30+60+90=180
55+35+80=180

Find the number of four-digit numbers which are not divisible by 4?
SOVA2 [1]

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

Which statement best describes Marcos equation
satela [25.4K]
Marco's equation is correct.  Cosine is an even function, which means that for every x, f(-x) = f(x).  In other words, you get the same answer for a negative value that you would for its corresponding positive value.
