Answer:

-8.5 but i am not sure

The rational number between -8 and -9 can be -8.1, -8.2, -8.3, -8.4, -8.5, -8.6, -8.7, -8.8, -8.9,

Given,

-8 and -9

We need to find a rational value between -8 and -9.

A number that can be written in the form p/q and is terminating and recurring.

Example:

2, 1/3, 5/2

Find the rational number between -8 and -9.

In between -8 and -9 we can have the following number:

-8.1, -8.2, -8.3, -8.4, -8.5, -8.6, -8.7, -8.8, -8.9

We see that all these values are rational numbers.

Thus -8.1, -8.2, -8.3, -8.4, -8.5, -8.6, -8.7, -8.8, -8.9 can be an example of rational number between -8 and -9.

Answer:

x = -12  or  x = 16

Step-by-step explanation:

| x - 2 | - 6 =8  

           +6    +6

------------------------

| x - 2 | = 14

---> we get x = -14

---> we get  x = 14

so, x = -12, or, x = 16

Answer: I believe its the one that says "each dog is fed between 1 and 3 pounds of dog food each week"

Step-by-step explanation:

To give each dog an equal amount you'd have to divide 20 by 7.

20 / 7

when you do that is doesn't come out to a whole number

20 / 7 = 2.8571428571

anything higher than 2.8 pounds would go over his limit of 20 pounds

so true statement I think would be the one that says between 1 and 3.

Answer:

[tex]12w+24[/tex]

Step-by-step explanation:

[tex]9w−3(−w−8)[/tex]

[tex]9w+(−3)(−w)+(−3)(−8)[/tex]

[tex]9w+3w+24[/tex]

[tex](9w+3w)+(24)[/tex]

[tex]12w+24[/tex]

In the simplest form we can write the expression as - 12(w + 2).

We have the following expression -

9w - 3(- w - 8)

We have to write it in simplest form.

Expanding we get -

Δ = x(x - β) - α(x - β)

Δ = [tex]x^{2}[/tex] - βx - αx + αβ

According to the question, we have -

9w - 3(- w - 8)

Simplifying it, we get -

9w + 3(w + 8)

9w + 3w + 24

12w + 24

12(w + 2)

Hence, in the simplest form we can write the expression as - 12(w + 2).

[tex]( x + 4 )^2 + ( y - 7 )^2 = 36[/tex]

Step-by-step explanation:

Use the circle equation, [tex]( x - h )^2 + ( y - k )^2 = r^2[/tex]

Plug in the center and radius:

[tex]( x + 4 )^2 + ( y - 7 )^2 = 6^2[/tex]

Simplify:

[tex]( x + 4 )^2 + ( y - 7 )^2 = 36[/tex]

So, the equation is [tex]( x + 4 )^2 + ( y - 7 )^2 = 36[/tex]

Angle ABC = 57°

Step-by-step explanation:

Hi there!

We're given:

⇒ ABD is a straight line

⇒ Angle ABC = 5x-18 degrees

⇒ Angle DBC = 8x+3 degrees

ABD is a straight line, meaning it measures an angle of 180 degrees.

Angles ABC and DBC create line ABD, so therefore, their sum is equal to 180 degrees:

[tex](5x-18)+(8x+3)=180[/tex]

Open the parentheses:

[tex]5x-18+8x+3=180[/tex]

Combine like terms:

[tex]13x-15=180\\13x=195[/tex]

Divide both sides by 13 to isolate x:

[tex]x=15[/tex]

Therefore, x = 15.

To find angle ABC, replace x with 15 in 5x-18:

[tex]5x-18\\=5(15)-18\\=75-18\\=57[/tex]

Therefore, the measure of angle ABC is 57 degrees.

Answer: Circumference = 7.85 inches

Concept:

Here, we need to know the idea of circumference.

The circumference is the perimeter of a circle. The perimeter is the curve length around any closed figure.

Circumference = 2πr

r = radius

π = constant

Solve:

Given information

r = (1/2) d = (1/2) (2.5) = 1.25 inches

π = 3.14

Given formula

Circumference = 2πr

Substitute values into the formula

Circumference = 2 · (3.14) · (1.25)

Simplify by multiplication

Circumference = (2.5) · (2.14)

Circumference = [tex]\boxed {7.85 inches}[/tex]

Answer:

Step-by-step explanation:

First of all, your formula isn't right. In general, the KE = 1/2 m * v^2

KE = 1/2 m * v^2                         Multiply both sides by 2

2*Ke = m * v^2                           Now divide by v^2

2*Ke/v^2 = m
