Answer:

2.174 hours

Step-by-step explanation:

Let the number of hours be represented as:

x

The price of Stock A at 9 A.M. was ​$12.79 Since​ then, the price has been increasing at the rate of ​$0.11 each hour.

$12.79 + $0.11 × x

12.79 + 0.11x

At noon the price of Stock B was ​$13.29 It begins to decrease at the rate of ​$0.12 each hour.

$13.29 - $0.12× x

13.29 - 0.12x

Equating both equations together

Stock A = Stock B

12.79 + 0.11x = 13.29 - 0.12x

Collecting like terms

0.11x + 0.12x = 13.29 - 12.79

0.23x = 0.5

x = 0.5/0.23

x = 2.1739130435 hours

x = Approximately = 2.174 hours

If the two rates​ continue, the number of hours that the prices of the two stocks will be the​ same is 2.174 hours

(5s-6)(3s+2) please just give me the answer I have to turn it in today
alexandr1967 [171]

Answer:

The answer is -2

Step-by-step explanation:

you subtract common numbers, so:

5s - 3s = 2s

Then,

-6 + 2 = -4

You would then get

2s - 4

divide -4 by 2 which is -2

and your answer is s = -2

3g2+4g+1=0 solve for g
gulaghasi [49]
- - Lets solve for G.

Keep in mind: G is acting as a unknown variable, commonly used as "x"
So we need to find the variable, and then we solve for g until we get "0" for our problem.
Okay so lets start off by factoring our equation, in this case you do left first.

3g+1*g+1=0
Alright, now we can set out "o" as the equal to all of our factors.
g+1=0
And now you need to solve for that,
And you get -1 for our answer.

Final answer: g=-1

The ages of the members of a gym have a mean of 4747 years and a standard deviation of 1111 years. what can you conclude from​ c
Bond [772]

Chebyshev came up with the limits on how much or how many of the data must lie close to the mean. In specific for any positive k, the proportion of the data that lies within k standard deviations of the mean is at least: <span>

1 - 1/k² 

<span>In this problem  the mean is 47 yrs therefore:

(47 – 17.3) = 29.7 = (76.7 - 47) </span></span>

The value of k is calculated using the formula:<span>

29.7 / 11 = 2.7 = k</span>

So the % of gym members aged between 19.4 and 76.6 is: <span>

1 - 1 / (2.6)² = 0.863 = 86.3 %</span>

 

<span>Therefore 86.3% of the gym members are aged between 19.4 and 76.6</span>

How to find the area of a polygon
Lelechka [254]

Answer:

Calculating the area of a polygon can be as simple as finding the area of a regular triangle or as complicated as finding the area of an irregular eleven-sided shape. If you want to know how to find the area of a variety of polygons, just follow these steps.

Step-by-step explanation:

1.) Write down the formula for finding the area of a regular polygon. To find the area of a regular polygon, all you have to do is follow this simple formula: area = 1/2 x perimeter x apothem.[1] Here is what it means:

Perimeter = the sum of the lengths of all the sides

Apothem = a segment that joins the polygon's center to the midpoint of any side that is perpendicular to that side

2.)  Find the apothem of the polygon. If you're using the apothem method, then the apothem will be provided for you. Let's say you're working with a hexagon that has an apothem with a length of 10√3.

3.)  Find the perimeter of the polygon. If the perimeter is provided for you, then you're nearly done, but it's likely that you have a bit more work to do. If the apothem is provided for you and you know that you're working with a regular polygon, then you can use it to find the perimeter. Here's how you do it:

Think of the apothem as being the "x√3" side of a 30-60-90 triangle. You can think of it this way because the hexagon is made up of six equilateral triangles. The apothem cuts one of them in half, creating a triangle with 30-60-90 degree angles.

You know that the side across from the 60 degree angle has length = x√3, the side across from the 30 degree angle has length = x, and the side across from the 90 degree angle has length = 2x. If 10√3 represents "x√3," then you can see that x = 10.

You know that x = half the length of the bottom side of the triangle. Double it to get the full length. The bottom side of the triangle is 20 units long. There are six of these sides to the hexagon, so multiply 20 x 6 to get 120, the perimeter of the hexagon.

4.) Plug the apothem and the perimeter into the formula. If you're using the formula area = 1/2 x perimeter x apothem, then you can plug in 120 for the perimeter and 10√3 for the apothem. Here is what it will look like:

area = 1/2 x 120 x 10√3

area = 60 x 10√3

area = 600√3

5.)  Simplify your answer. You may need to state your answer in decimal instead of square root form. Just use your calculator to find the closest value for √3 and multiply it by 600. √3 x 600 = 1,039.2. This is your final answer.
