how do you factor 30n^2b-87nb+30b?

Answers

Answer 1

It's not clear whether you meant 30n^(2b) or [30n^2] b.

I will assume the latter.

b can then be factored out of all three terms, resulting in

b [30n^2 - 87n + 30] = b [ 3 ] [10n^2 - 29n + 10 ]

Can you factor this further?

45+5/6x=50
need to find x and math for x

Answers

45 + 5/6x = 50

5/6x = 50 - 45

5/6x = 5

5x = 5 * 6

5x = 30

x = 6

hope that helps, God bless!

The solution of expression is, x = 6

We have to give that,

An expression to simplify as,

⇒ 45 + 5/6x = 50

Now, Simplify the expression by combining like terms,

⇒ 45 + 5/6x = 50

Subtract 45 on both sides,

⇒ 45 + 5/6x - 45 = 50 - 45

⇒ 5/6x = 5

Multiply by 6 on both sides,

⇒ 5x = 5 × 6

⇒ 5x = 30

Divide by 5 on both sides,

⇒ x = 30/5

⇒ x = 6

So, The solution is, x = 6

How much greater is the area of a square with a side length of 9 inches than the area of a circle with a radius of 3 inches?

Answers

The area of the square is 81 sq in, and the area of the circule is (3.14)(3 in)^2, or approx 3.14(9) sq in, or approx 28.27 sq in.

Subtract: 81 sq in - 28.27 sq in = approx. 52.73 sq in.

The difference is 52.73 sq in; the square is larger, the circle smaller.

Answers

The reference angle is simply the acute angle between the terminal side and the x-axis

The terminal angles in the four quadrants are

[tex]\bar \theta = \theta[/tex].[tex]\bar \theta = \pi - \theta[/tex].[tex]\bar \theta = \theta - \pi[/tex].[tex]\bar \theta = 2\pi - \theta[/tex]

The given parameters are:

[tex]\theta \to[/tex] reference angle

[tex]\bar \theta \to[/tex] terminal angle

(a) If the reference angle is in the first quadrant

In the first quadrant, the x-axis is at [tex]0\ rad[/tex]

So, the terminal angle is:

[tex]\bar \theta = \theta - 0[/tex]

[tex]\bar \theta = \theta[/tex]

(b) If the reference angle is in the second quadrant

In the second quadrant, the x-axis is at [tex]\pi \ rad[/tex],

While the reference angle is between [tex]\frac{\pi}{2}[/tex] and [tex]\pi \ rad[/tex]

It means that, we have to subtract the reference angle from the x-axis

So, the terminal angle is:

[tex]\bar \theta = \pi - \theta[/tex]

Here, the x-axis is still at [tex]\pi \ rad[/tex],

But the reference angle is between [tex]\pi \ rad[/tex] and [tex]\frac{3}{2}\pi[/tex]

It means that, we have to subtract the x-axis from the reference angle.

So, the terminal angle is:

[tex]\bar \theta = \theta - \pi[/tex]

(d) If the reference angle is in the fourth quadrant

Here, the x-axis is at [tex]2\pi \ rad[/tex]

And the reference angle is between [tex]\frac{3}{2}\pi[/tex] and [tex]2\pi \ rad[/tex]

It means that, we have to subtract the reference angle from the x-axis.

So, the terminal angle is:

[tex]\bar \theta = 2\pi - \theta[/tex]

A section of a roller coaster track forms a parallelogram ABCD.

If m∠ABC = 72°

Since ABCD is a parallelogram .

So, "Sum of interior angles on the same side is supplementary":

[tex]m\angle ABC+m\angle DAB=180\textdegree\\\\72\textdegree+m\angle DAB=180\textdegree\\\\m\angle DAB=180\textdegree-72\textdegree\\\\m\angle DAB=108\textdegree[/tex]

Two right triangles are congruent. Find the value of x.
right triangle with angle of 33 degrees, right triangle with angle of 9 x minus 15 degrees
Select one:
a. 5
b. 6
c. 8
d. 12

Answers

Given that the two right triangles are congruent, there are two possibilities.

9x - 15 is equal to the angle 33° or 9x - 15 is equal to the other angle of the first triangle.

Let's probe with the first option:

9x - 15 = 33 => 9x = 33 + 15 = 48

=> x = 48 / 9 = 5,33, which is no in the list of options.

Now, let's probe the second option.

The other angle of the first right triangle is 90° - 33° = 57°

Then, 9x - 15 = 57

=> 9x = 57 + 15 = 72

=> x = 72 / 9 = 8

Which is the option c. 8.

So, I am sure that if you have a figure it will be compatible with that answer, else yet the procedure to find the answer is what I have used here.

Answer: option c. 8

F=J+Jrt solve following formula for t

Answers

F=j+jrt
F-j=jrt
t=(F-j)/jr

Final answer:

To solve the formula F=J+Jrt for 't', first, subtract 'J' from both sides to get F-J=Jrt. Then, divide both sides by 'Jr', for the final equation for 't' = (F-J)/Jr.

Explanation:

This physics-related mathematics question is asking you to solve the given formula F=J+Jrt for 't'. To isolate 't', we first want to eliminate 'J' from the right side. We do this by subtracting 'J' from both sides of the equation. This gives us F-J=Jrt.

Then, we divide both sides by 'Jr'. When we do this, we are left with t=(F-J)/Jr as the rearranged formula with 't' as the subject. This results in 't' being isolated in the equation, which answers the student's question.
