Rewrite the following statement using a number in scientific notation.

Mathematics

Mila [183]3 years ago

Answer:

3.1 x 10^11

Step-by-step explanation:

Since we know that giga means billion, we can piece together that 310 gigabytes = 310 billion

310 billion = 310,000,000,000

When writing in scientific notation, we move the decimal point over until there is only a single digit to the right of the decimal point.

Currently the decimal point is all the way at the end of the 310 billion.

310,000,000,000.

We need to move it over to the left, keeping count of how many times we do so, and stopping when there is only one digit to the right of the decimal.

We end up with: 3.10000000000 or 3.1

We moved the decimal over 11 times. This can be represented by the value 10^11 (pronounced as "10 to the 11th power")

Now, we combine these two to create 3.1 x 10^11

We must multiply the 3.1 by 10^11 in order to create the same amount as 310,000,000,000 (310 billion). If we were to leave 3.1 alone, it would not represent 310 billion.

Thus, we leave this as 3.1 x 10^11 which is scientific notation.

  • Left to Right

<u>Algebra I</u>

  • Function Notation

Step-by-step explanation:

<u>Step 1: Define</u>

f(x) = 3x² + 2x - 3

f(3) is x = 3

<u>Step 2: Evaluate</u>

  1. Substitute in <em>x</em>:                    f(3) = 3(3)² + 2(3) - 3
  2. Exponents:                          f(3) = 3(9) + 2(3) - 3
  3. Multiply:                               f(3) = 27 + 6 - 3
  4. Add:                                     f(3) = 33 - 3
  5. Subtract:                              f(3) = 30

Find the length of arc AB for each circle.
Eddi Din [679]

Answer:

see explanation

Step-by-step explanation:

The length of the arc is calculated as

AB = circumference of circle × fraction of circle

(11)

AB = 2πr × \frac{90}{360}

     = 2π × 7 × \frac{9}{36}

     = 14π × \frac{1}{4}

     = \frac{7}{2} π in

(12)

AB = 2πr × \frac{135}{360} ( r = 20 ÷ 2 = 10 )

      = 2π × 10 × \frac{3}{8}

      = 20π × \frac{3}{8}

      = \frac{60}{8} π

      = \frac{15}{2} π cm

A train leaves at 17.22 and arrives at its destination at 18.14.
sattari [20]

Answer:

64.6 km/h

Step-by-step explanation:

18:14 = 18h 14'

1h = 60'

18h = 17h + 60'

18h14' = 17h + 60' ´14' = 17h 74'

then:

17h 74'

-17h 22'

= 0h 52'

the train travelled 56km at 52 minutes

56km/52minutes

1 hour = 60 minutes

52 minutes = 52/60 = 0.86667 hours

then:

56km/52minutes = 56km/0.86667hours

= 64.615 km/hours
