Angle ∠ A = α = 44.049° = 44°2'55″ = 0.769 rad
Angle ∠ B = β = 52.617° = 52°37' = 0.918 rad
Angle ∠ C = γ = 83.335° = 83°20'4″ = 1.454 rad
Answer:
-3/19
Step-by-step explanation:
Given data
We have the coordinates
(12, 2), (-7,5)
x1=12
y1=2
x2=-7
y2=5
The expression for the slope is given as
Slope= y2-y1/x2-x1
Substiute
Slope= 5-2/-7-12
Slope= 3/-19
Hence the slope is -3/19
Answer:
A
Step-by-step explanation:
b must always be greater than 0 since 12b-15 must always be greater than 21. You can simplify the ineqaulity to see things easier; 12b>36. Again, this ineqaulity can be simplified; b>3. A is the closest answer here, but there should be an open interval at 3 for A to be correct.
Answer:
The number of bottles recycle by Alice is 21.
Step-by-step explanation:
Given:
Mike and Alice recycled 147 bottles altogether. Mike recycled 6 times as many bottles as Alice.
Now, to find the quantity of bottles Alice recycle.
Let the number of bottles recycle by Alice =
.
And the number of bottles recycled by Mike =
.
So, according to question:

⇒
<em>Dividing both sides by 7 we get:</em>
⇒
.
Therefore, the number of bottles recycle by Alice is 21.
