a regular assignment has 15 sides.Calculate the size of each interior angle
Answer:
The measure of an interior angle of a regular 15-gon is 120°.
Step-by-step explanation:
We need to determine the measure of the size of an interior angle of a regular 15-gon having 15 sides.
Thus,
The number of sides n = 15
Hence,
Using the formula to determine the measure of an interior angle of a regular 15-gon is given by
(n - 2) × 180° = n × interior angle
substitute n = 15
(15 - 2) × 180 = 15 × interior angle
13 × 180 = 15 × interior angle
Interior angle = (10 × 180) / 15
= 1800 / 15
= 120°
Therefore, the measure of an interior angle of a regular 15-gon is 120°.

Answer:
1,250 meters.
Step-by-step explanation:
If you convert the 2 km into meters, you get 2000 meters. So after that you subtract 2000-750 and you should get 1,250
Hope this helps
2 kilomters = 2000 meters
Thus, to find out how much closer Adrian lives next to his school than Kevin you subtract the distance from kevin's home to his school (2000 meters) by the distance of Adrian's home to his school (750 meters).
2000 - 750 = 1250 meters
Therefore, Adrian lives 1250 meters closer to his school than Kevin.
The profit of a football club after a takeover is modeled by p(t)=t^3-14t^2+20t+120,where t is the number of years after the take over, in which years was the club making a loss ?
When looking at the following expression, we can tell that it has no rational roots. However, it does have zeros at:
t = -0.45, 2.16, 12.29.
When thinking of the cubic curves you know that p(t) < 0 for 2.16 < t < 12.29. Meaning the team took a loss in years 3-12.

Answer:
None, there are no degrees/exponents
Step-by-step explanation:
Hope this is helpful :)
Answer:
has three terms. The first term has a degree of 5 (the sum of the powers 2 and 3), the second term has a degree of 1, and the last term has a degree of 0. Therefore, the polynomial has a degree of 5, which is the highest degree of any term

A right triangle has legs of 18 inches and 24 inches whose sides are
changing. The short leg is increasing by 4 in/sec and the long leg is
shrinking at 9 in/sec. What is the rate of change of the hypotenuse?
Given:
A right triangle has legs of 18 inches and 24 inches.
The short leg is increasing by 4 in/sec and the long leg is shrinking at 9 in/sec.
To find:
The rate of change of the hypotenuse.
Solution:
Let x be the shorter leg (Base), y be the larger leg (Perpendicular) and z be the hypotenuse.
We have,
[tex]\dfrac{dx}{dt}=4\text{ in/sec}[/tex]
[tex]\dfrac{dy}{dt}=-9\text{ in/sec}[/tex]
[tex]x=18[/tex]
[tex]y=24[/tex]
According to the Pythagoras theorem,
[tex]Hypotenuse^2=Base^2+Perpendicular^2[/tex]
[tex]z^2=x^2+y^2[/tex] ...(i)
[tex]z^2=(18)^2+(24)^2[/tex]
[tex]z^2=324+576[/tex]
[tex]z^2=900[/tex]
Taking square root on both sides.
[tex]z=\pm \sqrt{900}[/tex]
Side cannot be negative. So,
[tex]z=30[/tex]
Differentiating (i) with respect to time t, we get
[tex]\dfrac{d}{dt}z^2=\dfrac{d}{dt}(x^2+y^2)[/tex]
[tex]2z\dfrac{dz}{dt}=2x\dfrac{dx}{dt}+2y\dfrac{dy}{dt}[/tex]
[tex]2(30)\dfrac{dz}{dt}=2(18)(4)+2(24)(-9)[/tex]
[tex]60\dfrac{dz}{dt}=144-432[/tex]
[tex]60\dfrac{dz}{dt}=-288[/tex]
Divide both sides by 60.
[tex]\dfrac{dz}{dt}=\dfrac{-288}{60}[/tex]
[tex]\dfrac{dz}{dt}=-4.8[/tex]
Here, negative sign means hypotenuse is decreasing.
Therefore, the hypotenuse is shrinking at 4.8 in/sec.

1) The equation y = 3.5x represents the relationship between 2, the number of pounds of fruit,
and y, the price.
• Which ordered pairs represent an amount of fruit and the corresponding
price in the given equation? Choose ALL that apply.
(4, 14)
(6,9.5) (8,28)
(9.5,6)
(14,4)
(28,8)
Answer:
(4,14)
Step-by-step explanation:
plug in ordered pairs for the given equation and see which one works. ordered pairs are simply (x,y) and the equation just so happens to have x and y variables. when x in the equation equals 4 then 3.5*4 is equal to 14 which is the y value of the first ordered pair. try it with the others and they don't work. is x equaled 28 then 3.5*28 is 98 and that paired y is only 8 so no. do it with all ordered pairs if you must. it's an elimination game
The ordered pairs (4, 14), and (3, 28) satisfy the equation y = 3.5x.
What is an ordered pair?An ordered pair is made up of the ordinate and the abscissa of the x coordinate, with two values given in parenthesis in a certain sequence.
Pair in Order = (x,y)
x is the abscissa, the distance measure of a point from the primary axis x
y is the ordinate, the distance measure of a point from the secondary axis y
The given equation for the pounds of fruits 'x' and the total cost 'y' is,
y = 3.5x.
Now, The ordered pairs that satisfy the equation can be obtained by putting the value of 'x' and checking the corresponding 'y' value.
(4, 14).
y = 3.5×4.
y = 14. (satisfies).
Similarly,
(3, 28), also satisfies the equation y = 3.5x.

An ice cream factory makes 220 quarts of ice cream in 5 hours. How many
quarts could be made in 48 hours? What was that rate per day?
Answer:
2112 quarts in 48 hr
1056 quarts made per day
Step-by-step explanation:
to find out how many quarts in one hour divide 220 by 5
220÷5=44
then multiply by 24 to know how much quarts made per day
44×24=1056
then multiply by two to know how many quarts in 48 hours
1056×2=2112

if the diameter of the concentric circles as shown in the given figure are in the ratio 1:2:3 then find the ratio of the areas of three regions
Answer:
1 : 4 : 9
Step-by-step explanation:
Given the ratio of diameters = a : b , then
ratio of areas = a² : b²
Here ratio of diameters = 1 : 2 : 3 , so
ratio of areas = 1² : 2² : 3² = 1 : 4 : 9
A glider flies 13 miles north from the airport and then 24 miles diagonally southeast. Approximately how far west does the glider have to fly to return to the airport?
Answer:
20.2 miles
Step-by-step explanation:
This can be described by the three sides of a right angled triangle. Let the distance of the glider to the airport be represented by x, applying the Pythagoras theorem:
[tex]/hyp/^{2}[/tex] = [tex]/adj1/^{2}[/tex] + [tex]/adj2/^{2}[/tex]
[tex]/24/^{2}[/tex] = [tex]/x/^{2}[/tex] + [tex]/13/^{2}[/tex]
576 = [tex]x^{2}[/tex] + 169
[tex]x^{2}[/tex] = 576 - 169
= 407
x = [tex]\sqrt{407}[/tex]
= 20.1742
x = 20.2 miles
The glider has to fly 20.2 miles to return to the airport.
