Step-by-step explanation:

By subtraction method the time taken by her is 4:30 hours.

Total spent by her is $346.4

She has left over $153.6

Subtraction is the system of taken out  a number from another number. It is a primary arithmetic operation which is denoted by a  symbol "-" and it is the method of calculating the difference between two numbers.

such as 9-6=3 18-4=14 etc.

Ms. Jones drove to her hometown for the weekend in Detroit, Michigan. She left at 8:00am and arrived at 12:30pm.

To find the time taken by her we use here subtraction  method for time.

Then the time taken by her= ( 12:30 - 8:00)= 4: 30hrs

Also, she left with $500. On her trip, she spent $135.55 on gas, she stopped for food and spent $24, she went to the movies and dinner while she was home and spent $75.85, she went to the zoo and spent $37, and she spent $74 in Uber rides.

She had $500

Total spent = ( $135.55+$24+$75.85+$37+$74)

                   = $346.4

Again to find that how much money lest to her we use subtraction method.

she has left over $(500- 346.4)

                           = 153.6

Hence, the time taken by her is 4:30 hours.

Total spent by her is $346.4

She has left over $153.6

The statement is true. The DecimalFormat class is part of the Java API, specifically within java.text package, so it is automatically available to your programs. You can use it to format numbers in various ways, such as for displaying currency or percentages.

DecimalFormat is a concrete subclass of NumberFormat that formats decimal numbers. It has a variety of features designed to make it possible to parse and format numbers in any locale, including support for Western, Arabic, and Indic digits. It also supports different kinds of numbers, including integers (123), fixed-point numbers (123.4), scientific notation (1.23E4), percentages (12%), and currency amounts ($123). All of these can be localized.

To obtain a NumberFormat for a specific locale, including the default locale, call one of NumberFormat's factory methods, such as getInstance(). In general, do not call the DecimalFormat constructors directly, since the NumberFormat factory methods may return subclasses other than DecimalFormat. If you need to customize the format object, do something like this:

NumberFormat f = NumberFormat.getInstance(loc);

if (f instanceof DecimalFormat) {

    ((DecimalFormat) f).setDecimalSeparatorAlwaysShown(true);

}

A DecimalFormat comprises a pattern and a set of symbols. The pattern may be set directly using applyPattern(), or indirectly using the API methods. The symbols are stored in a DecimalFormatSymbols object. When using the NumberFormat factory methods, the pattern and symbols are read from localized ResourceBundles

Answer:

C)  (-1, -4) and (4, 6)

Step-by-step explanation:

\(\textsf{Equation 1}:y=2x-2\)

\(\textsf{Equation 2}:y=x^2-x-6\)

Substitute Equation 1 into Equation 2 and solve for x:

\(\implies 2x-2=x^2-x-6\)

\(\implies x^2-3x-4=0\)

Find two numbers that multiply to -4 and sum to -3:  -4 and 1

Rewrite the middle term as the sum of these two numbers:

\(\implies x^2-4x+x-4=0\)

Factorize the first two terms and the last two terms separately:

\(\implies x(x-4)+1(x-4)=0\)

Factor out the common term \((x-4)\):

\(\implies (x+1)(x-4)=0\)

\(\implies (x+1)=0 \implies x=-1\)

\(\implies (x-4)=0 \implies x=4\)

Substitute the found values of x into Equation 1 and solve for y:

\(x=-1 \implies y=2(-1)-2=-4\)

\(x=4 \implies y=2(4)-2=6\)

Therefore, the solution to the system of equations is:

(-1, -4) and (4, 6)

Objective Function and Constraints:

Let:

x1 = amount spent on food

x2 = amount spent on shelter

x3 = amount spent on entertainment

Objective Function:

Maximize: 2x1 + 3x2 + 5x3 (since each dollar spent on food has a satisfaction value of 2, each dollar spent on shelter has a satisfaction value of 3, and each dollar spent on entertainment has a satisfaction value of 5)

Constraints:

Subject to:

x1 + x2 + x3 ≤ $1,500 (maximum disposable income)

x1 + x2 ≤ $1,100 (amount spent on food and shelter combined must not exceed $1,100)

x2 ≤ $800 (amount spent on shelter alone must not exceed $800)

AREA- To find the area you divide the shape

Part 1 - 4* 3 = 12cm^2 Part 2 - 20 * 5 = 100cm^2

Final part ( add part a and b ) - 12 + 100 = 112cm^2

Shape B:

PERIMETER = S + S + S + S + S ..,........ (UNTIL YOU GET TO 12 SIDES PROVIDED THE SHAPE HAS 12 SIDES :) )

Answer:

x = 12

Step-by-step explanation:

To solve this and show your work, you have to start of with the equation (3x - 6) = 30.

You then have to add 6 to both sides like this:

\((3x - 6) = 30 \\ \: \: \: \: \: \: \: \: \: \: + 6 \: \: \: \: \: + 6 \)

So then the 6 is cancelled out, and you are left with

3x = 36.

Now you just have to divide both sides by 3 like this:

\( \frac{3x}{3} = \frac{36}{3} \)

Which cancels 3 out, and you are left with

x = 12.

No, a fraction is not a term. The distributive property can be applied to fractions because it is a general mathematical principle.

A fraction is not considered a term in the traditional sense. It is a mathematical expression that represents division. However, the distributive property can still be applied to fractions because the property itself is a fundamental rule of arithmetic that extends beyond specific types of expressions.

The distributive property states that for any real numbers a, b, and c:

a × (b + c) = (a × b) + (a × c).

When working with fractions, we can apply the distributive property as follows:

Let's consider the expression: a × (b/c).

We can rewrite this as: (a × b)/c.

Now, let's distribute the 'a' to 'b' and 'c':

(a × b)/c = (a/c) × b.

In this step, we applied the distributive property to the fraction (a/c) by treating it as a whole.

Although fractions represent division, we can still use the distributive property because it is a general mathematical principle that allows for manipulating expressions involving addition, subtraction, multiplication, and division.

Scarlett's balance after 3 years is $658.97 to the nearest cent.

The formula to find the balance after t years when principal amount P is invested at an annual interest rate r compounded n times per year is given by:

A = P(1 + r/n)^(n*t)

Here, P = $600, r = 1.8% = 0.018, n = 1 (since interest is compounded annually), and t = 3. Substituting these values in the above formula, we get:

A = 600(1 + 0.018/1)^(1*3) = $658.97

To calculate the total maximum horizontal stress (Shmax) in a subsurface system with reverse faulting, we can use the formula:

Shmax = P / A

where P is the pressure at the given depth and A is the stress ratio. Given: Depth = 2,000 ft, A = 0.8, Friction angle (φ) = 30°

First, we need to calculate the vertical stress (σv) at the given depth using the equation:

σv = ρ g  h

where ρ is the unit weight of the overlying rock, g is the acceleration due to gravity, and h is the depth.

Next, we can calculate the effective stress (σ') using the equation:

σ' = σv - Pp

where Pp is the pore pressure.

Assuming the pore pressure is negligible, σ' is approximately equal to σv.

Finally, we can calculate Shmax using the formula:

Shmax = σ' * (1 + sin φ) / (1 - sin φ)

Substituting the given values into the equations, we can calculate Shmax. However, the unit weight of the rock and the value of g are required to complete the calculation.

The probability that the sample mean will be between $10 and $10.2 is approximately 0.3144 or 31.44%.

To calculate the probability that the sample mean will be between $10 and $10.2, we need to use the properties of the sampling distribution of the sample mean. Under certain assumptions (e.g., a large sample size or normality of the population distribution), the sampling distribution of the sample mean follows a normal distribution.

Given that the population mean is $10.2 and the population standard deviation is $1.4, we can use the Central Limit Theorem to approximate the distribution of the sample mean. The Central Limit Theorem states that for a sufficiently large sample size, the sampling distribution of the sample mean will be approximately normal, regardless of the shape of the population distribution.

In this case, the sample size is 39, which is considered reasonably large. Therefore, we can approximate the distribution of the sample mean as a normal distribution with a mean of $10.2 and a standard deviation of σ/√n, where σ is the population standard deviation and n is the sample size.

The standard deviation of the sample mean is calculated as follows:

Standard deviation of the sample mean = σ/√n = 1.4/√39 ≈ 0.224

To find the probability that the sample mean will be between $10 and $10.2, we need to calculate the z-scores for both values and then use the standard normal distribution (z-distribution) to find the probability.

The z-score for $10 is calculated as follows:

z1 = (10 - 10.2) / (0.224) ≈ -0.893

The z-score for $10.2 is calculated as follows:

z2 = (10.2 - 10.2) / (0.224) = 0

Now, we can use a standard normal distribution table, calculator, or software to find the probabilities associated with these z-scores.

The probability that the sample mean will be between $10 and $10.2 is equal to the probability of having a z-score between -0.893 and 0.

Using a standard normal distribution table or calculator, the probability can be calculated as follows:

P(-0.893 ≤ Z ≤ 0) ≈ P(Z ≤ 0) - P(Z ≤ -0.893)

Looking up the values in a standard normal distribution table or using a calculator, we find:

P(Z ≤ 0) ≈ 0.5 (probability of being less than or equal to the mean)
P(Z ≤ -0.893) ≈ 0.1856

Therefore,

P(-0.893 ≤ Z ≤ 0) ≈ 0.5 - 0.1856 ≈ 0.3144

Hence, the probability that the sample mean will be between $10 and $10.2 is approximately 0.3144 or 31.44%.
