How many times greater is the mass of an uranium atom than the mass of an oxygen molecule? Write your answer in standard notation, rounding to the nearest tenth.

Answer:

D. 35°

Step-by-step explanation:

1. The bottom right angle and 95° add up to 180°. Solve for that angle.

95 + y = 180

y = 85

2. Triangles have a total of 180°. Set up the equation.

60 + 85 + x = 180°

3. Simplify

145 + x = 180

4. Solve for x by subtracting 145 from both sides

x = 35°

Answer:

x = 35

Step-by-step explanation:

The exterior angle of a triangle is equal to the sum of the opposite interior angles

60+x = 95

Subtract 60 from each side

60 +x-60 = 95-60

x = 35

Answer:

\(\boxed{87.5\%}\)

Step-by-step explanation:

Convert fraction to a decimal.

\(\frac{7}{8} =0.875\)

Multiply the decimal by 100.

\(0.875 \times 100= 87.5\)

Answer:

87.5%

Step-by-step explanation:

100 divided by 8 = 12.5

We know that one eighth of 100 is 12.5. Now we multiply an eighth by 7 to get seven-eighths (7/8)

12.5 * 7 = 87.5

So 7/8 as a percent is 87.5%

(a). The domain of the function f(x, y) is all real numbers for both x and y such that y₂-x > 0. (b). The range of the function f(x, y) is all real numbers.  (c). f(r) = 4 ln (r₂ - r). (d) . f(r, y) = 4 ln (y₂ - r).

This means that when both x and y are equal to r, the function becomes 4 ln (r₂ - r). This can be simplified to 4 ln (r₂ - r) = 4 ln r₂ - 4 ln r.

The domain of the function f(r, y) is all real numbers for both r and y such that y₂-r > 0. The range of the function is all real numbers.

To find f(r, y), we first substitute r for both x and y, giving us the expression 4 ln (r₂ - r). This expression can be simplified to 4 ln r₂ - 4 ln r.

Therefore, the domain of the function f(x, y) is all real numbers for both x and y such that y₂-x > 0, and the range of the function is all real numbers. To find f(r, y), we substitute r for both x and y and simplify the expression 4 ln (r₂ - r) to 4 ln r₂ - 4 ln r.

A large sample size is needed to construct a confidence interval for the mean BAC of fatal crashes with a positive BAC because it allows for a better approximation of a normal distribution according to the Central Limit Theorem, reduces the margin of error, and minimizes the impact of outliers in a highly skewed right distribution.

To understand why a large sample size is needed to construct a confidence interval for the mean BAC of fatal crashes with a positive BAC, especially when the histogram of blood alcohol concentrations is highly skewed right.

A histogram of blood alcohol concentrations (BACs) in fatal accidents that is highly skewed right indicates that most of the data points are concentrated on the lower end of the scale, with fewer data points extending to the higher BAC levels. When constructing a confidence interval for the mean BAC of fatal crashes with a positive BAC, a large sample size is necessary for the following reasons:

1. Central Limit Theorem: The Central Limit Theorem (CLT) states that the distribution of sample means approaches a normal distribution as the sample size increases, regardless of the shape of the population distribution. A larger sample size allows for a better approximation of a normal distribution, which is essential for constructing an accurate confidence interval.

2. Decreased Margin of Error: A larger sample size reduces the margin of error in the confidence interval, leading to a more precise estimate of the true population mean. As sample size increases, the standard error of the sample mean decreases, which narrows the confidence interval.

3. Minimizing the Impact of Outliers: In a highly skewed right distribution, there may be extreme values (outliers) on the higher end of the BAC scale. A larger sample size helps to minimize the impact of these outliers on the mean and the confidence interval, leading to a more accurate representation of the true population mean.

Given: A = 43.7°, a = 8.7, and b = 10.3We can find the number of possible triangles by using the Law of Sines, which states that a / sin A = b / sin B = c / sin C, where a, b, and c are the side lengths and A, B, and C are the opposite angles. Let's first use the Law of Sines to find the value of sin B: a / sin A = b / sin B => sin B = b sin A / a.

Substituting the given values, we get: sin B = 10.3 sin 43.7° / 8.7≈ 0.641Now we know the value of sin B. We can use the inverse sine function (sin⁻¹) to find the possible values of angle B: B = sin⁻¹ (0.641)≈ 40.4° or B ≈ 139.6°Note that there are two possible angles for B because sine is a periodic function that repeats every 360°.Now that we know the possible values of angle B, we can use the fact that the sum of the angles of a triangle is 180° to find the possible values of angle C: C = 180° - A - B. For B = 40.4°, we get: C = 180° - 43.7° - 40.4° = 95.9°For B = 139.6°, we get: C = 180° - 43.7° - 139.6° = -2.3°Note that we get a negative value for angle C in the second case, which is not possible because all angles of a triangle must be positive. Therefore, the second case is not valid and we only have one possible triangle. Answer: There is only one possible triangle.

It would be beneficial for the company to use higher-quality components despite the increase in variable expenses.

2-a. From the original data, the net operating income (NOI) of Hermann Corporation can be calculated as follows: Sales revenue = Selling price x Units sold = $90 x 2,000 = $180,000Variable expenses = Variable expenses per unit x Units sold = $63 x 2,000 = $126,000Contribution margin = Sales revenue - Variable expenses = $180,000 - $126,000 = $54,000Fixed expenses = $30,000 Net operating income = Contribution margin - Fixed expenses = $54,000 - $30,000 = $24,000

Now, if the company uses higher-quality components, then: Variable expenses per unit = $63 + $2 = $65Contribution margin per unit = $90 - $65 = $25Units sold = 2,000 x 1.10 = 2,200So, the new net operating income will be: Sales revenue = Selling price x Units sold = $90 x 2,200 = $198,000 Variable expenses = Variable expenses per unit x Units sold = $65 x 2,200 = $143,000Contribution margin = Sales revenue - Variable expenses = $198,000 - $143,000 = $55,000

The autograph of the professional basketball player's was worth $250.00 a year ago.

Given that, in the last year, the value of a professional basketball player's autograph rose 40% and it is now worth $350.00.

To determine it worth a year ago, let's call the original value of the autograph "x".

We know that the value increased by 40%, which means it became:

100% + 40% = 140% of its original value.

We can set up the following equation:

140% × x = 350

(140/100)x = 350

1.4x = 350

To solve for x, we can divide both sides by 1.4:

x = 350 ÷ 1.4

x = 250

The rational equation using expressions that have x² - 9 as their least common denominator (LCD  is :(1/(x-3)) - (1/(x+3)) = 5/(x² - 9)

To write a rational equation using expressions that have x² - 9 as their least common denominator (LCD), we need to create fractions with denominators that include factors of x² - 9.

The expression x² - 9 can be factored as (x - 3)(x + 3). So, our LCD is (x - 3)(x + 3).

Now, let's construct the equation. We can use the factored form of the LCD to create two fractions:

1/(x - 3) and 1/(x + 3)

To combine these fractions, we need to find a common denominator. Since the LCD is (x - 3)(x + 3), we can write the equation as:

(1/(x - 3)) - (1/(x + 3)) = 5/(x² - 9)

In this equation, both fractions have denominators that include the factors of x² - 9, which is our desired LCD.

This rational equation allows us to solve for values of x that make the equation true. By manipulating the equation further, we can find the solutions and determine the values of x that satisfy the equation.
