<span>To do this you need to multiple 1,024 by 1,000,000 to get 1,024,000,000 and then convert it to scientific notation. For that you need to know how many places there are after the first number. In this case it is 9. This will be 1.024 x 10^9. You have to remember that it is to the power of however many numbers are after the first. So even though we show 3 digits after the . we still have to include those in the power.</span>

Answer:

4.869 × 10³⁰ milligrams        

Step-by-step explanation:

A number written in scientific rotation is a number between 1 and 10 multiplied with the power of 10.

We know that

1 kilogram = 1,000,000 milligrams =1.0 × 10⁶ milligrams

4.869 × 10²⁴ kilograms can be written as:

4.869 × 10²⁴ × 1.0 × 10⁶ milligrams = 4.869 × 10³⁰ milligrams

IA triangular parking lot is paved outside a new shopping center. The lengths of the sides of the parking lot are 100 meters, 11
Gemiola [76]

Answer:

Step-by-step explanation:

I believe the only way to solve this is by Heron's Formula.

Add up all the sides and divide by 2 to get the semi-perimeter:

113+100+86 = 299

299/2 = 149.5

Now fill in the rest, which looks like this:

\sqrt{s(s-a)(s-b)(s-c)}

where s is your semiperimeter value, a is the length of one side, b the length of another side, and c the length of the third side:

\sqrt{149.5(149.5-113)(149.5-100)(149.5-86)}

which simplifies to

\sqrt{149.5(36.5)(49.5)(63.5)}

which simplifies further to

\sqrt{17151929.44}

which, on your calculator, is 4141.49 meters squared (that's rounded to the nearest hundredth).
