Answer:
the polygon has 10 sides
Step-by-step explanation:
Recall that the sum of the interior angles of a polygon of N sides is given by the formula:
Sum = (N - 2) * 180
and that the sum of the exterior angles of any polygon is always 360 degrees.
Since we are told that the sum of the interior angles is 4 times the sum of the exterior angles, we set the following equation:
(N - 2) * 180 = 4 * 360
Solving for N, we start by dividing both sides by 180:
(N- 2) = 4 * 360 / 180
N - 2 =4 * 2
N - 2 = 8
N = 10
So the polygon has 10 sides
Answer:
23 años
Step-by-step explanation:
Para resolver la situación, consideremos que x es la edad de la persona. Sabemos que dentro de seis años esta tendrá el doble de la edad que tenía hace cuatro años. La edad dentro de 6 años se puede expresar como x+6 y esto será igual al doble de la edad que tenía hace cuatro años, lo que se puede expresar como 2(x-4). De acuerdo a esto:
x+6=2(x-4)
x+6=2x-8
6+8=2x-x
x=14
Ahora que sabemos que la edad de la persona es 14 años, le sumamos 9 y esto da como resultado 23 y esta es la edad que la persona tendrá en 9 años.
Answer:
The car was moving approximately at a speed of 37.74 miles per hour.
Step-by-step explanation:
We are given the following in the question:
The stopping distance of a car is given by
where d is the stopping distance in feet and r is speed of the car in miles per hour.
The stopping distance is 75 feet, we have to find the speed of the car,
Putting d = 75 in the equation, we get,
Thus, the car was moving approximately at a speed of 37.74 miles per hour.
