1hr/3600sec=15hr/x
(3600sec)(15hr)=(1hr)x
x=54000seconds
15 hours is 54000 seconds
Answer:
(0,-9)
Step-by-step explanation:
The equation of a circle is written in the form
(x-h)^2 + (y-k)^2 = r^2 where (h,k) is the center and r is the radius
Rewriting
x² + (y + 9)^2 = 25
(x-0)² + (y - - 9)^2 = 5^2
We find the center is (0,-9) and the radius is 5
Answer:
B = 22
C = 122
D = 36
Step-by-step explanation:
The angles of a triangle add to 180. Take the measure of each angle add them together. Set them equal to 180.
2x + x + 4 + 7x - 4 = 180
10x = 180
x = 18
To find each angle, substitute x = 18.
Angle B is 18 + 4 = 22
Angle C is 7(18) - 4 = 122
Angle D is 2(18) = 36
Answer:
X<8
Step-by-step explanation:
-3 > X-11
= -3 +11 > X
= 8 >X
X<8
