Need help with a problem. For some reason I can not seem to get it correct. Thinking my formula is wrong. Here's the problem:Assume that there are approximately 140x10^9 stars in our galaxy.Our galaxy is 50,000 light years from the center to the edge, but just 1,000 light years thick. It's shaped like a thin disk or cylinder. If the stars were distributed equally throughout the galaxy, how many stars would you expect to find in one cubic light year?I thought it would be Pi*r^2*l. Then divide that by the number of stars. What am I doing wrong? Thanks, been 20 years since I had to do math like this!

As the given image is of a triangle and MN is one of the sides of the triangle. After solving the given equation, the value is 71.

What are the sides of triangle?

There are three sides and three angles in every triangle, some of which may be the same. In the case of a right triangle, the three sides are given unique names: the hypotenuse, which is the side that faces the right angle, and the legs, which are the other two sides.

Every triangle is bicentric and convex. A triangle with angles requires at least one side in order to determine the length of the side. The length of the triangle's sides can then be determined using the law of sines.

4x + 19 = 6x - 7

19 + 7 = 6x - 4x

26 = 2x

26 / 2 = x

13 = x

When the derived value of x is putted in the given equation, the value will be,

4x + 19 = 4 × 13 + 19 = 52 + 19 = 71

Therefore, after solving the given equation, the value is 71.

Answer:

MN = 71

Step-by-step explanation:

You first gotta know the value of x by putting both equations in line!

4x + 19 = 6x - 7

4(13) + 19 = 6(13) - 7

52 + 19 = 78 - 7

71 = 71

Answer:x = 13

Then we already have the length of MN!

Answer:MN = 71

Does the following equation have an answer?2n²=m √m=o {n ∈ N*} {o ∈ N*} {m ∈ N*}
It had wondering for days...

Answers

We see that n is in the set of natural numbers (1,2,3,4,5,...), so of course m should be in the natural numbers. However, we see that 2n^2, when square rooted, is $n√(2)$ . With n in the natural numbers, the square root of m, or o, can never be a natural number but is always an irrational number. Therefore, this equation has no solutions.

Part B: The area of a rectangle is (81x2 − 4y2) square units. Determine the dimensions of the rectangle by factoring the area expression completely. Show your work. (5 points)

Answers

The dimensions of the rectangle are 9x + 2y units and 9x - 2y units.

What is the area of the rectangle?

The area of the rectangle is the product of the length and width of a given rectangle.

The area of the rectangle = length × Width

To determine the dimensions of the rectangle, we need to factor the area expression completely. We can use the difference of squares formula to do this. The formula is:

a2 - b2 = (a + b)(a - b)

We are given that;

Area of rectangle= (81x2 − 4y2) square units.

Now,

We can identify that 81x2 and 4y2 are both perfect squares. The square roots of them are 9x and 2y respectively. So we can rewrite the area expression as:

81x2 - 4y2 = (9x)2 - (2y)2

Using the difference of squares formula, we can factor this expression as:

(9x)2 - (2y)2 = (9x + 2y)(9x - 2y)

We can check this by multiplying them and getting back the original area expression.

(9x + 2y)(9x - 2y) = 81x2 - 18xy + 18xy - 4y2 (9x + 2y)(9x - 2y) = 81x2 - 4y2

Therefore, by the given area the answer will be 9x + 2y units and 9x - 2y units.

Kent worked in the housewares section of a department store this year he set a record high for vacuum sales with 567 vacuum sold the previous high was last year when 540 vacuums were sold what is the percent of increased in sales from last year to this year?

Answers

The percent increase in vacuum sales from last year to this year is 5%. This means that there was a 5% increase in the number of vacuums sold this year compared to last year's sales.

To calculate the percent increase in vacuum sales from last year to this year, we can use the following formula:

Percent Increase = [(New Value - Old Value) / Old Value] * 100

Where:

New Value = 567 (vacuums sold this year)

Old Value = 540 (vacuums sold last year)

Now, let's plug in the values and calculate:

Percent Increase = [(567 - 540) / 540] * 100

Percent Increase = (27 / 540) * 100

Percent Increase = 0.05 * 100

Percent Increase = 5%

The percent increase in vacuum sales from last year to this year is 5%. This means that there was a 5% increase in the number of vacuums sold this year compared to last year's sales.

One percent of 540 is 5.4 (540\100) now divide 567 by that number which gives you 105% take the original 100% away, it's an increase of 5%
