Answer:
<h2>IJ is 3.1 feet long, approximately.</h2>
Step-by-step explanation:
In the image attached you can observe a representation of the problem.
Notice that we must find the hypothenuse of the right triangle. So, we need to use trigonometric reasons, because we have one angle and its opposite leg, that means we can use the sine reason.

Therefore, IJ is 3.1 feet long, approximately.
Answer:
5 × 
Step-by-step explanation:
A number in standard form is
a ×
where 1 ≤ a > 10 and n is an integer
Given
0.005 ← express as a number between 1 and 10
= 5 ×
n is the value required to move the decimal point back to its original position
A move to the right is +
A move to the left is -
Here we require to move the decimal point back 3 places to the left
Thus
0.005 = 5 ×
