Answer:

$46.15

Step-by-step explanation:

Given information:

Define the variable:

Convert 4% into a decimal:

\(\implies 4\%=\dfrac{4}{100}=0.04\)

Therefore, the sum of the cost of the juice, the price of the jeans and the sales tax on the jeans must be equal to or less than $50:

\(\implies 2+x+0.04x\leq 50\)

\(\implies 2+1.04x\leq 50\)

Solving the inequality:

\(\implies 2+1.04x\leq 50\)

\(\implies 2+1.04x-2\leq 50-2\)

\(\implies 1.04x\leq 48\)

\(\implies \dfrac{1.04x}{1.04}\leq \dfrac{48}{1.04}\)

\(\implies x\leq 46.15384615\)

Therefore, the maximum price of the jeans Juan can afford is $46.15 (not including sales tax).

The peak runoff using the rational method for the given watershed, we need to calculate the time of concentration (Tc) and the runoff coefficient (C) for each land use area.

Then we can use the rational method equation:

Q = (Ci * A * R) / 360

Where:

Q is the peak runoff (in cubic units per second)

Ci is the runoff coefficient

A is the area (in hectares)

R is the rainfall intensity (in millimeters per hour)

Step 1: Calculate the rainfall intensity (R):

The rainfall intensity can be obtained from rainfall frequency data for the given return period. However, without specific location information, it is not possible to provide an accurate value for the rainfall intensity in area 1 of the United States.

Rainfall data for different areas can vary significantly. Therefore, you will need to refer to local rainfall data or consult relevant authorities to obtain the appropriate rainfall intensity for a 25-year return period in your specific area.

Step 2: Calculate the time of concentration (Tc):

The time of concentration represents the time it takes for the water to travel from the farthest point in the watershed to the outlet. This value depends on the slope, land cover, and other factors. Without specific information about the slope and land cover of the watershed, we cannot provide an accurate estimate of the time of concentration.

Step 3: Calculate the peak runoff for each land use area:

Given the minimum C values for each land use area, we can estimate the peak runoff using the rational method equation.

For the 20 hectares of steep lawns in heavy soil (C = 0.3):

Q1 = (0.3 * 20 * R) / 360

For the 10 hectares of attached multifamily residential area (C = 0.6):

Q2 = (0.6 * 10 * R) / 360

For the 5 hectares of downtown business area (C = 0.9):

Q3 = (0.9 * 5 * R) / 360

Step 4: Calculate the total peak runoff for the watershed:

Q_total = Q1 + Q2 + Q3

Remember to substitute the appropriate rainfall intensity (R) based on the location and return period.

Specific slope and land cover data, the estimations provided are rough approximations. It is recommended to consult local hydrological data or seek assistance from a qualified engineer for a more accurate estimation of peak runoff for a specific watershed.

Answer:

∠m = ∠n + ∠p.

Step-by-step explanation:

The exterior angle of a triangle is always equal to the sum of the two other angles inside a triangle. We can prove this:

Let the third angle in the triangle be ∠q. Therefore:

180 - ∠m = ∠q. (Supplementary angles)

However:

180 - ∠n - ∠p = ∠q. (Sum of interior angles of a triangle)

This means that ∠m and ∠n + ∠q are equal. We can write this as a relationship:

∠m = ∠n + ∠p.

The probability that all 3 cards are clubs will be 0.0129

To find the chance that all three cards are clubs,

We can use the following formula:

\(P(\text{all 3 are clubs}) = \frac{\text{number of favorable outcomes}}{\text{number of possible outcomes}}\)

The number of favorable outcomes is the number of ways to choose 3 clubs from the 13 clubs in the deck, which is given by the given binomial coefficient \({13 \choose 3} = 286\)

The number of possible outcomes is the number of ways to choose 3 cards from the deck, which is given by the binomial coefficient \({52 \choose 3} = 22,!100\)

Therefore, the value of the probability that all 3 cards are clubs is:

\(P(\text{all 3 are clubs}) = \frac{\text{number of favorable outcomes}}{\text{number of possible outcomes}} \\= \frac{286}{22,!100} \\\approx 0.0129\)

AB and YX are corresponding sides, BC and XZ are corresponding sides, and AC and YZ are corresponding sides of given triangle.

What is triangle?

A triangle is a two-dimensional geometric shape that has three sides, three angles, and three vertices. It is one of the simplest polygonal shapes and is commonly studied in geometry.

Since we have:

∠A ≅ ∠Y

∠B ≅ ∠X

∠C ≅ ∠Z

We can conclude that the two triangles ABC and XYZ are similar by the Angle-Angle (AA) similarity theorem.

Therefore, the corresponding sides of the two triangles are proportional to each other. We can write this as:

AB : YX = BC : XZ = AC : YZ

where AB and YX are corresponding sides, BC and XZ are corresponding sides, and AC and YZ are corresponding sides.

In other words, the ratio of the length of each side in triangle ABC to the corresponding side in triangle XYZ is constant.

Answer:

its is6700rr centimeters

Step-by-step explanation:

Answer:1.) To write the equation 4x + y = 10 in slope-intercept form, we need to isolate the y-term on one side of the equation. Subtracting 4x from both sides of the equation gives us y = -4x + 10. This is the slope-intercept form, where the slope is -4 and the y-intercept is 10.

2.) To write the equation 3x - y = 7 in slope-intercept form, we need to isolate the y-term on one side of the equation. Adding y to both sides of the equation gives us 3x = y + 7. Dividing both sides of the equation by 3 gives us x = (1/3)y + 7/3. This is the slope-intercept form, where the slope is 1/3 and the y-intercept is 7/3.

The value of g(f(0)) is -2.
To find g(f(0)), we need to first evaluate f(0) and then substitute the result into the function g(x). Given that f(x) = 2x - 1, we can find f(0) by substituting 0 for x: f(0) = 2(0) - 1 = -1.

Next, we substitute -1 into the function g(x), which is g(x) = 3x - 7. Plugging in -1 for x, we get: g(-1) = 3(-1) - 7 = -3 - 7 = -10.
Therefore, g(f(0)) = g(-1) = -10.To solve for g(f(0)), we first need to find the value of f(0). Given that f(x) = 2x - 1, we substitute 0 for x: f(0) = 2(0) - 1 = -1.
Next, we substitute the value of f(0) into the function g(x). Given that g(x) = 3x - 7, we substitute -1 for x: g(-1) = 3(-1) - 7 = -3 - 7 = -10.
Therefore, g(f(0)) = g(-1) = -10. The correct answer is -10, not -2 as stated in the question. The correct calculation shows that g(f(0)) equals -10, not -2.

The complete question is Which is a better estimate for the volume of a salt shaker? where radius =3 cm and height =5 cm

The expression that fails to compute the area of a triangle correctly is option b: (1 / 2) * b * h.

The correct formula to compute the area of a triangle is one-half times the base multiplied by the height, which can be written as (1/2) * b * h. Option a, c, and d correctly represent this formula. However, option b is incorrect because it uses integer division instead of decimal division.

In option b, (1 / 2) is computed using integer division, which results in truncating the decimal part. Therefore, (1 / 2) evaluates to 0 instead of 0.5. As a result, the expression (1 / 2) * b * h would yield incorrect and significantly smaller results than the actual area of the triangle.

To accurately calculate the area of a triangle using this formula, it is essential to use decimal division or explicitly represent the fraction as a decimal. Options a, c, and d correctly account for this by using either 1.0/2.0 or 0.5, ensuring the proper calculation of the area.

By using Disk Method, the integral that gives the volume of the solid formed by revolving the region about the y-axis of y = x^(11/12) y=1, x=0 is V = π∫(0 to 1) y^(24/11) dy = 11π/35. The option is D) is correct.

To use the Disk Method to find the volume of the solid formed by revolving the region about the y-axis, we can imagine slicing the solid into thin disks perpendicular to the y-axis, with each disk having thickness dy. The total volume of the solid can be found by summing up the volumes of all such disks from y=0 to y=1.

The equation of the curve is y = x^(11/12), so we can solve for x as x = y^(12/11). The region is bounded by y=0, y=1 and x=0.

Now, consider a thin disk located at a distance y from the y-axis. The radius of the disk is given by the distance between the y-axis and the curve at y, which is simply x = y^(12/11). Thus, the radius of the disk is r(y) = y^(12/11). The thickness of the disk is dy.

The volume of the disk is given by the formula for the volume of a cylinder, which is V = πr^2h, where r is the radius of the disk and h is its thickness. Substituting in the values we have for r(y) and dy, we get:

dV = π(y^(12/11))^2 dy

Integrating this expression over the range of y from y=0 to y=1 gives us the total volume of the solid:

V = ∫(0 to 1) π(y^(12/11))^2 dy

Simplifying the integrand, we have:

V = π∫(0 to 1) y^(24/11) dy

Using the power rule of integration, we have:

V = π[(11/35) y^(35/11)](0 to 1)

Evaluating this expression at the limits of integration, we get:

V = π[(11/35) - 0] = π(11/35) = 11π/35

Therefore, the volume of the solid formed by revolving the region about the y-axis is 11π/35 cubic units. The correct answer is D).
