Answers: 13) b 14) c 15) c 16) c

Step-by-step explanation:

13)

The possible options are: BBB, BBG, BGB, GBB = 4 : 8

Simplified (divide by 2) is 1 : 2

14)

Odd: 1, 3, 5, 7, 9 = 5:10

Prime: 2, 3, 5, 7 = 4:10

≤ 5: 0, 1, 2, 3, 4, 5 = 6:10 This has the highest probability!

÷ 3: 3, 6, 9 = 3:10

15)

There are 8 - 3 sections that are not red and 8 total sections

(8 - 3) : 8 = 5:8

16)

Reese has 15 votes and there are 15 + 13 + 12 total votes

15 : (15 + 13 + 12) = 15 : 40

Simplified (divide by 5) is 3 : 8

Answer:

a^3b^4

Step-by-step explanation:

You have 3 a's, so that would be

$a^{3}$

and you have 4 b's so that would be

$b^4$

so putting it together gives you

$a^3b^4$

You have a 1200-foot roll of fencing and a large field. you want to make two paddocks by splitting a rectangular enclosure in ha

romanna [79]

Let width = w
Let length = l
Let area = A
3w+2l=1200
2l=1200-3w
l=1200-3/2
A=w*l
A=w*(1200-3w)/2
A=600w-(3/2)*w^2
If I set A=0 to find the roots, the maximum will be at wmax=-b/2a which is exactly 1/2 way between the roots-(3/2)*w^2+600w=0
-b=-600
2a=-3
-b/2a=-600/-3
-600/-3=200
w=200
And, since 3w+2l=1200
3*200+2l=1200
2l = 600
l = 300
The dimensions of the largest enclosure willbe when width = 200 ft and length = 300 ft
check answer:
3w+2l=1200
3*200+2*300=1200
600+600=1200
1200=1200
and A=w*l
A=200*300
A=60000 ft2
To see if this is max area change w and l slightly but still make 3w+2l=1200 true, like
w=200.1
l=299.85
A=299.85*200.1
A=59999.985
