Answer:

How long will it take to hear the rumbling of a volcano located 58km away?

Step-by-step explanation:

Surface area of the cylinder in terms of \($\pi$\) is \($5904\pi m^2$\).

The surface area of a cylinder can be calculated by adding the area of the two bases (which are circles) and the lateral area (which is the area of the curved surface).

The radius of the cylinder is given as 36m and the height as 46m. Therefore, the diameter of the cylinder is 72m (twice the radius). Using the formula for the area of a circle, we can calculate the area of each base:

\($A_{base} = \pi r^2 = \pi (36m)^2 = 1296\pi m^2$\)

The lateral area of the cylinder can be calculated using the formula:

\($A_{lateral} = 2\pi r h$\)

Substituting the given values, we get:

\($A_{lateral} = 2\pi (36m) (46m) = 3312\pi m^2$\)

Therefore, the total surface area of the cylinder is:

\($A_{total} = A_{base} + A_{lateral} + A_{base} = 2A_{base} + A_{lateral}$\)

Substituting the values we calculated, we get:

\($A_{total} = 2(1296\pi m^2) + 3312\pi m^2 = 5904\pi m^2$\)

So the surface area of the cylinder in terms of \($\pi$\) is \($5904\pi m^2$\).

Answer:

Step-by-step explanation:

Answer:

6 and 4

Step-by-step explanation:

the first number is x and the second is y , then triple x is 3x , so

3x + y = 22 → (1)

the second number y is equal to twice x , less 8 , that is 2x - 8 , so

y = 2x - 8 → (2)

solving the 2 equations simultaneously.

substitute y = 2x - 8 into (1)

3x + 2x - 8 = 22

5x - 8 = 22 ( add 8 to both sides )

5x = 30 ( divide both sides by 5 )

x = 6

substitute x = 6 into (2) for y

y = 2(6) - 8 = 12 - 8 = 4

first number is 6 and second number is 4

The discriminant is the bit under the radical, the \(b^2-4ac\).

Because it's under a radical, it's what tells you how many and what kind of solutions you have (two real, one real, or two imaginary/complex solutions).

Does that answer your question?  Or do you need an example?

Suppose you had the equation \(3x^2-7x+1 = 0\), then you'd have:

    \(a=3\), \(b=-7,\) and \(c=1\)

You'd plug those values into \(b^2-4ac\) to see if the discriminant was positive, zero, or negative:

    \(\begin{aligned}b^2-4ac &= (-7)^2-4(3)(1) \\&= 49 - 12 \\&= 37\endaligned}\)

Since that is 37 (a postiive number), you'd have two real solutions.

7a. The ratio of American dollars to Mexican Pesos is given as; American dollars:

Mexican Pesos = 270:3000 or 270/3000:7

b. Let the rate of exchange be $1 = 10 Mexican Pesos

Levant traded 270 American dollars for 3,000 Mexican pesos.

Therefore, the exchange rate he got was; Exchange rate = 3000/270 = 11.

The estimated value of the explanatory variable is not statistically significant at the 5%-level if a. the t-statistic is greater than 2.5.

The t-test is a hypothesis testing technique used to decide whether the estimated coefficient of a linear regression model is statistically significant or not. The t-value is used to measure the size of the difference between the estimated coefficient and the hypothesized value. When the t-value exceeds a critical value, such as 2.5, the estimated value of the explanatory variable is not significant at the 5%-level. It implies that the null hypothesis, which assumes that the explanatory variable's coefficient is zero, cannot be rejected.

The p-value is a measure of the probability of obtaining a more extreme value of the test statistic than the observed value if the null hypothesis is true. A small p-value implies that the null hypothesis should be rejected. When the p-value is less than 0.05, it means that the estimated value of the explanatory variable is significant at the 5%-level.

The confidence interval is a range of values that is expected to include the true value of the population parameter with a specified level of confidence. A 95% confidence interval means that the true value of the population parameter lies within the range 95% of the time. The 95% confidence interval does not contain zero implies that the estimated value of the explanatory variable is statistically significant at the 5%-level since it suggests that the population parameter is different from zero at the 5%-level. Conversely, if the 95% confidence interval contains zero, the estimated value of the explanatory variable is not statistically significant at the 5%-level since it means that the population parameter is not different from zero at the 5%-level. Therefore, it is essential to examine the t-statistic, p-value, and confidence interval while conducting hypothesis testing to make an informed decision.

No, there is no commutative property of subtraction for rational numbers. The commutative property, which states that the order of operands does not affect the result of an operation, does not apply to subtraction for rational numbers.

The commutative property states that the order of the operands does not affect the result of an operation. For addition and multiplication, the commutative property holds true. However, for subtraction, the order of the operands does matter, and thus, the commutative property does not apply.

Let's consider an example to demonstrate this:

Take the rational numbers 3/4 and 1/2.

If we subtract 3/4 from 1/2, we have: 1/2 - 3/4 = (2/4) - (3/4)

= -1/4.

If we subtract 1/2 from 3/4, we have: 3/4 - 1/2 = (3/4) - (2/4)

= 1/4.

As you can see, the results are different when the order of subtraction is changed, indicating that subtraction does not follow the commutative property for rational numbers.

The commutative property, which states that the order of operands does not affect the result of an operation, does not apply to subtraction for rational numbers. Changing the order of subtraction changes the result, making subtraction non-commutative for rational numbers.

The commutative property does not apply to the operation of subtraction with rational numbers. This is because changing the order of the numbers in a subtraction operation will give a different result.

In mathematics, the commutative property refers to the idea that the order in which numbers are used in an operation does not change the result of that operation. This property holds true for addition and multiplication but, unfortunately, it does not hold true for subtraction and division. For example, in subtraction, if we take two rational numbers such as 5 and 3, 5 - 3 is equal to 2, but 3 - 5 equals to -2. As you can see, changing the order of the numbers gives us different results, demonstrating that there is no commutative property of subtraction for rational numbers.

The conversion factor to convert cm/s to m/min is 3 / 5, it is gained by applying the knowledge of conversion of units to the given problem.

What do you mean by conversion of units?

Conversion of units deals with the method of converting a set of values given in a unit to another unit without changing its numerical value. Conversion can take place in both ways, from lower to higher units and vice-versa.

Calculation of the conversion factor to convert cm/s to m/min

We know that,

1 m = 100 cm

1 min = 60 s

To convert cm/s to m/min, we have

= 18 / (100 / 60)

= (18 × 3) / 5

= 54 / 5

= 10.8 m/min

Hence, the conversion factor used to convert cm/s to m/min is 3 / 5.

The base is 5.5 ft.

The width is 2.5 ft.

The height is 3.5 ft.

So, simply just multiply all three of these numbers together.

5.5 × 2.5 = 13.75

The solutions of the equation x+14/x = -9 is x=-2 and x=-7.

The given equation is x+14/x = -9.

Multiply both sides by x:

x( x+14/x) = -9x.

x² +14/x(x) =-9x

x² +14=9x

Now take all the terms to one side by subtracting 9x from both sides:

x² +9x+14=-9x+9x

x² +9x+14=0

The given equation is in the form of quadratic equation ax² +bx+c=0.

We can factor out this quadratic equation.

x² +7x+2x+14=0

Factor out the greatest common factors.

x(x+7)+2(x+7)=0

(x+2)(x+7)=0

Now have to equate each factor to zero:

x+2=0 so x=-2

x+7=0, so x=-7

Hence, the solutions of the equation x+14/x = -9 is x=-2 and x=-7

The value of X is normally distributed   such that only 8% of values are below it is approximately 38.76.

To find the value of X such that only 8% of values are below it, we need to find the z-score associated with the 8th percentile and then convert it back to the X value using the mean and standard deviation.

Step 1: Find the z-score associated with the 8th percentile.

Using a standard normal distribution table or calculator, we find that the z-score associated with the 8th percentile is approximately -1.4051.

Step 2: Convert the z-score back to the X value.

We can use the formula for z-score:

z = (X - mean) / standard deviation

Rearranging the formula to solve for X, we have:

X = z * standard deviation + mean

Plugging in the values:

X = -1.4051 * 8 + 50

X ≈ 38.76

Therefore, the value of X such that only 8% of values are below it is approximately 38.76.
