The measure of the arc is option (c) 140°

In geometry, an arc is a curved line that is a part of a circle's circumference. The measure of an arc can be calculated using the angle of the arc, which is measured in degrees.

In the case of EBC, the measure of the arc is 140°. This is because we can use the Angle-Side-Angle (ASA) congruence theorem, which states that two triangles are congruent if and only if two angles and the included side are equal.

In the case of EBC, we know that angle A equals 40° and angle C equals 90° so the only variable left is the measure of the arc, which is equal to 140°.

Therefore, the measure of EBC is 140°. This can be verified by drawing the triangle and measuring the arc with a protractor.

Therefore, option (c) is the right one.

The simplified form of sine of x over the quantity 1 plus cosine of x (end quantity)  is 1. Option D

The question can be interpreted as sin(x) / (1 + cos(x))

sin(x) / (1 + cos(x)) = (sin(x) / cos(x)) / (1/cos(x) + cos(x)/cos(x))

                      = tan(x) / (1 + sec(x))

                      = (sin(x)/cos(x)) / (cos(x)/(cos(x)+1))

                      = (sin(x)/cos(x)) / ((cos(x)+1)/cos(x))

                      = sin(x) / (cos(x) + 1)

Therefore, the simplified form of sin(x) / (1 + cos(x)) is:

sin(x) / (1 + cos(x)) = sin(x) / (cos(x) + 1) = 1

Hence, The simplified form of sine of x over the quantity 1 plus cosine of x (end quantity)  is 1

m∠D = 40°, m∠F = 65°, and m∠E = 75°. Round to the nearest degree.

Angel is a geometric figure that can be described as the amount of rotation between two straight line or planes and angles is measured in degree with the full circle being 360°.

To determine the unknown angle measures of △DEF, we can use the fact that the sum of the angles of a triangle is 180°. Thus, if we know two angle measures in the triangle, we can use them to calculate the third.

Let's denote the two known angle measures as m∠D and m∠F. We can use the following equation to solve for the unknown angle measure:

m∠D + m∠F + m∠E = 180°

We can rearrange the equation to solve for m∠E:

m∠E = 180° - m∠D - m∠F

Therefore, once we know the measures of m∠D and m∠F, we can calculate the measure of m∠E.

For example, if m∠D = 40° and m∠F = 65°, then the measure of m∠E would be:

m∠E = 180° - 40° - 65° = 75°

Therefore, m∠D = 40°, m∠F = 65°, and m∠E = 75°. Round to the nearest degree.

Answer:

24km

Step-by-step explanation:

15 min (jogging)

30 min (cycling)

3km/15 min (jogging)

1km/5min (jogging)

4km/5min (cycling)

30÷5= 6

4×6= 24km

Distance covered during riding is 24 km.

Speed of an object is defined as the rate of change of the distance travelled.

Here,

Speed is the distance travelled in a given time.

Total time given, t = 45 minutes

Time taken for jogging, t₁ = 15 minutes

So, time taken for riding, t₂ = t - t₁

t₂ = 45 - 15

t₂ = 30 minutes

Distance covered during jogging, d₁ = 3 km

Therefore speed of jogging, v₁ = d₁/t₁ = 3/15

v₁ = 0.2 km/min

So, speed of riding, v₂ = 4v₁ = 4 x 0.2

v₂ = 0.8 km/min

Therefore distance covered during riding, d₂ = v₂ x t₂

d₂ = 0.8 x 30

d₂ = 24 km

Hence,

Distance covered during riding is 24 km.

There is a solution to the system of equations, and Brianna and Ahmed paid the same price for the items.

What is the system of equations?

A system of equations is a set of one or more equations that are to be solved simultaneously. The solution to a system of equations is the set of values for the variables that satisfy all the equations in the system.

In this case, the system of equations represents the amount that Brianna and Ahmed paid for 5 paintbrushes and 3 art canvases, and 10 paintbrushes and 6 art canvases, respectively. The system of equations is:

5x + 3y = 47 (Brianna's purchase)

10x + 6y = 94 (Ahmed's purchase)

To determine whether Brianna and Ahmed paid the same price for the items, we can compare the value of x and y that satisfy both equations. To do this, we can solve the system of equations using any method we prefer, such as elimination or substitution. Here, we'll use the method of substitution:

From the first equation, we can solve for y in terms of x:

5x + 3y = 47

3y = 47 - 5x

y = (47 - 5x)/3

Substituting this expression for y into the second equation, we get:

10x + 6y = 94

10x + 6((47 - 5x)/3) = 94

Simplifying, we get:

10x + 94 - 10x = 94

94 = 94

This equation is always true, regardless of the value of x.

Therefore, there is a solution to the system of equations, and Brianna and Ahmed paid the same price for the items.

As per the total distance, the distance that Yoni drive on Wednesday is option (c) 5/24 miles.

To find out how far Yoni drove on Wednesday, we must first determine the total distance she drove over the two days.

Tuesday, Yoni drove 1/6 of a mile, which can be expressed as 6/24 of a mile. Wednesday, she drove an additional 9/24 of a mile.

This means that, in total, she drove 15/24 of a mile.

Since we already know that Yoni drove 6/24 of a mile on Tuesday, we can subtract this amount from the total distance she drove over the two days to find out how far she drove on Wednesday.

Subtracting 6/24 of a mile from 15/24 of a mile, we get 9/24 of a mile, which is the distance Yoni drove on Wednesday.

Therefore, Yoni drove 5/24 of a mile on Wednesday

The speed of 50 mph is equivalent to 80.47 km/h.

Mph is an abbreviation for miles per hour, and it is a unit of measurement commonly used in the United States. On the other hand, km/h stands for kilometers per hour, and it is a unit of measurement commonly used in most other countries.

To convert 50 mph to km/h, we need to use a conversion factor that relates the two units.

The conversion factor we need to use in this case is 1 mile = 1.60934 kilometers. This means that for every mile covered, there are 1.60934 kilometers covered. To convert 50 mph to km/h, we simply need to multiply 50 by the conversion factor, as shown below:

50 mph x 1.60934 km/mi = 80.47 km/h

Therefore, 50 mph is equivalent to 80.47 km/h. This means that if you were driving at 50 mph in the United States, you would be traveling at a speed of 80.47 km/h if you were to convert to km/h in another country.

Answer:

x = 3, y = 4

Step-by-step explanation:

3x + y = 13

5x - 2y = 7

To solve by substitution, you solve one of the equations for a variable, and then plug it into the other equation.

I'm going to choose to solve the first equation for y, as that will be the easiest.

y = -3x + 13 (subtract 3x from both sides)

Now we plug this equation into the y in the second equation and solve for x.

5x - 2(-3x + 13) = 7 (distribute)

5x + 6x - 26 = 7 (combine like terms)

11x - 26 = 7 (add 26 to both sides)

11x = 33

x = 3

Now that we know x is 3, we can plug it in a solve either equation for y.

y = -3(3) + 13

y = -9 + 13

y = 4

The inverse of the sine can be calculated by using the formula sin^-1(x) = arcsin(x)

To calculate the inverse sine (sin^-1) of a value, you can use a scientific calculator or look up the value in a trigonometric table. However, if you want to understand how to do it manually, follow these steps:

Make sure the value you are calculating the inverse sine of is between -1 and 1, inclusive. If it is not, the inverse sine is undefined.

Write down the value you want to find the inverse sine of.

Use the formula: sin^-1(x) = arcsin(x), where x is the value you wrote down.

Substitute the value of x into the formula and calculate the inverse sine using a calculator or by using a series expansion or Taylor series approximation.

The inverse sine function returns a value in radians, so you may need to convert it to degrees if that's the unit you're working with.

Out of the given fractions, 9/20, 14/35, and 1/16 are terminating decimals, while 1/35 is a non-terminating decimal.A terminating decimal is a decimal number that ends or terminates after a finite number of digits.

In other words, the decimal representation of the fraction does not go on forever.

To determine if a fraction is a terminating decimal, we need to convert it into a decimal by dividing the numerator by the denominator. If the result is a finite decimal, then the fraction is a terminating decimal; otherwise, it is a non-terminating decimal.

Now, let's apply this method to the fractions given in the question:

9/20: To convert 9/20 into a decimal, we divide 9 by 20, which gives 0.45. Since the decimal terminates after two digits, 9/20 is a terminating decimal.

1/35: To convert 1/35 into a decimal, we divide 1 by 35, which gives 0.02857142857... The decimal goes on forever, so 1/35 is a non-terminating decimal.

14/35: To convert 14/35 into a decimal, we divide 14 by 35, which gives 0.4. Since the decimal terminates after one digit, 14/35 is a terminating decimal.

1/16: To convert 1/16 into a decimal, we divide 1 by 16, which gives 0.0625. Since the decimal terminates after four digits, 1/16 is a terminating decimal.

In summary, out of the given fractions, 9/20, 14/35, and 1/16 are terminating decimals, while 1/35 is a non-terminating decimal.

[tex][T]_{R}[/tex] = Set of all redundancies .

We have been given :

A= Set of every single compound suggestion

R= Logical equivalence of compound propositions .

We need to show that the connection of logical equivalence on the arrangement of all compound propositions is an equivalence connection i.e.R is an equivalence connection .

Then, at that point, we have find the equivalence classes of F and T .

To show that R is an equivalence connection, we need to demonstrate that the connection R is reflexive, transitive and symmetric .

Reflexive

We will let a ∈ A.

As, a compound suggestion is in every case logically comparable to itself .

In this manner, a ≡ a, which suggests that (a,a) ∈ R.

Thus,R is reflexive .

Symmetric

We will let(a,b) ∈ R.

This implies that a ≡ b.

On the off chance that an and b have a similar truth table, b and a have a similar truth table .

Thus, by the evenness of logical equivalences, we get : b ≡ a

which suggests (b, a) ∈ R.

In this way, R is symmetric.

Transitive

We will let (a,b) ∈ R and (b,c) ∈ R.

This infers that :

a ≡ b

b ≡ c .

If an and b have a similar truth table and in the event that b and c have a similar truth table then,a and c

have a similar truth table.

Thus, by transitivity of logical equivalences, we get: a ≡ c

which suggests that (a,c) ∈ R.

Along these lines, R is transitive.

Presently, we can infer that R is an equivalence connection.

Presently, we need to find the equivalence classes of Fand T.

The equivalence class of F has every one of the logical equivalences that are misleading. Also, such logical equivalences are contradictions.

Accordingly,

[tex][F]_{R}[/tex] = Set, everything being equal.

The equivalence class of T have every one of the logical equivalences that are valid. Furthermore, such logical equivalences are redundancies .

Hence,
