Answer:

A piece of duct measures 48 inches.

In each connection, we lost 1.72 inches (it also could be 1/2 inches, but i will go with the other option)

Then:

If we have 7 pieces of duct connected we have 5 connections (the ones in the extremes are not connected between them)

So here we have 7 times 48 inches for the pieces, minus 5 times 1.72 inches for the connections, the length is:

L = 7*48in - 5*1.72in = 327.4 inches.

for the 12 pieces duct, we have 12 pieces and 10 connections, so the length is:

L = 12*48in - 10*1.72in = 558.8 in

Now, if we want to make only one duct with those two, then we must add their lengths, but if we connect them, we also need to subtract the 1.72in of the new connection:

L =  558.8 in +  327.4 in - 1.72in = 884.48 in

Answer:3

Step-by-step explanation: 3(3)-4 =5

Area now is 5•5 equivalent to 25 :)

The value of x is 8.

Given that, the perimeter of a square is 3x-4 units, and the area of the square is 25 sq units, we need to find the value of x,

We know that the perimeter of the square = 4(sides)

Therefore,

4(sides) = 3x-4

sides = 3x-4 / 4

Now, the area = side²

= (3x-4 / 4)²

therefore,

(3x-4 / 4)² = 25

Taking the roots,

3x-4 / 4 = 5

3x-4 = 20

3x = 24

x = 8

Answer:

Answer is C.

Step-by-step explanation:

When radius is 1, the volume is 4. When radius is 2, it's 32. Which means It becomes 8 times bigger because 32 divided by 4 (32/4) is 8.

Step-by-step explanation:

4x-5y=0

5y=4x

y=4x/5, or rather y = (4/5)*x

k thus equals 4/5, and that is your constant of variation.

Answer:

2x(3x + 2)

Step-by-step explanation:

Answer

102

Step-by-step explanation:

X means 3 not times, lots of people mess that up sometimes. Anyways, do 8+3 which equals 11. 8+3=11. So next what you do is you do 11 + 16 which is 27,

equations:

8+3=11

11+16=27

21/1=27

27/4= 6.75

6 x 3= 27

27 + 72 + 3= 102

Then go back to the beginning and do 1/4. If this confuses let me fix it.

now divide it with 4. Look at the equations list. Okay now do 6.72/4x. MAKE SURE TO MULTIPLY DON'T DIVIDE! You multiply 6 and 4 then you add 72 and three! Then you should end up with 102! I hope this worked message me back if it did :)

Answer: 3: 42.49

Step-by-step explanation:

_________________________________

Hey!!

Solution,

Marked price (MP)=$ 49.99

Discount percent=15%

Sale price (SP)=?

Now,

Discount amount=discount% of MP

=15% of 49.99

=$7.4985

Again,

Sale price=MP- Discount

=49.99-7.4985

=$ 42.49

So the sale price is $42.49

Hope it helps..

Answer:

There are 50 dimes and 110-50 = 60 quarters in the collection.

Step-by-step explanation:

Let D be the number of dimes.

Then the number of quarters is (110-D).

The "value equation" is

10D + 25*(110-D) = 2000.

Simplify and solve for D:

10D + 2750 - 25D = 2000,

-15D = 2000 - 2750,

-15D = -750,

D = %28-750%29%2F%28-15%29 = 50.

Answer:

$43,200

Step-by-step explanation:

25% is 1/4 of the total dollar value, to find the answer we need to multiply 10,800 by 4 (it is 1/4, and the answer will be equivalent to the 4/4)

10,800 * 4 = 43,200

The total dollar value of the art that he sells is 43200 dollars.

Percentage is the value per hundredth.We can also convert percentages into decimals by dividing he percentage value by 100.

According to the given question Pierre, an art dealer, earns 25% commission of the dollar value of the art pieces that he sells at the Bizzell Gallery. Pierre earns $10,800.

∴ 25% of the total value is 10800 dollars.

Assuming total value to be x dollars.

So, (25/100)x = 10800

(1/4)x = 10800

x = 10800 × 4

x = 43200 dollars.

Answer:

1) {(0,5), (4,2), (6,9), (9,10)}

Step-by-step explanation:

Lets right the table in more clearer view.

x         f(x)

0           5

4           2

6           9

9          10

The relation in coordinates form is written as (x, y) , x being the first term and y being the second term.

For x = 0, y = 5, so it can be written as (0,5)

Similarly, we can write the next values as:

(4,2)

(6,9)

(9,10)

So the data in the table is:

(0,5), (4,2), (6,9), (9,10)

It can be written is a set form

{(0,5), (4,2), (6,9), (9,10)}

Which is the same as option 1.

Hence, Option 1 is correct.
