21.27*40= Annual premium is 850.8 51% of 850.8 is 433.9 ---> semi annual his quarterly is 26% of 850.8 so 221.2 and finally his monthly premium is 9 percent of 850.8 so it's 76.57
Answer:
= 4n - 11
Step-by-step explanation:
These are the terms of an arithmetic sequence with n th term
= a₁ + (n - 1)d
where a₁ is the first term and d the common difference
d = - 3 - (- 7) = 1 - (- 3) = 5 - 1 = 4
and a₁ = - 7, hence
= - 7 + 4(n - 1) = - 7 + 4n - 4 = 4n - 11
The value of 'x' is 10°
<h3>How to determine the angles</h3>
We have that supplementary angles sum up to 180
M∠A = (6x +4)° and m∠B = (10x + 16)°.
Then,
6x + 4 + 10x + 16 = 180
Collect like terms
16x + 20 = 180
16x = 180 - 20
16x = 160
x = 160/ 16
x = 10°
Thus, the value of 'x' is 10°
