(6 · 10^5)(5 · 10^-9) ÷ (3 · 10^-3) (Express in regular numbers.

Remark

Break this down into smaller steps. Do as much as you can before considering the next part.

Step One

multiply (6*10^5) * (5 * 10^-9)

5 * 6 = 30

10^5 * 10-9 = 10^(5 - 9) = 10^-4

30 * 10^-4. But scientific notation expresses numbers between 1 and 10

30 * 10^-4 = 3 * 10^1 * 10^-4 = 3 * 10^(1 -4) = 3 * 10^-3

That's about as far as you can go with this step.

Step Two

Divide 3*10^-3 by 3 * 10^-3

When you divide anything at all by itself, you get 1.

For example 130011 / 130011 = 1

So

3 * 10^-3 divided by 3*10^-3 = 1

Answer: 1

Write the slope-intercept equation for a line that
Ber [7]

9514 1404 393

Answer:

  y = -1

Step-by-step explanation:

The slope formula tells you the slope is ...

  m = (y2 -y1)/(x2 -x1)

  m = (-1 -(-1))/(5 -3) = 0/2 = 0

We can find the y-intercept using the first point:

  b = y -mx

  b = -1 -0·3 = -1

Then the slope-intercept form is ...

  y = mx + b

  y = 0·x -1

  y = -1 . . . . . simplified

_____

Of course, you can bypass all of that when you realize the two y-values are the same, so the line is a horizontal line with y equal to that value.

25 points for this one plz help and explain how you got the answer!!
tia_tia [17]

Jorell is incorrect, because converting 18 out of 40 shots into a fraction is 18/40. In order to determine the percentage of shots which Jorell made, you can divide the two numbers. 18 divided by 40 is equal to .45. To convert .45 into a percentage, move the decimal over twice. Therefore, Jorell made 45% of the shots and not 40%.

Anton [14]

Answer:

The greatest number of t-shirts that the Sports Committee can purchase is 232.

Step-by-step explanation:

The student council raised $2,790 during its annual fundraiser.

Each t-shirt costs $12.

The total cost of buying x t-shirts is given by:

T(x) = 12x

What is the greatest number of t-shirts the Sports Committee can purchase?

The total cost has to be lesser, or equal, to 2790. So

T(x) \leq 2790

12x \leq 2790

x \leq \frac{2790}{12}

x \leq 232.5

Since you cant buy half a shirt.

The greatest number of t-shirts that the Sports Committee can purchase is 232.
