Answer:
A.
Step-by-step explanation:
The center is at (0, -6) so the equation is:
(x - 0)^2 + ( y + 6)^2 = r^2
x^2 + (y + 6)^2 = r^2
r^2 = 11
Answer is x^2 + (y + 6)^2 = 11.
Answer:
Elevation in boiling point is mathematically expressed as
ΔTb = Kb X m
where Kb = boiling point elevation constant = 2.53°c/m (for benzene)
m = molality of solution = 3.47 m (given)
∴ ΔTb = 2.53 X 3.47
= 8.779 oC
But, boiling point of benzene = 80.1 oC
∴ Boiling point of solution = 88.879 oC
Now, Depression in freezing point = ΔTf = Kf X m
where, Kf = freezing point depression constant = 5.12°c/m (for benzene)
∴ ΔTf = 5.12 X 3.47
= 17.766 oC
But freezing point of benzene = 5.5 oC
∴ Freezing point of solution = -12.266 oC

ANSWER IS
$131.35
If 1 liter of milk is $17 3/4 we just need to find the cost for 7 2/5.
Since we’re working with money we have to turn the $17 3/4 and 7 2/5 into a decimal so its ($17.75) and 7.40
Anyways we multiply those numbers to find the cost of 7 2/5 liters
( 17.75 x 7.40) and the answer is $131.35
Answer:
The value of x is 28°
Step-by-step explanation:
Here, In a given fugue, a = 40°
We know that, A straight angle is an angle equal to 180°
So,
a + 2x + 3x = 180°
40° + 5x = 180°
Subtract 40 from both side
40° - 40° + 5x = 180° - 40°
5x = 140°
Divide by 5 from both side
5x/5 = 140°/5
x = 28°
Thus, The value of x is 28°
<h3 /><h3>
<u>FOR</u><u> </u><u>VERIFICATION</u><u> </u><u>ONLY:</u></h3>
<u>a + 2x + 3x = 180°</u>
40 + 2(28) + 3(28) = 180°
40° + 56° + 84° = 180°
180° = 180°
Hence, L.H.S = R.H.S
