Hello! I can help you with this! Finding scientific notation comes with a decimal that’s greater than 1, but less than 10 times 10 to a power. In this case, the answers would be:

a. 5.8 * 10^7
This is because 10^7 power is equivalent to 10,000,000 and multiply both answers to get the number of the average distance between sun and Mercury.

b. 2.5 * 10^-3
Because the answer is a small decimal, we have to do negative powers and move the decimal to the left of the number. In this case, you move the decimal to the left three times to get the number.

Can u plz help me answer question 30
slamgirl [31]

We are given:

3x^3-2x^2

There seems to be nothing I can do to simplify this equation. However, I can factor out an x^2 since they both have at least an x^2. Here is what we get:

x^2(3x-2)

This is in the simplest form I can get into. I cannot do anything more to simplify this expression. This is your final answer.

A total sales amount of $400,000 that included a 6% sales tax yields actual sales of
d1i1m1o1n [39]

Answer:

$377,358.49

Step-by-step explanation:

Let, the actual sales = $X

Given total sales amount including 6% of sales tax = $400,000

Therefore, (X+6% of X)= $400,000

⇒(X+X·6÷100)= $400,000

⇒(X+0.06X)= $400,000

⇒ 1.06X= $400,000

∴ X= $400,000÷ 1.06 = $ 377,358.49

Hence, the actual sales = $ 377,358.49
