Answer:

48

Step-by-step explanation:

To solve this question will demand use of permutation :

Now, we have 5 single digit even numbers which are 0,2,4,6,8

Now, the hundredth place will be able to hold any digit except 0 because if it is done otherwise, it will make it a two digit number.

Also, the tens digit can now hold four digits as one digit is already placed in hundredth place.

Likewise, the unit digit can now hold any of the remaining three digits.

From the fundamental principle of counting, the required number of three digit numbers is :

4 x 4 x 3 = 48

A 208-yard-long road is divided into 16 parts of equal length. Mr.Ward paints a 4-yard-long strip in each part. How long is the
Andreas93 [3]

Answer:

Length of unpainted strip of each part of the road = 9 yard

Step-by-step explanation:

Total length of the road = 208 yard

When it is divided into 16 equal parts,

length of each part = \frac{208}{16}

                                 = 13 yard

Mr.Ward paints 4 yard long strips in each part .That is he does not completely paint the part but paints only a small section of each part.

Length of unpainted strip of each part of the road = length of each strip - length of strip painted by Mr.Ward

Length of unpainted strip of each part of the road = 13 - 4

Length of unpainted strip of each part of the road = 9 yard
