Answer:
Step-by-step explanation:
1). JL = 36
Reason : Since, PN is the segment joining midpoints of sides JK and LK,
Therefore, JL = 2(PN)
JL = 2(36)
JL = 72
False.
2). ML = 36
Reason: Since, ML = [tex]\frac{1}{2}(JL)[/tex]
ML = [tex]\frac{1}{2}(72)[/tex]
= 36
True.
3). MP = 48.5
Reason : By the same property, MP = [tex]\frac{1}{2}(LK)[/tex]
MP = [tex]\frac{97}{2}[/tex]
MP = 48.5
True.
4). ∠JLK = 102°
Reason: Segment joining midpoints of two sides of a triangle is parallel and measures half of the third side of the triangle.
Since, PM║LK and JL is a transversal line,
∠JMP ≅ ∠JLK [Corresponding angles]
m∠JLK = 102°
True.
5). ∠PNK = 102°
Reason : Since, PN║JL and LK is a transversal line,
∠JLK ≅ ∠PNK [Corresponding angles]
∠PNK = 102°
True.
6). MP║PK
Reason : MP and PK are intersecting each other at P.
Therefore, they can not be parallel.
False.
A large quantity of waste material contains metal. At the successive passes through a recovery
process the mass of the metal recovered is:
32kg at the first pass,
24kg at the second pass;
18kg at the third pass;
13,5kg at the fourth pass, and so on, to form a geometric sequence,
1. How much metal would be recovered at the eighth pass?
(Round off the answer to TWO decimal places)
Answer:
The amount of metal recovered at the eight pass is approximately 4.27 kg
Step-by-step explanation:
The mass of metal recovered formed the following geometric sequence;
32 kg, 24 kg, 18 kg, 13.5 kg
∴ The first term, a = 32 kg
The common ratio in the geometric sequence is found as follows;
r = a·r/a = 24 kg/(32 kg) = 0.75
r = a·r²/a·r = 18 kg/(24 kg) = 0.75
r = a·r³/a·r² = 13.5 kg/(18 kg) = 0.75
The mass of the metal recovered in the eight pass will be the 8th term of the geometric series given as follows;
nth term = a·rⁿ⁻¹
a = 32, r = 0.75, n = 8
∴ 8th term = 32·(0.75)⁸⁻¹ = 32·0.75⁷ = 2187/512 ≈ 4.27
The amount of metal recovered at the eight pass ≈ 4.27 kg.
The eight term of the geometric sequence is 4.27.
Geometric sequenceA geometric sequence is in the form:
aₙ = ar⁽ⁿ⁻¹⁾
where aₙ is the nth term, a is the first term and r is the common difference.
Given that a = 32, r = 24/32 = 0.75
The eight term is a₈ = 32(0.75)⁸⁻¹ = 4.27
The eight term of the geometric sequence is 4.27.

Two angles are complementary. The larger angle is 3 degrees less than twice the measure of the smaller angle. Find the measure of each angle.
Answer:
First angle would be 31°, second angle would be 59°
Step-by-step explanation:
You can use the equation 90° = a + (2a - 3°), where a is the measure of your smaller angle.
simplify:
90° = 3a - 3°
93° = 3a
31° = a
let your second angle equal (2a - 3°)
(2(31°) - 3°) = 59°
Anyone know the correct answer to this?
Answer:
It should be y=4x-7
Step-by-step explanation:
M is the slope meaning Δx over Δy or rise over run
So if you look at (2,2) and count up to (3,6) the rise is 4 and the run is 1 meaning the slope is 4.
B is the y- intercept so then it would just be -7.
9514 1404 393Answer:
y=4x-6
Step-by-step explanation:
The line intersects the y-axis at y=-6, so that is the value of 'b' in the slope-intercept form.
The horizontal difference between marked points is 1 unit; the vertical difference is 4 units. That means the slope is . . .
m = rise/run = 4/1 = 4
Filling in these values (m=4, b=-6), we get ...
y = 4x -6

-3x>15
Answer:
x > -5
Step-by-step explanation:
-3x > 15
divide by -3
x > -5
Answer: x<-5
Step-by-step explanation:
First, we must isolate x in order to graph the inequality properly. To solve for x, you must divide each side by -3. Because you are dividing by a negative number, you must switch the side around. So, the inequality would be [tex]x<-5[/tex]t.To graph this, you must put a veritcal dotted line (since the equation has a less than symbol) and shade to the left (this shows all the possiblilties of what x could be. Or, if you were to graph it on a number line, put an open circle on -5 and draw an arrow left from the dot. Hope this helps!

Answer:
(d) AE = (32√6)/3
Step-by-step explanation:
The side length ratios in a 30-60-90 triangle are 1 : √3 : 2. In a 45-45-90 triangle, they are 1 : 1 : √2.
So, we have the side length ratios ...
CE : CD = 2 : √3
BE : CE = √2 : 1
AE : BE = 2 : √3
Then the ratio AE : CE is ...
[tex]\dfrac{AE}{CD}=\dfrac{2}{\sqrt{3}}\cdot\dfrac{\sqrt{2}}{1}\cdot\dfrac{2}{\sqrt{3}}=\dfrac{4\sqrt{2}}{3}[/tex]
Multiplying by the length of CD, we have ...
AE = (8√3)(4√2)/3
AE = (32√6)/3 . . . . . matches the last choice

The following are the ages (years) of 5 people in a room:
25, 22, 13, 14, 21
A person enters the room.
The mean age of the 6 people is now 22.
What is the age of the person who entered the room?
I
years
Answer:
Step-by-step explanation:
First add all of the numbers together
25+22+13+14+21=82
Now add a variable like X since we don't know the age of the sixth, and divide it by 6 since there are 6 people in the class.
82+X/6=22
(22 is the mean age)
Now solve for the equation
82+X=132
so X =50
Willie runs 4 miles in 28 minutes. If Willie runs at the same rate, how far can he run in 77 minutes?
Answer: Willie runs 11 miles in 77 minutes.
Step-by-step explanation:
To know how many miles he will run in 77 minutes we first need to know how much minutes it takes for Willie to run 1 mile.
28/4 = 7 minutes per mile.
We now want to know how much miles Willie will run if he runs for 77 minutes.
77/7 = 11 miles.
Willie runs 11 miles in 77 minutes.
Answer:
Willie can run 11 miles in 77 minutes
Step-by-step explanation:
I did 28/77 and got 2.75. I then multiplied 2.75 and 4 to get 11.
Therefore, Willie can run 11 miles in 77 minutes.
