Hey mate ,
here is your answer
**********************
The average between any two rational numbers is also rational.
(7.7 + 7.9)/2 = 7.8
7.8 is rational because it can be written as a fraction with integer numerator and denominator (39/5) and it is also a terminating decimal.
Complementary angles add up to 90°. The complement of a 27° angle is 90°-27°= 63°.
Supplementary angles add up to 180°. The supplement of a 27° angle is 180°-27°=153°
P= Price
O= Original price
N= Number of days
P= O - (N * 0.02)
EXAMPLE:
O= 50
N= 1 day
P= 50 - ( 1* 0.02) = 49.98
N= 2 days
P= 50 - ( 2* 0.02) = 49.96
N= 3 days
P= 50 - ( 3* 0.02) = 49.94
N= 4 days
P= 50 - ( 4* 0.02) = 49.92
N= 5 days
P= 50 - ( 5* 0.02) = 49.90
N= 6 days
P= 50 - ( 6* 0.02) = 49.88
N= 7 days
P= 50 - ( 7* 0.02) = 49.86
Answer:
-27
Step-by-step explanation:
I believe it's -27, because 12+15 =27. I made it negative because the temperature is decreasing, not increasing.
Answer is 7pi (you had my explanation earlier)
