Here, we are required to determine how many hours will it be until the next instance when both foghorns sound at the same time.
The <em>lighthouse A and B </em>will have their foghorns sound at the same time after 30 hours.
- <em>Since lighthouse A sounds it's foghorn every 3hours, and lighthouse B sounds it's foghorn every 10 hours.</em>
To determine the next time when both foghorns sound at the same time;
We need to determine the lowest common multiple (LCM) of 3 and 10.
- The <em>lowest common multiple</em> of 3 and 10 is therefore 30.
As such, the foghorns sound at the same time after 30 hours of when the foghorns sounded the same time.

Answer:
115
Step-by-step explanation:
20% is one fifth. If Mary has one fifth fewer than Susan, then she has 4 fifths of what Susan has. So 92 is 4 fifths of some number.
To find out what one fifth is, you can divide 92 by 4 because it is four fifths.
92/4 = 23
So one fifth of the number of blouses Susan has is 23. Now you can multiply 23 by 5 to get the total number of blouses Susan has.
23 * 5 = 115

Answer:
73
Step-by-step explanation:
According to Triangle Sum Theorem, the 3 interior angles of a triangle adds up to 180 degrees.
So, you can take the other 2 interior angles to find the third on:
180-72-35=73
<1=73 degrees
A four sides shape is a quadrilateral.
