Which congruence theorem can be used to prove △abc ≅ △def? aas asa hl sas

Answers

Answer 1

As per the congruence theorem, we have proved that ΔABC ≅ΔDEF.

In math congruence theorem states that if all the three sides of one triangle are equal to all the three sides of another triangle, then both the triangles are congruent to each other.

Here we need to prove ΔABC ≅ΔDEF by using the congruence theorem.

Here we have given that ΔABC and ΔDEF,

=> ∠B≅∠E [right angle]

So, we have obtained that

=> ∠A≅∠D

As we know that there is two angles and one non included side of ΔABC is congruent the two corresponding angles and one non- included side of ΔDEF, therefore, by AAS congruence rule.

So, based on the given fact we have identified that

=> ΔABC ≅ΔDEF

Therefore, the AAS congruence postulate defined that the triangles are congruent if two pairs of corresponding angles and a pair of opposite sides are equal in both triangles.

The answer would be B. (8,4)

That's where the lines overlap

The 8 is counted on the x axis which is the horizontal one of the one laying down because it's 8 across to where the lines overlap

The 4 is counted on the y axis which is vertical or the one standing up. It's 4 because to get to where the lines overlap you'd have to go up 4

Here the correct answer is (8,4) means option B.

Given equations are,

y=x-4 -----------------(1)

y= -0.5x+8-----------(2)

Option A.(4,2): If we put x=4 in equation one then y=0 which does not satisfy equation 2.

Option B.(8,4): If we put x=8 in equation one then y=4 and which satisfies equation 2.

Option C.(2,4): If we put x=2 in equation one then y=-2 which does not satisfy equation 2.

Option D.(4,8): If we put x=4 in equation one then y=0 which does not satisfy equation 2.

Therefore the solution of the equations y=x-4 and y=-0.5x+8 is (8,4) which is option B.

Answers

Answer:

another root=-2,c=-106

Step-by-step explanation:

let q and r be two roots of eqn 10x²-33x-c=0,--(1)

then,q=5.3

comparing eqn--(1) with ax²+bx+c=0,we get

a=10,b=-33,C=-c

Likes hamburgers Does not like hamburgers Total
Likes burritos 39 77
Does not like burritos 95 33
Total 134 205

Part A: What percentage of the survey respondents liked hamburgers but do not like burritos? Show all work. (3 points)

Part B: What is the marginal relative frequency of all customers who like hamburgers? Show all work. (3 points)

Part C: Which category has the lowest joint relative frequency? Show all work. (4 points)

Answers

A: The percentage of respondents who like hamburgers but dislikes burritos is 46.34%

B: Marginal relative frequency  of all who like hamburgers is 0.65.

C:Lowest joint frequency is of the respondents who like both.

What are relative frequencies?

The word "relative" is used to describe how something is being viewed in connection to or in comparison to another event. How frequently an event occurs can be determined by looking at its frequency. On the other hand, relative frequency is a means to compare the frequency of a specific event to all other occurrences.

The ratio of the total number of events occurring in a scenario to the number of times an event occurs is known as relative frequency.

Two facts must be known in order to determine the relative frequency:

>>Number of total events/trials

>>Frequency count for a category/subgroup

Calculation:

                             Like Ham↓  Does Not Like Ham    Total↓

Likes burritos →                 39           38                         77

Does not like burritos →    95           33                        128

Total →                               134           71                        205

So, according to the above table, a total of 77 customers like burritos, out of which 38 do not like hamburgers, hence, the remaining 39 like Hamburgers.

A total of 128 customers do not like burritos, out of which 95 do like hamburgers, hence, the remaining 33 do not like Hamburgers.

A total of 134 customers like hamburgers, but 71 do not like it, hence, the total respondents are 205.

A:

Total people who liked hamburgers are 134 and those who doesnot like burritos and liked hamburgers are 95 and the total people participated in the survey are 205.

So the percentage of people is [tex]\frac{95}{205}*100[/tex] = 46.34%

B:

The marginal relative frequency is nothing but total people who like hamburgers out of the total respondents.. which is

[tex]\frac{134}{205}[/tex] = 0.65

C:

The category that has lowest joint relative frequency is

Case 1:

Likes both burritos and hamburgers:

[tex]\frac{39}{134}=0.29[/tex]

Likes burritos and dislikes hamburgers:

[tex]\frac{38}{71} = 0.53[/tex]

Likes hamburgers and dislikes burritos:

[tex]\frac{95}{134} = 0.71[/tex]

Who dislike both are:

[tex]\frac{33}{71}=0.47[/tex]

So the category which lowest joint frequency is Likes both burritos and Hamburgers.

A: The percentage of respondents who like hamburgers but dislikes burritos is 46.34%

B: Marginal relative frequency  of all who like hamburgers is 0.65.

C:Lowest joint frequency is of the respondents who like both.

What is meant by buoyancy?

The force imposed on a body by a fluid, such as water or air, in which the body is submerged or immersed is known as buoyancy. This force is equivalent to the mass of the fluid that the body has displaced. In mathematics, buoyancy is defined as the sum of the fluid density, gravitational acceleration, and body volume. Archimedes' principle, which asserts that the buoyant force on an item is equal to the weight of the fluid it displaces, is a name for this connection. A key idea in the study of fluid mechanics, buoyancy has many uses, including the construction of boats, planes, and other floating structures.

How to solve?

V = 2/3 * π * r^3,

V = 2/3 * π * 6^3 = 2/3 * π * 216 = 36π.

F = V * d,

F = 36π * 1.35g/c * m^3 = 48.6π g.

Answers

Triangles are shapes that have a total angle measurement of 180°.

To find this answer, add the measures of all the angles and set the equation equal to 180:

(x + 4) + (2x − 11) + (3x + 25) = 180

NOW SOLVE FOR X!

x + 4 + 2x − 11 + 3x + 25 = 180

18 + 6x = 180

6x = 162

x = 27

Now plug 27 into the equation for m∠B:

m∠B = (2x − 11)

m∠B = 2(27) − 11

(a) Find the three consecutive natural numbers whose sum is 66.
(b) Find the three consecutive odd natural numbers whose sum is 39.

Answers

Answer:

(a) 21, 22, 23

(b) 11, 13, 15

Step-by-step explanation:

Natural numbers are the set of numbers 1, 2, 3... Not numbers that we think of as fractions or decimals or negative numbers.

Let x = the first number

Let x+ 1 = the second number

Let  x+ 2 = the third number

x + x+ 1 + x + 2 = 66  Combine like terms

3x + 3 = 66  Subtract 3 from both sides

3x = 63  Divide both sides by 3

x = 21

Check:

21 + 22 + 23 = 66

Let x + the first number

Let x + 2 = the second number

Let x + 4 = the thirds number

x + x + 2 + x + 4 = 39  Combine like terms

3x + 6 = 39  Subtract 6 from both sides

3x = 33  Divide both sides by 3

x = 11

Answers

The account balance(i.e. compound amount) will be $5706.84 after 28 years.

What is daily compounded interest?

Daily compounded interest is defined as an interest that is accrued daily and is computed by charging interest on principal plus interest earned daily. Due to the frequent compounding, daily compounded interest is higher than interest compounded on a monthly or quarterly basis.

Given, Principal = $2834

the annual rate = 2.5% = 0.025

time = 28 years

For compounded daily, n = 365

Now, the compound amount is calculated by

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

or, A = [tex]2834(1 + \frac{0.025}{365} )^{365*28}[/tex]

Answers

The dimensions of a building to be fenced off around a rectangular parcel of land are 10.5 meters and 21 meters.

How come it's called a rectangle?

The Latin word rectus, which meaning "right" or "straight," is the source of the English word "rectangle." The straight sides of a rectangle are a result of its right angles. Rectitude, which refers to moral uprightness, is another term with the same root.

Explanation:

The size of a rectangle

lw = area of rectangle

where,

= length

= width

Thus, perimeter equals 2w plus l.

42 = 2w + l

l = 42 - 2w

Hence,

area = w (42- 2w)

180 = 42w - 2w²

-2w² +42w - 180 = 0

-w² + 21w - 180 = 0

The following is where to find the dimension w;

w = - b / 2a

where

a = -1

b = 21

w = - 21 / 2 × -1

W=10.5 meters.

Then,

l = 42 - 2w

l = 42 - 2(10.5) (10.5)

l=21 meters .Consequently, the measurements are 10.5 meters and 21 meters.

The complete question is added at the end of this solution and as an attachment

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

Length (cm)       Percentage

                          60% of Ehecatl's old hair

                          20% of Ehecatl's old hair

The first step is to determine the length of her hair before she cut it

The equation to calculate the new length of the hair after the cut is represented as

New length = Length of the hair before it was cut * Percentage

Substitute the known values in the above equation

So, we have the following representations

At 60%: 60% x 20 = 12cm

At 20%: 20% x 20 = 4cm

The measure of the given angle ∠BDC or x is 55°.

What are angles?

An angle is a figure in plane geometry that is created by two rays or lines that have a shared endpoint.

The Latin word "angulus," which means "corner," is the source of the English term "angle."

The shared terminus of two rays is known as the vertex, and the two rays are referred to as sides of an angle.

The names of fundamental angles include acute, obtuse, right, straight, reflex, and full rotation.

A geometrical shape called an angle is created by connecting two rays at their termini.

In most cases, an angle is expressed in degrees.

So, we know that:

∠ABC = 80°

∠ABD = 25°

∠BDC = x°

Calculate for ∠BDC:

∠ABC - ∠ABD = ∠BDC

What is Inequality?

A relation by which we can compare two or more mathematical expression is called an inequality.

Given that;

The inequality is,

⇒ y < 2x + 3

Now,

Since, The inequality is,

⇒ y < 2x + 3

Hence, The solution of the inequality is,

For point (- 3,4);

⇒ y < 2x + 3

⇒ 4 < 2 × - 3 + 3

⇒ 4 < - 3

Which is not true.

For point (3,0);

⇒ 0 < 2x + 3

⇒ 0 < 2 × 3 + 3

⇒ 0 < 9

Which is true.

Thus, The solution of the inequality y < 2x + 3 will be;

⇒ (3, 0)

what is the probability that an electron will tunnel through a 0.50 nm air gap from a metal to a stm probe if the work function is 4.0 ev?

Answers

The probability that an electron will tunnel through a 0.50 nm air gap from a metal to a STM probe if the work function is 4.0 eV is 3.4 × 10^-5

The air gap from a metal to a STM = 0.50 nm

The work function = 4.0 eV

The probability is the ratio of the number of favorable outcomes to the total number of outcomes

The probability = Number of favorable outcomes / Total number of outcomes

The value of η = h / [tex]\sqrt{2m(U_0-E)}[/tex]

Substitute the values in the equation

= [tex]\frac{1.05(10^{-34})}{\sqrt{2(9.11(10^{-31})(4(1.6)(10^{-19})} }[/tex]

Do the arithmetic operation

= 0.0972 nm

The probability = exp (-1 / 0.972)

= 3.4 × 10^-5

Therefore, the probability is 3.4 × 10^-5
