The solution to the system of equations is (-1/3, 11/3)
Area = length x height
225 = length x 9
length = 225 ÷ 9 = 25 feet
Perimeter = 9 + 9 + 25 + 25 = 68 feet
(White cars)9+1(yellow cars
40 divided by 10 is 4
4 is the amount of yellow cars so take that away from 40
Your answer is 36
Answer:
if you can buy full bags then i guess $15
Step-by-step explanation:
length is 6 width is 2
6x2=12
12/5=2.4
you would need 2 2/5 bags but if you can't buy less than 1 bag then 3
7. tails, odd, 4
P(tails) = 1/2
P(odd) = 3/6 = 1/2
P(4) = 1/6
P(tails then odd then 4) = (1/2)×(1/2)×(1/6) = 1/24 ≈ 0.041666
Answer: 1/24, 4.2%
8. tails, 6 or 1, 3
P(6 or 1) = 2/6 = 1/3
P(3) = 1/6
P( tails, 6 or 1, 3) = (1/2)(1/3)(1/6) = 1/36 ≈ 0.027777
Answer: 1/36, 2.8%
9. heads, not 2, even
P(heads) = 1/2
P(not 2) = 5/6
P(even) = 1/2
P(heads, not 2, even) = (1/2)(5/6)(1/2) = 5/24 ≈ 0.208333
Answer: 5/24, 20.8%
