Concentric circles are circles that share a common center with each other.
There are 3 circles in this diagram. There is a circle with center A, a circle with center B, and a circle with center C. There are no circles that share the same center, as all circles have their own centers.
There are no concentric circles shown.
11, 13 and 15
note that consecutive odd integers have a difference of 2 between them
example : 1, 3 , 5
let the 3 consecutive integers be n , n+ 2, n + 4
The sum of the 3 integers divided by 3 gives the average, thus
= 13
= 13 (multiply both sides by 3 to eliminate fraction )
3n + 6 = 3 × 13 = 39 ( subtract 6 from both sides )
3n = 39 - 6 = 33 ( divide both sides by 3 )
n = = 11
the integers are 11, 11 + 2, 11 + 4 = 11, 13, 15
Answer:
the answer to the question is 8
Answer: f(x)=200•(0.85)^x
Step-by-step explanation:
C(t) is the actual value of the function at time t
Co is the initial value of C at t=0
r is the decaying rate, expressed in decimal
Depreciation is often modeled as an exponential decay function. Since Jim bought a skateboard for Co=$200, its value will depreciate by r=15% = 0.15 each year since buying it.
Answer:
x=36
2x=72
4x=144
Step-by-step explanation:
Remember that the sum of all the inside angles of a triangle = 180
so angle E is 180-2x
and angle F is 180-4x
If you add angles E, F, and G, they need to add to 180.
substituting, we get 180-2x + 180-4x + x = 180.
Simplifying this, we get 180-5x = 0
and x=180/5 = 36
so if x=36, then 2x=72 and 4x=144
