In isosceles triangle ABC the segment BD is the median to base line AC. Find BD if the perimeter of the triangle is 50m and the perimeter of ABD is 40 m

Answers

Answer 1

Answer:

BD = 15 m

Step-by-step explanation:

Mathematically, we can find the perimeter of a triangle by adding all of the sides

Mathematically, the line from the top vertix of an isosceles triangle is perpendicular to the base line

So what this mean is that it splits the base line into 2 equal parts

So, in this case, since AC is base;

AD = CD

Please check the attachment for diagrammatic representation

So from the diagram;

25-x + x + BD = 40

25 + BD = 40

BD = 40-25

BD = 15 m

There are a total of 64 students in a drama club and a yearbook club. The drama club has 10 more students than the yearbook club. Write a system of linear equations that represents this situation. Let x represent the number of students in the drama club and y represent the number of students in the yearbook club. How many students are in the drama club? The yearbook club?

Answers

Answer: There are 37 students in the drama club and 27 students in the drama club.

Step-by-step explanation:

Let x= number of students in the drama club.

y= number of students in the yearbook club.

As per given, we have

x+y=64

x=10+y

A system of linear equations that represents this situation:

x+y=64 (i)

x=10+y (ii)

Put value of x from (ii) in (i)

10+y+y=64

⇒ 2y= 54

⇒ y = 27 [Divide both sides by 2]

Put value of y in (ii) , we get

x= 10+27 = 37

Hence, there are 37 students in the drama club and 27 students in the drama club.

Answers

Answer:

width is 11, length is 44

Step-by-step explanation:

width = x

length = y

y= 4x

P = 2x + 2y

110 = 2x + 2(4x)

110 = 10x

x=11

y = 44

The nth term of an AP is 12-4n. Find the first term and the common difference.

Answers

Answer:

the first term is 8 and common difference d is -4.

Step-by-step explanation:

We are given nth term of an arithmetic sequence is: aₙ=12-4n

We need to find first term and common difference of given arithmetic sequence

First term can be found by putting n=1:

[tex]a_n=12-4n\\a_1=12-4(1)\\a_1=12-4\\a_1=8[/tex]

So, first term is a₁= 8

Now to find common difference we need to find second term

Second term can be found by putting n=2

[tex]a_n=12-4n\\a_2=12-4(2)\\a_2=12-8\\a_2=4[/tex]

So, second term is: 4

The common difference is found by subtracting second term with first term: a₂-a₁= 4-8 = -4

So, first term is 8 and common difference d is -4

3. Charlie needs to hire a plumber to fix his kitchen sink. ABC Plumbing charges a flat
fee of $50 plus 535 per hour, Pipes R Us charges a flat fee of $75 and $25 per hour.
How many hours will the two companies charge for the total cost to be equal?

Answers

Answer:

2 hours

Step-by-step explanation:

step one:

given

ABC Plumbing charges

flat fee=$50

charge per hour= $35------------------i want to assume you meant $35 and not $535

Pipes R Us charges

flat fee=$75

charge per hour= $25

Let the number of hours be x

the equation for the charges is given bellow

y=35x+50----------1

y=25x+75-----------2

equating 1 and 2

35x+50=25x+75

35x-25x=75-50

10x=20

divide both sides by 10

x=20/10

x=2 hours

GivenEquation ax² + bx + c = 0One of the roots is twice the otherTo findShow that 2b² = 9acSolution

Let the roots be p and q

The sum and product of the roots:

p + q = -b/apq = c/a

The sum of the roots, considering p = 2q,

p + q = 2q + q = 3q

And

3q = -b/a ⇒ q = -b/(3a)

The product of the roots, considering p = 2q:

pq = 2q(q) = 2q²

And

2q² = c/a

Substitute q with -b/(3a)

2(-b/(3a))² = c/a2b²/(9a²) = c/a2b² = 9a²(c/a)2b² = 9ac

Step-by-step explanation: 5 is the opposite of 4 in this diagram becuase of the bisector so that would make it the same 55.1, while 7 is an obtuse angle so it's clearly more than 90°, leaving 124.9 the most logical explanation.

Statement, ∠3 and ∠6 are supplementary will always be used if lines AB and CD are parallel.

What is a traversal line?

When a line passes through two lines on the same plane, is called traversal line.

Given that,

Two lines are AB and CD,

Also, a transversal line EF intersect line AB and CD.

According to traversal line property,

If two lines are parallel and a traversal line intersect two lines, then each pair of interior angles on the same side of the transversal is supplementary.

In the given figure, Angle 3 and 6 are interior angles

Implies that,

Angle 3 and angle 6 will be supplementary if line AB and CD are parallel.

Hence, statement ∠3 and ∠6 are supplementary shows that lines AB and CD are parallel.

what is the solution set of this inequality? 1<|x-2|<5
(-3, ) U ( , )

Answers

We first need to consider the absolute value of x-2 to find the solution set of this inequality, The solution set of this inequality is (3, 4, 5).

What is absolute value?

An absolute value is a number's distance from 0 on the number line.

Since the inequality is 1<|x-2|<5, we can then determine the two extreme points of the absolute value of x-2.

These points are 1 and 5.

Now, to find the solution set of this inequality, we need to find the two points that are 1 and 5 units away from the point x = 2.

The two points that are 1 and 5 units away from x = 2 are 3 and 5 respectively.

This is because the absolute value of x-2 has two extreme points, which are 1 and 5 units away from the point x = 2.

Therefore, the two points that are 1 and 5 units away from x = 2 are 3 and 5 respectively.
