Convert 0.00049 to scientific Notation

Answers

i think its 4.9 x 10-4

Answer:

It is 4.9 x 10-4

Step-by-step explanation:

So every time you do this type of scientific notation you need to count how many "0" there are and you need to check if they are in front of the number ( ex: 74.000 ) or if the are in the back ( ex: 0.0074 ) In this case since is in the back you would get the 10 and put it to the power of -4 since there is 4 zeros behind it. and then you just get the " 4 9 "( put a " . " between it ) and multiply it by 10^(-4). ( You don't need to actually do the multiplication unless your teacher ask you to )

Sales for a business were 3 million dollars more the second year than the first, and sales for the third year were double the sales for the second year. If sales for the third year were 38 million dollars, what were sales, in millions of dollars, for the first year?A. 16
B. 17.5
C. 20.5
D. 22
E. 35

Answers

The sales in million of dollar, for the first year is 16 million in dollars.

What are sales ?

"In general business operations, sales refer to any transactions where money or value is exchanged for the ownership of a good or entitlement to a service."

Given,

The sales for the third year is 38 million dollars.

Let the sales for the first year be x

and the sales for the second year be y

So, x+3 = y;

Sales for the third year = \ 2(x+3)

\38 = 2(y)38 = 2(x+3)

i.e. x = 16

Hence, option A is correct.

How does your answer help you solve a division equation such as x/7 =2 ?

Answers

dunno

I can solve it though
x/7=2
multiply both sides by 7
x/7 times 7/1=2 times 7
7x/7 =14
7/7 times x/1=14
1 times x=14
x=14


answer is 14

hmm, maybe multiply bottom number by the one on the other side of the equal sign
You plug in your answer for x and solve it to see if it = 2. So x=14. You plug it back into the equation. 14/7=2
2=2
Your answer is correct.
