Answer:
Step-by-step explanation:
To start of u have to subtract 150 with 180 which is 180 (cuz its a straight line and E to get angle S
Now that we know that 180-150= 30
We add S and R then subtract by 180
so 80+ 30= 110
then we said subtract 180
180-110= 70
Now we know that angle Q is 7-
Then the bottom is RS & SE (NOT REALLY SURE)
It is a Remote Interior Angle
IF RIGHT PLZ GIVE BRAINLIEST
THANK U
HAVE A GREAT DAY AND BE SAFE :)
XD
If im right give me brainliest
Answer: 154
Step-by-step explanation: 22 represents days 7 represents miles he walks a day i think you to have to multiply. 22 times 7 is 154
The slope of line T is -1/5, because perpendicular lines have opposite reciprocal slopes, meaning the opposite sign (positive or negative) and flipped (whole number becomes a fraction).
<span>Answer:
MgF2 ====⇒ Mg+2 + 2F-
Ksp = [Mg+2][F-]^2
Let S = molar solubility of MgF2
[Mg+2] = S ; [F-] = 2s
Since the [F-] is initially 0.40 M, then [F-] = 0.40 + 2S
6.4 x 10^-9 = (S) (0.40 + 2S)^2 ; one can neglect the 2S in the 0.40 + 2S expression since it is very, very small compared to the 0.40 already present.
6.4 x 10^-9 = S(0.40)^2
S = 4.0 x 10^-8
Molar solubility = 4.0 x 10^-8</span>
