Scientific notation is basically a shortcut for writing numbers. Scientists use it all the time if they are writing numbers that are very large or very small. If you encounter numbers that have many zeros at the end, you can use scientific notation to save your time. When using scientific notation, you're allowed to simplify all the zeros that you have in the number by writing the number as a product of a number and a power of 10.

Please help me!<br> Find AC
oksian1 [2.3K]
We are asked to find the length of AC, which measures 7x. Using the segment addition postulate, we can add the two given expressions for AB and BC and make it equal to the expression for AC. 
AB + BC=AC
5x+1+15=7x
5x+16=7x
16=2x
x=8
We've found the value of x, but we aren't done yet. We need to plug in the value we got for x into the expression for AC, which is 7x. Therefore, AC \Rightarrow7x\Rightarrow7(8)\Rightarrow\boxed{56}. Hope this helped and have a great day!

Help I’m confused on this one
Zarrin [17]

If one foot on the model represents 70 feet on the real object, the scale is 1:70. That scale applies to all dimensions and units. In other words, you can divide any object dimension by 70 to find the corresponding model dimension in the same units.

model tail height = 392 inches / 70 = 5.6 inches

model wing span = 2537 inches / 70 ≈ 36.2 inches

model length = 2785 inches / 70 ≈ 39.8 inches
