Answer:

17.76

Step-by-step explanation:

0.44 x 4 = 1.76

4 x 4 = 16

16+1.76=17.76

Answer:

x = 26

Step-by-step explanation:

Start with - 9 + x = 17,   or   -9 + x = 17

Solve for x by isolating x on the left side.  To do this, add 9 to both sides, obtaining x = 26

Answer:

B

Step-by-step explanation:

Since T is at the midpoint of SU, then

ST = TU , substitute values

8x = 3x + 20 ( subtract 3x from both sides )

5x = 20 ( divide both sides by 5 )

x = 4

Thus

ST = 8x = 8(4) = 32

Answer:

-3p - p²

Last option

Step-by-step explanation:

Step 1: Write out expression

2p - 7p² - 5p + 6p²

Step 2: Combine like terms (p²)

-p² + 2p - 5p

Step 3: Combine like terms (p)

-p² - 3p

Step 4: Rewrite

-3p - p²

Answer:

x ≤ 4/7

Step-by-step explanation:

Simplify the given 2x ≤ -2/3 (4x + 4) by multiplying both sides by (3/2):

(3/2)(2x) ≤ (3/2)(-2/3)(4x + 4)

We get 3x ≤ -4x - 4

Solve for x by combining like terms.  Add 4x to both sides, obtaining

7x ≤ 4

and so the solution is the set

x ≤ 4/7

1. You are going to 6 cups to fl oz.

2. 6 cups is equal to 48 fluid ounces.

3. Then i did a guessing game from there. .20 was to much per fl oz. .10 was too much. .05 was just right

Answer:

Step-by-step explanation:

Given the function C(x) = x 2 + 78 x + 29 models the cost, in hundreds of dollars, to produce x thousand pens, we are to interpret C(0), C(2) and C(4).

For C(0), we are to substitute x = 0 into the given function;

C(0) = 0²+78(0)+29

C(0) = 0+0+29

C(0) = 29

Since the cost C(x) is in hundreds of dollars, C(0) = 2900

C(0) means that the cost of producing 0 thousand pen is $2,900

For C(2), we are to substitute x = 2 into the given function;

C(2) = 2²+78(2)+29

C(2) = 4+156+29

C(2) = 189

Since the cost C(x) is in hundreds of dollars, C(2) = 189*100 = $18900

C(2) means that the cost of producing 2 thousand pens is $18,900

For C(4), we are to substitute x = 4 into the given function;

C(4) = 4²+78(4)+29

C(4) = 16+312+29

C(4) = 357

Since the cost C(4) is in hundreds of dollars, C(4) = 357

C(4) means that the cost of producing 4 thousand pens is $35,700

Answer:

5.101 x 10^14 m^2

Step-by-step explanation:

First you have to convert km to metres (the final answer must in metres).

So that would be 12742000m. Remember this is the diameter. The radius is half the diameter. So the radius would be 6371000m.

You then put it into the formula: 4 x π x 6371000².

And then you would get the answer: 5.101 x 10^14 m^2

Answer:

The similarities are

1) The length of E and F can be described by two parallel lines spaced 3 blocks apart where the parallel line on the left of both E and F is 2 blocks long, while the parallel line on the right is one block long

2) Both height of E and F can be described by two parallel lines spaced 2 blocks apart  where the parallel line on the top of both E and F is 3 blocks long, while the parallel line at the bottom is one block long

3) The interior of E an F can be described by parallel lines 2 blocks long in the horizontal portion and one block long in the vertical portion

The differences are

1) The difference between E and F is that the parallel lines used for the construction of E are all one block higher than that of F

2) The other difference is that all the lines used for the construction of the figure E are 3 blocks to the left of those used for the construction of F

Figure F is essentially the translation of figure E three blocks to right and one block down

Answer:

-Step-by-step explanation:

Answer:

Step-by-step explanation:

[tex]d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}\\\\d=\sqrt{(6+8)^2+(-1+2)^2}=\sqrt{14^2+1^2}=\sqrt{197}=14.035668...\approx14.04[/tex]

The distance is 14.03.

The distance formula which is used to find the distance between two points in a two-dimensional plane is also known as the Euclidean distance formula. To derive the formula, let us consider two points in 2D plane A(x1,y1), and B(x2,y2).

Assume that 'd' is the distance between A and B.

d= √(x2 - x1)² + ( y2 - y1)²

Given coordinates:

(-8,-2)  and (6,-1)

Using distance formula,

=√(6+8)² + ( -1 +2)²

=√14²+1²

=√196+1

=√197

= 14.0356

≈14.03

Answer:

Well, Two integers are relatively prime (or coprime) if there is no integer greater than one that divides them both (that is, their greatest common divisor is one). For example, 12 and 13 are relatively prime, but 12 and 14 are not.

Answer:

372

There are already 3 terms. So, now you have to find the 30th term.

The difference of 30 - 3 is 27. Now, since you add 9 for every term, multiply it by 27.

27 x 9 = 243.

The third term is 29. So you add 29.

Your answer will be 372. Hope it helps.

It's the second one.

Step-by-step explanation:

It's the second one because the volume of the radius is v and 4/3 gives the radius and after that if you look at the second three then use a calculator to multiple the numbers up it tells you what the numbers are and the number give you r for the volume so it makes it the second one.

1. y=3  

2.x=4

3. k= -2

4.n= -45

5. c = -3

6. p = 4

Step-by-step explanation:

Answer:

Yes

Step-by-step explanation:

Yes it is possible to get the same output by providing two different inputs in a solution.

For example :

Let a function, [tex]$y = x^2 $[/tex]  ......(1)

Case 1

let x = -2, putting the value of x in equation (1), we get

[tex]$y = x^2 $[/tex]

[tex]$y = (-2)^2 $[/tex]

   = 4

Case 2

let x = 2, putting the value of x in equation (1), we get

[tex]$y = x^2 $[/tex]

[tex]$y = 2^2 $[/tex]

  = 4

Therefore, for both the different input (x), we get the same output (y).
