The signs of the coordinates of ΔS'T'U' the x-coordinate is positive and the y-coordinate is negative.

Coordinates are a set of numbers or values that define the position of a point or object in space or on a surface. They are used to locate a point or object in a specific location relative to a reference point, axis, or plane.

The coordinate system is divided into four quadrants, numbered from I to IV, which are separated by the x- and y-axes. The origin is located at the intersection of the x- and y-axes, and has coordinates (0, 0)

The ΔSTU lies in Q3 if it reflected then ΔS'T'U' lies in Q4, it means that the point is located in the fourth quadrant of the Cartesian coordinate system. In this quadrant, the x-coordinates are positive and the y-coordinates are negative.

More specifically, if we assume that the point ΔS'T'U' is represented by the coordinates (x, y), then we have:

x > 0 (because it lies to the right of the y-axis)

y < 0 (because it lies below the x-axis)

For example, if the point ΔS'T'U' has coordinates (3, -2), then it lies in Q4, since the x-coordinate is positive and the y-coordinate is negative.

According to the given information, the number of vowels in the first word is 3x = 3(2) = 6.

An equation is a mathematical statement that asserts the equality of two expressions. It consists of two sides, a left-hand side and a right-hand side, separated by an equal sign. The left-hand side and the right-hand side of an equation contain expressions that may include variables, constants, coefficients, and mathematical operations.

Let the number of vowels in the first word be 3x (since the ratio of vowels in the first word to the second word is 3:5)

Then, the number of vowels in the second word is 5x (since the ratio of vowels in the first word to the second word is 3:5)

Given that the second word contains 10 vowels. So, 5x = 10

Hence, x = 2

Therefore, according to the given information, the number of vowels in the first word is 3x = 3(2) = 6.

Answer:

EF = 3.16

Step-by-step explanation:

Assume the triangles are similar.

BC/EF = BA/ED

7.9/EF = 11/4.4

11(EF) = 4.4 × 7.9

EF = 0.4 × 7.9

EF = 3.16

Answer:

We can use the formula for compound interest:

A = P(1 + r/n)^(nt)

where:

A = the final amount

P = the principal amount (initial investment)

r = the annual interest rate (as a decimal)

n = the number of times the interest is compounded per year

t = the time period in years

In this case, we have:

P = £1430

r = 0.005 (0.5% per month)

n = 12 (compounded monthly)

t = 9/12 = 0.75 (9 months is three-quarters of a year)

So we can plug in these values to find the final amount:

A = £1430(1 + 0.005/12)^(12*0.75)

A ≈ £1481.18

Therefore, the amount of money in the account after 9 months will be approximately £1481.18.

The area of the rectangle is the product of its length and width, while the area of the triangle is half the product of its base and height. The total area of the polygon is 96 [tex]in^{2}[/tex] + 30 [tex]in^{2}[/tex] = 126 [tex]in^{2}[/tex].

A polygon that has sides of varying lengths and unequal angles is said to have irregular sides. A regular polygon, on the other hand, has equal-length sides and angles.

An irregular polygon can have any number of sides, any number of angles, and any shape for its sides. The area and perimeter of irregular polygons must be determined using particular formulae that take into consideration the unique characteristics of each individual polygon since irregular polygons can have a wide range of varied sizes and forms.

To find the area of an irregular polygon, we can divide it into smaller shapes such as triangles and rectangles, find the area of each shape, and add them together.

In this case, we can divide the polygon into a rectangle and a right triangle, as shown in the diagram below:

The area of the rectangle is the product of its length and width:

Area of rectangle = 8 in x 12 in = 96 [tex]in^{2}[/tex]

The area of the triangle is half the product of its base and height:

Area of triangle = 1/2 x 6 in x 10 in = 30 [tex]in^{2}[/tex]

Therefore, the total area of the irregular polygon is:

Area = Area of rectangle + Area of triangle

= 96 [tex]in^{2}[/tex] + 30 [tex]in^{2}[/tex]

The minimum annual interest rate Kyoko should aim for rounding to the nearest hundredth of a percent is [tex]$6.76%$.[/tex]

What is meant by interest rate?

An interest rate is the percentage of principal charged by a lender or received by a depositor in exchange for the use of money, usually expressed as an annual percentage rate (APR). It is the amount of interest charged on a loan or earned on an investment.

Given that Kyoko has [tex]$10,000[/tex] that she wants to invest and her goal is to have [tex]$15,000[/tex] by the time she finishes graduate school in 6 years. Let the minimum annual interest rate be denoted by [tex]$r$[/tex] (in decimal form).

Using the compound interest formula, we have:

[tex]$A = P(1 + \frac{r}{n})^{nt}$[/tex]

where

A is the future value of the investment (which is [tex]$15,000$[/tex] in this case)

P is the present value of the investment (which is [tex]$10,000$[/tex] in this case)

r is the annual interest rate (what we need to find)

n is the number of times the interest is compounded per year (which is 365 since the interest is compounded daily)

t is the time (in years)

Plugging in the given values, we get:

[tex]$15000 = 10000(1 + \frac{r}{365})^{365\times 6}$[/tex]

Taking natural logarithm on both sides, we get:

[tex]$\ln(1.5) = \ln(1 + \frac{r}{365})^{365\times 6}$[/tex]

Using the property of logarithms, we can write the exponent on the right-hand side as:

[tex]$6\cdot 365\cdot \ln(1 + \frac{r}{365})$[/tex]

Dividing both sides by [tex]$6\cdot 365$[/tex] and simplifying, we get:

[tex]$\ln(1.5) = \ln(1 + \frac{r}{365})$[/tex]

[tex]$1.5 = 1 + \frac{r}{365}$[/tex]

[tex]$r = 365\times (1.5-1) = 365\times 0.5 = 182.5$[/tex]

Therefore, the minimum annual interest rate Kyoko should aim for is [tex]$r=182.5%$.[/tex] Rounding to the nearest hundredth of a percent, we get [tex]$6.76%$.[/tex]

The answer is 27 units of potassium. To determine the amount of potassium in the soil sample, we first need to use the given ratio of nitrogen to potassium to find the ratio between their respective quantities in the soil.

The ratio of nitrogen to potassium is 12:9, which can be simplified to 4:3 by dividing both sides by 3. This means that for every 4 units of nitrogen, there are 3 units of potassium in the soil sample. Since we know that the soil sample contains 36 units of nitrogen, we can use the ratio we just found to calculate the amount of potassium. To do this, we can set up a proportion: 4 units of nitrogen : 3 units of potassium = 36 units of nitrogen : x units of potassium

Solving for x, we cross-multiply and simplify:

4x = 3 * 36

4x = 108

x = 27

Therefore, the soil sample contains 27 units of potassium.

In summary, we used the given ratio of nitrogen to potassium to find the ratio between their respective quantities in the soil, and then set up a proportion using the known quantity of nitrogen to solve for the unknown quantity of potassium. The answer is 27 units of potassium.

Let S be the number of specimens and W be the number of weeks.

We know that initially Joe starts with 83 specimens, and every week the number of specimens doubles. Therefore, the equation that represents the scenario is:

S = 83 * 2^(W-1)

Here, (W-1) is used to account for the initial number of specimens already given in the problem.

This equation gives the number of specimens S after W weeks, taking into account the doubling of specimens every week.

By answering the presented question, we may conclude that Therefore, triangle the measure of BCD is 120°.

A triangle is a closed, double-symmetrical shape composed of three line segments known as sides that intersect at three places known as vertices. Triangles are distinguished by their sides and angles.

Triangles can be equilateral (all factions equal), isosceles, or scalene based on their sides.

Triangles are classified as acute (all angles are fewer than 90 degrees), good (one angle is equal to 90 degrees), or orbicular (all angles are higher than 90 degrees) (all angles greater than 90 degrees).

The region of a triangle may be calculated using the formula A = (1/2)bh, where an is the neighbourhood, b is the triangle's base, and h is the triangle's height.

Since triangle ABC is isosceles with AB = BC, angles A and C are also equal to each other. Let x be the measure of angles A and C. Then we have:

angle A + angle B + angle C = 180° (sum of angles in a triangle)

x + 60° + x = 180°

2x + 60° = 180°

2x = 120°

x = 60°

So angles A and C each measure 60°, making triangle ABC an equilateral triangle.

Now, angle BCD is an exterior angle of triangle ABC. By the Exterior Angle Theorem, the measure of angle BCD is equal to the sum of angles A and C:

angle BCD = angle A + angle C = 60° + 60° = 120°

Therefore, the measure of BCD is 120 degrees.

The probability that the sample mean will be greater than M = 10 pounds is 0.9525.

What is probability?

Probability is a measure of the likelihood or chance of an event occurring. It is expressed as a number between 0 and 1, with 0 indicating the event is impossible and 1 indicating it is certain. Probability is used in many fields, including mathematics, statistics, science, and finance.

To solve this problem, we need to use the central limit theorem (CLT), which states that the distribution of sample means will be approximately normal, regardless of the shape of the population distribution, as long as the sample size is large enough.

Since the sample size is small (n = 4), we need to use the t-distribution instead of the normal distribution. However, since the population standard deviation is known, we can use the standard normal distribution with a z-score.

First, we need to calculate the standard error of the mean:

SE = σ / sqrt(n) = 6 / sqrt(4) = 3

Next, we can calculate the z-score:

z = (M - µ) / SE = (10 - 15) / 3 = -1.67

Finally, we can use a standard normal distribution table or calculator to find the probability of a z-score greater than -1.67:

p(M > 10) = P(z > -1.67) = 0.9525 (rounded to four decimals)

Therefore, the probability that the sample mean will be greater than M = 10 pounds is 0.9525.

24x-72=22x+66

2x=138

X=138/2=69

Therefore, the speed of boat is 69 miles per hour or

The boat in the problem travels different distances at different rates, but in the same amount of time for each trip. Distance is rate times time, d=r⋅t, which, solving for t, becomes

t=dr.

The trip against the current has rate r=s−3, so the time it takes to complete the trip is

t=20s−3.

The time it takes to complete the trip with the current is

t=22s+3.

The time to complete each trip is the same, so set the fractions equal to each other.

20s−3=22s+3

Multiply each side by (s−3)(s+3).

20(s−3)(s+3)(s−3)=22(s−3)(s+3)(s+3)

Simplify.

20(s+3)=22(s−3)
