Answer:
8
Step-by-step explanation:
Measure of one interior angle of a regular polygon of n sides:
(n - 2)180/n
Measure of one exterior angle of a regular polygon if n sides:
360/n
"the interior angle is thrice the exterior angle"
(n - 2)180/n = 3 * 360/n
(n - 2)180 = 3 * 360
n - 2 = 3 * 2
n = 8
The number of sides is 8.
Answer:
Your answer would be 61 in.
Step-by-step explanation:
Hi!
The correct answer is B. The value of M is a product of N and a factor that does not depend on N.
That is true because the relation is : M(t) = N * (1+r)^t , N is N and (1+r)^t is a factor that does not depend on N.
Also, because none of the other answers is true, it makes easier for B to be the one true answer, explanation:
A. The initial value is (1+r) - WRONG, the initial value is N, it says that
C. The function is linear - WRONG, we have exponential growth here, because of the factor (1+r)^t
D. N increases each month - WRONG, N is the initial number of members and it does not change.
Hope this helps!
Steps to solve:
1. 3/4+1/5
Change both denominator to the same- 4*5=20
So far its: ?/20 + ?/20
2. For the first fraction (3/4) we do 3*5=15
Because when we found the denominators we multiplied each denominator by each other. For the second one we do pretty much the same. We do 1*4=4.
3. The final equation is 15/20 + 4/20.
Now add both numerators, which is 19. You leave the denominator as it is. So the final fraction is 19/20.
4. Next to get a full fraction from 19/20 you need 1/20 to get 20/20=1.
On the calculator you type in: 1/20*1800
OR... 1800/20
OR... (18/2)100
So the final answer is 90. 1800/20=90
= 90 members under the age of 25.
