Find the number of four-digit numbers which are not divisible by 4?

Mathematics
1 answer:
SOVA2 [1]3 years ago
3 0

Answer:

6750

Step-by-step explanation:

4 digit numbers are 1000,1001,1002,...,9999

let numbers=n

d=1001-1000=1

9999=1000+(n-1)1

9999-1000=n-1

8999+1=n

n=9000

now let us find the 4 digit numbers divisible by 4

4| 1000

______

| 250

4 |9999

  _____

  | 2499-3

9999-3=9996

so numbers are 1000,1004,1008,...,9996

a=1000

d=1004-1000=4

let N be number of terms

9996=1000+(N-1)4

9996-1000=(N-1)4

8996=(N-1)4

N-1=8996/4=2249

N=2249+1=2250

so number of 4 digit numbers not divisible by 4=9000-2250=6750

AleksAgata [21]
The problem says that the expression (3x + 5)(5x − 1) <span>represents the area of the floor of the building in square meters. Therefore,  to solve this problem you have to follow the proccedure shown below.

 1. First, to simplify the expression (3x + 5)(5x − 1) you must apply the distributive property. Then, you obtain:

 15x</span>²-3x+25x-5

 2. Then, you have:

 15x²+22x-5

 3. As you can see, the correct answer is the last option:  15x²+22x-5

Susan keeps track of the high and low temperatures every day for a week. The following table shows her data what is the average
uysha [10]

Answer:

10.75

Step-by-step explanation:

To get the average, we always SUM UP all the numbers and divide by the number of numbers.

We do this for "change" row since we want average of "change".

Let's add up all the changes:

11 + 12 + 10 + 10 + 11 + 10 + 11 = 75

How many numbers are there?

There are 7 numbers

Now, the average:

Average = Sum/Number of Numbers

Average = \frac{75}{7}=10.75

The average = 10.75
