How many odd integers are there between 101 and 999 have distinct digits?
guapka [62]
Every number will have only 3 digits. In the ones place, there are 5 choices. For every choice of digit made in the ones place, there are 8 possible choices for the hundreds place (you can choose from 1-9, omitting whatever is used in the ones place), and there are 8 possible choices for the tens place (you can choose from 0-9, omitting whatever has already been used elsewhere).

So there are 7\cdot8\cdot8=320 such numbers.

AlladinOne [14]

Answer:

4240 inches²

Step-by-step explanation:

In order to find the amount of film needed, we have to find the surface area of this cuboid.

  • Formula to Find Surface Area of Cuboid: 2(wl+hl+hw), where w = width, l = length, and h = height.

Now, let's solve!

  • 2(36*25+20*25+20*36)  
  • 2(900+500+720)
  • 2(2120)
  • 4240

Therefore, the answer is 4240 inches².

1. Is the following system consistent or inconsistent?
Sidana [21]

Answer with Explanation:

If a consistent system has an infinite number of solutions, it is dependent . When you graph the equations, both equations represent the same line.

If a system has no solution, it is said to be inconsistent . Represent parallel lines.

1)   8x + y + 4 = 0  

       y = -8x - 4

If we solve equation 8x + y + 4 = 0  for y, we get

y = -8x -4

So, both equations are same. That means both lines are same. So infinite many solutions.

System is consistent


2) Both line slope are same and parallel to each other.

So,  no solution

System is  inconsistent.


3) Both equation represent the same line. So, infinite many solution.

System is consistent.


4)  Both lines are intersect at a point.

Intersection point is (7,0).


5) Both lines are parallel. So, no solution.

System is inconsistent.
