Answer:
C
Step-by-step explanation:
the sum of the exterior angles of a polygon = 360°
sum the 4 exterior angles and equate to 360
8x + 9x + 5 + 5x + 4 + 9x + 3 = 360 , that is
31x + 12 = 360 ( subtract 12 from both sides )
31x = 148 ( divide both sides by 31 )
x ≈ 11.23 ( to 2 dec. places )
then exterior angle at B is
9x + 3 = 9(11.23) + 3 ≈ 104° → C
Answer:
Rate of change = 3/2
Step-by-step explanation:
Use a function with an interval:
f(x) = x^2, [2,3]
3-2= -3x-x
1 = -4x
x = -1/4
Yes it is possible
A. F(x)= 3x+6 =12
3x = 12-6
3x = 6
x=2
B. x=10, f(x)= 3*10+6 = 30+6 = 36
C. f(x) = 3x+6 = 6
3x = 6-6
3x=0
x=0
D. x=5, f(x) = 3x+6 = 3*5+6 = 15+6 = 21
Answer:
<em>The difference is 30 hours</em>
Step-by-step explanation:
<u>Proportions</u>
Safie can write a minimum of 5 questions per hour and a maximum of 11 questions per hour.
To write 275 she takes a maximum of 275/5=55 hours and a minimum of 275/11=25 hours.
The difference is 55 hours - 25 hours = 30 hours
