Answer: 3,000,000+200,000+90,000+8,000+70+6

Answer:

Answer:

3,000,000 + 200,000 + 90,000 + 8,000 + 70 + 6

Step-by-step explanation:

3,298,076 in expanded form =

(3×1,000,000)+(2×100,000)+(9×10,000)+(8×1,000)+(0×100)+(7×10)+(6×1)= 3,000,000 + 200,000 + 90,000 + 8,000 + 70 + 6=

3,298,076

If x + 3 is a multiple of 3, which of the following is not a multiple of 3?

(A) x

(B) x + 6

(C) 6x + 18

(D) 2x + 6

(E) 3x + 5

The answer is E because if x+3=0 then x=-1 which is the multiple of 3x-1

1)x

we have x so its -3

2)x+6

-3+6=3 its a multiple of 3 (3x1)

3)6x+18

6(-3)+18

0 is a multiple of 3 (3x0)

4)2x+6

2(-3)+6

0 is a multiple of 3

5)3x+5

3(-3)+5

-1 is not a multiple of 3

1)x

we have x so its -3

2)x+6

-3+6=3 its a multiple of 3 (3x1)

3)6x+18

6(-3)+18

0 is a multiple of 3 (3x0)

4)2x+6

2(-3)+6

0 is a multiple of 3

5)3x+5

3(-3)+5

-1 is not a multiple of 3

Answer:

If integer m is not a multiple of 3, which of the following must be true? ... of 2 let m=3K+2, (m+1)(m-1) = (3K+3)X(3K+1) is a not a multiple of 2

Step-by-step explanation:

m=4 or 5 satisfies the equation (m+1)(m-1) is a multiple of 3. Hence true.

m=4, (m+1)(m-1) = (4+1)(4-1)=15, not multiple of 2.

How many 200 mL cups can be filled from a 3 L bottle

So milileter

mili means 1000

1 leter=1000milileters

3liters=3000milileters

so

how many 200's fit into 3000

200 times what=3000

divide both sides by 200

what=15

answer is 15 of such cups can be filled

mili means 1000

1 leter=1000milileters

3liters=3000milileters

so

how many 200's fit into 3000

200 times what=3000

divide both sides by 200

what=15

answer is 15 of such cups can be filled

MIDDLE SCHOOL

21 is what percent less than 35 ?

You do this 35*x=21. and x is the percent. x=0.6. 0.6 is 60 percent. So 21 is 60 percent less than 35.

COLLEGE

Each morning, the employees in an office drink at least 73 cups of coffee. Write an inequality that represents this situation. Let c represent the number of cups of coffee.

Answer:

An inequality that represents this situation is

Step-by-step explanation:

Given : Each morning, the employees in an office drink at least 73 cups of coffee.

To find : Write an inequality that represents this situation ?

Solution :

Let 'c' represent the number of cups of coffee.

The employees in an office drink at least 73 cups of coffee.

At least means greater than or equal to i.e.

At least 73 cups of coffee is represented as

Therefore, an inequality that represents this situation is

That would be c ≥ 73 Answer
