The range of a lighthouse is the maximum distance at which its light is visible. In the figure, point A is the farthest point fr

om which it is possible to see the light at the top of the lighthouse L. The distance along Earth, s, is the range. Assuming that the radius of the Earth is 4000 miles, find the range of Marblehead Lighthouse to the nearest tenth of a mile. Enter only the number. (Hint: Notice the right triangle EAL with right angle A. Find the length EL, then subtract the radius of the Earth to find the height of the lighthouse.)

alvin and simon raced a distance of 2.9 x 10^2 kilometers. they need to race 7 times that distance in kilometer. how far must th
dimaraw [331]

The distance in kilometers in scientific notation 2.03 \times 10^3 km

<h3>Scale factors</h3>

Scale factors are values or constants multiplied with a variable

If Alvin and Simon raced a distance of 2.9 \times 10^2 kilometers and they need to race 7 times that distance in a kilometer, the distance traveled will be:

  • Distance travelled = 7(2.9 \times 10^2)
  • Distance travelled = 2.03 \times 10^3 km

Hence the distance in kilometers in scientific notation 2.03 \times 10^3 km

How do you right 0.0001 in expanded form
kirza4 [7]

The expanded form of the number 0.0001 is \bold{\frac{1}{10000}}.

<u>SOLUTION: </u>

Given that, we have to write 0.0001 in expanded form.

Expanded form or expanded notation is a way of writing numbers to see the math value of individual digits. When numbers are separated into individual place values and decimal places they can also form a mathematical expression.

Now, take the given number 0.0001

As there are no other digits except 0 in front of 1 our work is simplified.

Expanded form will be \frac{1}{10000}

Hence, the expanded form of the number 0.0001 is \frac{1}{10000}.

Then just put the eggs according from least to greatest:
 
1st egg:43.98

2nd egg:45.02

3rd egg:45.07
