How do you write 3,901.25 as a scientific notation?

Mathematics

IgorC [24]3 years ago

Answer: 3.90125×10⁻³

Step-by-step explanation:

The scientific notation consists of two parts

  1. the number based: a,  where 0<a<10
  2. the exponent based: 10ˣ, which is determined by how we change the number based "a"

So the final version should be: a×10ˣ

-------------------------------------------------------------------

STEP ONE. Number based

We are given 3,901.25

In order to make it within the range of a, we should move the decimal to the left three places, or divide the number by 10³, which is times 10⁻³

We get 3.90125

STEP TWO: Exponent based

Since we changed the number by 10⁻³,  this will be our exponent-based.

Therefore, it is 3.90125×10⁻³

Hope this helps!! :)

What is the midpoint of line segment AB?
Elza [17]

Answer

Midpoint = (3, 5.5)

Step by step explanation

Here we have to use the midpoint formula.

Midpoint = ( \frac{x1 + x2}{2} , \frac{y1 + y2}{2} \\)

Here the point A = (-1, 8) and B = (7, 3)

x1 = -1, y1 = 8, x2 = 7 and y2 = 3

Now plug in these values into the formula.

Midpoint = (\frac{-1 + 7}{2} , \frac{8 + 3}{2}

= (6/2, 11/2)

= (3, 5.5)

Therefore, the midpoint the line segment AB is (3, 5.5)

Thank you.

Tanya [424]

Answer:

a) 512 cm^3

b) 469.125 cm^3

Step-by-step explanation:

8*8*8 = 512 cm^3

or

8^3 = 512 cm^3

3.5^3 = 42.875

512 - 42.875 = 469.125 cm^3

You can round the second answer down
