how is -27 a rational number

Answer:

Inches is the best answer

Step-by-step explanation: This is because it is the only one that actually makes sense in the context of the question. Pint is for liquids, degrees is for angles, and moles is for molecules.

Saving after w weeks:7w+75

Answer:

| - 19 - (- 8) |

Step-by-step explanation:

Given that the 2 points have the same x- coordinate, then the distance between the 2 points is the difference in the y- coordinates, that is

distance = | - 19 - (- 8) | = | - 19 + 8 | = | - 11 | = 11

Or

distance = | - 8 - (- 19) | = | - 8 + 19 | = | 11 | = 11

Answer:

Step-by-step explanation:

f(x) = - 4x - 6

g(x)=3x+5

To find (f o g)(-3) we must first find

(f o g)(x)

To find (f o g)(x) substitute g(x) into f(x) that's for every x in f (x) replace it with g (x)

That's

(f o g)(x) = - 4( 3x + 5) - 6

= - 12x - 20 - 6

(f o g)(x)= - 12x - 26

Now to find (f o g)(-3) substitute the value of x that's - 3 into (f o g)(x) and solve

We have

(f o g)(-3) = - 12(-3) - 26

= 36 - 26

We have the final answer as

(f o g)(-3) = 10

Hope this helps you

Step-by-step explanation:

Collinear points: Three points A, B and C are said to be collinear if they lie on the same straight line. There points A, B and C will be collinear if AB + BC = AC as is clear from the adjoining figure.

Answer:

The lengths of the sides are 30 ft, 60 ft, 15 ft, 45 ft

Step-by-step explanation:

The perimeter is 150 ft, the length of the fence.

We add the lengths of the sides and set equal to the perimeter. Then we solve for x. Once we know x, we find the length of each side.

x + 2x + 0.5x + 45 = 150

3.5x = 105

x = 105/3.5

x = 30

Lengths of sides:

x = 30

2x = 2(30) = 60

0.5x = 0.5(30) = 15

45

Answer: The lengths of the sides are 30 ft, 60 ft, 15 ft, 45 ft

Answer:

Step-by-step explanation:

Acid present in the solution = 10 L

Required volume concentration of acid = 8/100

Let x amount of water be added to achieve the required %.

In the new solution, proportion of acid= 10/(50+x)

Therefore,

10/(50+x) = 8/100

x=75

Ans: 75 L of water must be added to the solution

Answer: the numbers can be 16 and 9, 6 and 24 or other factors of 144

Answer:

This question seems to be incomplete, so i will answer it in a general way.

If we have a vector;

b = (b1, b2)

where b1 and b2 are the x-component and the y-component (respectively) of the vector b, then we can write the vector as:

b = (b1, b2) = b1*x^ + b2*y^

Where x^ = (1, 0) and y^ = (0, 1)

Are the unit vectors.

Answer:

2/3

Step-by-step explanation:

Let n = the repeating, non-terminating number 0.666...

We now have n = 0.666666...

We want the number n in the form of a fraction.

Since only 1 digit repeats, the 6, use a 1 followed by 1 zero, which means the number 10. Now multiply both sides by 10 and write the original equation below it.

10n = 6.666666...

   n = 0.666666...

Subtract the bottom equation from the top equation.

9n = 6

n = 6/9

n = 2/3

Answer: C   -3< y ≤ 3

Step-by-step explanation:

Starting from the lowest point of the  y coordinate to the highest point of the y coordinate. The lowest point is -3 and highest point is 3.At the y coordinate -3 there is an open circle which means we are excluding it and at the highest point 3 there is a closed circle so we will have to include that.

Here you go. This is the graph of the function:

Answer:

plane intersects a 3D shape

I'm assuming you want to solve for  z  :)

By simplifying both sides of the equation, then isolating the variable.

Exact form:

z= -5/3 , - 11/3

Mixed number form:

z=  −1  2/3  ,  −3  2/3

Answer:

There are two solutions, -5/3 and -11/3

Step-by-step explanation:

Move -5 to the right side and add:

-5 | 3x + 8 | = -15

Get rid of the absolute-value bars by splitting them into negative and positive cases.

Solve negative case

-5 ( 3z + 8 ) = -15

Distribute or Multiply:

-15z - 40 = -15

Rearrange and Add:

-15z = 55

Divide both sides by 15:

-z= 11/3

Multiply both sides by -1:

z= -11/3

Solve negative case

5 ( 3z + 8 ) = -15

Distribute or Multiply:

15z + 40 = 15

Rearrange and Add:

15z = -25

Divide both sides by 15:

z = -(5/3)

Answer

z=-11/3

z=-5/3

By Looking at the shapes and sizes

Step-by-step explanation:

If you can try and look at the shape and size of it, if you can draw it, draw it on a piece of paper, trace them both, but in the same spot, you didn't specificize, if it was a sphere or just a regular circle or not, so thats all i can tell you.
