Answer:
Step-by-step explanation:
Permutation and combination is very important in our daily life. By using it, we can already distinguish or identify the different possible ways of the things that we get or have.
Permutation refers to the different possible arrangements of a set of objects and order is very important while combination is the number of ways of selecting from a set when the order is not important.
Which of the following situations does NOT illustrate combination?
a. Selecting 2 songs from 10 choices for an audition piece
b. Fixing the schedule of a group of students who must take exactly 8 subjects
c. Enumerating the subsets of a set
d. Identifying the lines formed by connecting some given points on a Plane
In this situations, we can determine if it is all combination or not. Let's find it out.
a. Selecting 2 songs from 10 choices for an audition piece - this situation does not require any order or arrangement. That's why letter A illustrates combination.
b. Fixing the schedule of a group of students who must take exactly 8 subjects - in fixing and arranging the schedule of a group of students, it must have to be in order so that they can determine their subjects every hour or period and everyday. The schedule must be arrange properly so that the students must not get confused. That's why in this situation the order and arrangement is very important and it shows the concept of permutation not combination.
c. Enumerating the subsets of a set - in enumerating we are not required to make it in order. We can list the subsets of a set in any order, that's why letter C illustrates combination.
d. Identifying the lines formed by connecting some given points on a Plane - we can connect different and many given points in any directions to have a Plane. It is not required to connect all the points in order so that we can form a Plane. Also, in identifying the lines, we can write and list it in any order and that the order is not important.
In conclusion, the situation that does NOT illustrate combination is situation B, because it is more on the concept of permutation not in combination.

Mr.Jones has 160 animals on his farm.of these animals,20% are cows,30% are goats,10% are horses, and the rest are chickens.
Answer:
There are 64 chickens
Step-by-step explanation:
60% of the animals were not chickens so I found 60% of 160 which is 96, and then I subtracted 96 from 160 and got 64
Please mark brainlest for my overcomplicated description of math
Answer:
16 horses
32 cows
48 goats
64 chickens
Step-by-step explanation:
total animals = 160
⇒ 10% of animals = 160/10 = 16
⇒ 20% = 16 x 2 = 32
⇒ 30% = 16 x 3 = 48
16 horses
32 cows
48 goats
chickens = 160 - 16 - 32 - 48 = 64

Casey constructed this figure by using a compass and a straightedge to draw circle O and diameter PQ. She then used a compass to draw two arcs. She labeled the points where those arcs intersect the circle M and N, and she drew the chords that form the triangle.
If ΔMNP is equilateral, how did Casey draw the arcs that defined points M and N?
A.
She used a compass centered at P with a radius set equal to PQ.
B.
She used a compass centered at O with a radius set equal to PO.
C.
She used a compass centered at Q with a radius set equal to PO.
D.
She used a compass centered at P with a radius set equal to (PQ).
E.
She used a compass centered at Q with a radius set equal to PQ.
Answer:
D) she used a compass at P with a radius set equal to 3/4(PQ)
Step-by-step explanation:
Step 1
She used a compass at P with a radius set equal to 3/4PQ .
Step 2
Since if ∆MNP is equilateral triangle so, PM=PN=MN
Since O is center then PO=OQ
And let R is the mid point of MN.
So, R is also mid point of OQ.
Hence, she used a compass at P with a radius set equal to 3/4(PQ)

PLS ANSWER ASAP! Enter the equation of the line in the form y=mx Where m is slope
Answer:
Well technically its inf due to the arrow, there are no points showing where to start from and where to end
the way you do it it you just count the amount of units it goes up, in this case for every square its going up 5 units, once you get that number you put that on top of your fraction, then you go over on the x axis till you hit your line (x axis is going by 10 every time). This would be your number on the bottom of the fraction.

If 4 lattes cost 15 dollars how much would 6 caffe lattes cost?
PLEASE HELP
Answer:
The lattes would cost about 22.50
Step-by-step explanation:
In order to figure out how much 6 lattes cost we need to know how much 1 is.
So you take 15 divided by 4 which gets you 3.75
Then you take 3.75 and times it by 6. Getting you the answer of 22.50
Answer:
$22.5
Step-by-step explanation:
It would be 22.5$ because if lattes cost 15$ then we need to find the cost of 1.
To do this by we divide 15 by 4.
3.75
4{15}
-0
___
15
- 12
--------
3 so because there is 3 left of 4 is is .75 because it couldn't make it to 4
so since 1 latte cost 3.75$ we times 3.75 by 6 latte.
Here are 3.75 times numbers 1-6.
3.75 x 3=11.25
3.75 x 4=15
3.75 x 5=18.75
3.75 x 6=22.5 and there's your answer,you get 6 lattes for 22.5$ or 22$ and 50 cents.

Step-by-step explanation:
Create a linear equation for line AB and line CD
Find slope using slope formula [tex]m=\dfrac{y_2-y_1}{x_2-x_1}[/tex]
then use point-slope form of linear equation [tex]y-y_1=m(x-x_1)[/tex]
(where m is the slope and [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex] are two points on the line)
Line AB
[tex]m=\dfrac{-16+1}{-8+20}=-\dfrac54[/tex]
[tex]\implies y+1=-\dfrac54(x+20)\\\\\implies y=-\dfrac54x-26[/tex]
Line CD
[tex]m=\dfrac{0+11}{-19+9}=-\dfrac{11}{10}[/tex]
[tex]\implies y+11=-\dfrac{11}{10}(x+9)\\\\\implies y=-\dfrac{11}{10}x-\dfrac{209}{10}[/tex]
To find the point of intersection, equate the equations and solve for x::
AB = CD
[tex]\implies -\dfrac54x-26=-\dfrac{11}{10}x-\dfrac{209}{10}[/tex]
[tex]\implies -\dfrac{3}{20}x=\dfrac{51}{10}[/tex]
[tex]\implies x=-34[/tex]
Substitute found value of x into one of the equations and solve for y:
[tex]y=-\dfrac54(-34)-26=\dfrac{33}{2}[/tex]
Therefore, point of intersection is [tex]\left(-34, \dfrac{33}{2}\right)[/tex]

and what is 2.4 is 5% of what number
Answer:
60% of 25 = 15 and 2.52
Step-by-step explanation:
Answer:
60% of 25 should be 15.
for question 2: its 48
Step-by-step explanation:
1) 2.4 = 5% × Y
STEP 2: 2.4 = 5/100 x Y
Multiplying both sides by 100 and dividing both sides of the equation by 5 we will arrive at:
STEP 3 Y = 2.4 × 100/5
STEP 4) Y = 2.4 × 100 ÷ 5
STEP 5) Y = 48
Finally, we have found the value of Y which is 48 and that is our answer.

D .Counterclockwise 270-degree rotation
Answer:
B. Clockwise 270-degree rotation
Answer:
B) Clockwise 270-degree rotation
Step-by-step explanation:
Clockwise motion is in the same direction as a clock's hands: from the top to the right, then down and then to the left, and back up to the top. The opposite motion is counterclockwise.
From inspection of the diagram, we can see that the curved dotted line (which shows the direction of motion) is suggesting a clockwise motion.

The picture represents a hippo pool surrounded by a park.
The two pentagons are similar with AB = 3 CD and the area
of the park is 2,700sq.m Find the area of the pool?
Given that the two pentagons are similar figures, the area of the pool = 675 sq. m..
What is the Area of Similar Figures?If two figures are similar to each other, then, the ratio of the square of their corresponding sides equals the ratio of their areas.
We are given that the pool and the park are similar to each other. The diagram given is missing, however, here's how to find the area of the pool:
If x is a side of the pool and y is the corresponding side length of the park, therefore:
area of pool/area of park = x²/y².
Plug in the values given, cross multiply and find the area of the pool.
For example, if 3 is a side of the pool = x
6 is corresponding side of the park = y
Area of park = 2,700 sq. m
Thus:
Area of pool/2,700 = 3²/6²
Area of pool/2,700 = 9/36
Area of pool = (9 × 2,700)/36
Area of pool = 675 sq. m.
