Pythagorean Theorem

Answer:

∠ G = 73° , ∠ H = 98°

Step-by-step explanation:

EFGH is a cyclic quadrilateral, its 4 vertices lie on the circle.

the opposite angles sum to 180°

A

∠ E + ∠ G = 180° , that is

11x + 8 + 8x + 1 = 180

19x + 9 = 180 ( subtract 9 from both sides )

19x = 171 ( divide both sides by 19 )

x = 9

Then

∠ G = 8x + 1 = 8(9) + 1 = 72 + 1 = 73°

B

∠ H + ∠ F = 180° , that is

6y - 4 + 5y - 3 = 180

11y - 7 = 180 ( add 7 to both sides )

11y = 187 ( divide both sides by 11 )

y = 17

Then

∠ H = 6y - 4 = 6(17) - 4 = 102 - 4 = 98°

Answer:

A)  m∠G = 73°

B)  m∠H = 98°

Step-by-step explanation:

The diagram shows a cyclic quadrilateral.

A cyclic quadrilateral is a four-sided shape drawn inside a circle, where every vertex touches the circle's circumference.

As the opposite angles in a cyclic quadrilateral add up to 180°, then:

We can use these equations to find the values of x and y.

m∠E + m∠G = 180°

(11x + 8)° + (8x + 1)° = 180°

11x + 8 + 8x + 1 = 180

19x + 9 = 180

19x + 9 - 9 = 180 - 9

19x = 171

19x ÷ 19 = 171 ÷ 19

x = 9

m∠H + m∠F = 180°

(6y - 4)° + (5y - 3)° = 180°

6y - 4 + 5y - 3 = 180

11y - 7 = 180

11y - 7 + 7 = 180 + 7

11y = 187

11y ÷ 11 = 187 ÷ 11

y = 17

Now we have found the values of x and y, substitute them back into the angle expressions to find m∠G and m∠H.

m∠G = (8x + 1)°

m∠G = (8(9) + 1)°

m∠G = (72 + 1)°

m∠G = 73°

m∠H = (6y - 4)°

m∠H = (6(17) - 4)°

m∠H = (102 - 4)°

m∠H = 98°

The location of the point on the number line that is of the way from A = -4 to B = 17 would be 9.

We can calculate it as follows:

Total distance between -4 and 17 is 17 - (-4) = 21

We want the point that is of the way from -4 to 17. Since 4/5 = 0.8, we multiply 21 by 0.8 which gives 16.8.

Rounding 16.8 to the nearest integer gives us 9.

Therefore, the answer is OD: 9

The volume of the pyramid is 357.7 inches³.

The volume of the cone is 1230.9 yard³.

The volume of a pyramid can be represented as follows;

volume of the pyramid = 1 / 3 Bh

where

Therefore,

B = 10 × 8 = 80 inches²

Hence,

h² =  14² - 4²

h = √196 - 16

h = √180

h = √180 inches

volume of the pyramid = 1 / 3 × 80 × √180

volume of the pyramid = 357.7 inches³

Therefore, let's find the volume of the cone.

volume of the cone = 1 / 3 πr²h

h = √25² - 7²

h = √576

h = 24 yards

volume of the cone = 1 / 3 × 3.14 × 7² × 24

volume of the cone = 1230.9 yard³

The reduced row echelon form of a matrix allows us to determine whether the associated linear system is consistent or inconsistent, unique or has infinitely many solutions.

In reduced row echelon form, a matrix has the following properties:

Each leading entry (the leftmost nonzero entry) of a row is equal to 1.

Each leading entry is the only nonzero entry in its column.

All entries below a leading entry are zeros.

The leading entry in each row is to the right of the leading entry in the row above it.

Based on these properties, we can make the following conclusions about the solution to the associated linear system:

Consistency: If there are no rows of the form [0 0 ... 0 | b] (where b is a nonzero constant), meaning there are no contradictory equations, the linear system is consistent. In other words, there is at least one solution.

Uniqueness: If there are no free variables (columns without leading entries), meaning each column corresponds to a pivot column, the linear system has a unique solution. This means there is only one set of values for the variables that satisfies all the equations.

Infinite solutions: If there are one or more free variables, the linear system has infinitely many solutions. This occurs when there are more variables than equations or when there are dependent equations.

The reduced row echelon form provides an organized representation of the linear system that simplifies the process of determining its solution. By analyzing the structure of the matrix, we can determine the consistency, uniqueness, and the nature of the solution set.

The enough evidence to support the claim that the wait time to see an IRS representative is more than 50 minutes at a 0.100 level of significance.

The null hypothesis is, H0:

µ ≤ 50 minutes.

The alternative hypothesis is,

Ha: µ > 50 minutes.

The significance level is α = 0.100Sample size = 300

Sample mean (x) = 52 minutes

Sample standard deviation (s) = 4 minutes

We have to find whether there is enough evidence to support the claim that the waiting time to see an IRS representative is more than 50 minutes or not.

For that, we perform a one-sample t-test.

The test statistic is given by:

t = (x - µ) / (s/√n)t

= (52 - 50) / (4/√300)t

= 7.905

Critical t-value = t 0.100,299 = 1.646

Since the calculated t-value (7.905) is greater than the critical t-value (1.646), we can reject the null hypothesis.

We may apply the Pythagorean theorem to calculate the height of the tent, which states that in a right triangle, the square of the hypotenuse (the longest side) is equal to the total of the squares on the other two sides. So, the height of the tent is 8.3077 feet.

In this case, the two sticks form the slanted sides of the tent, and the opening at the bottom forms the base of the triangle. We can consider the height of the tent as the missing side, which is perpendicular to the base.

Let's denote the height of the tent as 'h.' Using the Pythagorean theorem, we have:

(10 ft.)² + (h)² = (13 ft.)²

Simplifying the equation:

100 + h² = 169

Now, subtracting 100 from both sides:

h² = 169 - 100

h² = 69

Taking the square root of both sides:

h = sqrt(69)

Therefore, the height of the tent is approximately 8.3077 feet (rounded to four decimal places).

To determine how long it will take to make 20 slices of toast with the given information, we can analyze the patterns and ratios observed in the data.

From the provided data, we can see that the time it takes to make toast is directly proportional to the number of slices. Specifically, as the number of slices doubles, the time doubles as well.

Using this pattern, we can calculate the estimated time it would take to make 20 slices.

Starting with the given information:

   35 seconds for 4 slices

   70 seconds for 8 slices

   105 seconds for 10 slices

Since the time doubles as the number of slices doubles, we can estimate that it would take approximately 140 seconds for 16 slices (double of 8 slices).

Now, doubling again, we can estimate that it would take approximately 280 seconds for 20 slices (double of 10 slices).

Therefore, it is estimated that it will take around 280 seconds to make 20 slices of toast.

To find the value of x²-5x+3 when x=15-√2, we substitute the value of x into the expression:

x² - 5x + 3 = (15-√2)² - 5(15-√2) + 3

First, let's expand (15-√2)² using the formula for the square of a binomial:

Among the 80 customers, 64 individuals choose to order drinks at the restaurant.

To find the number of people who order drinks at the restaurant, we can start by calculating the percentage of customers who do not order drinks.

Given that 20% of the customers do not order drinks, we can calculate the number of customers who do not order drinks by multiplying 80 (total customers) by 0.20 (20% expressed as a decimal):

Number of customers who do not order drinks = 80 * 0.20 = 16.

Since the total number of customers is 80, and 16 customers do not order drinks, we can subtract the number of customers who do not order drinks from the total number of customers to find the number of customers who do order drinks:

Number of customers who order drinks = 80 - 16 = 64.

A median is a line segment connecting a vertex of a triangle to the midpoint of the opposite side.

The term that describes a line segment connecting a vertex of a triangle to the midpoint of the opposite side is the "median." In triangle geometry, a median is a line segment that joins a vertex of a triangle to the midpoint of the opposite side.

To understand the concept of a median, let's consider a triangle ABC. The midpoint of side BC is denoted as M, and vertex A is connected to M by a line segment. This line segment AM is referred to as the median from vertex A.

Medians have some interesting properties and play a significant role in triangle geometry. Here are a few key characteristics of medians:

1. Medians Divide the Triangle into Two Equal Areas:

Each median of a triangle divides the triangle into two regions with equal areas. The point where all three medians intersect is called the centroid, which is also the center of mass of the triangle.

2. Medians are Concurrent:

The three medians of a triangle are always concurrent, meaning they intersect at a single point called the centroid. This centroid divides each median in a 2:1 ratio, with the longer segment adjacent to the vertex.

3. Medians Divide the Triangle into Six Congruent Triangles:

The medians of a triangle divide the triangle into six smaller congruent triangles. Each of these triangles shares a common vertex with the original triangle.

4. Medians Determine the Centroid:

The centroid of a triangle is the point of intersection of the three medians. It is the balance point of the triangle, where the triangle would perfectly balance on a needle.

In summary, a median is a line segment connecting a vertex of a triangle to the midpoint of the opposite side. Medians have unique properties, including dividing the triangle into equal areas, being concurrent at the centroid, dividing the triangle into congruent triangles, and determining the balance point of the triangle.

log6((2y-3y)/9) = log6(2y/9) - log6(3y/9)

Now, let's simplify each logarithmic expression separately:

For the first term, log6(2y/9), we can write it as:

log6(2y/9) = log6(2y) - log6(9)

For the second term, log6(3y/9), we can write it as:

log6(3y/9) = log6(3y) - log6(9)

Combining these expressions, we have:

log6((2y-3y)/9) = (log6(2y) - log6(9)) - (log6(3y) - log6(9))

Now, let's simplify further by distributing the negative sign:

log6((2y-3y)/9) = log6(2y) - log6(9) - log6(3y) + log6(9)

Notice that log6(9) appears both as a subtraction and addition term. This cancels out, resulting in:

log6((2y-3y)/9) = log6(2y) - log6(3y)

Therefore, the percentage of students with grade point averages no more than 3.36 is approximately 95%.

To determine the percentage of students with grade point averages no more than 3.36 using the empirical rule, we need to calculate the z-score for 3.36 based on the given mean and standard deviation.

The z-score is calculated using the formula:

z = (x - μ) / σ

where x is the value of interest, μ is the mean, and σ is the standard deviation.

In this case, we have:

x = 3.36

μ = 2.52

σ = 0.42

Substituting these values into the formula, we get:

z = (3.36 - 2.52) / 0.42

z = 2

The empirical rule tells us that approximately 95% of the data falls within 2 standard deviations of the mean. Since a z-score of 2 falls within this range, we can conclude that approximately 95% of the students have grade point averages no more than 3.36.

The scale factor and the value of x for each figure is given as follows:

A) Scale factor of 1/3, x = 7 m.

B) Scale factor 0.4747, x = 4.5 in.

For Figure A, we have that the ratio between the areas is given as follows:

510/4590 = 1/9.

As the area is measured in square units, while the side lengths are measured in units, the scale factor is the square root of 1/9, hence it is given as follows:

1/3.

Then the value of x is obtained as follows:

x = 21 x 1/3

x = 7 m.

For Figure B, we have that the ratio between the areas is given as follows:

16/71 = 0.22535.

The scale factor is then the square root of 0.22535, which is given as follows:

0.4747.

Then the value of x is given as follows:

x = 9.5 x 0.4747

x = 4.5 in.

Answer:

(x + 3)(5x + 2) , (2x - 1)(3x + 5)

Step-by-step explanation:

given

A = 5x² + 12x + 6

consider the factors of the product of the x² term and the constant term which sum to give the coefficient of the x- term

product = 5 × 6 = 30 and sum = 17

the factors are + 15 and + 2

use these factors to split the x- term

5x² + 15x + 2x + 6 ( factor the first/second and third/fourth terms )

= 5x(x + 3) + 2(x + 3) ← factor out (x + 3) from each term

= (x + 3)(5x + 2)

then

length = x + 3 , breadth = 5x + 2 or indeed the other way round

-------------------------------------------------------------------------------

given

A = 6x² + 7x - 5

consider the factors of the product of the coefficient of the x² term and the constant term which sum to give the coefficient of the x- term

product = 6 × - 5 = - 30 and sum = + 7

the factors are - 3 and + 10

use these factors to split the x- term

6x² - 3x + 10x - 5 ( factor the first/second and third/fourth terms )

= 3x(2x - 1) + 5(2x - 1) ← factor out (2x - 1) from each term

= (2x - 1()3x + 5)

then

length = 2x - 1 , breadth = 3x + 5 or the other way round

You need to multiply by 5 instead of 6 because each pair of opposite faces on a cuboid has the same area, so by considering one face from each pair, you ensure that you don't count any face twice.

When calculating the total surface area of a cuboid, you need to understand the concept of face pairs.

A cuboid has six faces, but each face has a pair that is identical in size and shape.

Let's break down the reasoning behind multiplying by 5 instead of 6 in the given scenario.

To find the surface area of a cuboid, you can add up the areas of all its faces.

However, each pair of opposite faces has the same area, so you avoid double-counting by only considering one face from each pair. In this case, you have five pairs of faces:

(1) top and bottom, (2) front and back, (3) left and right, (4) left and back, and (5) right and front.

By multiplying the average area of a pair of faces by 5, you account for all the distinct face pairs.

Essentially, you are considering one face from each pair and then summing their areas.

Since all the pairs have the same area, multiplying the average area by 5 gives you the total surface area.

When dividing 150 by 4 (to find the average area of a pair of faces), you are essentially finding the area of a single face.

Then, by multiplying this average area by 5, you ensure that you account for all five pairs of faces, providing the total surface area of the cuboid.

Thus, multiplying by 5 is necessary to correctly calculate the total surface area of the cuboid by accounting for the face pairs while avoiding double-counting.
