Literally find the common denomiator. That's the first step for any of these computational fraction problems.
Here are the following denomiators: 4,8,3,6. You notice that 24 is a multiple of all the numbers. Thus, our common denomiator is 24. Next we change each fraction based on our new denomiator
3/4 = 18/24
5/8 = 15/24
2/3 = 16/24
1/6 = 4/24
Now we do basic computation
18/24 + 15/24 + 16/24 - 4/24 = 45/24 = 15/8
is -9 irrational or rational
Answer:
Rational because it's a whole number

Step-by-step explanation:
To build a deck, Roberto needs to buy 180 screws (s), 9 posts (p), and 36 pieces of 1" by 6" lumber (l). He already had the rest of the materials for the deck that he needs. An expression that represents his purchases is shown below:
180s + 9p + 36l
Part A:
Factor the expression that represents Roberto's purchases.
Part B:
The costs of buying the deck materials are shown in the chart below:
Material Cost
100 screw container $6.99
1 post $16.40
Set of 10 pieces of lumber $88.20
What materials does Roberto need to buy?
Part C:
What is the total cost to buy the deck materials (excluding tax)?
The total cost of materials can be found from a list of materials based on the market unit rate.
The correct responses are;
Part A: The factored expression is; 9 × (20·s + p + 4·l)Part B: The materials to be bought are; 2 cartons of screws, 9 pieces of posts, and 4 sets of 10 pieces of lumber.Part C: The total cost of materials is $514.38.Reasons:
Part A: The given expression representing the purchase is presented as follows;
Purchases = 180·s + 9·p + 36·l
Where;
s = Screws
P = Posts
l = Lumber
The factored expression is found as follows;
Purchases = 180·s + 9·p + 36·l = 9 × 20·s + 9·p + 9 × 4·l, which gives;
180·s + 9·p + 36·l = 9 × (20·s + p + 4·l)
The factored expression is; 9 × (20·s + p + 4·l)
Part B: The costs are;
100 screws = $6.99
1 posts = $16.40
10 pieces of lumber = $88.20
The materials Roberto need to buy are;
180 screws, which can be obtained by buying 2 cartons of screws.
9 posts, which is obtained by buying 9 pieces of posts.
36 lumber which can be obtained by buying 4 × 10 pieces = 40 pieces of lumber.
Therefore, the, material Roberto needs to buy are;
2 cartons of screws
9 pieces of posts
40 pieces of lumber
Part C: The total cost of the materials are therefore;
2 cartons of screws × $6.99 per carton = $13.98
9 pieces of posts × $16.40 per piece = $147.6
4 Sets of 10 pieces of lumber × $88.20 per set = $352.8
The total cost = $13.98 + $147.6 + $352.8 = $514.38

A research group is interested in gauging perceptions about costs of textbooks among college students. They use an alphabetized list of students in state universities and use technology to generate a randomly shuffled list of students. They then select students to contact from this list until they have succeeded in contacting 175 students. What is the population parameter of interest
Answer:
Cost of textbooks
Step-by-step explanation:
The population parameter refers to any numerical messure derived from using the entire population data. Since the study above looks to evaluate how college students view the cost of books. Since the population of interest is all students, the reason for which the entire population of students are employed and the variable that is to be measured using these population of student is called the population parameter. In the other hand, numeric estimates or observations derived from a portion of the population called the sample is refereed statistic.

Each side of a pentagon is 20 inches longer than the previous side. What is the length of the shortest side is the perimeter is 401 inches?
Answer:
40.2
Step-by-step explanation:
Side 1= x
Side 2= x+20
Side 3= x+40
Side 4= x+60
Side 5= x+80
Total perimeter= 401
x+x+20+x+40+x+60+x+80= 401
Simplify it...
5x=201
x= 40.2
This is the answer= 40.2
Please award me brainliest!
Thanks!
The length of the shortest side of the pentagon would be:
40.2
Find the lengthGiven that,
Every side of a pentagon is longer by 20 inches.
No. of sides in pentagon = 5
So,
Ist side of the pentagon [tex]= x[/tex]
IInd Side of the pentagon [tex]= x + 20[/tex]
IIIrd Side of the pentagon [tex]= x + 40[/tex]
IVth Side of the pentagon [tex]= x + 60[/tex]
Vth Side of the pentagon [tex]= x + 80[/tex]
We know that,
Perimeter = Sum of all the sides
Since the perimeter is 401 inches, the side can be determined through:
[tex]401 = x+x+20+x+40+x+60+x+80[/tex]
⇒ [tex]401 = 5x + 200[/tex]
⇒ [tex]401 - 200 = 5x[/tex]
⇒ [tex]201/5 = x[/tex]
∵ [tex]x = 40.2[/tex]
Thus, 40.2 is the correct answer.

The distance between Jerry's house and school is
2.5 miles. How many yards is this?
1 mile = 1,760 yards
A) 4,400 yards
B) 3,520
C) 1,763 yards
D) 704 yards
Answer:
A) 4,400 Yards
Step-by-step explanation:
First, I added 1,760 + 1,760 together to represent 2 miles, and you get 3,520. Then, because it is a half mile you cut 1,760 in half to get 880. Finally, just add 3,520 + 880, which equals 4,400. I hope this helps :)

Which is the sum of 8 3/4 +2 1/2?
O A. 11 1/6
B. 11 1/4
O C. 10 1/2
O D. 10 1/4
please help fast
Answer:
B. 11 1/4
Step-by-step explanation:
8 3/4 + 2 2/4 = 11 1/4
We want to sum two mixed numbers.
The correct option is D: 11 1/4
A mixed number is a number that is separated into a whole part and a rational part.
Here we want to sum:
(8 3/4) + (2 1/2)
This can be written as:
8 + 3/4 + 2 + 1/2
Now we group the whole numbers and we group the rational numbers:
8 + 3/4 + 2 + 1/2 = (8 + 2) + (3/4 + 1/2) = 10 + (3/4 + 1/2).
To perform the sum of the rational numbers, we can write:
1/2 = 2/4
Then we have:
10 + (3/4 + 1/2) = 10 + (3/4 + 2/4) = 10 + 5/4 = 10 + 4/4 + 1/4 = 11 + 1/4
Then we can see that the correct option is D.

Answer:
no habla espanol, sorry
Answer:
Utilizando la fórmula 2 y sustituyendo los valores indicados:
Precio de venta = Precio original - Valor del descuento. Así,
Precio de venta = 45 - 31.5
Precio de venta = $13.5 (respuesta)
Esto significa que el costo del artículo para usted es $13.5.
Usted pagará $13.5 por un artículo cuyo precio original fue $45 con un descuento de 70%.
