Answer:
-13 = n - 4
Step-by-step explanation:
-13 is four less than a number n
so four less than n can be written as n - 4
-13 = n - 4
n= -9

Answer:
2pi, 4pi, 6pi, 8pi, 10pi, 12pi, 14pi, 16pi, 18pi, 20pi
Step-by-step explanation:
Formula used=2p*r
3.3^2 means 3.3 times itself 2 times or 3.3 times 3.3 or (use calculator)10.89
smaller powers (that's what 3.3^2 is, it means 3.3 to the second power) sometimes use different words to denote powers exg
x^2=x squared (square=2dimentionsl)
x^3=x cubed (cube=3 dimentionsl)
then x^4=x to the fourth, and so on
fifth, sixth, tecnth
Answer:
(a) x = 30°
(b) mRS = 30°
mST = 120°
mTU = 120°
mUR = 90°
Step-by-step explanation:
(a) In the picture attached, the diagram is shown.
Given that m arc RS = x, from the ratios:
m arc ST = 4x
m arc TU = 4x
m arc UR = 3x
The addition of the four arcs must be equal to 360°, then:
x + 4x + 4x + 3x = 360°
12x = 360°
x = 360°/12 = 30°
(b) m arc RS = x = 30°
m arc ST = 4x = 4*30° = 120°
m arc TU = 4x = 4*30° = 120°
m arc UR = 3x = 3*30° = 90°
