock dropped another 2 1/2 dollars on Tuesday.
2 1/2 = 5/2
532/8 - 5/2 = 532/8 - 20/8 = 512/8
On Wednesday, the stock gained back 4 1/4 dollars.
4 1/4 = 17/4
512/8 + 17/4 = 512/8 + 34/8 = 546/8
546/8 = 273/4

A passenger train and a freight train leave cities 260 mi apart and travel toward each other. The passenger train is traveling
15 mph faster than the freight train. Find the speed of each train if they pass each other after 4 hr.
Step-by-step explanation:
x = speed of the passenger train
x - 15 = speed of the freight train
remember, the passenger train is traveling 15 mph faster than the freight train. that also means the freight train travels 15 mph slower than the passenger train.
we could define the variable also the other way around (x = freight train, x + 15 = passenger train).
speed = distance/time period
distance = speed × time period
so,
x×4 + (x - 15)×4 = 260
because when both trains meet somewhere in the middle, it means that the sum of both of their ways traveled is the whole distance between both cities : 260 miles.
4x + 4x - 60 = 260
8x = 320
x = 320/8 = 40 mph
so, the passenger train traveled at 40 mph.
the freight train traveled at 40-15 = 25 mph.

5i + 4 = 14 + 4i thanks yall
Answer:
The solution to the equation 5i + 4 = 14 + 4i is i = 10.
Step-by-step explanation:
To solve for i in this equation, isolate the variable (i) on one side of the equation. To do this, we'll subtract 4 from both sides:
5i + 4 - 4 = 14 + 4i - 4
This leaves us with:
5i = 10 + 4i
Next, we'll subtract 4i from both sides:
5i - 4i = 10 + 4i - 4i
This leaves us with:
i = 10.
So the solution to the equation 5i + 4 = 14 + 4i is i = 10.

How to find the probabilityA quiz consists of 10 multiple-choice questions, each with 6 possible answers. for someone who makes random guesses for all of the answers, find the probability of passing if the minimum passing grade is 50 %.
The probability of a random guess being correct for a single multiple-choice question with 6 options is 1/6, or approximately 0.17.
To find the probability of passing the quiz with a minimum passing grade of 50%, we need to calculate the probability of getting 5 or more correct answers out of 10.
This can be calculated as the sum of the probabilities of getting exactly 5, 6, 7, 8, 9, or 10 correct answers:
P(pass) = P(5) + P(6) + P(7) + P(8) + P(9) + P(10)
