BARSIC [14]

Hey there!

3.0 * 10^8

= 3.0 * 10 * 10 * 10 * 10 * 10 * 10 * 10 * 10

= 3.0 * 100 * 100 * 100 * 100

= 3.0 * 10,000 * 10,000

= 3.0 * 100,000,000

= 300,000,000

Therefore, your answer is:

300,000,000

Good luck on assignment & enjoy your day!

Three consecutive integers are n, n, +1 and n+2. 4 times the sum of the least and greatest integers is 12 less than three times

raketka [301]

Answer:

The smallest integer is -4.

Step-by-step explanation:

4(n + n+2) = 3*n - 12 Combine the left

4(2n + 2) = 3n- 12 Remove the brackets

8n + 8 = 3n - 12 Subtract 3n from both sides

8n-3n + 8 = 3n-3n - 12 Combine

5n + 8 = - 12 Subtract 8 from both sides

5n = - 12 - 8

5n = - 20 Divide by 5

5n/5 = -20/5

n = - 4

n + 1 = -3

n + 2 = - 2

Scientists are examining two different strains of a particular bacteria. The length of one strain of the bacteria measures 0.000

vesna_86 [32]

Scientists are examining two different strains of a particular bacteria. The length of one strain of the bacteria measures 0.000000368

mm, while the length of the second strain measures 0.000000064 mm. How much larger is the first strain than the second?

We can figure this out using scientific notation.

$0.000000368 - 0.000000064$

$= 3.04e-7$

Put 3.04e-7 in standard notation.

$0.00000304$

Put 0.00000304 back into scientific notation, instead with a multiply sign.

Move the dot back, making the number in between 1-10.

In this case, we would move it back 7 times.

$3.04$ · $10x^{-7}$

So the answer would be A.
