Answer:

If the population of the United States on July 4,2010 was almost 310000000 then, the number in scientific notation is $3.1 \times 10^{8}$.

Step-by-step explanation:

- Given

Population of the United States on July 4,2010 was almost 310000000 .

- To write the number in scientific notation.

- Firstly, move the decimal point so that the first factor is greater than or equal to 1 but less than 10 .

- Then, count the number of decimal places, n, that the decimal point was moved.

- Then, write the number as a product with a power of 10.

- Finally, check the scientific notation.

Step 1 of 2

Moving the decimal point-

Move the decimal after 3 . so that 3.10000000 is between 1 and 10 .

Now, we know the decimal point was moved 8 places to the left.

Step 2 of 2

Writing the number as a product with a power of 10 -

Since, 310000000 is greater than 1 so the power of 10 will have the exponent 8 .

Therefore, the number becomes-

$$31000000=3.1 \times 10^{8}$$

Now, checking the scientific notation-

$$\begin{gathered}3.1 \times 10^{8}=3.1 \times 100000000 \\=310000000\end{gathered}$$

Answer:

  80 square units

Step-by-step explanation:

The area formula refers to a generic triangle ABC in which side lengths 'a' and 'b' are known and angle C is between those sides.

In the given figure, we have known side lengths of 12 and 14, and the angle between them is 72°.

Putting these numbers into the formula, we find the area to be ...

  A = (1/2)(12)(14)sin(72°) ≈ 79.9 ≈ 80 . . . . square units

The area of the triangle is about 80 square units.
