Step-by-step explanation:

The total cost of materials can be found from a list of materials based on the market unit rate.

The correct responses are;

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

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%.

En otras palabras, si usted compra una mercancía por $45 con 70% de descuento, Usted pagará $(45 - 31.5) = $13.5

14 squared + 10 squared not-equals 20 squared. Therefore, option A is the correct answer.

The Pythagoras theorem which is also referred to as the Pythagorean theorem explains the relationship between the three sides of a right-angled triangle. According to the Pythagoras theorem, the square of the hypotenuse is equal to the sum of the squares of the other two sides of a triangle.

Given that, the completed frame is 14 inches long and 10 inches wide.

Tasha measured the diagonal length across the frame as 20 inches.

By using Pythagoras theorem, we have

20²=10²+14²

400=100+196

400≠296

Therefore, option A is the correct 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

The length of the shortest side of the pentagon would be:

40.2

Given 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.

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.
