Congruent triangles are two triangles with the exact same shape and size.

This means that all of their angles and side lengths are congruent, or equal. In order to determine if two triangles are congruent, we must first make sure that the angles of both triangles are the same.

We can do this by using the Angle-Angle (AA) theorem, which states that if two angles of one triangle are equal to two angles of another triangle, then the two triangles are congruent. The next step is to check that all three side lengths of both triangles are equal.

We can use the Side-Side-Side (SSS) theorem to do this, which states that if all three side lengths of one triangle are equal to the three side lengths of another triangle, then the two triangles are congruent.

Answer:the simplified form of the expression (10x-5/6)-x+4/3 is 9x - 1.

Step-by-step explanation: To simplify the expression (10x-5/6)-x+4/3, you can start by applying the order of operations, which dictates that you should perform operations within parentheses or brackets first.

The expression (10x-5/6) can be simplified as follows:

(10x-5/6) = 10x - (5/6)

= 10x - (5*6)/6

= 10x - 5

= 10x - 5

Next, you can simplify the remaining terms of the expression:

(10x-5) - x + 4/3

= (10x-5) - (x3)/3 + 4/3

= (10x-5) - x + (43)/3

= (10x-5) - x + 4

= 10x - 5 - x + 4

= 10x - x - 5 + 4

= 9x - 1

Therefore, the simplified form of the expression (10x-5/6)-x+4/3 is 9x - 1.

1) Using the common factors of the new area of 12,000 m², the new dimensions of the larger rectangle (lot) are:

2) The percent increase for the length and width are:

The new dimensions of the larger lot are determined as follows:

Length of smaller lot = 80 m

Width of smaller lot = 100 m

Area of smaller lot = 8,000 m² (80 x 100)

The increase in the area of the larger lot = 4,000 m²

The total area of the larger lot = 12,000 m² (8,000 + 4,000)

Remember that area is length x width.

The factors that can result in 12,000 m² when multiplied are 100 m and 120 m, they also meet the requirement for increasing the dimensions by the same amount (20 m).

Length of larger lot = 100 m (80 + 20)

Width of larger lot = 120 m (100 + 20)

Length = 25% (100 - 80)/80 x 100)

Width = 20% (120 - 100)/100 x 100)

An easy definition of a function?

As a set of inputs with one output for each, a function is defined as a relationship between them.

                     In plain English, a function is an association between inputs in which each input is connected to precisely one output.

Let  h(x) = f(g(x))

 Hence,

        h'(x) = f'(g(x) ) . g(x)

  h'(x) = f'g(x)) . g(x)

 Now g(x) is a strictly decreasing function.

Then

  g'(x) < 0 for all real x.

Hence

     h'(x) < 0

The given series is convergent and the first term is 4 and the common ratio is -0.5 and the sum of the series is 8/3 .

The given series is 4 - 4/2+ 4/4 - 4/8 +...

We can see that the first term of the geometric series is 4

Hence a = 4

The second term is  -4/2 and the third term is 4/4

Hence r = 4 ÷ (-4/2) = -4/2 ÷ 4/4 = - 1/2 or -0.5

Since the common ratio is less than 1 we can say that the series is convergent.

Now for a convergent series we know that the sum of the terms of the series is equal to

S = a / (1-r)

or, S = 4 / (1-(-0.5))

or, S = 4 / 1.5

or, S = 8/3

Hence the sum of the convergent series is 8/3 .

Both the ratio test and the root test are based on a comparison with a geometric series and hence function in comparable scenarios.

In fact, if the ratio test works (that is, if the limit exists and is not equal to 1), then so does the root test; the contrary is not true. The root test is thus more broad, although in practise, determining the limit for regularly encountered kinds of series is frequently challenging.

7h25min to min= 445min

3h25min to min= 205min

35600sec to hminsec= 9h53min20sec

Extra Explanation:

To convert hours to minutes, we can multiply the number of hours by the number of minutes in an hour. For example, 7 hours is equal to 7 * 60 = 420 minutes. Similarly, 3 hours is equal to 3 * 60 = 180 minutes.

To convert seconds to hours, minutes, and seconds, we can first convert the total number of seconds to minutes by dividing by the number of seconds in a minute (60). For example, 35600 seconds is equal to 35600 / 60 = 600 minutes. We can then convert the total number of minutes to hours by dividing by the number of minutes in an hour (60). For example, 600 minutes is equal to 600 / 60 = 10 hours. Finally, we can find the remaining minutes and seconds by taking the remainder when the total number of minutes is divided by 60. For example, the remainder when 600 is divided by 60 is 53 minutes. The remaining seconds can be found in a similar manner.

Answer:

7h25mins =445 mins

3h25mins = 205 mins

35600s =9 h 53mins and 20 sec

Step-by-step explanation:

a min equals 60 sec

an hour equals 60 mins

for example 7h equals 60mins ×7

so 420 then add 25 min which then becomes 445 mins

The Coordinates of the centroid of a triangle with the given vertices are (0, 4), (8, 10) and (6, 1) is (14/3, 5) and Centroid of triangle with vertices (1,5),(3,8),(0,2) is (4/3, 5).

The centroid of a triangle is one of the point where all three medians of the triangle intersect. The median is a line segment drawn from one vertex to the midpoint on the opposite side. Triangle centroid divides each median into individual words in a 2:1 ratio. The centroid is usually at 2/3 of the median.

If the three vertices of a triangle are A(x₁,y₁) B(x₂,y₂), C(x₃,y₃), the centroid of the triangle is given by the formula :

G(x₁+x₂+x₃/3, y₁+y₂+y₃/3 ).

We have , two triangles with vertices,

a) triangle whose vertices are A(0, 4), B(8, 10) and C(6, 0). So, the coordinates of the centroid of a triangle whose vertices are (0, 4), (8, 10) and (6 , 1) are ( (0+8+6)/3 , (4+10+1)/3 ) or (14/3, 5).

The probability that a randomly selected person from this sample was a friend of the bride OR of the groom is 0.9875.

Given that, at a wedding each guest asked the 80 guests whether they were a friend of the bride or of the groom.

What is the probability?

Probability can be defined as the ratio of the number of favorable outcomes to the total number of outcomes of an event.

Total Number of Guests which forms the Sample Space, n(S)=80

Let the event (a friend of the bride) =A

Let the event (a friend of the groom) =B

n(A) =59

n(B)=50

Friends of both bride and groom,

So,

n(A∪B)=n(A)+n(B)-n(A∩B)

n(A∪B)=59+50-30

n(A∪B)=79

The number of Guests who was a friend of the bride OR of the groom = 79

Thus,

P(A∪B)=n(A∩B)/n(S)

= 79/80

= 0.9875

Hence, the probability that a randomly selected person from this sample was a friend of the bride OR of the groom is 0.9875.

This means that the length of BD is equal to the length of the altitude from the vertex of the right angle to the hypotenuse. This also means that the length of BD is a right triangle's altitude. In a right triangle, the altitude of a right triangle is the line segment connecting one vertex of the right angle to the hypotenuse, and is perpendicular to the hypotenuse.

[tex]\int\limits {0.5} \, + \frac{6}{(t+4)^{3} } dt[/tex]

[tex]=\int\limits {0.5} \,dt + \int\limits\frac{6}{(t+4)^{3} } dx[/tex]

[tex]=0.5t+\int\limits6u^{-3} du \, \,where \,u=t +4 \, and \, du=dt[/tex]

[tex]=0.5t+6*\frac{u^{-3} }{-2} + C[/tex]

[tex]=0.5t-3u^{-2}+C[/tex]

[tex]=0.5t-3(t+4)^{-2} +C[/tex]

a)  The number of feet that the tree will grow in the second year can be gotten by taking the limit of the integral from  t =1 to t = 2

[tex]\int\limits^2_1 {0.5} \,dt + \int\limits\frac{6}{(t+4)^{3} } dx \, =[0.5t-3(t+4)^{-2} ][/tex]

[tex]=[0.5(2)-3(2+4)^{-2} ]-[0.5-3(5)^{-2} ][/tex]

[tex]=\frac{11}{12}-\frac{1}{2}-\frac{3}{25}[/tex]

[tex]=0.9167-0.5+0.12[/tex]

[tex]=0.5367[/tex]

b)  The number of feet that the tree will grow in the third year can be gotten by taking the limit of the integral from  t =2 to t = 3

[tex]\int\limits^3_2 {0.5} \,dt + \int\limits\frac{6}{(t+4)^{3} } dx \,[/tex]

[tex]=[0.5t-3(t+4)^{-2} ][/tex]

[tex]=[1.5-\frac{3}{49} ]-[1-\frac{1}{12} ][/tex]

=1.439-0.9167

=0.5223 feet

What is probability index?

The present value of benefits for each dollar of investment is calculated using the profitability index approach. In other words, it involves the ratio that is produced by comparing the ratio of the initial investment to the present value of future cash flows from a project.

A solid investment is one with a profitability index of greater than 1.0, with higher values indicating more alluring enterprises.

The ratio between the initial investment and the present value of future cash flows is measured by the profitability index (PI). The index can be used to rate investment projects and display the value produced per investment dollar.

Profitability Index = Present Value of Cash INflows / Present Value of Cash Outflows

Project : Profitability Index

A : 1.8434 (765,000 / 415,000)

B : 1.8043 (415,000 / 230,000)

C : 1.6667 (1200,000 / 720,000)

D : 1.6508 (1560,000 / 945,000)
