Answer:
La Comunidad A deberá aportar $60,000, la Comunidad B deberá aportar $120,000 y la Comunidad C deberá aportar $180,000. Cada Comunidad aportará $500 por persona.
Step-by-step explanation:
Dado que la obra de drenaje tiene un costo de materiales de $360,000, y que dicho costo será soportado por cada comunidad en proporción a sus habitantes, sabiendo que en la comunidad A hay 120 habitantes; en la comunidad B 240 y en la comunidad C 360, para determinar con cuánto dinero debe cooperar cada una se debe realizar el siguiente cálculo:
120 + 240 + 360 = 720
C = 1/2 x 360,000 = 180,000
B = 1/3 x 360,000 = 120,000
A = 1/6 x 360,000 = 60,000
Así, la Comunidad A deberá aportar $60,000, la Comunidad B deberá aportar $120,000 y la Comunidad C deberá aportar $180,000.
A su vez, la aportación por persona en las tres comunidades surge del siguiente cálculo:
360,000 / 720 = 500
Así, cada comunidad aportará $500 por persona.

Is F={56,777,1,2} a subset of G={2,78,64,333,1,7,56,77,900}?
Answer:
No
Step-by-step explanation:
F is not a subset of G because not every element in F lives in G. Even through 56, 1 and 2, all live in G, and are elements of F, 777 is an element of F but is not an element of G.
(If there is a typo, and every element in F is in fact an element in G, then the answer would be yes, F is a subset of G)
We can see that element 777 is not in set G. Hence the set F is not a subset of set G.
A set is a collection of elements not necessarily arranged in a particular pattern.For a set A to be a subset of another set B, all elements of the set must be found in set B.For the given set F={56,777,1,2}, we can see that the element 777 is not in the set G. Hence the set F is not a subset of set G.

Sam can ride his bike 4.2 kilometers in 6 minutes. Amanda can ride her bike 3.2 kilometers in 8 minutes. Jesse can ride his bike 3.0 kilometers in 5 minutes.
Which rider might go farther in 1 minute?
Answer:
jesse or sam i think its sam by a little bit.
Step-by-step explanation:
Answer:
Sam
Step-by-step explanation:
Find all of their speeds to find how far they will go in 1 minute, by dividing the number of kilometers by the number of minutes:
Sam
4.2/6
= 0.7 km/min
Amanda
3.2/8
= 0.4 km/min
Jesse
3/5
= 0.6 km/min
Since 0.7 is the greatest number, that means Sam is the rider that will go the farthest in one minute.

Four different mathematics books, six different physics books, and two different chemistry books are to be arranged on a shelf. How many different arrangements are possible if a) The books in each particular subject must all stand together b) Only the mathematics books must stand together
Answer:
a) 207,360 ways
b)8,709,120 ways
Step-by-step explanation:
Total number of subjects= 3
Number of mathematics books = 4
Number of physics books = 6
Number of chemistry books = 2
Part a:
Number of possible arrangement s= 3! 4! 6! 2!= 6*24*720*2= 207360 ways
In this we have included 3! because the books have to be placed in such a manner that the books in each particular subject must all stand together.
Part b:
Similarly the mathematics books must stand together so they are treated as
The total number of books will be
Physics books + Chemistry books+ Mathematics books= 6+2+1(treated as single) = 9
But there are 4 different mathematics books so these can be arranged in 4 ways.
Total number of ways in which these books can be arranged = 9! 4!= 8709120 ways.

Answer:
D
Step-by-step explanation:
A, B, and C are not linear functions
D would be y=x/2
If you graphed y=x/2, you would get the points (4, 2), (7, 3.5), (8, 4), and (10, 5)
It's more obvious if you notice that y is half of x.
solve for x 0.72= 0.4( x 1.4)

What is 1092 using the polynomial identity (a+b)2=a2+2ab+b2 ?
Drag and drop the correct responses into the boxes.
Let the smaller value a = Response area and the larger value b = Response area. Then a2+2ab+b2 is Response area. This can be simplified to Response area. So, 1092 is equal to Response area.
Answer:
Step-by-step explanation:
The fill ups is
Smallest number, a= 9
Largest number, b= 100
a²+ 2ab+ b² can be written as 9²+ 2. 9. 100 + 100²
What is Polynomial?A polynomial is a mathematical equation that solely uses the operations addition, subtraction, multiplication, and non-negative integer exponentiation of variables. Variables are sometimes known as indeterminates in mathematics.
Given:
Here the smallest number can be taken as 9.
and, here we have 109² then the number can be split as 100 + 9.
Thus, the largest number is 100.
Now, a²+ 2ab+ b² can be written as 9²+ 2. 9. 100 + 100² which can be simplified as 11881.
