To start, ABCD(D)=DCBA means that D×A=D because they're all single digit numbers and since nothing carries over to make DCBA a 5 digit number A must be 1. If A is 1 for ABCD(D)=DCBA that would mean D^2 is a number ending in 1 so the only possibility for D is 9. Since D is 9, D×B has to be less than 10 because we know nothing carries over to the D×A (9×1) so B has to be 0. So far we have 10*9(9)=9*01 and since D×D (9×9) is 81 we need a number divisible by 9 that ends with 2 to add to the 8 digit which the only possibility is 72 from 8×9. SO A=1, B=0, C=8, D=9
1089(9)=9801
Answer:
Part a) The height that the liquid forms equals 2.56 feet.
Part b) The number of trucks required are 361.
Step-by-step explanation:
When all the liquid mixture is spilled from the storage tank it will accumulate over the floor space.
Thus we infer
where
is spilled volume of mixture =
is accumulated volume over the floor
Since the floor is smooth thus we conclude that the accumulated volume will form a prism of liquid with height 'h'
Thus
Equating both the volumes we get
Thus the height formed by the liquid equals 2.56 feet.
Part b)
We know that the basic relation between density, mass and volume is
Since it is given that the density of the liquid is 112% the density of water thus we have
Thus the weight of the volume of liquid is
Now since it is given that 1 truck can carry 9000 kg of liquid thus by proportion the number of trucks need to carry 3248000 kilograms of liquid equals
Answer: 8512
Step-by-step explanation: if he makes 3% a year more for 4 years we have to add 3%+3%+3%+3%=12% and add it to 7600 so 7600+12%=8512
Answer:25x+10x=$2.25
25=quarters and 10=dimes x is what we will plug in (how many coins Michael has for each type of coin) and $2.25 is how much money he has all together
Step-by-step explanation:
i used a money calculator and this is what it came too.
Answer:
40 pigs
Step-by-step explanation:
6*5=30
200-30=170
170/5=34
34+6=40 pigs
to check your answer
40*5=200
