Answer : false
you can have both positive and negative residuals
Answer:
m = 116
x = 24
y = 76
z = 40
Step-by-step explanation:
For startes the interior angles of triangles always add up to 180 degrees.
That means....
73 + 83 + x = 180
z + m + x = 180
z + y + 64 = 180
Another important fact is that two angles that are intersected by a line in the case 64 and m always add up to 180 degrees.
So m + 64 = 180
Let's start with 73 + 83 + x = 180
If you add 73 and 83 you get 156
x + 156 = 180 then subtract 156 from both sides and
x = 24
Then use m + 64 = 180 subtract 64 from both sides and
m = 116
z + m + x = 180 become
z + 116 + 24 = 180
Add 116 and 24 and you get 140
z + 140 = 180 subtract 140 from both sides and
z = 40
Check to make sure m + x + z = 180
24 + 40 + 116 = 180
z + y + 64 = 180 becomes
y + 40 + 64 = 180
40 + 64 = 104 so
y + 104 = 180 subtract 104 from both sides and
y = 76
Congratulations you have found all of the angles!
Answer:
3+4
you can get positive
mulitply it
Step-by-step explanation:
Answer:
814.5 mg remain after 4 hours
Step-by-step explanation:
The multiplier of the original quantity is 1 -5% = 0.95 for each passing hour. The amount remaining after x hours is ...
y = 1000·0.95^x
For x=4, the amount remaining is ...
y = 1000·0.95^4 = 1000·0.81450625
y ≈ 814.5 . . . mg remain after 4 hours
