Answer:
32. <u>40%</u>
33. <u>15%</u>
34. <u>1/5</u>
35. <u>1/4</u>
Step-by-step explanation:
<u>Question 32</u>
- % Hens = No. of hens / Total poultry
- % Hens = 72 / 27 + 72 + 45 + 36
- % Hens = 72 / 180 = 2/5
- % Hens = <u>40%</u>
<u>Question 33</u>
- % Geese = No. of geese / Total
- % Geese = 27/180
- % Geese = 3/20
- % Geese = <u>15%</u>
<u>Question 34</u>
- % Ducks = No. of ducks / Total
- % Ducks = 36/180
- % Ducks = <u>1/5</u>
<u>Question 35</u>
- % Turkeys = No. of turkeys / Total
- % Turkeys = 45/180
- % Turkeys = <u>1/4</u>
Step 1
find the inverse
<span>exchange x for y and y for x
y=2x
then
x=2y---------> clear y
y=x/2
</span><span>f−1(x)=x/2
for x=32
</span>f−1(32)=32/2----------> 16
<span>
the answer is 16

1) 7, 11, 17, 25, 35
2) 6, 12, 22, 36, 54
6) The nth term is T= n^2 +4n -1
7) The nth term is T= n^2 + 3n
8) The nth term is T= 2n^2 + 2n + 5
I‘ll try to do the others, I’ll write the solutions in the comments of my answer
Answer:
Subtracting polynomials is quite similar to adding polynomials, but there are those pesky "minus" signs to deal with. If the subtraction is being done horizontally, then the "minus" signs will need to be taken carefully through the parentheses
Step-by-step explanation:
Answer:
-6
Step-by-step explanation:
Some nasty order of operations coming up.
Firstly, deal with that squared:
-12 / 3 * (-8 + 16 - 6) + 2
Simplify the bracket:
-12 / 3 * 2 + 2
Simplify -12 / 3:
-4 * 2 + 2
Simplify -4 * 2:
-8 + 2
Simplify:
-6
