Answer:

B) 243 km^3

Step-by-step explanation:

The formula for volume is Length x width x height, so we must find those values. By looking at the shape, the length is 9 km, width is 9 km, and height is 3 km, and after substituting these values in the equation, we get 9 km x 9 km x 3 km. When multiplied, it equals to 243 km^3, so the answer for the volume of the solid is B) 243 km^3.

Hope this helped somewhat! :P

I think just by just doing the basic volume formula of h•w•l so 3•9•9

Jason is packing a large box with smaller shoe boxes. The larger box has a volume of 5832 cubic inches. Each shoebox measures 12

neonofarm [45]

Volume of large box = 5832 in^3
Volume of shoe box = 12*6*5=360 in^3

Maximum number of shoe boxes that might fit in the large box
= 5832/360 = 16.2, or 16.

However, we have to verify the dimensions to make sure each side fits.
For example, if the large box is 18x18x18=5832 in^3,
then we can only fit, along each dimension:
18/12=1.5 => 1 (6 inches remaining)
18/6=3 => 3 (0 inches remaining)
18/5=3.6 => 3 (3 inches remaining)
That make 9 boxes.
However, we still have a gap of 6 inches that we can fit shoe boxes vertically, i.e.
6/6=1 row
18/12=1 row
18/5 = 3 rows
That will fit 3 more boxes for a total of 9+3=12 boxes (instead of 16 boxes).

So 16 is the MAXIMUM number of boxes (according to volume).
The actual number of boxes will depend on the dimensions of the large box. 18x18x18 was given just as an example.

If further explanations are needed, please post in comments.

What is the property of 7+(a+b)=7+a)+b

-BARSIC- [3]

The associative property of addition says that when every operation is addition, you can group numbers however you like and choose which pair of numbers to add first; you can move parentheses without changing the answer.

Alex and bob are playing 5 chess games. Alex is 3 times more likely to win than bob. What is the probability that both of them w

givi [52]

Answer:

12.2%

Step-by-step explanation:

Lets firstly find out the probabilities for Alex and Bob. We know that the prb that Alex wins is 3 times the prob for Bob, so:

P(A) = 3P(B)

And, as these values are probabilities they must sum 1:

P(A) + P(B) = 1

Replacing the first equation in the second:

3P(B) + P(B) = 1

4P(B) = 1

Dividing both sided by 4:

4P(B)/4 = 1/4

P(B) =1/4

So, the probability for Bob is 1/4. Then the probability for Alex is 3*1/4 = 3/4

Now we have to find the probability that both win at least two games. Lets think about the possible combination of cases. As they play 5 games and both have to win at least to there is a remaining game that cane variate, this is, can be won by Alex or Bob. So, we can have:

AABBB

AABBA

Where A is "Alex win" and B is "Bob win" (here we do not pay attention to the order).

Thus, we have to find the probability that Alex wins 3 games and Bob 2 games, and the probability that Alex wins 2 games and Bob 3 games. As the games are independent, i.e., the result of one games does not affect the followings we can just multiply the probabilities:

P(3A and 2B) = (3/4)*(3/4)*(3/4)*(1/4)*(1/4) = 0.42*0.06 = 0.026

P(2A and 3B) = (3/4)*(3/4)*(1/4)*(1/4)*(1/4) = 0.56*0.016 = 0.096

So,

P (at least 2) = P(3A and 2B) + P(2A and 3B) = 0.026 + 0.096 = 0.122 = 12.2%
