Sum of the interior angle measures of the polygon with 9 sides

1 answer:

5 0

Hello There!

The sum of interior angles for any polygon is:
(n - 2) x 180
Where 'n' is the number of sides.
In this case, the polygon is a nonagon, which has 9 sides.
Substitute the value in:
(9 - 2) x 180 = ?
Solve:
Sum of interior angles = 1260°.

Hope This Helps You!
Good Luck :)

asambeis [7]

Answer:

Step-by-step explanation:

If two variables are proportional then

$y\propto x$

$y=kx$ ...(i)

where, k is constant of proportionality.

The given equation is

$s=4c$ ...(ii)

where,

s = number of cups of seltzer.

c = cups of cranberry juice.

On comparing (i) and (ii), we get

Independent variable: $x=c$

Dependent variable: $y=s$

Constant of proportionality: $k=4$

Therefore, the constant of proportionality is 4.

galina1969 [7]

Answer:

2-2/3 hours

Step-by-step explanation:

1/4 + 2/3 + 1-3/4 = 1/4 + 2/3 + 7/4. Use common is 12, so we get 3+8+21/12 = 32/12. Simplify equal 8/3 or 2-2/3 hours!

If gasoline costs 2.14 per gallon and you drive 500 miles in a car that gets 30 mpg, what is the cost of gasoline

Vlad [161]

Answer:

35.7

Step-by-step explanation:

First, you would calculate how many gallons of gasoline the car gets. To do this, divide your total mileage of 500 miles by the mpg (30). Now you know how many gallons of gasoline will be used by the car. After calculating, you get 16.67. Multiply this by how much it costs per gallon of gasoline, and you get an answer of $35.7.

The graph shows the exponential regression model for data representing a rabbit population after x years. Which is true of the r

tamaranim1 [39]

Answer: The graph of the regression model can be used to predict the population size for any number of years in the future.

Step-by-step explanation:

Since with help of the given graph, we can say that

The graph of the regression model is applied for the every real value of x.

Thus the statement The graph of the regression model is limited to whole-number values for x is false.

Also, the range of an exponential function is always a set of real number.

Therefore, The graph of the regression model is limited to whole-number values for y is false.

Since, for 1 year, the approximate population is given,

Therefore, The graph of the regression model cannot be used to approximate the population size for year 1 is false.

Again according to the given graph we can say that we can get the population for any number of year.

Thus, The graph of the regression model can be used to predict the population size for any number of years in the future is true.
