Given the proportional graphs represnting the ride of Kiran and Mai, thus:

Recall:

A proportional graph has a line that passes through the origin (0, 0), and also has a constant of proportionality, k.

Constant of proportionality, k = y/x.

1. Given that Kiran rides for 4 miles in 16 minutes, therefore the upper graph that passes through point (4, 16) goes with Kiran.

Given that Mai's points include (1, 3), (4, 12), and (10, 30), these points are on the lower graph, therefore, the lower graph goes with Mai.

2. The graph with the smallest constant of proportionality value represents the graph that goes with the fastest rider. The constant of proportionality in this case represents how many minutes spent on covering 1 mile. The shorter the minutes, the faster.

k = y/x = 16/4 = 4 mins per mile

k = y/x = 3/1 = 3 mins per mile

3. At 20 minutes, using the graph given, Kiran will be at 5 miles far.

At 20 minutes, Mai will be at almost 7 miles.

4. At the end of 12 mile path, the graph shows that Kiran will have used 48 minutes (12, 48), while Mai would have used 36 minutes (12, 36).

The relationship between numbers divisible by 6, 2, and 3 is that they are all multiples of 6.

The numbers divisible by 6, 2, and 3 are those that can be evenly divided by all three of these numbers.

To understand this relationship, we need to consider the factors of 6. The factors of 6 are 1, 2, 3, and 6. Since a number divisible by 6 must also be divisible by 2 and 3, it means that it must have both 2 and 3 as factors. For example, 12 is divisible by 2 and 3 because it can be divided evenly by both of these numbers. Similarly, 24, 36, 48, and so on, are all divisible by 6, 2, and 3 because they have both 2 and 3 as factors. In other words, any number that is divisible by 6 is also divisible by 2 and 3 because these numbers are factors of 6.

20% of 50 is 10. 20% of 50 is 10. Warm-up time is 60 minutes and practice is 20% of that.

Solution:

Given, Warm-up time = 60 minutes

Now, Practice is 20% of Warm-up

time= (20/100) × 60= 12 minutes

Thus, 20% of Warm-up time is 12 minutes.

So, 20% of 50 is:

20% of 50 = (20/100) × 50= 10

Hence, 20% of 50 is 10. 20% of 50 is 10.

Additional comment

You know the contents of each radical must not be negative. That means 2x-8 ≥ 0, or x≥4. We know x=4 doesn't work in the equation (0≠√8), so we only need to check the answers x=12 and x=7. Of those, only x=12 satisfies the equation.

False. It is necessary to have a base case in all recursive algorithms.

A base case is a condition that stops the recursion process and returns a result. Every recursive algorithm must have a base case. The base case is the point at which the recursion will stop, and the function will begin to return the values from the call stack. The base case is necessary to stop the recursive algorithm from entering an infinite loop that will cause it to consume all available resources, resulting in a stack overflow error. If there is no base case, the algorithm will continue to call itself until the stack overflows, which will result in a runtime error.

In conclusion, a base case is essential in all recursive algorithms, and the lack of one can result in a stack overflow error.

The volume of the solid enclosed by the surface z = sqrt\((4 - x^2 - y^2\\\)) and the plane z = 0 is (16/3)π.

To determine the volume of the solid enclosed by the surface z = sqrt\((4 - x^2 - y^2\)) and the plane z = 0, we need to set up a triple integral over the region R in the xy-plane where the surface intersects with the plane z = 0.

The surface z = sqrt(4 - x^2 - y^2) intersects with the plane z = 0 when 4 - \(x^2 - y^2\) = 0, which is the equation of a circle of radius 2 centered at the origin. So, we need to integrate over the circular region R: \(x^2 + y^2\) ≤ 4.

Thus, the volume enclosed by the surface and the plane is given by:

V = ∬(R) f(x,y) dA

where f(x,y) = sqrt(4 - \(x^2 - y^2\)) and dA = dx dy is the area element in the xy-plane.

Switching to polar coordinates, we have:

V = ∫(0 to 2π) ∫(0 to 2) sqrt(4 - \(r^2\)) r dr dθ

Using the substitution u = 4 - r^2, we have du/dx = -2r and du = -2r dr. Thus, we can write the integral as:

V = ∫(0 to 2π) ∫(4 to 0) -1/2 sqrt(u) du dθ

= ∫(0 to 2π) 2/3 (\(4^(3/2)\)- 0) dθ

= (16/3)π

Therefore, the volume of the solid enclosed by the surface z = sqrt(4 - \(x^2 - y^2\)) and the plane z = 0 is (16/3)π.

Answer:

The expression 75ℎ represents the total charge for Elegance Home Architects.

If the Johnson family hires the design firm for 15 hours, then Elegance Home Architects will be cheaper.

If the Johnson family hires the design firm for 40 hours, then Rock the House Digital Designs will be cheaper.

Step-by-step explanation:

Given the following :

Rock the house digital designs :

Initial consultation charge = $500

Additional hour of work for house plan = $50 /hr

Elegant Home Architect:

Charge = $75 / hr

h = number of hours fro which Johnson's family hires the design firm

Total amount charged by Elegant home Architect = 75 × h = 75h

Total amount charged by Rock the house digital design = (500 + 50h)

If h = 15 hours :

Total amount charged by Elegant home Architect = 75 × 15 = $1,125

Total amount charged by Rock the house digital design = (500 + 50(15)) = 500 + 750 = $1,250

Hence, Elegant home Architect is cheaper.

If h = 40 hours :

Total amount charged by Elegant home Architect = 75 × 40 = $3,000

Total amount charged by Rock the house digital design = (500 + 50(40)) = 500 + 2000 = $2,500

Hence, Rock the house digital design is cheaper.

The correct equations to represent Ted's total September costs are: (3600+ 1.50) x 12.000 1.50(3600+) 12,000.

Cost is the total expenditure or loss incurred in the production, acquisition, or use of a product or service. It can be calculated as the sum of fixed costs (such as rent and labor costs) plus variable costs (such as materials and energy). Cost can be expressed both in monetary terms (such as dollars or euros) or in terms of resources (such as time or effort). In business, cost is a crucial factor for determining profitability and should be taken into consideration when making decisions about production, sales, and pricing strategies.
The first equation calculates the cost of the fixed monthly costs plus the cost of the 16 ounce bags of coffee multiplied by the total number of bags sold.

The height of the free-surface above the base in the conical tank, when 1 liter of water is poured into it, is approximately 3.18 cm.

To find the height of the free-surface above the base, we need to calculate the volume of the conical tank and then determine the corresponding height for a volume of 1 liter.

The volume of a cone is given by the formula V = (1/3)πr²h, where V is the volume, π is a mathematical constant (approximately 3.14159), r is the radius of the base, and h is the height of the cone.

Given that the base diameter is 20 cm, the radius (r) can be calculated as half the diameter, which is 10 cm or 0.1 meters. The height of the cone is given as 20 cm or 0.2 meters.

Substituting these values into the volume formula, we have V = (1/3) * 3.14159 * \((0.1)^2\) * 0.2 = 0.00418879 cubic meters.

Since 1 liter is equal to 0.001 cubic meters, we can calculate the height (h') for a volume of 1 liter: 0.001 = (1/3) * 3.14159 *\((0.1)^2\) * h'.

Simplifying the equation, we find h' = 0.001 / (0.00418879) ≈ 0.239 cm.

However, this is the height from the apex of the cone. To find the height of the free-surface above the base, we subtract the height of the apex from the total height of the cone: 0.2 - 0.239 ≈ 0.03 cm.

Therefore, the height of the free-surface above the base, when 1 liter of water is poured into the conical tank, is approximately 3.18 cm.

The length of BC is 10cm, in the given triangle.

What is are of the triangle?

The territory included by a triangle's sides is referred to as its area. Depending on the length of the sides and the internal angles, a triangle's area changes from one triangle to another. Square units like m2, cm2, and in2 are used to express the area of a triangle.

BR = 3 cm, let's say AR = 4 cm, and AC = 11 cm.

Since tangents to an exterior point are always equal, we can conclude that BR = BP = 3 cm.

4 cm if AQ = AR

QC=AC-AQ=11 – 4 = 7 cm

Q = P = 7 cm

It follows that BC = BP+PC = 3 + 7 = 10 cm.

BC, therefore, has a length of 10 cm.

Therefore, BC is 10 cm long.
