The measure of angle ADC in the geometric system is equal to 55°.

In this question we find a geometric system formed by a quadrilateral and an angle vertical to a vertex of the quadrilateral. Angle CDE is supplementary to angles EDF and ADC. Two angles are supplementary whose sum of measures equals 180°. Therefore:

m ∠ CDE + m ∠ EDF = 180°

(2 · x + 1) + (x - 7) = 180°

3 · x - 6 = 180°

3 · x = 186°

x = 62

m ∠ CDE = 2 · x + 1

m ∠ CDE = 2 · 62 + 1

m ∠ CDE = 125°

m ∠ ADC = 180° - 125°

m ∠ ADC = 55°

The required order from least to greatest is √3 − 1, 2√10 ÷ 5, √14, 3√2, √19 + 1 and 6

An arrangement of numbers in which the numbers are arranged from smallest to greatest numbers is called ascending order.

Given that, some numbers, 3√2, √3 − 1, √19 + 1, 6, 2√10 ÷ 5 and √14.

We need to order them from least to greatest,

3√2 = 4.24

√3 − 1 = 0.73

√19 + 1 = 5.35

6

2√10 ÷ 5 = 1.26

√14 = 3.74

The order from least to greatest is :-

0.73, 1.26, 3.74, 4.24, 5.35 and 6

i.e.

√3 − 1, 2√10 ÷ 5, √14, 3√2, √19 + 1 and 6

Hence, the required order from least to greatest is √3 − 1, 2√10 ÷ 5, √14, 3√2, √19 + 1 and 6

The value of the tax for the meal is $1.05.

The government levies a consumption tax known as a sales tax on the purchase of goods and services. At the point of sale, a standard sales tax is imposed, collected by the shop, and paid to the government.

Depending on the regulations in that country, a business may be responsible for sales taxes in that jurisdiction if it has a presence there, which can be a physical site, an employee, or an associate.

Given the  cost of the meal = $15.00

and rate of tax = 7%

converting the rate of tax into decimal form,

rate of tax = 7% = 7/100

rate of tax = 0.07

amount of tax = cost x rate of tax

amount of tax = 15 x 0.07

amount of tax = $1.05

Hence the amount of tax is $1.05.

The statement about function g which is true is that: function g is exponential because g(x) changes by equal factors over equal intervals of x.

The slope of a line simply refers to the gradient of a line and it's typically used to describe both the ratio, direction and steepness of an equation of a straight line.

Mathematically, the slope of a straight line can be calculated by using this formula;

\(Slope = \frac{Change\;in\;y\;axis}{Change\;in\;x\;axis}\\\\Slope = \frac{y_2\;-\;y_1}{x_2\;-\;x_1}\)

Slope = (40 - 10)/(2 - 1)

Slope = 30/1

Slope = 30

Slope = (160 - 40)/(3 - 2)

Slope = 120/1

Slope = 120.

Factor = 40/10 = 4

Factor = 160/40 = 4

Factor = 640/160 = 4.

The term n is the initial amount that the television is to be sold.

We are told that the television in this case is to be sold at a discount piece. The implication of this is that there is something that has to be removed from the price of the television as it is sold.

We are told that what they are to remove from the price of the television is about $75  and that when this is done, the price of the television would be about $300. Thus n is the original price of the television.

The variable n represents the initial value of the television

From the question, we have the following parameters that can be used in our computation:

Amount off = $75

New price = $300

When represented as the equation, we have

n - 75 = 300

Add 75 to both sides of the equation

So, we have the following representation

n = 375

Step-by-step explanation:

To find the least common denominator (LCD) of 2/3 and 2/10, determine the smallest common multiple of the denominators.

The prime factorization of 3 is 3, and the prime factorization of 10 is 2 * 5.

To find the LCD, we take the highest power of each prime factor that appears in either denominator:

Therefore, the LCD is  2 * 3 * 5 = 30.

The volume of the solid of revolution is \(\frac{16\pi}{3}\) cubic units.

First, we determine the limits between the two curves. (\(f(x) = 4\cdot x -2\), \(g(x) = x^{2}+1\))

\(f(x) = g(x)\) (1)

\(4\cdot x - 2 = x^{2}+1\)

\(x^{2}-4\cdot x +3 = 0\)

\((x-1)\cdot (x-3) = 0\)

The lower and upper bounds are 1 and 3, respectively. It is to notice that \(f(x) > g(x)\) for \(x \in (1, 3)\). Thus, we determine the volume of the solid of revolution by shell method, that is to say:

\(V = 2\pi \int\limits^a_b {x\cdot |f(x) - g(x) |} \, dx\) (2)

If we know that \(a = 3\), \(b = 1\), \(f(x) = 4\cdot x - 2\) and \(g(x) = x^{2}+1\), then the volume of the solid of revolution is:

\(V = 2\pi \int\limits^3_1 {|4\cdot x^{2}-2\cdot x -x^{3}-x|} \, dx\)

\(V = 2\pi\int\limits^3_1 {(4\cdot x^{2}-x^{3}-3\cdot x)} \, dx\)

\(V = 8\pi \int\limits^3_1 {x^{2}} \, dx - 2\pi \int\limits^3_1 {x^{3}} \, dx -6\pi \int\limits^3_1 {x} \, dx\)

\(V = 8\pi\cdot \left(\frac{3^{3}}{3}-\frac{1^{3}}{3} \right)-2\pi \cdot \left(\frac{3^{4}}{4}-\frac{1^{4}}{4} \right) - 6\pi\cdot \left(\frac{3^{2}}{2}-\frac{1^{2}}{2} \right)\)

\(V = \frac{208\pi}{3} - 40\pi -24\pi\)

\(V = \frac{16\pi}{3}\)

Answer:

P(A|B) = 0.5

Step-by-step explanation:

A: set of prime numbers ={1,2,3}

B: set of divisors of 3 ={1,3}

P(A)=P(1)+P(2)+P(3)= 0.1+0.1+0.3 =0.5

P(B)=P(1)+P(3)=0.1+0.3=0.4

P(A|B) means: probability of A knowing that B

In other words we have to find the probability that a prime outcome occurs knowing that it is a divisor of 3

Its formula is given by:

P(A|B) = P(AintersectionB) /P(B)

A intersection B: outcome is prime and a divisor of 3 at the same time. (common elements between sets A and B)

A int B= {1,3}

P(AintB)= P(A)xP(B) = 0.5x0.4=0.2

P(A|B) =P(AintB) / P(B)

Answer:

The volume of the hemisphere is 1,475.73 cm³.

Step-by-step explanation:

Given that a hemisphere is half a sphere, to determine the volume of a hemisphere with a diameter of 8.9 cm, the following calculation must be performed, knowing that the volume of a sphere is equal to 4/3 πr³, and the radius is half the diameter:

8.9 x 2 = 17.8 / 2 = 8.9

(4/3 x 3.14 x 8.9³) / 2 = X

(1.333 x 3.14 x 704.969) / 2 = X

(4.18666 x 704.969) / 2 = X

2,951.47 / 2 = X

1,475.73 = X

Therefore, the volume of the hemisphere is 1,475.73 cm³.
