Answer:
- 83 1/3 ft wide
- 171 2/3 ft long
Step-by-step explanation:
Let w represent the width of the area. Then 2w+5 represents the length. The perimeter is twice the sum of length and width:
P = 2(L+W)
510 = 2(2w+5 +w) . . substitute given values
255 = 3w +5 . . . . . . divide by 2
250 = 3w . . . . . . . . . subtract 5
83 1/3 = w . . . . . . . . .divide by 3; the width of the area
2w+5 = 171 2/3 . . . . the length of the area
The fenced area is 83 1/3 ft wide and 171 2/3 ft long.
Answer:
168ft
Step-by-step explanation:
1/2(6)(4)=12
1/2(6)(4)=12
(9)(5)=45
(9)(5)=45
(9)(6)=54
12+12+45+45+54=168
Answer:16 and 1/2 feet
Step-by-step explanation:
Answer:
C) 1/ 12
Step-by-step explanation:
for a fair 6-sided die, for each independent roll, the possible number of outcomes is 1,2,3,4,5,6. I.e there are 6 possible outcomes
Also realize that there is only one "2" out of the 6 possible outcomes.
hence P(roll 2) = 1/6
Similarly, there are 3 odd numbers (i.e 1, 3, 5) out of the 6 possible outcomes
hence P(roll odd number) = 3 /6 = 1/2
P (roll 2 on first roll then odd number on second roll)
= P(roll 2) x P(roll odd number)
= 1/6 x 1/2
= 1/12
Easy, first turn the factions into deciamls, then so 1.16-7.8=6.64. So, 6.64
