A line segment (DE) joining the midpoints of two sides of a triangle is
parallel
to the third sid
Answer:
Given = A △ABC in which D and E are the mid-points of side AB and AC respectively. DE is joined .
To Prove : DE || BC and DE = 1 / 2 BC.
Const. : Produce the line segment DE to F , such that DE = EF. Join FC .
Proof : In △s AED and CEF, we have
AE = CE [∵E is the mid point of AC]
∠AED = ∠CEF[vert. opp.∠s]
and DE = EF [by construction]
∴ △AED ≅ △CEF [by SAS congruence axiom]
⇒ AD = CF ---(i)[c.p.c.t.]
and ∠ADE and ∠CEF ---(ii) [c.p.c.t.]
Now, D is the mid point of AB.
⇒ AD = DB ---(iii)
From (i) and (iii), CF = DB ---(iv)
Also, from (ii)
⇒ AD = || FC [if a pair of alt. int. ∠s are equal then lines are parallel]
⇒ DB || BC ---(v)
From (iv) and (v), we find that DBCF is a quadrilateral such that one pair of opposite sides are equal and parallel.
∴ DBCF is a ||gm
⇒ DF || BC and DF = BC [∵opp side of ||gm are equal and parallel]
Also, DE = EF [by construction]
Hence, DE || BC and DE = 1 / 2 BC
M is the midpoint of LN. What is the measure of LM= 3x and LN= 2x + 2, find LM.
Answer:
LM = 1.5
LN = 3
Step-by-step explanation:
From the question given:
M is the midpoint of LN
LM = 3x
LN= 2x + 2
LM =.?
Next, we shall determine the value of x. This is illustrated below:
Since M is the midpoint of LN, it means that when we divide LN by 2 the result will be LM i.e
LN /2 = LM
With the above formula, we can obtain the value of x as follow:
LN= 2x + 2
LM = 3x
x =..?
LN /2 = LM
2x + 2/ 2 = 3x
Cross multiply
2 × 3x = 2x + 2
6x = 2x + 2
Collect like terms
6x - 2x = 2
4x = 2
Divide both side by 4
x = 2/4
x = 0.5
Finally, we can obtain LM and LN as follow:
LM = 3x
x = 0.5
LM = 3 × 0.5
LM = 1.5
LN= 2x + 2
x = 0.5
LN = 2(0.5) + 2
LN = 1 + 2
LN = 3

Integer Part: 4
Fractional Part: 377
To round 4.377 to the nearest hundredth means to round the numbers so you only have two digits in the fractional part. Use the rule (B) "If the last digit in the fractional part of 4.377 is 5 or more and the second digit in the fractional part is less than 9, then add 1 to the second digit of the fractional part and remove the third digit." With 4.377, rule B applies and 4.377 rounded to the nearest hundredth is: 4.38

A wall Of a building is 34 inches wide, 14 inches is concrete, 12 inches is brick, and 8 inches is limestone. what fraction of the wall is brick?
Step-by-step explanation:
It is given that,
A building is 34 inches wide. Its 14 inches is concrete, 12 inches is brick, and 8 inches is limestone. We need to find the fraction of the wall is brick.
A fraction is in the form of x/y. y is total value and x is a part of y.
Here, 12 inches is brick. So, its fraction is :
[tex]F=\dfrac{12}{34}=\dfrac{6}{17}[/tex]
So, fraction of [tex]\dfrac{6}{17}[/tex] is the wall which is brick.
find the exact value of cosine theta given that sin theta equals -12/13 and theta is in the quadrant three
Answer:
cos θ = -5/13
Step-by-step explanation:
sin θ = -12/13
Use Pythagorean identity.
sin²θ + cos²θ = 1
(-12/13)² + cos²θ = 1
144/169 + cos²θ = 1
cos²θ = 25/169
cos θ = ±5/13
θ is in the 3rd quadrant, so cos θ < 0.
cos θ = -5/13

Answer:
2.48×10^13 miles
Step-by-step explanation:
There are about (365.25 days)(86400 seconds/day) = 31,557,600 seconds in one year. There are 1609.344 meters in one mile. So, the conversion can be written as ...
(4.22 ly) (3×10^8 m/s) (3.15576×10^7 s/yr) / (1.609344×10^3 m/mi)
= 4.22×3×3.15576/1.609344×10^(8+7-3) mi
≈ 24.8×10^12 mi
4.22 light years is about 2.48×10^13 miles
round 24.927 in two decimal places.
Answer:
24.93
Step-by-step explanation:
Rounding to two decimal places is the same as rounding to the nearest hundredth.
Locate the hundredth:
24.927
Check the number to the right of it:
24.927
If the number is greater than or equal to 5, then we round up. If the number is less than or equal to 4, we round down.
7 is greater than 5. So, we round up.
24.927 ≈ 24.93
2.94 is the answer.
What are the places in a decimal?The first digit after the decimal represents the tenth place. the subsequent digit after the decimal represents the hundredth area. The closing digits retain to fill within the vicinity values till there are no digits left.
What does preserving 2 decimal places suggest?Rounding a decimal quantity to two decimal locations is the same as rounding it to the hundredth place, that's the second area to the right of the decimal factor. as an instance, 2.83620364 may be spherical to two decimal locations as 2.94, and 0.7035 can be spherical to 2 decimal places as zero.70.

*need fast answer please * What are some numbers of pushups that Bucky will never do in any game ?
Answer:
{1, 2, 4, 5, 6, 8, 10, 11, 12, 14, 15, 16, 19, 20, 23, 24, 25, 27, 28, 29, 31, 32, 33, 35, 36, 37, 39, 40, 41, 43, 44, 47, 48, 51, 52, 55, 56, 59, 60, 64, 68, 72, 74, 76, 78, 80, 82, 86, 90, 94, 98}
Step-by-step explanation:
The total number of pushups Bucky does is the sum sequence of scores in the game. The values in that sequence depend on the order of the goal types.
For example, consider a 2-goal game. Possible sequences of scores are ...
3, 6 (9 pushups)
3, 10 (13 pushups)
7, 10 (17 pushups)
7, 14 (21 pushups)
You can see that for a 1- or 2-goal game, the number of pushups cannot be any of ... 1, 2, 4, 5, 6, 8, 10, 11, 12, 14, 15, 16.
The list above is all of the numbers less than 100 that are numbers of pushups Bucky will never do in any game in which the goal values are either 3 or 7.
__
Any game with 8 goals or more will have numbers of pushups more than 100.

or simplicity, let X=M G = 1 I = 2 if you like decimals C = 3 + 0.75Y or if you prefer fractions C = 3 + 3/4Y the simple multiplier is equal to
Answer:
the simple multiplier is equal to 4
Step-by-step explanation:
Given that:
Y= C + I + G + (X - M)
the average expenditure Y must be equal to the totality of the output
If C = 3 + 0.75Y
here;
the marginal propensity consumed MPC = 0.75
Then,
Y = 3 + 0.75Y + 2 + 1
Y = 6+0.75 Y
Y - 0.75 Y = 6
0.25 Y = 6
Y = 6/0.25
Y = 24
However, the simple multiplier can be expressed as:
[tex]= \dfrac{1}{1-MPC}[/tex]
[tex]= \dfrac{1}{1-0.75}[/tex]
= [tex]\dfrac{1}{0.25}[/tex]

Three white balls and three black balls are distributed in two urns in such a way that each contain three balls. We say that the system is in state i, i=0,1,2,3, if the first urn contains i white balls. At each step, we draw one ball from each urn and place the ball drawn from the first urn into the second, and conversely with the ball from the second urn. Let Xn denote the state of the system after the nth step. Explain why {Xn, n=0 ,1, 2} is a Markov chain and calculate its transition probability matrix.
Answer:
Following are the answer to this question:
Step-by-step explanation:
In-state 0, it has urns of the 100% chance of shifting towards state 1 because a colored ball must be substituted.
In the [tex]state 1: \frac{1 \ white}{2 \ black} \ \ \ and \ \ \frac{2 \ white}{1 \ black}[/tex]
The probability to select White from both the probability to select Black from both are 2/9, therefore there are 4/9 possibilities to remain in State 1.
It is probable which white from both the beginning is selected and black from the second, so that 1/9 probability of 0.
The probability is 4/9 that the first black and the second white will be chosen and 4/9 possibility will be made to state 2.
In the [tex]state 2: \frac{2 \ white}{1 \ black} \ \ \ and \ \ \frac{1 \ white}{2 \ black}[/tex]
This is essentially a state 1 mirror image because identical claims are used for reverse colors.
In-State 3, the urns are 100% likely to revert to State 2.
It is the representation of matrix M is, therefore:
[tex]( ..0. ..1. ..0. ..0. )\\\\( \frac{1}{9} \frac{4}{9} \frac{4}{9}.. 0. )\\\\( ..0. \ \frac{4}{9} \ \frac{4}{9} \ \frac{1}{9})\\\\( ..0. ..0. ..1. ..0. )\\\\So, \\ X_n = M \times X_{n}-1 \\\\Or\\X_n = M^n \times X_0[/tex]

The graph of a sinusoidal function intersects its midline at (0,2) and then has a minimum point at (3,-6) Write the formula of the function, where x is entered in radians.
Answer:
f(x)=-8sin(pi/6x)+2
Step-by-step explanation:
The graph of a sinusoidal function intersects its midline at (0,2) and then has a minimum point at (3,-6) So, the function is f(x) = -8sin(pi/6x)+2.
What is the sinusoidal function?The sinusoidal function has the following form:
[tex]y = x_0 + A\: sin(w.x+\theta)[/tex]
Where:
A= Amplitude
w = Angular frequency
[tex]x_0[/tex] = Independent component of the midpoint value
[tex]\theta[/tex] = Phase angle
Amplitude is the absolute value of the difference between a dependent component of the midline and the absolute minimum
A = |-6 - 2|
A = 8
[tex]x_0[/tex] = 2
The angular frequency of the function is now determined by substituting all remaining variables and clearing it within the sinusoidal function
[tex]w.x + \theta = \pi / 6[/tex]
