Answer:
1) a = 110
2) b = 65
3) c = 115 d= 65 e = 115
How I found the last one?
The whole thing equals 360.
d is equal to 65 so I added those together.
That equals 130. So i subtracted that from 360.
I got 230. Next, I divided that by 2 to get the final 2 angles.

Answer:
13:12, 13 to 12, or 13/12
Step-by-step explanation:
520:480
Divide both numbers by GCF (40)
13:12
Part A:
[$25-( $0.50×22)]÷$2=n
Part B:
[$25-($0.50×22)]÷$2=n
[$25-($11)]÷$2=n
[$14]÷$2=n
7=n
Part C: Brandon purchased 7 meals last month.
Answer is 0.7 degrees celcius per minute
Explanation:
given that T(t) = 42-0.7t
We have to find the rate of drop of temperature.
For that we find drop of T in 1 minute
Consider T(t) for t minutes and t+1 minutes
T(t+1) = 42-0.7(t+1)
T(t) = 42-0.7t
Difference i.e. drop in temperature in one minute
= T(t+1)-T(t)
= 42-0.7(t+1)-(42-0.7t) =-0.7
Hence drop per minute = 0.7 degree celcius.
