So when you solve, it’s going to be y=60x-30. So on the graph, you start at -30 and add 60 up and one box over.
146 or 27 because 27 with 73 = 100% or 219-73=146
Answer:
our answer will be in quadrant 1 only.
Step-by-step explanation:
From the
cos−1(1) we have the side adjacent to ∠θ=1 and the side hypotenuse=2 . So this is a 30∘−60∘−90∘ triangle and θ=60∘therefore the opposite to ∠θ=√3.
Note that from the restrictions for the range of inverse circular functions cos−1x is restricted to quadrants 1 and 2 and since the argument is positive 12 our answer will be in quadrant 1 only.
The weight of copper is 8 1/10 in the gram.
I add 2x + 3x to get 13 1/2 to find what x is to multiply back into the ratio to find the weight of copper.
So the equation is 5x=13 1/2
Solving it we get x=27/10.
Now we multiply 27/10 * 3 to find the weight of copper. The answer is 81/10, simplifying into 8 1/10. This means that the weight of Zinc is 5 2/5, we get this by subtracting 13 1/2 to 8 1/10.
Hope this helps!
