A restaurant uses rectangular napkins where the length, l, is twice as long as the width. The length of the napkin along the diagonal is x. What is x in terms of l? Replace a and b with the correct values.

Answer:

Will usually be labelled?

Answer: It should say either in the equation itself, or in the directions

Step-by-step explanation:

If the instructions don't say which variable you're solving for, you can figure it out by looking at the equation

For example, we have this equation

\(9x+3=21\)

In this equation, there is only one variable to solve for, and that variable is x

\(y=15-\sqrt{16}\)

In this equation, there is only one variable to solve for, and that variable is y

However, if you're given an equation with more than one variable, most of the time, you have to solve for both!

Answer:

Therefore, based on the given scatter plot, the set of numbers that matches the points is C. 8,9,8,10,8,11.

Step-by-step explanation:

The scatter plot shown represents a set of nine points on a coordinate plane. Each point consists of an x-coordinate and a y-coordinate. To determine which set of numbers corresponds to the scatter plot, we need to analyze the pattern in the given points.

Looking at the scatter plot, we observe that the x-coordinates range from 0 to 10 with an increment of 1, while the y-coordinates seem to vary.

Now let's examine the given answer choices:

A. .4,4,5,5,6,6

B. .4,10,4,11,4,12

C. 8,9,8,10,8,11

D. 10,10,10,11,10,12

Set C (8,9,8,10,8,11) among these answer choices matches the pattern observed in the scatter plot. The x-coordinates in the scatter plot range from 0 to 10, and the y-coordinates correspond to the numbers provided in set C.

Therefore, based on the given scatter plot, the set of numbers that matches the points is C.

Answer:

50 grams

Step-by-step explanation:

36 grams = 72%

→ Find 1% by dividing both sides by 72

0.5 grams = 1%

→ Times both sides by 100 to find 100%

50 grams = 100%

Step-by-step explanation:

Multiply 32 by 72 to get thw mass.

well, for the piece-wise function, we know that hmmm x = -1, -1 is less 1, so the subfunction that'd apply to that will be -2x + 1, because on that section "x is less than or equals to 1".

so f(-1) => -2(-1) + 1 => 3.

Answer:3

Step-by-step explanation:

In this case x=-1 so you will use the top equation because x<1

so f(-1) = -2(-1) + 1

          = 2+1

           =3

The energy use for each quarter in year 26, starting with the winter quarter, is

Winter: 120.4

Spring: 120.9

Summer: 121.3

Fall: 121.7

The energy use for each quarter in year 26, we need to multiply the quarterly energy use factor (D) by the respective seasonal factors for each quarter.

D = 77.0 + 0.43Q

Q = 1 for the winter of Year 1

Let's calculate the energy use for each quarter in year 26:

For the winter quarter (Q = 101):

D = 77.0 + 0.43(101)

D = 77.0 + 43.43

D = 120.43 (rounded to one decimal place)

For the spring quarter (Q = 102):

D = 77.0 + 0.43(102)

D = 77.0 + 43.86

D = 120.86 (rounded to one decimal place)

For the summer quarter (Q = 103):

D = 77.0 + 0.43(103)

D = 77.0 + 44.29

D = 121.29 (rounded to one decimal place)

For the fall quarter (Q = 104):

D = 77.0 + 0.43(104)

D = 77.0 + 44.72

D = 121.72 (rounded to one decimal place)

Therefore, the energy use for each quarter in year 26, starting with the winter quarter, is approximately:

Winter: 120.4

Spring: 120.9

Summer: 121.3

Fall: 121.7

To determine how much you should expect to pay for gas in Philadelphia versus Cleveland, we need to compare the transportation expenses in both cities. Based on the given data, the transportation expenses are as follows:

Philadelphia: $117

Cleveland: $106

To calculate the expected gas prices, we need to consider the transportation expenses relative to the national average. The formula to find the expected gas price is:

Expected Gas Price = National Average * (Transportation Expense / National Average)

National Average for gas = $2.59

For Philadelphia:

Expected Gas Price in Philadelphia = $2.59 * ($117 / 92) ≈ $3.30

For Cleveland:

Expected Gas Price in Cleveland = $2.59 * ($106 / 78) ≈ $3.51

Comparing the expected gas prices, we find that:

A. $3.03 / $2.75: This option does not match the expected gas prices in Philadelphia and Cleveland.

B. $1.95 / $2.59: This option does not match the expected gas prices in Philadelphia and Cleveland.

C. $2.34 / $2.75: This option does not match the expected gas prices in Philadelphia and Cleveland.

D. $2.75 / $3.24: This option matches the expected gas prices in Philadelphia and Cleveland.

Therefore, the correct answer is:

D. $2.75 / $3.24

The correct answer to the multiple-choice question is B) 0.2294. To answer this question, we need to use the properties of the normal distribution.

We know that the distribution of scores is normal with a mean of 560 and a standard deviation of 90. We want to find the percentage of examinees who score between 600 and 700.

To do this, we first need to standardize the scores using the formula z = (x - μ) / σ, where x is the score, μ is the mean, and σ is the standard deviation. For a score of 600, the standardized score is z = (600 - 560) / 90 = 0.44. For a score of 700, the standardized score is z = (700 - 560) / 90 = 1.56.

Next, we look up the percentage of examinees who score between these two standardized scores using a standard normal distribution table or a calculator. The percentage of examinees who score between 0.44 and 1.56 is approximately 0.2294 or 22.94%.

Therefore, the correct answer to the multiple-choice question is B) 0.2294.

Step-by-step explanation:

By the late 1820s, Mexican ranchos in California were raising cattle specifically for their hides and tallow. These ranchos were established by the Spanish and Mexican settlers, who brought with them the tradition of raising cattle for their leather and fat.

The hides were used for making leather goods, while the tallow was used for making candles and soap.
The Mexican ranchos were known for their large herds of cattle, which roamed freely on vast open ranges. The rancheros, or ranch owners, employed vaqueros, or cowboys, to tend to the herds. The vaqueros were skilled horsemen who could round up and brand the cattle, as well as drive them to market.
The Mexican ranchos played a significant role in the development of California's economy and culture. The hides and tallow produced by these ranchos were in high demand, both locally and internationally. The ranchos also influenced the cuisine of California, introducing dishes such as carne asada and chile con carne.
Today, the legacy of the Mexican ranchos can still be seen throughout California, from the names of towns and streets to the tradition of rodeos and cattle drives. The Mexican ranchos represent an important chapter in California's history and a testament to the enduring influence of Mexican culture on the state.

The expression, a² + b²​

The above expression is a sum expression and it can be calculated from the following

(a + b)²​ = a² + b²​ + x

True. A t-test is a statistical test used to determine if there is a significant difference between the means of two groups. It is used when the sample size is small, and the population standard deviation is unknown.

In contrast, a z-score is calculated using the population mean and standard deviation and is used to compare a sample with a known population. The t-test, on the other hand, uses the sample mean and standard deviation to estimate the population parameters. Therefore, a t-test requires less information from the population than a z-score, making it a more practical choice when the population parameters are unknown or difficult to obtain.

The system capacity or design life level (DDL) of the stormwater collection system is :

1.616 million gallons per day.

To compute the system capacity or design life level (DDL) for a stormwater collection system with a mean drainage loading of 1.2 million gallons per day (mgd), a standard deviation of 0.4 mgd, a design life of 15 years, and a maximum risk of failure of 0.15 over its design life, follow these steps:

1. Determine the z-score for the maximum risk of failure (0.15) using a standard normal distribution table or calculator. The z-score represents the number of standard deviations away from the mean for a given probability.

2. Since the risk of failure is 0.15, we want to find the z-score associated with the probability of 1 - 0.15 = 0.85. Using a standard normal distribution table or calculator, the z-score for 0.85 is approximately 1.04.

3. Calculate the drainage loading at the design life level (DDL) using the formula: DDL = mean + (z-score × standard deviation).

4. Substitute the given values into the formula: DDL = 1.2 + (1.04 × 0.4) = 1.2 + 0.416 = 1.616 mgd.

So, the system capacity of the stormwater collection system is 1.616 million gallons per day (mgd).
