Answer:
a)
(i) 43, 56
(ii) -1,3
b)-27
c) -21 +4n
Step-by-step explanation:
For a,i, you can see that it decreses by 7 each time so you subtract 7 from 50 to get 43, then you subtract 7 from that to get 56. For a,ii it increases by 4 each time so you add 4 to -5 to get -1, then add 4 to that to get 3. For b, because it is the 15th term you are looking for, you can plug 15 into the equation as n so 78-7n to 78- 7*15, 78-105, -27. For c, you know that each time it increases by 4, so you know you add 4n, and then for the base, you have to find the term before -17 so you subtract 4 to get -21. Put it together and get -21+4n.
Using trial and error method,
(26*2)+(17*4)=120 legs

Answer:
it is 3
Step-by-step explanation:
it plotted the points on a graph and it is a vertically stretched 3rd degree function
We conclude that 375 portions can be sold.
<h3>
How many portions can be sold?</h3>
We know that 500 portions have been ordered, but only 5/6 of that was delivered, so the number of delivered portions is:
p = (5/6)*500 = 416.6
Which we can round to the next whole number, 417.
Now we know that 10% of these are given to the players and staff, then the number of portions that can be sold is the 90% of 417, which is:
N = 417*(90%/100%) = 417*0.9 = 375
We conclude that 375 portions can be sold.

Answer:
1: The one vertical from 104° is 104°
2:The one near the corner is 20°
3: The two angles right next to 104° are 76°
Step-by-step explanation:
1: Vertical angle are always equal to each other.
2: All sides of the triangle must equal 180° in all. If you add 56° + 104° it equals 160°. Now subtract 180° - 160°. You get 20°.
3: All straight angles equal 180° in all. So, if you subtract 180° from 104° you will get 76°. And again, these two angles are vertical so they will both be 76°.
