Step-by-step explanation:
Answer:6
Step-by-step explanation:
2.5 x 2.5 x 2.5 =15.625 (volume of one cube)
7 x 5 x 3 =105 (volume of cuboid)
105/15.625 =6.75
she cant make 3/4 of a cube therefore the greatest amount of cubes she can make is 6.
If you are just using the digits from 1 to 6, the answer would be 6*5*4*3*2*1 = 720, because you have 6 choices for the units digit, and then 5 choices left for the tens, and then 4 choices left for the hundreds and so on. Similarly, if all the digits from 1 to 9 were allowed (with no digit repeated), then the answer would be 9*8*7*6*5*4 = 60480.
The tricky part comes when the digit 0 is allowed: suppose that you wanted to form a 6-digit number using digits from 0,1,...,9 without repeating a digit. Then 0 could not be the leftmost digit. So, starting from the left, you would have 9 choices for the leftmost digit (not allowing 0), then 9 choices again for the next digit (0 is now allowable but not the previous digit), then 8 choices for the next digit and so on, for a result of 9*9*8*7*6*5 = 136080.
At first convert it to: (x^2 + 9x +20)/x+5
then analyze it:
multiply=20
addition=9. ==>so we must to choose 4 and 5
(4)(5)=20
4+5=9
so we have : (x+4)(x+5)/(x+5) =x+4
