Answer:
Well you can start by dividing 20 by 2 because that would give you the half that you finished in class 24 divided by 2 =12 if you finish four more you wound have 12-4=8 you have 8 problems left and now you have to find the fraction so start with 8/24 and then simplify your answers would be 1/3

Answer:

Step-by-step explanation:
We are given the two functions:

And that:

With the given conditions that (1, -40) and (-1, 24) satisfy the new function, we want to determine functions <em>f</em> and <em>g</em>.
First, find <em>h: </em>
<em />
<em />
Because (1, -40) and (-1, 24) are points on the graph of <em>h</em>, we have that h(-1) = 40 and h(-1) = 24. In other words:

And:

Solve the system of equations. Adding the two equations together yield:

Solve for either <em>m</em> or <em>n: </em>
<em />
<em />
Substitute this into one of the two equations above and solve:

Therefore:

Solve for <em>m: </em>
<em />
<em />
Hence, the values of <em>n</em> and <em>m</em> are either: 2 and 2, respectively; or 1 and 0, respectively.
In conclusion, functions <em>f</em> and <em>g</em> are:

Answer:
∠ PRQ = 55°
Step-by-step explanation:
The angle subtended at the centre by an arc is twice the angle subtended at the circumference by the same arc, thus
∠ PQR = 0.5 × 110° = 55°
