Vertical angles are congruent. 3x+15 = 2x-10. x = -25
(x+8)^(2) + (y+9)^(2) = 169
(x+8)^(2) + (y+9)^(2) = 13^2
h = -8
k = -9
r = 13
answer
A. center (-8,-9)
radius = 13
--------------
(x-7)^2 + y^2 = 225
(x-7)^2 + y^2 = 15^2
h = 7
k = 0
r = 15
answer
B. center (7,0)
radius = 15
Given : supply voltage = 120V;60 Hz
Inductive Reactance 
Ω
The inductive reactance is given by the formula, 
, where L is inductance and 
is given by formula, 
Apply this, we can say that, 
Answer: The Mean absolute deviation is 5. The mean is 10.
2 is 8 away from the mean.
5 is 5 away from the mean.
9 is 1 away from the mean.
10 is 0 away from the mean.
17 is 7 away from the mean.
19 is 9 away from the mean
Step-by-step explanation:
Hope this helps!
pls mark brainliest :)
Let X = science homework.
Then math homework would be 3x ( three times as long).
Now you have math plus science = 64 minutes:
x + 3x = 64
Combine like terms:
4x = 64
Divide both sides by 4:
x = 64 / 4
x = 16
He spent 16 minutes on science and 48 minutes on math.
