Answer:
answer D
Step-by-step explanation:
V=L*W*H=1 ==> L=1,W=1,H=1
A:
L-> L+2=1+2=3
W -> W+2 = 1+2=3
H -> H+2=1+2=3
V=3*3*3=27 not the doubled of the volume's cube
A is false
B:
H -> H+2=1+2=3
V=1*1*3=3 not the doubled of the volume's cube
B is false
C:
H -> 2*H=2*1=2
L -> 2*L=2*1=2
W -> 2*W = 2*1=2
V=2*2*2=8 not the doubled of the volume's cube
C is false
D:
H-> H*2=1*2=2
L=1
W=1
V=1*1*2=2 is the doubled of the volume's cube
D is true
Since 1sand=3.5compost you can set up the ratio 1/3.5 or 1 sand for every 3.5 compost. If you change the number of sand to three, then you multiply the top by three since 1*3=3. To keep the mixed number equal you would have to multiply the bottom number by three as well. This means that you can multiple all the sand by 3.5 to get how much compost is needed.
Answer:
10
, or 17.32050
Step-by-step explanation:
Everything is in million acres, so we can just drop that while we work it out but just remember we have to add it back on at the end of the problem.
First year 3.42
Second year 8.71
Third year ???
Total 21.46
So...
3.42 + 8.71 + ? = 21.46
12.13 + ? = 21.46
? = 21.46 - 12.13
? = 9.33
The 3rd year 9.33 million acres were burned
*Note I put a ? for the unknown. I could have used x or y or anything else.
