Solving for UY. in the figure provided where VX is a midsegment of UWY,  UY is 90

When the comparable triangles' angles are congruent and their respective sides are proportionate, this is referred to as similar triangles in geometry.

In light of this, if the triangle's corresponding angles are congruent, then the side should be proportionate.

For the given figure, the proportionate sides are

WV and VX, WU and UY

Solving for P

WV / VX = WU / UY

1 / (20p - 95) = 2 / (13p - 1)

cross multiplying

13p - 1 = 2(20p - 95)

13p - 1 = 40p - 190

collecting like terms

190 - 1 = 40p - 13p

189 = 27p

p = 7

solving for UY

= 13p - 1

= 13 * 7 - 1

The geometric series is 6, -30, 150, -750, 3750, -18750 and the sum of the geometric series is -15624.

A geometric series is a sequence of numbers where each term is obtained by multiplying the previous term by a fixed number called the common ratio.

The geometric series that starts with 6, ends with -18,750, and has a common ratio of -5 is:

6, -30, 150, -750, 3750, -18750.

The sum of the geometric series is the sum of all the terms in the series. To find the sum of the series, you can use the formula:

S = a(1 - rⁿ)/(1 - r)

Where:

S is the sum of the series

a is the first term of the series

r is the common ratio

n is the number of terms in the series

In this case, a = 6, r = -5 and n = 6. Thus:

S = 6(1 - (-5)⁶)/(1 - (-5))

S = 6(1 - 15625)/(1 + 5)

S= 6(-15624)/6

S = -15624

Therefore , the solution of the given problem of speed comes out to be

v=10mph is the michael speed in  water.

Distance-based speed is a gauge of how quickly something is moving. The amount of distance a moving object may move in a certain length of time depends on its speed. Speed is calculated using the following equation: velocity = distance x time. The most used units for gauging speed are meters per second (m/s), kilometers per hour (km/h), and kilometers per second (mph) (mph).

Here,

Given :The issue can be rapidly resolved after an equation has been established. Consider the equation time = distance/velocity. Let the speed of moving water equal v. The distance, 182 miles, will be the same both ways.

Downstream time =182/(v+3)

Downstream time + 12 = 182 (v-3)

Set t to the downstream time. Set t=t!

182/(v+3) = 182/(v-3) - 12

Denominators are eliminated by dividing both side by (v+3) (v-3).

12v2 turns out to equal 1200.

Hence, v=10 mph!

Therefore , the solution of the given problem of speed comes out to be

The slope of a line that is perpendicular to the line through the points is - 25/123

The change in the y-coordinate relative to the change in the x-coordinate of a line is referred to as the slope of that line. The net change in the y-coordinate is y, while the net change in the x-coordinate is x. As a result, the change in the y-coordinate with regard to the change in the x-coordinate may be expressed as,

The inverse of a point (1, 2) on a graph would be the point (2, 1) because it's the reflection of the point (1, 2) over the line y = x.

In general, the inverse of a point (x, y) on a graph is the point (y, x). This is because when we switch the x and y coordinates of a point, we are reflecting it over the line y = x, which is the line of symmetry of the inverse function.

Inverse functions are mathematical operations that "reverse" each other. For example, if f(x) = 2x, then the inverse function f^-1(x) = x/2, when you apply f(x) and then f^-1(x) to a number you'll get the same number, so f^-1(f(x))=x, that's why they are called inverse.

area of rectangle: 11 x twice the radius

radius = 2

A(rect): = 11(4) = 44 sq units

A (semi-circle) = (π·r²) / 2

A = 4π / 2 = 2π = 6.28 sq units

44.0 + 6.28 = 50.28

Answer: B square root of 40

Step-by-step explanation:

You're trying to find the length of the hypotenuse so you need to use the formula a^2 + b^2 = c^2

c = x

a = 2

b = 6

So 2^2 + 6^2 = x^2

The square that must be cut from each corner of the cardboard to form a box with a volume of 288 cubic inches is 2.4 inches on each.

Square is a two-dimensional shape with four equal sides and four right angles. It is one of the most common shapes in geometry. Squares have many practical uses, such as in forming grids, creating patterns, and making tiling. Squares are also used in art and architecture, as well as in construction, mathematics, and science.
To solve this problem, we will use the formula for the volume of a rectangular box, V = lwh. We can substitute the given values to solve for x. First, we will find the length and width of the box after the square corners are cut out:

Length = 20 - 2x

Width = 14 - 2x

Now, substituting these values into the volume formula, we get:

288 = (20 - 2x)(14 - 2x)h

Expanding and simplifying, we get:

288 = 280 - 56x + 4x^2

Subtracting 280 from both sides, we get:

8 = -56x + 4x^2

Solving for x, we get:

4x^2 - 56x + 8 = 0

Using the quadratic equation, we get x = 2.4 or x = 0.4

Since x must represent a length, we can discard the negative solution, x = 0.4. Therefore, the square that must be cut from each corner of the cardboard to form a box with a volume of 288 cubic inches is 2.4 inches on each.

It is often used in architecture, as well as in signage and logo designs. Octagons can also be found in nature, such as in the shape of honeycomb cells, some flower petals, and certain animal eyes.

To calculate the area of an octagon, we need to first calculate the length of the side. To do this we use the formula for the perimeter of an octagon: P = 8s, where s is the length of the side. Solving for s: s = P / 8.

The perimeter of the octagon is 80 cm. So the length of the side is 80 cm / 8 = 10 cm. Now we can use the formula for the area of an octagon: A = 2(1 + √2) s^2. Plugging in our value for s, we get: A = 2(1 + √2) (10 cm)^2 = 628.3 square cm. The area of the octagon, to the nearest square centimeter, is 628 cm^2.

The 98% confidence interval for the difference in proportions of tails side up for a penny and a dime would lie between -0.2 and 0.6.

Statistics is a branch of mathematics that deals with the collection, analysis, interpretation, and presentation of data. It is used to summarize, analyze, and compare data in order to draw conclusions and make decisions. Statistical methods are used in a wide variety of fields, including economics, finance, business, engineering, medicine, psychology, social sciences, and many others.

Statistics helps us to understand the behavior of a large number of variables by studying their distributions, relationships, and other patterns. Statistical methods are used to describe and summarize the data, estimate parameters of the population, test hypotheses, and make predictions. Statistical analysis can be used to draw conclusions about the population based on sample data and to determine the probability of certain events occurring. Statistical techniques are used to identify trends and patterns in data, as well as to assess relationships between variables.


This confidence interval can be calculated using the formula for a confidence interval for two proportions, which is: CI = p1 - p2 ± (1.96 x √[(p1(1-p1)/n1) + (p2(1-p2)/n2)]).

In this case, p1 is the proportion of times a spinning penny lands with tails up (18/30 = 0.6), p2 is the proportion of times a spinning dime lands with tails up (20/30 = 0.67), n1 is the number of times the penny was spun (30) and n2 is the number of times the dime was spun (30). Plugging these values into the formula yields a confidence interval of -0.2 and 0.6.

This means that we can be 98% confident that the difference in proportions of tails side up for a penny and a dime lies between -0.2 and 0.6.

Step 8: We can calculate the probability by dividing the number of outcomes that result in doubles and sum less than 7 by the number of outcomes that result in a sum less than 7.

5/18 = 0.278

Final Answer: The probability of rolling doubles, given that the sum on the two dice is less than 7, is 0.278 or 27.8%.
